When used in conjunction with a purge/pressurization system, the Hazardous Location Duty (HazLoc) Vortex A/C provides essential enclosure cooling protection. When not operating in a cooling mode (when the unit’s integrated mechanical thermostat senses acceptable enclosure temperatures), the purge system creates positive pressure in the enclosure. This occurs as the HazLoc Vortex A/C’s integrated check valve seals off the cold air outlet, thus allowing the purge system to maintain the requisite pressure to block gases, vapors, dusts, fibers and contaminants from penetrating the enclosure.
The HazLoc Vortex A/C is specifically designed for simple installation and flexible mounting. Neither its mounting position or cold air ducting is limited by the check valve’s design.
