3 -12.5 ton Air Conditioners with Automatic Building Pressurization

Industrial buildings in hazardous or dusty locations require pressurization to meet the requirements of NFPA 496, API, NEC, and other industrial codes.The PB 24 Series provides both air conditioning and pressurization with all necessary controls in one compact, pre-assembled and pretested module.

2 to 50 ton Air Conditioner, Pressurization and Optional Deep Bed Filter Module

PB 20 Series combines air conditioning, pressurization, and make-up air filtration on one skid. Units offer convenient and economic means for achieving compliance with NFPA 496 and similar industrial codes. A quiet, variable speed blower automatically maintains the preset building pressure. Only the make-up air required to offset building leakage and losses from door openings  is supplied. Gone are sluggish response, constant need for adjustments, and the high maintenance associated with barometric dampers. The units are fully instrumented with thermostat, pressure selector and display, and Start/Stop controls. Deep bed gas phase and high dirt loading filters are optional. Dual (redundant) blowers and air conditioning  with automatic switchover controls are optional.
