RHT Series

Summit RHT Series Performance Plus oils are a highly refined, hydrotreated ammonia compressor lubricants, specially designed to function under the stringent requirements of closed-loop ammonia refrigeration systems. Besides providing valueadded benefits in the areas of improved system efficiency and higher productivity, the performance advantages of Summit RHT Series oils 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.
