When hot weather causes the electronics inside a control cabinet to fail, there isa panic to get the machinery up and running again. The operator might chooseto simply open the panel door and aim a fan at the circuit boards. In reality,the fan ends up blowing a lot of hot, humid, dirty air at the electronics andthe cooling effect is minimal. If the machinery starts functioning again, thelikelihood of repeated failure is great since the environment is still hot (andthreatens permanent damage to the circuit boards). Worse yet, that openpanel door is an OSHA violation that presents a shock hazard to personnel.

“It took us three days to get a replacement computer cabinet and we didn’twant to risk another heat failure. Fans weren’t an option since they wouldjust blow around a lot of hot air. Freon-type air conditioners like those onsome of our other machines were a constant maintenance project of theirown. We purchased EXAIR’s Model 4330 NEMA 12 Cabinet CoolerSystem since it was easy to install and requires no maintenance.” @exair
DON’T DO THIS!
It is an OSHA violation that presentsa shock hazard to personnelThe fan blows hot, humid, dirty air atthe electronics.
BE AWARE OF CONDENSATION!
Refrigerant panel air conditioners causecondensation and moisture.
When condensation is present, electricalcomponents can begin to erode, resultingin severe damage.
A bad choice could cost you thousands!
