Suniso Polyolester oil SL220

Description

Very high viscosity for specific industrial or screw compressors.

• Superior Miscibility: As a POE oil, it has exceptional miscibility (ability to mix) with HFC refrigerants, which is crucial for ensuring efficient oil return from the evaporator back to the compressor, thereby preventing system damage and maintaining efficiency.
• High Thermal Stability: This makes it suitable for a wide range of applications, from low-temperature refrigeration systems to high-temperature heat pumps, preventing oil degradation and sludge formation.
• Optimal Viscosity Retention: The formulation is balanced to prevent excessive viscosity reduction when the refrigerant dissolves into the oil. This maintains a protective lubricating film to prevent friction and wear on compressor bearings and moving parts.
• Cleaner Operation: It is designed to run cleanly, leading to fewer deposits and reducing failures due to issues like valve sticking.
• Low Temperature Performance: The synthetic base stock ensures excellent performance at low temperatures.
• Hygroscopic Nature (Important Note): Like all POE oils, the Suniso SL series is highly hygroscopic (it readily absorbs moisture from the air). This means it must be handled carefully, and cans should be sealed quickly after use to prevent moisture contamination, which can lead to acid formation in the system.
