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.

The ProtEX models have a 3 year warranty. We recommend that the product be replaced after 3 years because there is an internal part (a one-way valve on the hot exhaust) that has a limited life span. Failure or malfunction of this internal part will not affect the hazardous location rating of the product. However, after 3 years the part can lose its functionality and the cooling efficiency and sound level can deteriorate. Benefits
