Solest 120 is a synthetic polyol ester (POE) refrigeration compressor lubricant with a kinematic viscosity of 127.7 cSt at 40 °C. That figure falls between the ISO VG 100 band (90–110 cSt) and the ISO VG 150 band (135–165 cSt) defined by ISO 3448, so the grade carries no ISO VG class number — the manufacturer designates it 120. It is the lighter of the high-viscosity grades in the Solest range made by CPI Fluid Engineering, the compression and refrigeration fluids business of The Lubrizol Corporation, and the range is described by its manufacturer as developed for HFC, HCFC and HFO refrigeration and for reciprocating, screw and centrifugal compressors. Solest lubricants are designed for standard factory fill of air-conditioning and industrial refrigeration equipment as well as for OEM retrofitting, and the manufacturer states that the range has been in field service for more than 25 years.
We manufacture and supply this viscosity ourselves, at our own blending plant in Foshan, China — our equivalent is a polyol ester (POE) grade at the same measured viscosity. 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 — send the compressor model, the refrigerant and the system's evaporating temperature and we will confirm the grade against the Lubrizol data before quoting.
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.
Solest 120 is supplied on published terms: the measured viscosity, 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 grade, 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 quantity, the destination port and whether your own brand goes on the container, 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 Solest 120 |
|---|---|
| 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 at this viscosity, not the annual capacity of the plant |
| Origin | The original Lubrizol Solest product, or an equivalent manufactured at our own plant in Foshan, China |
| Supply options | The original Lubrizol Solest 120, or our own polyol ester (POE) grade at the same measured viscosity, manufactured at our blending plant in Foshan, China |
| Who buys this grade | Distributors and resellers who stock refrigeration oil, HVACR and refrigeration service companies, compressor OEMs filling new equipment, 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 compressor model, the refrigerant and the evaporating temperature. The Solest range covers 22 to 370 cSt at 40 °C across its grades and several of the heavier ones carry no ISO VG class number, so the grade is matched on the measured 40 °C viscosity rather than on a class label; Solest 120 measures 127.7 cSt, and we confirm that it is the right viscosity for your system before quoting |
| Viscosity | 127.7 cSt at 40 °C, which falls between the ISO VG 100 band (90–110 cSt) and the ISO VG 150 band (135–165 cSt) defined by ISO 3448 — so there is no ISO VG class number to quote, and the manufacturer designates the grade 120 |
| Pack size | Confirmed at quotation. The manufacturer states that the Solest range is available in a variety of packages; 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 — polyol ester oils absorb moisture from the air, and moisture is what shortens their service life. Do not decant into an unlined steel drum. |
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. The enquiries that reach us on this grade are consistent: the buyer has a high-viscosity refrigeration compressor, a data sheet in hand, and needs to know whether the two match.
| What you are dealing with | What we do about it |
|---|---|
| The compressor data sheet names a viscosity, not an ISO VG class, and you cannot tell which class that is | That is normal for this grade. Solest 120 measures 127.7 cSt at 40 °C, which falls between the ISO VG 100 band (90–110 cSt) and the ISO VG 150 band (135–165 cSt) defined by ISO 3448, so there is no class number to convert it to. Send the compressor model, the refrigerant and the operating temperatures and we match the grade on the measured viscosity, in writing, before you order. |
| You have an industrial refrigeration compressor and the OEM data sheet names a grade you cannot source locally | Send the compressor model, the refrigerant and the oil that is named. We hold the Lubrizol published data for the Solest range, so the grade can be matched against the specification rather than against a description, and we can quote the original grade or our own equivalent at the same viscosity side by side so the comparison is on landed cost. |
| You have the Lubrizol data sheet and need the grade to match it | We confirm the measured viscosity and the base oil type against the Lubrizol data for this grade, and we supply to that specification rather than to a generic description. Every figure on this page is traceable to the published document, which is linked at the foot of the page. |
| 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. |
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 the Solest range is the same base oil at a range of viscosities and a wrong one 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 grade and only need a price, send the quantity and the destination port and we will quote directly.

The test method column is reproduced from the manufacturer's data sheet. Where the manufacturer publishes a value under a specific ASTM method, the method is shown so the figure can be traced to the published test rather than treated as a general property. The grade carries no ISO VG class number because 127.7 cSt at 40 °C falls between the ISO VG 100 band and the ISO VG 150 band; the classification and its bands are defined in ISO 3448.
A specification table says what the oil is; these are the figures that decide whether it suits a given circuit, read from the published values above rather than from our own measurement.
| Parameter | Value for Solest 120 | What it controls |
|---|---|---|
| Kinematic viscosity at 40 °C | 127.7 cSt — between the ISO VG 100 band (90–110 cSt) and the ISO VG 150 band (135–165 cSt) | The film thickness in the bearings, the seals and the rotor gaps, and the load the oil places on the compressor. This is the figure a replacement has to match, and on this grade it is the only figure that identifies the product — there is no ISO VG class number to quote instead. |
| Viscosity at 100 °C | 12.7 cSt | How much the film thins at operating temperature. The smaller the drop from the 40 °C value, the higher the viscosity index, and 90 is what fixes that relationship here. |
| Pour point | −27 °C | The cold end of the working window. Below this the oil stops flowing, so it is the figure that decides whether the grade suits a low-temperature circuit. |
| Flash point | 251 °C | The hot end of the working window and a rough measure of how the oil behaves at the discharge valve. |
| Water content | <50 ppm | How dry the oil is as supplied. A polyol ester absorbs moisture in service, so the as-supplied figure is the baseline the system has to stay near. |
The Solest range is one base oil offered across a range of viscosities, so the grades differ in thickness and in the duty they are intended for rather than in chemistry. Several of the heavier grades carry no ISO VG class number, so they are compared on the measured viscosity. The table shows the range as the manufacturer publishes it, with this product marked.
| Grade | Viscosity at 40 °C (cSt) | Viscosity index | Where it is used |
|---|---|---|---|
| Solest 22 | POE (synthetic) | Recip. / Rotary / Centr. / Recip. / Screw / Scroll | The lightest grade in the range |
| Solest 31-HE | POE (synthetic) | Recip. / Rotary / Centr. / Recip. / Screw / Scroll | High-efficiency version of the light grade |
| Solest LT-32 | POE (synthetic) | Recip. / Rotary / Centr. / Recip. / Screw / Scroll | The ISO VG 32 grade, for commercial and industrial refrigeration and air-conditioning compressors |
| Solest 46 | POE (synthetic) | Recip. / Rotary / Centr. / Recip. / Screw / Scroll | The mid-range grade |
| Solest 68 | POE (synthetic) | Recip. / Rotary / Centr. / Recip. / Screw / Scroll | A widely used mid-range grade |
| Solest 120 (this product) | POE (synthetic) | Recip. / Screw / Scroll | The lighter of the high-viscosity grades |
| Solest 170 | POE (synthetic) | Screw / Scroll | High-viscosity grade for screw and scroll compressors |
| Solest 180 | POE (synthetic) | Screw / Scroll | High-viscosity grade for screw and scroll compressors |
| Solest 220 | POE (synthetic) | Screw / Scroll | Higher-viscosity grade for heavier-duty plant |
| Solest 370 | POE (synthetic) | Screw / Scroll | The highest-viscosity grade in the range |
The manufacturer lists the same refrigerant family for every grade in the range; the grades are separated by the working viscosity and the compressor duty. Grades are shown as the manufacturer names them.
If this grade is not the one you need, the sections below show where it sits against the rest of the Solest range and against the oils we manufacture ourselves, so a substitution can be checked before it is ordered.
| Brand | Grade | Viscosity at 40 °C | Note |
|---|---|---|---|
| Qishanr | POE refrigeration oil | 127.7 cSt, our own grade at the same measured viscosity | Our own equivalent at this viscosity, blended in Foshan, China; our published grades either side of it are QSL-100H at 96 cSt and QSL-170H at 170 cSt |
| Lubrizol / CPI | Solest range | 22 to 370 cSt | The full polyol ester line from the same manufacturer, for HFC, HCFC and HFO duty; Solest 120 is the lighter of the high-viscosity grades within it |
| Lubrizol / CPI | Solest 170 | 175.2 cSt | The next grade up, in the same range and the same base oil |
A polyol ester and a mineral oil are not interchangeable even at the same viscosity. Match the base oil type to the refrigerant before matching the viscosity.
Solest 120 is a synthetic polyol ester (POE) with a kinematic viscosity of 127.7 cSt at 40 °C, and the Solest range is described by its manufacturer as designed for commercial and industrial refrigeration and air-conditioning compressors. A large refrigeration compressor loads its oil in three 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 separator relies on the oil not vaporising into the discharge gas.
The manufacturer's own description of the range follows those points. It cites greater film strength and bearing protection than standard HFC lubricants, outstanding miscibility — the property that lets the oil return to the compressor from the evaporator rather than collect there — and thermal stability confirmed by sealed-tube testing. That is the mechanical reason an ester is specified for this class of machine rather than a mineral oil of the same measured viscosity.
The viscosity is chosen from the compressor duty, not from the drum size. The Solest range spans 22 to 370 cSt at 40 °C, and Solest 120 is the lighter of the high-viscosity grades of it. A heavier oil forms a thicker film in the bearings and carries more load, and a lighter oil returns to the sump more readily at low temperature. Both directions have a cost when the grade does not match the machine: step up and the compressor works against a film it was not designed for, step down and the film thins under load.
The figure to work from is the compressor manufacturer's requirement, and the grade in the Solest range that matches it; that is the point at which we confirm the grade against the Lubrizol data before quoting.
Every number on this page is the manufacturer's published value for Solest 120, and where the manufacturer states a figure under a named test method the method is reproduced alongside it. That matters in a product category where values circulate between suppliers: the viscosity at 40 °C, the viscosity index, the pour point and the flash point are all reported against specific procedures, and a figure quoted without its method cannot be checked.
It also means a figure can be corrected against the source rather than repeated. Where the previously published version of this page carried a value that did not match the manufacturer's data sheet, the value on this page is the manufacturer's.
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 100 covers 90–110 cSt and ISO VG 150 covers 135–165 cSt, which are the two bands either side of this grade — and a fluid whose measured viscosity lands in the space between two bands belongs to neither of them. There is no ISO VG class for it, and none is created by writing one down.
This grade measures 127.7 cSt at 40 °C, which falls between the ISO VG 100 band and the ISO VG 150 band. The manufacturer designates it 120, and 120 is not one of the classes in ISO 3448 — the standard lists 100 and 150 as the steps either side of it. That is why no ISO VG number appears anywhere on this page, in the specification table, in the page title or in the schema markup: quoting one would be an assertion the standard does not support. What a buyer should match is the measured 40 °C viscosity, which is the figure the compressor manufacturer specifies and the figure the data sheet publishes.
The same is true at the heavy end of the range: Solest 120 at 127.7 cSt, Solest 170 at 175.2 cSt and Solest 370 at 393.1 cSt all fall between two ISO 3448 bands, while Solest 220 at 215.9 cSt falls inside the ISO VG 220 band and does carry a class number.
The Solest range is one base oil across a range of viscosities, so two grades that look almost identical on the drum can be wrong for each other's machine. A quotation that skips the grade 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 compressor or unit model, the refrigerant and the evaporating temperature, and we confirm the grade against the Lubrizol 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 polyol ester grade at this measured viscosity from our own line against the Lubrizol 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 compressor 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 states that the Solest range is available in a variety of packages, 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: Solest 120 is a synthetic polyol ester (POE) refrigeration compressor lubricant with a kinematic viscosity of 127.7 cSt at 40 °C. It is made by CPI Fluid Engineering, the compression and refrigeration fluids business of The Lubrizol Corporation, and the Solest range is described by its manufacturer as designed for commercial and industrial refrigeration and air-conditioning compressors running HFC, HCFC and HFO refrigerants. Its published data covers the viscosity, viscosity index, density, pour point, flash and fire points, dielectric strength and water content against named ASTM methods.
A: Both are polyol ester grades in the same Solest range but at different measured viscosities. Solest 120 measures 127.7 cSt at 40 °C, while Solest 68 measures 66.3 cSt. The manufacturer lists overlapping compressor types for the grades, so the two are not distinguished by compressor type alone, and neither is identified by an ISO VG class number. Send us the compressor model and the refrigerant and we will confirm which of the two matches the application.
A: The Solest range is an HFC, HCFC and HFO line, and the manufacturer describes the grades as designed to maximise lubrication in HFC systems with outstanding miscibility, so the oil and refrigerant mix and the lubricant can return to the compressor. For a mineral-oil system being converted, or for an application where the compressor manufacturer specifies a different chemistry, send us the gas and the compressor model and we will confirm which grade applies before quoting.
A: No. 127.7 cSt at 40 °C falls between the ISO VG 100 band and the ISO VG 150 band, and ISO 3448 defines a series of discrete bands rather than a continuous scale, so a viscosity that lands between two of them belongs to neither. The manufacturer designates this grade 120, and 120 is not one of the classes in ISO 3448 either. We do not quote a class number for it — a number the standard does not define would not help you compare oils, it would only look comparable. Match the measured 40 °C viscosity instead, which is the figure the compressor manufacturer specifies and the figure the data sheet publishes.
A: No. A polyol ester and a mineral oil are not interchangeable even at the same viscosity, and the two are not mixed in a working system. Where a machine is being changed from a mineral oil charge to a polyol ester, the changeover has to be carried out as a changeover rather than a top-up: the old charge is drained, the circuit is flushed and evacuated, and the moisture limit a polyol ester charge has to meet is confirmed before the new oil goes in. Confirm the changeover procedure with us before the system is charged.
A: The manufacturer publishes the pour point as −27 °C, measured by ASTM D97. The pour point is the cold end of the working window: below it the oil stops flowing, and a system running colder than that will starve the compressor of oil. It is a figure a buyer should compare against the system's evaporating temperature rather than against the ambient temperature, and on a large machine it is read together with the low-temperature miscibility of the oil in the refrigerant.
A: Each figure on this page is published by the manufacturer against a named ASTM procedure: ASTM D445 for the kinematic viscosity, ASTM D2270 for the viscosity index, ASTM D4052 for the density and specific gravity, ASTM D97 for the pour point, ASTM D92 for the flash and fire points, ASTM D877 for the dielectric strength, and ASTM D1533 for the water content. The method is shown so the figure can be traced to the published test rather than treated as a general property, and so two suppliers' data sheets can be compared on the same basis.
A: Yes. Private-label artwork and custom pack formats are a normal quotation item on our own equivalent grade, 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 polyol ester absorbs moisture from the air, and moisture is what shortens its service life: at high temperature, in the presence of the ester and the refrigerant, water promotes hydrolysis and the formation of acids. The container should be resealed after every use and the oil should not be decanted into an unlined steel drum where it can pick up rust and moisture.
Every figure on this page is taken from a published document rather than from our own measurement, so each one can be checked before you buy. This is the set of sources, with the document each figure came from.

| Lubrizol / CPI Fluid Engineering — Solest 120 refrigeration compressor lubricant technical data | The manufacturer's published data for this grade: the polyol ester base oil type, the HFC / HCFC / HFO application, the viscosity at 40 °C and 100 °C, the viscosity index, the density and specific gravity, pour point, flash and fire points, dielectric strength and water content, and the manufacturer's description of the base oil and the range. |

| ISO 3448:1992 — Industrial liquid lubricants — ISO viscosity classification | The standard that defines the discrete viscosity bands at 40 °C. It is the reason this grade carries no class number: 127.7 cSt falls between the ISO VG 100 band and the ISO VG 150 band, and the standard defines bands rather than a continuous scale. The band boundaries quoted on this page (90–110 and 135–165 cSt) come from that classification. |
Where a value is published by the manufacturer against a named test method, the method is reproduced with the figure so that the value can be traced to the published test.
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.
Solest 120 is a 127.7 cSt polyol ester, so a quotation depends on the grade, the pack size and the destination port rather than on a list price. Send your compressor or unit model, the refrigerant and the quantity you need. We will confirm the viscosity against the Lubrizol data — including whether your system takes the 127.7 cSt grade or the one next to it — 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 at the same measured viscosity side by side so the comparison is on landed cost.
