Everest® lubricants are optimized for excellent miscibility and viscosity retention with HFC refrigerants like R-134a, R-410A, R-507, and R-404A. They are also compatible with low Global Warming Potential (GWP) transitional refrigerants such as R-1234yf, R-450A, and R-513A, and are well-suited for retrofitting R-22 systems with zero-Ozone Depletion Potential options like R-449A and R-448A.
Everest® ESR products for Sustainable Refrigerants
Everest® ESR (Enabling Sustainable Refrigeration) is LANXESS’ next generation refrigeration lubricants optimized specifically for select ultra-low GWP refrigerants such as R-290, R-744 and R-1234ze as well as low GWP transitional refrigerants such as R-32 and R-515B .
Hatcol® Esters drive the performance of our Everest® refrigeration lubricants
In synthetic ester refrigeration lubricants, performance is driven by the quality of the ester base stock. That’s why all Everest® refrigeration lubricants are formulated using Hatcol® polyol ester base stocks, renowned for their superior stability and performance. High-performance HFC and HCFC miscible systems require lubricants with excellent miscibility and long-term reliability. The use of advanced base stock technology is critical to ensure durability and efficiency in the field.
