RHT Series

RHT Series

Summit RHT series refrigeration compressor oils 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, and less oil make-up.

Recommended uses

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®).
