CXH Hazardous Location Unit Heater

Heat Exchanger

Efficient liquid-to-air design utilizes steel tubes, with integral rolled-aluminum fins. Industrial grade, seamless, Chromalox heating elements are immersed in a water glycol heat transfer fluid that provides freeze protection down to -40°F (-40°C) and can be operated in a maximum ambient of 104°F (40°C). A pressure relief device provides excess pressure protection and is factory helium leak tested to assure a leak-proof design. 7500' (2286 meters) Maximum Operational Altitude Above Sea level - Check with your Local Chromalox Sales Rep for higher altitude recommendations.
