Make your refrigeration system more energy efficient and save money with R-Series

April 01, 2021

Keeping cool comes at a cost.  Specifically, the cost of electricity. In most cases, industrial refrigeration systems represent the largest single consumer of electricity within their respective facilities. Take, for example, cold-storage warehousing refrigeration systems. They can account for as much as 85- to 90-percent of overall facility energy requirements.

But there’s good news. Small changes, even the simple act of changing compressor oil, can contribute significantly to overall facility cost reduction.  Customers who upgrade facilities to Summit’s R-Series see energy savings of greater than 5% as compared with commonly used, traditional mineral oils. 

For example: A single ammonia screw compressor with a 410-brake horsepower requirement for a fixed-speed, fully loaded operation running year-round will cost about $195,000/annually – assuming the use of a 450 HP, 460/3/60 motor at a rate of $0.08/kWh.  For the purpose of this example, we’ll use a low-end savings estimate of 5%. A 5% savings equates to roughly $9,750/year savings on just one compressor when switching to the R-Series.    

Bottom line: The lubricant pays for itself within just a few months!

R-Series lubricants are a fully synthetic, PAO-based lubricant suited for both rotary screw and reciprocating compressors. They offer the following energy and cost savings benefits:

  • Increased Chemical Stability: Polyalpha olefin (PAO) based synthetic lubricants provide greater chemical stability than mineral oils. This means longer product life, less sludge formation, and a cleaner and more efficient system.
  • High Thermal Stability: High viscosity index (VI) values (greater than 135 across the entire R-Series) ensures maximum product life, provides proper lubricant film strength across a wide temperature range, and extends the life of the equipment.
  • Low Vapor Pressure = less oil carryover and reduction of labor / material cost due to extended oil drain / top-off intervals.

What’s even better: The R-Series is compatible with mineral oils, alkylbenzene-based oils, other PAO-based products, and all commonly used elastomers so you don’t have to fully drain the existing lubricant from the system.

Plus, it’s a NSF H1-registered, ISO 21469 food grade product that’s Kosher-approved and Halal certified.

ISO 9001

Summit first received its ISO 9001 certification in January of 1996, demonstrating a commitment to quality assurance and performance monitoring. ISO 9001 certification is an international quality standard that addresses a comprehensive list of business elements, including management responsibility, order processing, purchasing, process control, traceability, handling of non-conforming product, and internal auditing. Our present ISO 9001 certification is proof of our continuing quality commitment to our customers.


ISO 14001

Summit is committed to protecting the environment, the health and safety of our employees, customers and communities where we work and live. We recognize that through integrating sound environmental health, and safety management practices into all aspects of our business ... we can offer innovative products and services while conserving and enhancing resources for future generations.


NSF ISO 21469

ISO 21469 specifies hygiene requirements for the formulation, manufacture, use and handling of lubricants, which may come into contact with products during manufacturing or processing. The international standard applies to lubricants intended for use in food production, as well as cosmetic, pharmaceutical and animal feed industries. NSF ISO 21469 Certification by an independent, third party provides Summit with a means to obtain international acceptance for their products.
