PACX Series Packaged Air Conditioners are self-contained, pre-assembled and pre-charged industrial quality

PACX Series Packaged Air Conditioners are self-contained, pre-assembled and pre-charged industrial quality units for use in areas classified as hazardous. A wide range of models meet the requirements of Articles 500 – 503 of the National Electrical Code (NEC) for equipment operated hazardous locations under Class I, Groups B, C, and D or Class II, Groups E, F, and G in Divisions 1 and 2. Every effort has been made to make PACX Series equipment safe, reliable and long lasting.

All units are easily field installed, requiring only minimal ductwork and a suitable power source. Models are offered in horizontal and downflow configurations for rooftop or ground level installation. When simultaneous building pressurization is required, PBX Series Combined Air Conditioning / Pressurization modules are recommended (**). A wide range of other options and accessories include steam or electric (Division 2 only) heaters, corrosion resistant epoxy finishes, SaveCoil 101 baked phenoxy coil coatings, head pressure controls, and particulate or gas phase air filter modules.
