RENISO UltraCool 68 is a synthetic hydrocarbon-based refrigeration oil for ammonia (NH3) refrigeration compressors. RENISO UltraCool 68 is a high-tech alternative to mineral oil based refrigeration oils. Synthetic components reduce the oil consumption due to less oil carry-over. This leads also to an increase of the system efficiency.RENISO UltraCool 68 improves the compressor efficiency due to excellent lubrication properties provided by higher viscosity over a wide temperature range. The good natural viscosity-temperature behaviour leads also to a higher wear protection when comparing RENISO UltraCool 68 with mineral oil based refrigeration oils.
RENISO UltraCool 68 was specifically designed for applications where ammonia is used as the refrigerant. Compatible with commonly used seal materials in NH3 refrigeration systems, e.g. chloroprene (CR).
