Germany’s LANXESS has made headlines with the launch of Everest ESR 220, a cutting-edge synthetic ester lubricant tailored for HVAC and refrigeration systems utilizing the low-GWP refrigerant R-1234ze. This innovative product, developed in conjunction with a distinguished OEM, promises enhanced performance in screw compressors, prioritizing both stability and sustainability. Additionally, Everest ESR 220 is compatible with R-515B and aligns with LANXESS’ ambitious climate-neutral objectives set for 2040.
As the industry pivots from high Global Warming Potential (GWP) hydrofluorocarbon (HFC) refrigerants like R-134a to more sustainable alternatives, LANXESS is stepping up as a leader in synthetic lubricant technology. The patented Everest ESR 220 addresses crucial requirements for a lubricant that pairs efficiently with R-1234ze, particularly in screw compressors, where conventional synthetic oils fall short.
LANXESS points out that refrigeration lubricants operate in a unique environment, as they are always blended with refrigerants. Effective compatibility is essential for the systems to function reliably. Many commercial lubricants previously used with HFC refrigerants have been found ineffective with R-1234ze. Ed Hessell, a technology manager at LANXESS, highlighted the company’s commitment to providing solutions that enable new applications, such as large-scale district heat transfer.
Everest ESR 220 is designed to deliver exceptional efficiency in refrigeration systems. It boasts numerous benefits, which include:
- Optimized compatibility with R-1234ze, ensuring seamless integration in significant cooling and heating applications across industrial processes, large-scale buildings, and data centers.
- Superior stability, attributed to synthetic esters, which leads to reduced maintenance and prolonged service life for refrigeration systems.
- Formulation aimed at minimizing friction and wear in compressors, resulting in lower operational costs and a reduced carbon footprint.
- Enhanced sustainability, earning LANXESS’ sustainable Scopeblue label, governing its commitment to achieve climate neutrality by 2040.
Screw compressors, known for their versatility in various commercial and industrial applications, find use in HVAC systems for buildings, manufacturing process cooling, and industrial refrigeration. They are also primed for growth in industrial heat pumps, a market projected to expand at over 15 percent per annum until 2030, according to a recent McKinsey report.
LANXESS is effectively leading the charge in synthetic lubricant innovation, ensuring that the transition to low-GWP refrigerants doesn’t compromise performance while promoting sustainability across the refrigeration landscape.
