Refrigeration is essential to human life, however the climate impact of the refrigerants and energy used is huge. Moving the refrigeration sector swiftly towards climate-friendly alternatives with high efficiency, is therefore essential.
Fortunately, numerous manufacturers and commercial and industrial operators have already successfully made this move and are safely and efficiently using HFC -free refrigerants in the refrigeration categories listed below.

The commercial refrigeration sector accounts for approximately 26 per cent of the heating, ventilation, air-conditioning and refrigeration (HVACR) sector’s total greenhouse gas emissions.


Industrial refrigeration provides cooling for large scale processes. Ammonia systems are a well established solution for industrial refrigeration due to their superior energy efficiency and ability to chill to very low temperatures.


The shift to Cool Technologies began in the domestic refrigeration sector when in 1992-93 Greenpeace developed and helped commercialise hydrocarbon refrigerators using isobutane as the refrigerant and cyclopentane as the insulation foam blowing agent.


The term ‘transport refrigeration’ covers several applications including refrigerated vans, refrigerated trucks and trailers and fishing vessels.
