While the materials that comprise the hot-side of our thermoelectric air conditioners are corrosion resistant (Type 304 stainless steel and Aluminum), some caustic ambient environments can cause surface corrosion even on these robust materials. Our black epoxy –based powder coating adds an additional level of protection against corrosion on the hot-side of the air conditioner as it is rated for salt spray resistance of 1000+ hours (ASTM B117). Most commonly it is applied to just to the aluminum hot-side/ambient side heat sinks (#BE1). In extreme cases it can be added to the entire hot-side/ambient-side of the air conditioner (#BE). This optional coating is available on all of our ThermoTEC Series Thermoelectric Air Conditioners.
