ITW Vortec has updated its line of enclosure coolers. The ProtEX Vortex A/C enclosure cooler has been granted certification for Class I, Division 1, Groups A, B, C and D; Class II, Division 1, Groups F and G; and Class III, after review by UL. The new UL Classification is on top of the existing ATEX Certification for Zones 1 and 21, which complies with the latest EN ISO 80079 36:2016 standard. The combination of UL Classification and ATEX Certification expands the industries and locations where Vortec enclosure coolers can be used. According to the company, ATEX and UL Certifications mean that industrial facilities can now save thousands of dollars while cooling electrical, electronic, and control system enclosures in ATEX Zones 1 and 21, as well as Class I, II and III Division 1 locations. In addition, they are certified for ambient temperatures up to 175°F. These Vortec models offer 900, 1,500, 2,500 or 5,000 Btuh cooling capacity.
