The RENISO S/SP series are fully synthetic, alkyl benzene 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. Very high thermal stability, excellent ageing and oxidation resistance, excellent low temperature behaviour, excellent oil-refrigerant solubility, good EP properties.
