Protex Vortex AC

Model Numbers

ProtEX Vortex A/C Coolers are designed specifically for purged * Electrical enclosures in ATEX Zones 1 and 21, UL Class I, Div. 1 (Groups A,B,C and D), Class II, Div. 1 (Groups F and G), Class III and Temperature Class T3 areas. The ProtEX Vortex A/C incorporates the most up-to-date features into Vortec’s line of highly reliable, cost-effective enclosure coolers.

  • Sleek, modern design
  • Noise reduction of 78%, when compared to other vortex enclosure coolers
  • Energy use reduction through its integral mechanical thermostat
  • Filter contains pressure dop indicator notifying you of needed filter changes
  • Quick and easy installation in about 5 minutes
  • Flexible installation: top, side or front (door) mount
  • Incorporates check valve to prevent loss of enclosure pressure when cooling is not required
  • ATEX Certification Ex II 2 GD 
  • UL Classified Class I Div. 1, Class II Div. 1, Class III
  • Ex h llC T200C Gb
  • Ex h lllC T200°C Db
  • Ta+10 to +80C
  • T3 Temperature Class rating

The ProtEX Vortex A/C is available in 4 different cooling capacities; 900,1500,2500 and 5,000 BTU/hr. All of Vortec’s Enclosure Coolers keep Electrical and Electronic Enclosures cool, clean and protected and are a low cost alternative to expensive, high maintenance air conditioners; and avoid contamination with dirty, humid air caused by fans. Today’s small, compact multi-function electronic controls, variable speed drives, servos and programmable logic controllers are extremely sensitive to heat and contamination. Smaller cabinet sizes make temperature control difficult and prone to premature failures. Excessive heat will cause digital displays to misread, controls to drift, and breakers to trip below rated loads. The result is productivity lost due to machine or line shutdowns.

ProtEX Vortex A/Cs maintain a slight pressurization on the cabinet to keep electrical and electronic components clean and dry; and most are thermostatically controlled to maintain enclosure temperatures within a specified temperature range.
