RENISO SYNTH 68 is based on polyalphaolefins (PAO) with excellent chemical and thermal stability. It was developed especially for applications where ammonia is used as refrigerant. RENISO SYNTH 68 has a better lifetime compared to mineral oil-based refrigeration oils, lower evaporating losses due to the synthetic components and an excellent low temperature flowability. RENISO SYNTH 68 is recommended instead of mineral oil based or alkylbenzene-based products especially in highly stressed ammonia applications and/or for deep evaporating temperatures. RENISO SYNTH 68 can be used in piston as well as in oil-injected screw compressors.;RENISO SYNTH 68 is also especially suitable for applications with hydrocarbon refrigerants such as propane or propene.;RENISO SYNTH 68 can also be used in CO2 Systems (non-miscible with CO2).;RENISO SYNTH 68 is registered according to NSF H1 and fulfills and exceeds DIN 51503 KAA (non-miscible with ammonia), KB and KE.
