Carbon dioxide offers a wealth of benefits when used as a natural refrigerant, says Ed Whinyates of Stonegrove Refrigeration.
In a period of massive change for ozone depleting HFC refrigerants, the impact is being felt within the perishable goods industry. As a designer and installer, we appreciate how this is impacting on refrigeration installations. Because of regulation on the ‘phasing out’ of certain refrigerants, it is important to work with customers to offer the best possible solution for their long term needs; this entails designing and installing plants with longevity. By moving away from environmentally harmful refrigerants towards installations using natural refrigerants - like ammonia (R717), propane (R290) and CO2 (R744) - we can future proof refrigeration equipment.
