FUCHS RENISO MS 46 is an ISO VG 46 refrigeration compressor oil based on an alkylbenzene and naphthenic mineral-oil formulation. It is specified for older CFC/HCFC compressor service, including R22, R502, R401A/B and R402A/B applications.
Buyers sourcing FUCHS RENISO MS 46 refrigeration oil for service stock get a defined ISO VG 46 option for legacy and transition-refrigerant refrigeration systems. This RENISO MS 46 compressor oil combines alkylbenzene refrigerant solubility with an anti-wear package for compressors operating under demanding temperature and load conditions.
For freezer rooms and low-temperature storage systems running R22 or R502, RENISO MS 46 supports the oil requirement recorded for the compressor during planned maintenance and oil changes.
Suitable for service stock used on documented CFC/HCFC commercial refrigeration equipment, from condensing units to walk-in cold-room compressor circuits.
Designed for plant-maintenance work where heavily loaded refrigeration compressors need an alkylbenzene refrigeration oil at ISO VG 46.
For R401A/B and R402A/B equipment, RENISO MS 46 gives maintenance teams a product to request when the refrigeration-service record specifies this oil family and grade.
Maintenance-ready quotation: include the compressor model, refrigerant, required quantity and destination with your inquiry so the package can be matched to the planned service work.
| Property | Reference Value | Why It Matters |
|---|---|---|
| Lubricant type | Alkylbenzene / naphthenic mineral-oil formulation | Designed for CFC/HCFC compressor service with an anti-wear additive system. |
| Viscosity grade | ISO VG 46 | Matches maintenance specifications that call for a VG 46 refrigeration compressor oil. |
| Kinematic viscosity at 40°C | 46 mm2/s | Reference viscosity at the standard comparison temperature. |
| Pour point | -42°C | Relevant to low-temperature refrigeration service. |
| System or Refrigerant | RENISO MS 46 Position | Typical Maintenance Context |
|---|---|---|
| R22 | Listed application | Legacy commercial, industrial and cold-room compressor service when this oil is specified. |
| R502 | Listed application | Low-temperature refrigeration equipment that specifies an ISO VG 46 AB/naphthenic refrigeration oil. |
| R401A / R401B | Listed transition-refrigerant application | Service and maintenance for chlorine-containing drop-in refrigerant systems. |
| R402A / R402B | Listed transition-refrigerant application | Compressor lubrication for documented conversion and maintenance work. |
When a technician is servicing an older R22 condensing unit, the key purchasing question is whether the service record calls for an ISO VG 46 alkylbenzene refrigeration oil. RENISO MS 46 is a practical R22 compressor oil to quote when that specification is present.
The 20 L metal can shown in the product image suits contractors planning several compressor jobs or a scheduled cold-room shutdown. State the number of circuits and planned charge quantity in the inquiry for pack planning.
For R401 or R402 systems, maintenance teams often need the oil specification recorded alongside the refrigerant conversion. RENISO MS 46 is designed for the R401A/B and R402A/B application set.
Plant buyers can request a quotation with the compressor brand and model, refrigerant, package requirement, quantity and destination to align product supply with the shutdown schedule.

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.
