Energol RC-R

 

Description

Air compressor lubricant

The Energol RC-R™ compressor oil range of lubricants are based upon highly refined mineral oils and carefully chosen additives. They are intended for the lubrication of rotary and reciprocating compressors.

 

Application

The Energol RC-R grades are ashless oils recommended for the lubrication of rotors, bearings and gears in rotary compressors, especially the oil flooded screw type. Energol RC-R can be used for either normal or severe duty lubrication of reciprocating and rotary drip-feed air compressors, as defined by ISO 6743. Energol RC-R compressor oils exhibit low carbon forming tendencies and meet the requirements of the DIN 51506 VDL classification for reciprocating compressors having air discharge temperatures up to 220°C. Selection of the required viscosity grade should be based upon the compressor manufacturers’ recommendation however as a general guide Energol RC-R 32 and 46 are suitable for oil flooded rotary compressors, whereas Energol RC-R 68 and 100 would be selected for lubricating the crankcase and cylinders of reciprocating compressors.

 

Energol RC-R 150 is recommended for sliding-vane compressors, or for reciprocating units at high ambient temperatures. The Energol RC-R range is fully compatible with nitrile, silicone and fluoropolymer seal materials.

 

Energol RC-R grades are classified as follows:

  • DIN 51506 classification – VDL
  • ISO 6743/4 – DAA and DAB for reciprocating air compressors, DAG for rotary air compressors. 

 

Advantages
 
  • Good water separation characteristics allow condensation residues to readily separate from the oil, minimising the risk of emulsions which could block the oil separator element.
  • Prevents corrosion when operating under humid conditions.
  • Excellent coalescing properties mean minimal carry over of oil in the air stream.
  • Low deposit forming tendencies extends oil change intervals and provides longer air filter life which contributes to a reduction in maintenance costs.
  • Good thermal stability, low volatility and low carbon formation reduces the risk of fire and explosion.
