Packaged Air Conditioners with Room Pressurization/Filtration
Industrial Control Rooms, Analyzer Buildings, Motor Control Centers, and other installations in or near hazardous or dusty locations require both packaged air conditioning and pressurization. NFPA, API, and related industrial codes mandate both the building pressure and the airflow across a door or other openings that must be maintained. Pre-assembled and pretested PB(X) 20 systems provide these functions automatically. The control panel includes all controls for setting and monitoring room temperature, pressure, and pressure loss alarm. Models specified as “Explosion Proof” comply with Articles 500-503 of the National Electric Code (NEC) for Class I, Groups C and D or Class II, Groups F and G, Divisions 1 and/or 2.
A low noise, Vari-Speed blower automatically maintains the desired building pressure. The supply air can be limited to the amount required to offset air loss from the pressurized structure and from door openings. The results are lower heating and cooling requirements, substantial energy conservation, and lower operating costs. Gone are sluggish responses and the repeated need for adjustment and maintenance of damper-controlled designs.
Maximum make-up airflow can be specified in the range of 1300 to 6000 cu-ft per minute. The matched packaged airconditioning system operates in a recirculating mode. Ample external static pressures allow for any required distribution ducts. Cooling capacities range from 2 to 50 tons. The built-in housing will accept a wide variety of air filters for particulate or gas-phase corrosion and odor control media. Additional options are an audible pressure loss alarm, timer-controlled air purge, and gas detectors.

Explosion-Proof Packaged Air Conditioners
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 meets the requirements of Articles 500 – 503 of the National Electrical Code (NEC) for equipment operated in 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 packaged air conditioner 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.
