Refrigeration compressors
Synthetic lubricants are tailored to fit the needs of refrigerants by being optimally
miscible with the gas whilst providing lubrication in the hot region of the compressor
and still being suitably fluid to pass through the cold region of the evaporator.
ENERSYN LPS 46, LPS 68 and LPS 100
ENERSYN LPS, previously marketed under the ENERGOL trademark, is an alkyl benzene based synthetic lubricant which has particular physical and chemical properties that are highly suited to modern reciprocating refrigeration compressor equipment.
Performance features:
- suitable for use with R 22 and R 502 refrigerants but not HFC’s
- superior to conventional mineral oils especially at very low evaporation temperatures
- low refrigerant gas miscibility thereby maintaining effective lubrication
- excellent chemical stability
ENERSYN LPS meets the requirements of the major compressor manufacturers.
ENERSYN LPS-PO 68 and LPS-PO 220
ENERSYN LPS-PO is a polyalphaolefin based lubricant for use in mini-rotaryscrew refrigeration compressors which require a lubricant with a wide operating temperature range. It is for use with all refrigeration gases with the exception of hydroflurocarbons (HFCs) and sulphur dioxide.
Benefits:
- good thermal and chemical stability which gives long life under severe service conditions
- low-wear characteristics
- wax-free/low pour point
- wide operating temperature range
ENERSYN LPS-PO 68 has been designed to fully meet the Stal requirement where
‘Oil Type B’ is specified, whereas ENERSYN LPS-PO 220 is formulated to meet the
specification for ‘Oil Type C’.
ENERSYN MP-S 32, MP-S 46, MP-S 68, MP-S 100, MP-S 170 and MP-S 220
Enersyn MP-S is a range of polyolester based synthetic lubricants, designed for refrigeration compressors where HFC refrigerants e.g. R-134A, R404A, R407C, R410A and R507. It has been developed following the Montreal Protocol in 1987, where it was agreed that the production and use of gases causing depletion of the ozone layer would be phased out. Most marine refrigerants use CFCs and HCFCs, both of which cause ozone layer destruction.HFCs are an ‘ozone-friendly’ alternative to CFCs but unfortunately they are not miscible with mineral oils which have been used for many years in refrigeration systems. MP-S has been developed as a synthetic lubricant that can be used with HFCs.
Performance features:
- its miscibility with the HFC refrigerants
- good thermal oxidative stability
- antiwear characteristics
MP-S has been approved by and/or meets the requirements of the major
refrigeration compressor manufacturers.
