The most common problem generated by dust
If dust enters your cabinet, it will cause overheating. All components dissipate some heat to the surroundings. When dust accumulates on the surface, it prevents air from dissipating heat, since dust isn't a heat conductor. This is why the powder and bulk industry requires completely sealed electrical panels to avoid dust entering the system. This problem is not just for internal devices; if an AC cooling solution is installed, these contaminants tend to block the filters and make the cooling solution ineffective.

What to do?
First, determine the best solution for your application in specific. Some key factors that determine the best solution for cooling the electrical panel in the powder and bulk industry include taking into account the characteristics of the material; some substances generate hazardous locations, and appropriate certified units must be installed; if it's corrosive, the cabinet must be stainless steel; no outside air can enter the electrical cabinet, so a hermetic seal is required. The solution must be easy to clean, since dust will accumulate on the exterior surface, and filters must be easy to clean or replace.

Noren expertise
We have developed cooling thermal solutions for the powder and bulk industries for more than 50 years, with fully sealed Heat Exchangers that keep contaminants out of the electrical cabinet while efficiently dissipating the internal heat to the ambient air, without the use of a compressor or a sensible component that tends to fail. Noren Heat Exchangers require no maintenance and can operate in the most extreme ambient conditions. We have units for hazardous locations and type 4X units made of stainless steel for high-corrosive atmospheres.
