Description
Introduction
- The Suniso SL range is a high-performance synthetic refrigeration fluid for compressors using HFC refrigerants.
- It is made with specially engineered polyol esters (POE) for strong miscibility and efficient oil return.
- The fluid keeps its viscosity even when mixed with refrigerant, protecting compressor bearings.
- Suniso SL fluids offer excellent thermal stability for both low-temperature refrigeration and high-temperature heat pumps.
Benefits
- MISCIBILITY WITH HFC REFRIGERANTS: Promotes efficient oil return from evaporator to compressor, thereby preventing oil buildup in the evaporator and other system components, minimizing the risk of reduced system efficiency and damage.
- OPTIMAL VISCOSITY RETENTION: Balanced formulation avoids excessive viscosity reduction due to the dilution of the lubricant by the refrigerant. This helps maintain a protective lubricating film across a wide temperature range, reducing friction and preventing metal-to-metal contact.
- HIGH THERMAL STABILITY: Suitable for a wide range of applications ranging from low temperature refrigeration systems to high temperature heat pumps
Applications
- Suniso SL range lubricants are recommended for use in refrigeration, air-conditioning and heat pump systems utilizing ozone friendly, chlorine-free refrigerants.
- Compatible with all HFC refrigerants (e.g. R-125, R-134a, R-143a, R-152a, R-404A, R-407C, R-410A and R-507A)
- Suniso SL fluids exhibit exceptional miscibility even at extremely low temperatures.
- They are suitable for a wide range of compressor types, including reciprocating, screw, centrifugal, and scroll compressors found in applications such as petrochemical, cold storage, trucking, supermarkets and home air-conditioning systems.
