Refrigerants

Linde offers a wide range of refrigerant products, including HCFCs, HFCs, HFOs and natural refrigerants, a full range of package sizes including cylinders, drums, and bulk deliveries. All cylinders are individually marked for traceability and may be combined with ACCURA® cylinder services as an advantage. Our range consists of the most widely used refrigerants and a selection is available from our sales outlets. Refrigerants such as ammonia (R717), carbon dioxide and non-halogenated hydrocarbons do not deplete the ozone layer and have no (ammonia) or only a low (carbon dioxide, hydrocarbons) global warming potential. They are used in air-conditioning systems for buildings, in sport and leisure facilities, in the chemical/pharmaceutical industry, in the automotive industry and above all in the food industry (production, storage, marine shipping, retailing).

One of the most promising alternatives is CO2 (R-744). Carbon dioxide is non-flammable, non-ozone depleting material. R-744 can be used as a working fluid in climate control systems for cars, residential air conditioning, hot water pumps, commercial refrigeration, and vending machines. R12 is compatible with mineral oil, while R134a is compatible with synthetic oil that contains esters. The R-# numbering system identifies systematically the molecular structure of refrigerants made with a single halogenated hydrocarbon. - The R-400 series is made up of zeotropic blends (those where the boiling point of constituent compounds differs enough to lead to changes in relative concentration because of fractional distillation) and the R-500 series is made up of so-called azeotropic blends. The rightmost digit is assigned arbitrarily by ASHRAE, an industry standards organization. - The R-700 series is made up of non-organic refrigerants, also designated by ASHRAE.
