Enclosure Coolers Earn UL Classification for Class I, II and III, Division 1 Locations
ProtEX Vortex A/C enclosure cooler was granted certification for Class I, Division 1, Groups A, B, C and D; Class II, Division 1, Groups F and G; and Class III. The 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. In addition, they are certified for ambient temperatures up to 175°F (79°C), which is greater than most hazardous-area-rated Freon air conditioners, says the manufacturer. The small enclosure coolers require minimal maintenance.
