Summit RHT Series Refrigeration Lubricant

Summit

Summit RHT series are highly refined, hydrotreated ammonia compressor lubricants specially designed to function under the stringent requirements of closed-loop ammonia refrigeration systems. Besides providing value-added benefits in the areas of improved system efficiency and higher productivity, the performance advantages of Summit RHT series versus naphthenic oils include:

  • Reduced oil carryover
  • Superior cleanliness
  • Superior chemical and thermal stability
  • Enhanced wear protection
  • Lower foaming tendency
  • Extended oil drain interval capability
  • Less oil make-up
 

Summit RHT series are exceptionally well suited for rotary screw, reciprocating and rotary vane compressors in ammonia service.  They are compatible with naphthenic and other hydrotreated paraffinic-based compressor oils for ammonia service, as well as PAO and alkylbenzene-based products.  They are compatible with all seal elastomers commonly used in these systems including Buna-N, Neoprene and Fluorocarbon (Viton®).  Due to swelling, softening and rapid deterioration of Neoprene seals in the presence of naphthenic oils, it is strongly recommended that these seals be replaced before changing to Summit RHT.

Available as: RHT- 32, RHT- 46, RHT- 68, and RHT-100
