A Stelpro washdown unit heater offers fan-forced heat in industrial areas where the potential for exposure to moisture and corrosion occurs. This means each heater will not rust or oxidize in harsh industrial climates. Stelpro's SWU series washdown unit heaters function as totally enclosed and watertight wall or ceiling mounted fixtures.
Stelpro’s SWU series heaters offer a NEMA 4X rating. NEMA ratings determine where you can use an enclosed fixture and what conditions the fixture can withstand. A NEMA 4X rating indicates protection in harsh environments against corrosion, splashing water, hose-directed water, and windblown dust and rain.
Stelpro SWU series offers these shared features:
Add-ons for the SWU series units include:
Stelpro also offers finned tubular elements, a washdown and corrosion resistant wall mounted thermostat, and a 120V control circuit.
You do not want to use a washdown unit heater in a home or office. Instead, Stelpro washdown unit heaters work well in areas where they may see moisture or experience direct exposure to water, such as car washes, dairy or food processing plants, or waste-water treatment plants.
