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

June 08, 2021

Compressor lubrication provides essential support at the heart of closed-loop refrigeration systems.  Lubricant functions include:

  • Reducing friction of wear components to maximize component life
  • Removing waste heat generated during compression
  • Providing a fluid seal for rotor gaps
  • Inhibiting formation of rust and corrosion
  • Transferring particulate to strainers / filters to clean the system

For many years naphthenic lubricants were the preferred choice for refrigeration applications; however, these products are notorious for excessive oil carryover and sludge formation.  Today’s operational requirements call for advanced lubrication solutions designed to outperform the shortcomings of naphthenic products.

That's why Summit has spent years formulating the right refrigeration lubricant for the industry. The result is the RHT Series.

The RHT Series are highly refined, hydrotreated ammonia compressor lubricants. They outperform naphthenic oils by meeting the demands of closed-loop ammonia refrigeration systems.

Advantages 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

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

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.
