Building blocks for sustainable refrigeration highlighted at Inter Lubric, Shanghai

Perstorp is increasing its efforts to support a more environmentally friendly refrigeration industry. The company’s polyols and acids are a key components of polyol ester (POE) refrigeration oils, which play a vital role in sustainable, energy-efficient systems using the latest refrigerants.
Every day, the cooling industry enables millions of people all over the world to enjoy fresh food and air-conditioned homes and offices. The industry is growing quickly and has a significant impact on climate change. The need for sustainability is therefore increasingly urgent. This is an area where refrigeration oils, known as Reflubes, can play a vital role.
Reflubes typically consist of a base oil plus additives that fine-tune functionality. “The choice of base oil is strategic,” notes Jenny Klevås, Marketing Manager at Perstorp. She points out that studies have shown polyol esters (POEs) to have the versatility that the new refrigerants demand.
POEs have advantages over other base oil formulations in many areas, including viscosity, volatility, lubricity, compatibility and high- and low-temperature performance. “POEs have clear benefits in systems using HFCs, HFO and HFO/HFC blends,” she says, “and they are easy to blend with the vital additives.”
Perstorp is now focusing a range of activities to support the transformation to more efficient and sustainable refrigeration. This includes the development of the polyols that are a key building block of POEs. The company’s portfolio includes both traditional and innovative pro-environment polyols, as well as the acids needed to esterify them.
“Our building blocks may be microscopic, but their potential impact is on a planetary scale,” says Jenny.
Perstorp will be attending Inter Lubric, the China International Lubricants and Technology Exhibition (Shanghai, 7-9 Nov 2018, www.interlubric.com/en). Skilled sales managers will be available to discuss polyols and their applications in refrigeration systems.
