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. High viscosity index, good viscosity-temperature behaviour, extremely low pourpoint, high flashpoint, good lubricity.
RENISO SYNTH 68 is approved according to NSF H1 (USA 2005).
Recommended instead of mineral oil-based or alkylbenzene-based products especially in highly stressed ammonia applications and/or for deep evaporating temperatures.
