Genetron® 134a (1,1,1,2-tetrafluoroethane) is a non-ozonedepleting, environmentally safer refrigerant developed by Honeywell to replace CFCs and HCFCs in several air-conditioning and refrigeration applications. It possesses similar energy efficiency and capacity characteristics as CFC-12, has an intrinsically low toxicity, and is recognized as a superior long-term solution in many applications. This document is meant to provide engineers, technicians, and mechanics with basic Genetron 134a properties, plus application and handling information to facilitate safe and efficient usage. Applications Stationary Refrigeration and Air-Conditioning: Genetron 134a can be used in refrigeration applications including supermarket cases, walk-in coolers, beverage dispensers, vending machines, water coolers and home refrigerators. Genetron 134a is also used in centrifugal chillers. Genetron 134a is suitable for both new equipment and for retrofitting existing CFC-12 commercial refrigeration systems. Generally, there will be few equipment design changes necessary to optimize the performance of Genetron 134a in these applications. For further information on retrofitting, your Genetron refrigerants distributor or your Honeywell sales or technical representative can provide you with the most up-to-date retrofit literature. We also recommend consulting the original equipment manufacturer before performing any retrofit. Automotive Air-Conditioning: Several automobile and truck manufacturers have selected Genetron 134a for the initial charge in their new vehicles. Additionally, retrofit kits for converting CFC-12 systems to Genetron 134a are widely available. Honeywell is also proud to offer Genetron 134aUV, a special formulation of Genetron 134a and a refrigerant-soluble dye that fluoresces when exposed to ultraviolet light. Genetron 134aUV was developed specifically for automotive mechanics who wanted a solution for making leak detection in cars and trucks easier, faster, and less expensive. Aerosol and Foam-Blowing Applications: Genetron 134a is used as a propellant in many specialty aerosol products and may be used as a blowing agent for rigid-foam insulation. Additional information on the use of Genetron 134a in aerosol and foam applications is available through your Honeywell sales or technical representative.
