Summit’s RHT Series - Keep Your System Running Clean and Efficient for Maximum Productivity

March 23, 2020

Recent uncertainties and reshaping of the world economies has reinforced the need for localized efforts to do more with less. As such it is increasingly important that all systems and operations run at top efficiencies with minimal maintenance downtime. 

For closed-loop refrigeration systems, maximizing efficiency begins at the heart of the system with proper compressor lubrication. Refrigeration lubricants are responsible for many functions, all of which ultimately contribute to overall operation efficiency, including: lubricating internal parts for wear protection, removing heat generated during compression, acting as a fluid seal, inhibiting rust and corrosion within the system, and cleaning the system. 

Although once widely popular, naphthenic refrigeration oils are prone to creating operational inefficiencies due to excessive oil carryover and sludge formation. Today’s operational requirements call for advanced lubrication solutions designed to outperform the shortcomings of naphthenic products.

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. Summit’s RHT Series lubricants offer superior resistance to thermal and chemical degradation to keep your refrigeration system running clean and at top efficiency.

RHT Series answers a lot of the shortcomings that naphthenic oils produce. The performance advantages of RHT Series lubricants 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 has spent years refining the formulations of our refrigeration lubricants to meet specific industry needs. Contact the experts at Summit on how to position your refrigeration system with a cleaner solution for improved efficiency and higher productivity with RHT Series lubricants.

Spend less time cleaning strainers, replacing filters and draining oil. Now is the right time to update and upgrade your refrigeration system to Summit RHT Series lubricants.


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.

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.
