Trane OIL00048 is a refrigeration and compressor oil that Trane publishes in its own parts catalogue under the product name OIL; REFRIGERATION LUBRICANT ISO 68 POLYOLESTER 1 GALLON. The manufacturer's own name states the class and the chemistry — ISO 68 and polyolester — so the grade is quoted from Trane rather than derived, and it is the ISO VG 68 band (ISO VG 68 band (61.2–74.8 cSt at 40 °C)) defined by ISO 3448. It is the oil Trane specifies for every RTHC, RTWD and RTAC chiller, and the one RTHD takes when it has a wye-delta starter, and the manufacturer lists it for RTHC, RTWD and RTAC chillers without exception, and RTHD chillers fitted with a wye-delta starter.
We manufacture and supply refrigeration and compressor oils at our own blending plant in Foshan, China. For this grade our equivalent is QSL-68H. It ships from Guangzhou Port, which is next to the plant. There is no fixed minimum order — it is confirmed per order, because a single can and a full container load are both workable and the figure moves with the pack size, the quantity and the destination. Delivery is on any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — and payment is on any commonly used method, including T/T, L/C and PayPal.
QISHANR is a refrigeration oil manufacturer and wholesale supplier, and this grade is supplied in bulk to distributors, HVACR service companies and compressor OEMs worldwide.
Trane OIL00048 is supplied on published terms: the specification, the price terms, the payment terms and the documents are the same for every buyer, and they can be quoted without a site visit. The minimum order is deliberately left open, because it is judged case by case: the part number, the quantity, the pack size, the shipping terms and the container load all move it, so a single can and a full container load are both workable and neither is treated as the normal case. Send us the chiller model, the part number on the nameplate and the destination port, and those three turn the table below into a firm quotation. Documents and lead time work the same way on every order: the technical data sheet and safety data sheet come with the quotation, and the certificate of analysis for the delivered batch comes with the shipment. This grade is supplied wholesale and in bulk — to distributors, HVACR service companies, compressor OEMs and private-label buyers — as well as in single packs and sample quantities.
| Item | Terms for Trane OIL00048 |
|---|---|
| Minimum order quantity | Not a fixed figure — confirmed per order, because it is judged case by case: the grade, the pack size, the quantity, the shipping terms and the container load all move it, so a single can and a full container load are both workable |
| Payment terms | Any commonly used payment method — T/T, L/C, PayPal and every other option — confirmed with the order |
| Price terms | Any Incoterms 2020 term — EXW, FOB, CFR, CIF, DDP and every other rule — quoted against your destination port |
| Supply ability | 1,000 pieces per year on this grade, at our blending plant in Foshan — this is the figure for our equivalent, not the annual capacity of the plant |
| Origin | The original Trane product, or an equivalent manufactured at our own plant in Foshan, China |
| Supply options | The original Trane OIL00048 oil, or QSL-68H (our own ISO VG 68), manufactured at our blending plant in Foshan, China |
| Who buys this grade | Distributors and resellers who stock refrigeration oil, HVACR and refrigeration service companies, chiller maintenance contractors, and buyers who need private-label or own-brand packing. Wholesale and bulk orders are the norm; trial and sample quantities are also supplied. |
| Grade confirmation | Send the chiller model, the refrigerant and the part number stamped on the nameplate. Trane publishes this part number as an ISO 68 polyolester, and we confirm that it is the right grade for your machine before quoting |
| Viscosity | ISO 68, stated by the manufacturer in its own product name — the ISO VG 68 band, ISO VG 68 band (61.2–74.8 cSt at 40 °C). Trane does not publish a measured 40 °C figure for the part number, so the class is quoted as the manufacturer states it |
| Pack size | The manufacturer publishes this part number as 1 gal. We supply the pack format you need, and custom pack formats are available as a quotation item. |
| Documents issued with the order | Technical data sheet, safety data sheet, and a certificate of analysis for the delivered batch |
| Handling and storage | Store sealed, away from direct sunlight, and keep the container closed between top-ups. A polyolester charge is hygroscopic, so a container is kept sealed until the moment it is used and the circuit is not left open. Never mix different oil types, brands or additives. Trane's own position on additives is explicit: no additive has ever been endorsed or approved by Trane, and the manufacturer states that Trane oils are the only oils approved for use in its equipment. |
Supply ability is stated for this grade rather than for the plant as a whole. It is not the annual capacity of the blending plant.
A lubricant order is rarely only a lubricant order. The buyer is usually solving a grade question, an import documentation question, a freight question and a packaging question at the same time — often across more than one product family. Those are the parts of the job we take on, and they are handled by the same team that quotes the oil rather than passed to a third party.
We are a manufacturer rather than a reseller, which is what makes that possible. The blending plant in Foshan, Guangdong runs at 6,000 tonnes a year and has been producing lubricants for more than ten years, so the answer to most of the questions below comes out of our own production and our own paperwork.
| What you are dealing with | What we do about it |
|---|---|
| The nameplate names a part number and you need to know what it is equivalent to | Send us the chiller model, the refrigerant and the part number on the nameplate. Trane publishes this part number as an ISO 68 polyolester, so it can be matched on the ISO VG 68 class rather than on a description, and we confirm the match in writing before you order. |
| You need the grade, not a catalogue description | Every figure on this page is traceable to a document published by Trane or by Lubrizol, and the sources are linked at the foot of the page. Where the manufacturer publishes nothing for a property, this page says so instead of filling the gap. |
| You are buying alongside other oils and want them on one order | Refrigeration oils are the core of our business, not the whole plant. The same lines produce air compressor oils, vacuum pump oils and general industrial lubricants, and a mixed enquiry can be quoted, packed and shipped together rather than split across suppliers. |
| You need documentation for customs or for a tender | CE, CO, MSDS and transport certification are issued as standard documents with an export order. Tell us at the enquiry stage which certificate the destination requires and we compile the file with the quotation rather than after the shipment. |
| You are changing a machine over from another oil | Trane's own instruction is never to mix different oil types, brands or additives, and the manufacturer states that gauges and recovery equipment should be dedicated to a particular refrigerant family rather than shared. Where a machine is being changed over, the old charge is drained and the circuit flushed and evacuated rather than topped up. Tell us what is coming out and what is going in, and we will confirm the changeover procedure with the oil. |
The point of this list is that the questions are answered before the order rather than after it. If you are unsure which of them applies to you, describe the system and we will tell you what we need.
Grade confirmation comes before pricing, because Trane's part numbers separate oils by both grade and refrigerant family, and mixing the families is the mistake that costs a compressor. The sequence is the same whether you are buying one can or a full container:
If you already know the part number and only need a price, send the quantity and the destination port and we will quote directly.
Trane publishes this part number as a catalogue item rather than as a typical-properties sheet. The table below separates what the manufacturer does publish — the official product name, the viscosity designation, the oil type, the refrigerant and the equipment the oil goes into — from what it does not, with the source of each row. The grade is quoted on the ISO 3448 scale because Trane itself states ISO 68 in the product name.
| Property | What Trane publishes | Source |
|---|---|---|
| Official product name | OIL; REFRIGERATION LUBRICANT ISO 68 POLYOLESTER 1 GALLON | Trane Supply — official parts catalogue (part number OIL00048) |
| Oil type | Polyolester (POE) | Trane Supply — official parts catalogue |
| Viscosity designation | ISO 68 — the manufacturer's own product name states ISO 68 and polyolester, so the class is quoted from the manufacturer rather than derived | Trane Supply — official parts catalogue |
| ISO viscosity grade | ISO VG 68 — stated by the manufacturer in its own product name | Derived |
| Kinematic viscosity at 40 °C | Not published by the manufacturer for this part number | Trane Supply — official parts catalogue |
| Refrigerant | R-134a | Trane — Trane Recommended Oil (commercial HVAC help centre) |
| Chiller and compressor types | RTHC, RTWD and RTAC chillers without exception, and RTHD chillers fitted with a wye-delta starter | Trane — Trane Recommended Oil (commercial HVAC help centre) |
| Pack size and part number | 1 gal container (part number OIL00048) | Trane Supply — official parts catalogue |
| Supersession | None published for this part number | Trane Supply — official parts catalogue |
| Density, viscosity index, flash point, pour point | Not published — the manufacturer publishes no typical-properties sheet for this part number, so these four are not available from a manufacturer source | Trane Supply — official parts catalogue |
Where a value is published by the manufacturer, the source row shows which document it comes from. The viscosity designation is quoted exactly as Trane writes it, because on this range the manufacturer states the grade in its own product name rather than as a measured figure. Where Trane publishes nothing for a property, this page says so rather than quoting a value from a reseller.
There is no typical-properties sheet to read for this part number, so the decisions have to be made on the manufacturer's designation and on the machine. These are the points that matter.
| Parameter | Position for Trane OIL00048 | What it means for the order |
|---|---|---|
| Viscosity designation | ISO 68 | This is the manufacturer's own designation, taken from the product name in its parts catalogue, and it is the figure a Trane parts order is matched on. |
| ISO viscosity grade | ISO VG 68 — ISO VG 68 band (61.2–74.8 cSt at 40 °C) | The class is what a replacement is compared on, and it is why a buyer looking for an ISO 68 grade is pointed at this part number. Trane does not publish a measured 40 °C figure, so the class is quoted as the manufacturer states or designates it. |
| Oil type | Polyolester (POE) | This is the manufacturer's own description, taken from the product name in its parts catalogue. |
| Refrigerant | R-134a | The refrigerant family is the figure that separates the oils that must never be mixed, so it is checked before the part number is confirmed. |
| Equipment | RTHC, RTWD and RTAC chillers, and RTHD chillers with a wye-delta starter | This is the manufacturer's own application statement, and it is the reliable part of the published record for this part number. |
| Grade substitution | Check the nameplate first | Trane's own article ends with the instruction to verify the oil type stamped on the chiller nameplate, and the same instruction is repeated for the equipment covered by its oil bulletin. That instruction applies with more force on a part number whose full property set is not published. |
The pattern across this range is that Trane publishes the designation and the application, and leaves the physical property sheet to the oil supplier. That is why the table above is built on designations rather than on measured values.
Trane's oils are separated by the refrigerant family and by the compressor starter on the unit, and the manufacturer publishes a different amount of information about each one. The table shows the range as Trane publishes it, with this product marked: the official product name, the ISO position where one can be stated, the refrigerant, and the equipment the manufacturer lists.
| Part number | Trane's official product name | ISO 3448 position | Refrigerant | Equipment the manufacturer lists |
|---|---|---|---|---|
| OIL00015 | OIL; COMPRESSOR, 300 SUS | No ISO class — designated 300 SUS | R-22 | RTHA / RTHB R-22 water-cooled chillers on standard-temperature duty; DX-evaporator R-22 chillers; Pueblo-built R-22 scroll chillers. Superseded by OIL00031. |
| OIL00022 | OIL; CENTRIFUGAL, WHITE MINERAL REFRIGERANT, GRADE 68 | ISO VG 68 (Grade 68) | Not published | Centrifugal chillers |
| OIL00031 | OIL; COMPRESSOR; 300 SUS | No ISO class — designated 300 SUS | R-22 | RTHA / RTHB R-22 water-cooled chillers at 38 °F leaving water or below; all R-22 helical rotary chillers; Pueblo-built R-22 scroll chillers |
| OIL00037 | OIL; REFRIGERATION, R-134, GRADE 68 | ISO VG 68 (Grade 68) | R-134 | Not published beyond the refrigerant |
| OIL00048 (this product) | OIL; REFRIGERATION LUBRICANT ISO 68 POLYOLESTER | ISO VG 68 (stated by the manufacturer) | R-134a | RTHC, RTWD and RTAC chillers without exception; RTHD with a wye-delta starter |
| OIL00049 | OIL; REFRIGERANT (R-134), GRADE 68 | ISO VG 68 (Grade 68) | R-134 | Not published beyond the refrigerant |
| OIL00311 | Bulk pack of the Solest 120 polyolester oil | No ISO class — designated 120 grade | R-134a | RTHD with an AFD starter; RTAE and RTAF |
| OIL00315 | OIL; LUBRICANT, SOLEST 120 POE-OIL, 120 GRADE POLYOLESTER OIL | No ISO class — designated 120 grade | R-134a | RTHD with an AFD starter; RTAE and RTAF |
| OIL00317 | OIL; LUBRICANT, SOLEST 120 POE-OIL, 120 GRADE POLYOLESTER OIL | No ISO class — designated 120 grade | R-134a | RTHD with an AFD starter; RTAE and RTAF |
Product names are reproduced from the Trane Supply catalogue, which is the parts document a Trane service contractor works from. Where a part number is shown as having no ISO class, the manufacturer designates it in SUS or in its own grade numbering rather than on the ISO 3448 scale. OIL00311, OIL00315 and OIL00317 are the same oil published in three pack sizes.
If this part number is not the one you need, the sections below show where it sits against the rest of the Trane range and against the oils we manufacture ourselves, so a substitution can be checked before it is ordered.
| Brand | Grade | Viscosity position | Note |
|---|---|---|---|
| Qishanr | Polyol ester (POE) refrigeration oil | QSL-68H — our own ISO VG 68 grade | Our own equivalent, blended in Foshan, China, and named here rather than described: QSL-68H |
| Trane | Trane oil range | 300 SUS to ISO 68 | The full published range from the same manufacturer; Trane OIL00048 is the oil Trane specifies for every RTHC, RTWD and RTAC chiller, and the one RTHD takes when it has a wye-delta starter |
| Trane | Trane OIL00315 | Solest 120 POE | Another part number in the same range, published with its own designation |
| Trane | Trane OIL00049 | Grade 68 | Another part number in the same range, published with its own designation |
A substitution should be made on the refrigerant family and on the measured viscosity at 40 °C where one is published, not on the part number alone. Trane's own instruction is that its oils are the only oils approved for use in its equipment and that no additive has ever been endorsed or approved, so any equivalent is quoted as an alternative rather than as an approved replacement.
Trane publishes this part number with the grade in the product name: OIL; REFRIGERATION LUBRICANT ISO 68 POLYOLESTER 1 GALLON. That name states ISO 68 and polyolester directly, so the class on this page is not an interpretation — it is the manufacturer's own wording, and it sits inside the ISO VG 68 band (61.2–74.8 cSt at 40 °C).
The reason the class matters more than the brand on a chiller oil is that the compressor loads its oil in several places at once. The bearings and the shaft seals rely on the working viscosity to carry load, the compression element relies on it to seal, and the oil separator relies on the oil behaving predictably across the whole temperature range. A grade that is one ISO step away is not a small difference in a machine that was designed around a particular film thickness.
The oil in a chiller is chosen from the unit, not from the container size. Trane separates its oils by refrigerant family first and by grade second, which is why the same compressor family takes different part numbers depending on the starter fitted and why the manufacturer's article repeats the instruction to verify the oil type stamped on the nameplate.
The figure to work from is the part number on the machine and the refrigerant it holds. That is the point at which we confirm the grade against the published data before quoting, and it is also why this range carries more than one part number for what looks like the same duty.
Every figure on this page comes from a document published by Trane. Where the manufacturer states a value in its own product name, the name is reproduced in full rather than paraphrased, because on this range the product name is the specification.
It also means a buyer can check a figure rather than take it on trust. Where a value is published, the source column shows which document it comes from, and where the manufacturer publishes nothing for a property the page says so rather than filling the gap with a figure from a reseller.
ISO 3448 does not define a continuous scale of viscosity. It defines a series of discrete classes, each a band of permitted viscosity at 40 °C — ISO VG 68 band (61.2–74.8 cSt at 40 °C) is the band this part number is assigned to — and a grade is assigned to a class on its measured or designated figure.
Trane states ISO 68 in the product name for this part number, so the class is quoted here as the manufacturer's own designation. What a buyer should match, in the end, is the class and the refrigerant family: the class is the figure the compressor was designed around, and the refrigerant family is the figure that decides which oils must never be mixed.
Trane's part numbers separate oils by refrigerant family, and the manufacturer states plainly that its R-22 oils and its R-134a oils must never be introduced into each other's systems. A quotation that skips the part number check is a price for a product that may not fit the unit it is going into, and the cost of that mistake is a compressor rather than a drum of oil.
So the sequence is fixed: send the chiller model, the refrigerant and the part number stamped on the nameplate, and we confirm the grade against the manufacturer's published data before the price is issued. That is also what makes the specification comparable on a page like this one, because every figure is tied to a published document rather than to a description.
We manufacture lubricants at our own blending plant in Foshan, Guangdong, which runs at 6,000 tonnes a year and has been producing for more than ten years. That is what allows us to quote a grade at this class from our own line (our QSL-68H) against the Trane specification, and to hold stock on the grades we list rather than promising on behalf of a third party.
It also means the answer to a question about the oil comes from the plant rather than from an intermediary. If you need the grade matched to a chiller model, or to know which documents come with the shipment, tell us at the enquiry stage and we will confirm it against your destination rather than leave it until the order is placed.
Alongside the refrigeration oils the same plant produces air compressor oils, vacuum pump oils and general industrial lubricants, so a mixed enquiry can be quoted, packed and shipped as one shipment rather than split across suppliers.
A: There is no fixed minimum order — it is confirmed per order, because it depends on the pack size, the quantity and the destination, and a single can and a full container load are both workable. The manufacturer publishes this part number as 1 gal, and custom pack formats and private-label artwork are available as a quotation item, so if your own label has to go on the container, say so when you enquire and it is quoted as part of the project rather than added afterwards.
A: Trane OIL00048 is a refrigeration and compressor oil that Trane publishes in its own parts catalogue under the product name OIL; REFRIGERATION LUBRICANT ISO 68 POLYOLESTER 1 GALLON, listed by the manufacturer for RTHC, RTWD and RTAC chillers without exception, and RTHD chillers fitted with a wye-delta starter. Trane states the class in the product name as ISO 68, a polyolester, and the manufacturer's own article sets out which chillers take which part number.
A: Both are part numbers in the same Trane oil range but they are separated by the refrigerant family and the equipment the manufacturer lists. Trane OIL00048 is published as Grade 68 for R-134a, while Trane OIL00315 is published as Solest 120 POE. They are not interchangeable, and on this range mixing the refrigerant families is the failure mode the manufacturer warns about. Send us the chiller model, the refrigerant and the nameplate part number and we will confirm which of the two matches the machine.
A: Trane publishes this part number for R-134a. The manufacturer's article states that RTHC, RTWD and RTAC chillers use Oil 48 without exception, and that it is a polyolester oil specifically formulated for use with R-134a. It also states that Oil 48 is not compatible with Oil 15 and Oil 31 and can never be introduced into R-22 systems, and that catastrophic failure results if Oil 15 or Oil 31 is introduced to R-134a systems.
A: Yes. The manufacturer states ISO 68 in its own product name for this part number, so the class is quoted directly from Trane. Match on the class and on the refrigerant family as well, because those are what the machine was built around.
A: No — and on this part number the manufacturer's warning is the strongest in the range. Trane states that Oil 48 is not compatible with Oil 15 and Oil 31 and can never be introduced into R-22 systems, and that catastrophic failure results if Oil 15 or Oil 31 is introduced to R-134a systems. Gauges and recovery equipment are kept dedicated to one refrigerant family rather than shared between the two. Where a machine is being changed from one oil to another, the changeover is carried out as a changeover rather than a top-up: the old charge is drained, the circuit is flushed and evacuated, and the new charge goes in clean. Confirm the changeover procedure with us before the system is charged.
A: Trane publishes the part number as a catalogue item: the official product name, which carries the viscosity designation, the oil type and the pack size; the refrigerant and the equipment it goes into, from the manufacturer's recommended-oil article; and, where applicable, the part number that supersedes it. It does not publish a typical-properties sheet for this part number, so density, viscosity index, flash point and pour point are not available from a manufacturer source, and this page states that rather than filling it in.
A: Yes. Private-label artwork and custom pack formats are a normal quotation item, and the container is packed at our plant in Foshan. Tell us at the enquiry stage that your own label is required, and the artwork and the pack are quoted together with the oil rather than added afterwards.
A: Store it sealed, away from direct sunlight, and keep the container closed between top-ups. A polyolester charge is hygroscopic, so the container stays sealed until the moment it is used and the circuit is not left open. Never mix different oil types, brands or additives, and do not decant into an unlined steel drum where the oil can pick up rust and moisture.
Every figure on this page is taken from a document published by the brand owner rather than from our own measurement, so each one can be checked before you buy. This is the set of sources, with what each one establishes.
| Source | What it establishes |
|---|---|
| Trane — Trane Recommended Oil (commercial HVAC help centre) | The manufacturer's own statement of which oil goes into which chiller. It establishes the part-number map across this range: RTHA and RTHB R-22 water-cooled chillers nameplated for Oil 15 or Oil 31; every R-22 chiller built at Trane-Pueblo charged with Oil 31 regardless of nameplate; RTHC, RTWD and RTAC chillers on Oil 48 without exception; RTHD chillers split by starter between Oil 48 and Oil 315; RTAE and RTAF on Oil 315; and the Pueblo-built R-22 scroll chillers on Oil 31 or Oil 15. It is also the source of the compatibility warning and of the manufacturer's position on oil additives. |
| Trane Supply — official parts catalogue, part number OIL00048 | The official product name for this part number: OIL; REFRIGERATION LUBRICANT ISO 68 POLYOLESTER 1 GALLON. It is the source of the viscosity designation, the oil type and the pack size quoted on this page, and of the supersession where one applies. The full Trane Supply oil listing carries the same names for the rest of the range. |
| ISO 3448:1992 — Industrial liquid lubricants — ISO viscosity classification | The standard that defines the discrete viscosity classes at 40 °C. The class quoted on this page (ISO VG 68, the ISO VG 68 band (61.2–74.8 cSt at 40 °C)) comes from that classification, and it is the reason the grade is compared on a class rather than on a grade letter. |
Where a value is published by the manufacturer in its own product name, the name is reproduced in full so the value can be traced to the catalogue entry rather than treated as a general property. Where the manufacturer publishes nothing for a property, this page says so rather than quoting a value from another source.
This oil is manufactured and supplied by Guangzhou Qishanr Technologies Co., Ltd., trading as the brand QISHANR. The company is based in Foshan, Guangdong, adjacent to Guangzhou Port, and has been producing lubricants for more than 10 years from its own blending plant. That plant runs at an annual capacity of 6,000 tonnes, which is what allows us to hold stock on the grades we list and quote firm lead times rather than promising on behalf of a third party.
Refrigeration oils are the core of the business, but they are not the whole plant. The same lines produce general industrial lubricants, so a mixed enquiry that covers both refrigeration oils and ordinary industrial grades can be quoted, packed and shipped together instead of being split across suppliers.
This is not the full range. Specialised ester base oils and lubricant additives are produced in-house as well, which is the reason the synthetic ester grades can be specified to a target rather than bought off a shelf. If the grade you need is not listed above, send the specification or the product you are replacing and we will confirm whether we produce it.
Long-term partners get pricing that reflects a stable manufacturing base rather than a trading margin, and the same technical contact stays with the account from grade selection through to repeat orders.
Trane OIL00048 is quoted on the part number, the pack size and the destination port rather than on a list price. Send your chiller model, the refrigerant, the part number stamped on the nameplate and the quantity you need. We will confirm the grade against the manufacturer's published data — including whether your machine takes this part number or the one next to it, and which refrigerant family it belongs to — and come back with pricing, pack size and lead time. A technical data sheet and safety data sheet come with the quotation, and we can quote our own equivalent side by side so the comparison is on landed cost.
