A mining company has processing machinery operating in a poorly ventilated, dusty environment (actually, it’s a mine…as you might have guessed.) This machine’s control panel was supplied with filtered vents and fans to cool the electronic components inside. The filters clog regularly, and even though they checked them frequently, it’s not always frequently enough to prevent the drive from overheating.
Based on a referral they got from another one of their facilities, they called to get more information on a Cabinet Cooler System. For total dust exclusion, our Non-Hazardous Purge systems are ideal…they’re thermostatically controlled, so compressed air consumption is responsible and efficient, but they also provide a small, continuous flow, even when the thermostat set point temperature is attained, and the solenoid valve is shut. This keeps a low positive purge volume of clean, dry air in the enclosure.
The caller already had the data from our Cabinet Cooler Sizing Guide, so specification was quick & easy. A Model NHP4340 NEMA 12 Non-Hazardous Purge Cabinet Cooler System – 2,800 Btu/hr – w/Thermostat Control was ordered and installed the next day. We keep them in stock for situations just like this.
If you have heat issues with electrical & electronic equipment enclosures, give me a call.
