SUNISO® SL

SUNISO SL 32

SUNISO SL 46

Overview

Suniso® SL oils are high-performance, synthetic refrigeration lubricants formulated for optimal performance of compressors using HFC and HFC / HFO refrigerant blends. Manufactured with specially engineered polyolesters (POE), Suniso SL lubricants ensure superior miscibility and efficient oil return throughout the system, from the evaporator to the compressor. In addition, Suniso SL lubricants retain viscosity very well with the refrigerant dissolved, offering maximum protection to compressor bearings. Suniso SL lubricants deliver exceptional thermal stability, making them suitable for applications ranging from low temperature refrigeration systems to high temperature heat pumps.

Features & 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.
  • Meets DIN 51503 KD and ISO6743-4 ISO-L-DRD specifications.
