Mini-Radiant/Radiant Heaters/Fan Heaters/Compact Fan Heaters.

Low temperatures and high humidity are the biggest dangers for electrical enclosures.

Pfannenberg heaters, thermostats and hygrostats prevent condensate build up and therefore protect against corrosion.

As long as under load, heat dissipation from components will prevent any condensation buildup. When there is no longer any heat load due to system downtime, there is a potential danger that components within the cabinet will form condensation. This varies based on the dew point. And this is precisely where the function of the Pfannenberg cabinet heaters, designed as radiant heaters and fan heaters, begins.
