SWU Series Washdown Unit Heater
What is a washdown unit heater?
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.

Where do you use a washdown unit heater?
