CP-4700-32 is a synthetic alkylbenzene (AB) refrigeration oil with a kinematic viscosity of 30.60 cSt at 40 °C, which places it inside the ISO VG 32 band. It is part of the CP-4700 range made by CPI Fluid Engineering, the compression and refrigeration fluids business of The Lubrizol Corporation, and the manufacturer lists R22, R407C, R12 and R502, the refrigerants the manufacturer lists for the CP-4700 range.
We manufacture and supply this viscosity class ourselves, at our own blending plant in Foshan, China — our equivalent is our own alkylbenzene equivalent at this viscosity class. 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 operating temperature and we will confirm the grade against the CPI 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.
CP-4700-32 is supplied on published terms: the 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 CP-4700-32 |
|---|---|
| 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 level, not the annual capacity of the plant |
| Origin | The original Lubrizol CPI product, or an equivalent manufactured at our own plant in Foshan, China |
| Supply options | The original CPI CP-4700-32, or our own alkylbenzene equivalent at this viscosity class 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 operating temperature. The CP-4700 range is the same base oil at several viscosity levels, so we confirm that CP-4700-32 is the right one for your machine before quoting |
| Viscosity | 30.60 cSt at 40 °C, which falls inside the ISO VG 32 band (28.8–35.2 cSt) defined by ISO 3448 |
| Pack size | Confirmed at quotation. The manufacturer lists this grade in 5 gal (18.9 L) pails and 55 gal (208 L) drums; custom pack formats and private-label artwork 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. On an alkylbenzene charge the low-temperature behaviour is decided by what is in the oil, so cleanliness matters as much as the grade. 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.
| What you are dealing with | What we do about it |
|---|---|
| You cannot tell whether the system takes 30.60 cSt or the level next to it | Send the compressor model, the refrigerant and the operating temperatures. The CP-4700 range is the same base oil at several viscosities and the neighbouring grades are separated by the compressor duty and the working viscosity, so the answer comes from the data sheet rather than from the can. We confirm the grade in writing before you order, so it can be checked against the specification. |
| You have the CPI data sheet and need the grade to match it | We confirm the viscosity and the base oil type against the CPI 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. |
| You want the grade under your own label | Private-label artwork and custom pack formats are a normal quotation item. 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. |
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 CP-4700 range is the same base oil at a range of viscosities and a wrong class 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 values below are the manufacturer's published figures for CP-4700-32, taken from the CPI CP-4700 series technical data. Every figure is tied to the document it came from, which is linked at the end of the page.
| Property | Typical Value | Test Method | Source |
|---|---|---|---|
| Oil type | Synthetic alkylbenzene (AB) | — | CPI — CP-4700 series technical data |
| ISO viscosity grade | ISO VG 32 (ISO 3448) | — | Derived — 30.60 cSt falls inside the 28.8–35.2 cSt band |
| Kinematic viscosity at 40 °C | 30.60 cSt | ASTM D445 | CPI — CP-4700 series technical data |
| Kinematic viscosity at 100 °C | 4.46 cSt | ASTM D445 | CPI — CP-4700 series technical data |
| Viscosity index | 10 | ASTM D2270 | CPI — CP-4700 series technical data |
| Density at 60 °F | 7.17 lb/gal | ASTM D1298 | CPI — CP-4700 series technical data |
| Specific gravity | 0.86 | ASTM D1298 | CPI — CP-4700 series technical data |
| Pour point | −45 °C (−49 °F) | ASTM D97 | CPI — CP-4700 series technical data |
| Flash point | 182 °C | ASTM D92 | CPI — CP-4700 series technical data |
| Fire point | 190 °C | ASTM D92 | CPI — CP-4700 series technical data |
| Floc point | −65 °C max | ANSI/ASHRAE 86 | CPI — CP-4700 series technical data |
| Refrigerant | R22, R407C, R12 and R502 | — | CPI — CP-4700 series technical data |
Every figure in this table is reproduced from the CP-4700 series technical data sheet, which prints the value against a named ASTM or ANSI/ASHRAE method. The floc point method is printed there as "ASTM ASH86"; the standard it refers to is ANSI/ASHRAE 86, Methods of Testing the Floc Point of Refrigeration-Grade Oils, and it is written here under that designation.
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.
| Parameter | Value for CP-4700-32 | What it controls |
|---|---|---|
| Kinematic viscosity at 40 °C | 30.60 cSt — inside the ISO VG 32 band of 28.8–35.2 cSt | The film thickness in the bearings and the load the oil places on the compressor. This is the figure a replacement has to match. |
| Viscosity index | 10 | How steeply the oil thins as it heats up. A low index means the viscosity falls more quickly with temperature than it would for a high-index synthetic, and on this grade the index describes the base oil rather than setting a target: an alkylbenzene is chosen for its miscibility and its floc point. |
| Pour point | −45 °C (−49 °F) | 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. |
| Floc point | −65 °C max | The highest temperature at which wax or other solid substances may precipitate out of the oil-and-refrigerant mixture, measured under ANSI/ASHRAE 86. The limit is a maximum, so a lower figure is the better one. This is the figure that decides whether the expansion device can block with wax at low temperature, and it is read together with the pour point rather than instead of it. |
| Flash point | 182 °C | The hot end of the working window and a rough measure of how the oil behaves at the discharge valve. |
The CP-4700 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. The table shows the grades we publish for this range, with this product marked.
| Grade | Oil type | Viscosity at 40 °C | Where it is used |
|---|---|---|---|
| CP-4700-32 (this product) | Alkylbenzene | 30.60 cSt | The lightest grade we list in this range, at 30.60 cSt |
| CP-4700-68 | Alkylbenzene | 56.04 cSt | The mid-range grade, at 56.04 cSt — no single ISO VG class covers it |
The manufacturer lists the same refrigerant and application for every grade in the range; the grades are separated by the viscosity and the compressor duty.
If this grade is not the one you need, the table shows where it sits against the rest of the CP-4700 range and against the other CPI lines we publish, so a substitution can be checked before it is ordered.
| Brand | Range | Viscosity at 40 °C | Note |
|---|---|---|---|
| Qishanr | Alkylbenzene refrigeration oil | 30.60 cSt, our own Alkylbenzene grade | Our own equivalent at this viscosity and base oil type, blended in Foshan, China |
| Lubrizol / CPI | CP-4700-100 | 95.18 cSt | The heaviest grade in the same alkylbenzene range |
| Lubrizol / CPI | Solest range | 22 to 370 cSt | The polyol ester line from the same manufacturer, for HFC and HFO duty — a different base oil type, so not a substitute for this grade |
Two oils with the same viscosity are not interchangeable if the base oil type differs. Match the base oil type to the refrigerant first, then the viscosity to the compressor.
An alkylbenzene is a synthetic base oil that sits between a mineral oil and a polyol ester, and the property that decides where it is used is miscibility with mineral oil. The manufacturer describes the CP-4700 range as fully miscible with mineral oil, which is why the grade can be added to a mineral oil system rather than only used as a complete replacement charge. A polyol ester cannot: it is the base oil for HFC and HFO duty, where mineral oil does not mix with the refrigerant at all, and it is not blended into a mineral charge.
The other half of the case is the floc point. On a mineral or alkylbenzene charge the low-temperature limit is not set by the pour point alone, because wax can come out of the oil-and-refrigerant mixture well before the oil itself stops flowing. An alkylbenzene is chosen for a low floc point, and the manufacturer publishes that limit for every grade in this range.
The viscosity is chosen from the compressor duty, not from the drum size. The CP-4700 range runs from 30.60 cSt to 56.04 cSt at 40 °C, with CP-4700-68 at 56.04 cSt above this grade. A heavier oil forms a thicker film in the bearings and the rotor gaps and carries more load; a lighter oil returns to the sump more readily at low temperature. Both directions have a cost when the class 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 CP-4700 range that matches it. That is the point at which we confirm the grade against the CPI data before quoting.
Wax precipitation is what blocks an expansion device, and it happens at a temperature the pour point does not describe. The floc point is the highest temperature at which wax or other solid substances may precipitate out of the oil-and-refrigerant mixture under the standard test, so it is a ceiling rather than a floor and a lower figure is the better one. The manufacturer publishes it for every grade in the CP-4700 range, measured under the floc point procedure.
The two figures are read together: the pour point describes when the oil in the sump stops moving, and the floc point describes when wax starts to come out of the mixture in the circuit. A grade can have a good pour point and still wax up at the expansion valve. Send the evaporating temperature and the refrigerant and we will confirm the grade against that pair of figures rather than against the viscosity alone.
The CP-4700 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 operating temperature, and we confirm the class against the CPI 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 our own alkylbenzene equivalent at this viscosity class against the CPI 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 lists this grade in 5 gal (18.9 L) pails and 55 gal (208 L) drums, 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: CP-4700-32 is a synthetic alkylbenzene (AB) refrigeration oil with a kinematic viscosity of 30.60 cSt at 40 °C, which places it in the ISO VG 32 class. It is made by CPI Fluid Engineering, the compression and refrigeration fluids business of The Lubrizol Corporation, and the manufacturer lists R22, R407C, R12 and R502, the refrigerants the manufacturer lists for the CP-4700 range.
A: The manufacturer lists R22, R407C, R12 and R502, the refrigerants the manufacturer lists for the CP-4700 range. That mix is worth reading carefully: it covers an HCFC (R22), a zeotropic HFC blend (R407C) and two CFCs (R12 and R502), which is the footprint an alkylbenzene charge is chosen for. For an HFC refrigerant outside R407C, such as R-134a, R-404A or R-410A, a polyol ester grade is the one to look at. For a refrigerant outside that list, send us the gas and we will confirm which range applies before quoting.
A: They are the same base oil at two different viscosity levels. CP-4700-32 measures 30.60 cSt at 40 °C and CP-4700-68 measures 56.04 cSt, so the difference is the film thickness the oil forms in the bearings and the load it places on the compressor. They are not interchangeable on a machine that was specified for one of them; match the class to the compressor duty and the refrigerant.
A: Yes. The manufacturer describes the CP-4700 range as fully miscible with mineral oil, which is why the grade can be added to a mineral oil system rather than only used as a complete replacement charge. That is the practical difference between this grade and a polyol ester, which is not blended into a mineral charge. If you are topping up, tell us the oil that is already in the system and the refrigerant, and we will confirm this grade against it before you order.
A: The manufacturer publishes the floc point as −65 °C maximum. It is the highest temperature at which wax or other solid substances may precipitate out of the oil-and-refrigerant mixture under the standard test, so it is a ceiling and a lower figure is the better one. On a mineral or alkylbenzene charge that is the figure that decides whether the expansion device can block with wax, and it is read together with the pour point rather than instead of it.
A: The technical data sheet and the safety data sheet come with the quotation, and a certificate of analysis for the delivered batch comes with the shipment. CE, CO and transport certification are issued as standard export documents when the destination requires them — tell us at the enquiry stage which certificate the destination asks for and we compile the file with the quotation rather than after the shipment.
A: Each figure on this page is published against a named procedure: ASTM D445 for the kinematic viscosity, ASTM D2270 for the viscosity index, ASTM D1298 for the density and specific gravity, ASTM D97 for the pour point and ASTM D92 for the flash and fire points, with ANSI/ASHRAE 86 for the floc point. 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. Contamination stays in the sump rather than being filtered out on a charge that stands for long periods, so the container should be resealed after every use and the oil should not be decanted into an unlined steel drum.
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.
| Source | What it establishes |
|---|---|
| CPI — CP-4700 series technical data | The figures in the specification table: the viscosity at 40 °C and 100 °C, the viscosity index, the density, the specific gravity, the pour point, the flash and fire points and the floc point for CP-4700-32. |
| ISO 3448:1992 — Industrial liquid lubricants — ISO viscosity classification | The standard that defines the viscosity bands used to place 30.60 cSt at 40 °C inside the ISO VG 32 class. The band boundaries quoted on this page come from that classification. |
| The Lubrizol Corporation — compression, refrigeration and thermal fluids | The manufacturer's own description of the business and product lines that the CP-4700 range belongs to, used for the statements on this page about who makes the product. |
| ASTM D445 — Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids | The procedure behind the viscosity figures at 40 °C and 100 °C. |
| ASTM D97 — Standard Test Method for Pour Point of Petroleum Products | The procedure behind the pour point figure. |
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.
CP-4700-32 is a 30.60 cSt Alkylbenzene grade, 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 CPI data — including whether your system takes the 30.60 cSt grade or the level 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 viscosity side by side so the comparison is on landed cost.
