Summit RHT-100 Refrigeration Lubricant for Closed Loop Ammonia Systems, ISO 100, NSF H2-Registered

Summit RHT-100 is a highly refined ISO 100 hydrotreated ammonia compressor lubricant, 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, ther performance advantages of Summit RHT-100 oil versus naphthenic oils include:

  • Lower wax content versus the “essentially” or “virtually” wax free oils marketed by competitors
  • 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 Performance Plus oils are exceptionally well suited for rotary screw and  reciprocating 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, NBR and Neoprene.
