Businesses across North America are turning to EXAIR Corporation for reliable industrial cooling solutions, particularly in applications using compressed air. The company’s UL-classified Continuous Operation Hazardous Location NEMA 4X Cabinet Cooler Systems have become essential for maintaining optimal temperatures in control panels that require both constant cooling and positive purge protection. These specialized cooling units help protect sensitive electronics from heat, dust, and moisture in high-risk industrial environments while ensuring continuous operation.
EXAIR’s HazLoc cabinet coolers meet stringent UL safety requirements for use in classified hazardous areas, including Class I, Division 1 locations with flammable gases and vapors (Groups A, B, C, D), Class II, Division 1 areas with combustible dust (Groups E, F, G), and Class III environments with ignitable fibers. The systems utilize efficient vortex tube technology to deliver cooling capacities up to 5,600 Btu/hr without any moving parts, significantly reducing maintenance needs while providing reliable thermal management for purged electrical enclosures.
Available in eight different cooling capacities ranging from 1,000 to 5,600 Btu/hr, EXAIR’s cabinet coolers allow businesses to select the ideal system for their specific requirements without placing excessive demand on air compressors. The company’s thermostatically controlled models, which include UL-listed solenoids certified for hazardous locations, offer the highest level of energy efficiency for demanding industrial applications.
The NEMA 4X-rated systems provide robust protection against dust, oil, and water ingress, making them suitable for both indoor and outdoor installations. Each unit features a self-sealing relief valve that automatically closes when the cooler is inactive to maintain the integrity of the enclosure. Additional protective components include a water-dirt filter separator to prevent contaminants from entering the panel and a cold-air distribution kit that directs airflow precisely where it’s needed most.
In hazardous industrial environments where equipment failures can lead to costly downtime, EXAIR’s cabinet coolers play a critical role in preventing malfunctions caused by overheating. By maintaining stable operating temperatures, these systems help avoid sensor errors, control drift, and display inaccuracies that could otherwise require expensive component replacements or production shutdowns.
With their combination of safety certifications, durable construction, and efficient cooling performance, EXAIR’s HazLoc NEMA 4X Cabinet Cooler Systems provide industries with a trusted solution for protecting sensitive electronics in some of the most challenging working environments. The systems’ ability to prevent heat-related failures while requiring minimal maintenance makes them a cost-effective investment for businesses prioritizing operational reliability and safety.
