RENISO S/SP SERIES
Fully synthetic, alkylbenzene-based (AB) refrigeration oils for chlorine-containing refrigerants (RENISO S 68 also for NH3 applications)
Description
The RENISO S/SP series are fully synthetic, alkylbenzene-based refrigeration oils with anti-wear properties for chlorine-containing refrigerants. Sophisticated production processes ensure that the RENISO S/SP products are sulphur- and wax-free. RENISO S/SP products were developed for critical applications especially when good anti-wear properties are required. Compared to equiviscous, mineral oil-based refrigeration oils, the following wear protection values were established:
Four ball scar diameter (1 h at 150 N) RENISO SP 46: Mineral oil: 0.3 mm 0.6 mm
Almen-Wieland test RENISO SP 46 Mineral oil: 9000 N 1000 N
General Information
Because of its additivation the RENISO SP-series is not suitable for the use with ammonia. For NH3 applications we recommend RENISO S 68 which is free of additives.
Advantages
- Very high thermal stability
- Excellent ageing and oxidation resistance
- Excellent low-temperature behaviour (flocculation point with R22 < -60 °C)
- Excellent oil-refrigerant solubility (miscibility gap with R22 < -70 °C)
- Excellent wear protection
- Good extreme-pressure (EP/AW) properties
Application
RENISO SP products are recommended for use in
- R22 applications – low evaporating temperatures
- R22, R502 applications and with drop-in refrigerants i.e. R401A/B, R402A/B
- heat pumps used to heat tap water
- plants where very high compressor outlet temperatures are encountered.
- systems operating with R600a (iso-butane) and R290 (propane)
RENISO S 68 is particularly recommended for R717 (NH3) systems and for R22 applications.
In general, RENISO S/SP oils are recommended whenever other refrigeration oils provide insufficient protection against wear.
- RENISO S 68 – for NH3 and R22
- RENISO SP 32 / SP 46 / SP 100 / SP 220 – for R22
