Vortex Enclosure Coolers Thermostat Controlled NEMA 12

Standard Vortex Enclosure Coolers are available in NEMA 12, NEMA 4, and NEMA 4X versions, and can be purchased with an electric thermostat or without a thermostat (constant run). The electrical cabinet cooling thermostat model maintains tight control on the temperature setpoint of +/- 3 degrees F. Vortex electric enclosure cooling systems are available in cooling capacities ranging from 400 BTU/hr to 5000 BTU/hr.

Enclosure Air 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.

Vortex Enclosure Coolers maintain a slight pressurization in 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.

Features

Small footprint to fit on all enclosures and in confined areas
Electrical thermostat models can be set to desired temperature +/- 3 deg F
Supplied with air filter and ducting kit
Maintains slight pressurization in the enclosure
