Pumphouse Heater U Series
Engineering Specifications
The U Series Pumphouse Heater
The U Series heater is designed to reduce moisture from mechanical equipment and keep pumps, valves, and farm
machinery from freezing. Having the radiant heat absorbed by the metal equipment makes this heater more effective than convection
heaters. The built-in thermostat turns off when the ambient temperature is safely above freezing. An optional 304 Stainless Steel
(Add-SS to the model number) version helps prevent corrosion associated with high moisture locations like pump houses. A steel guard
helps keep foreign objects away from the element. This heater is simple and reliable with no moving parts to wear out or maintain, making
it an inexpensive choice for freeze protection. Specifically designed to operate in both vertically and horizontally positions.
Element: 304 or 840 Stainless Steel.
Thermostat: Built-in snap action with a range of 40° to 90°F.
Safety Limit: Capillary tube running the full length of the element provides over-temperature protection then automatically resets when temperature drops.
Enclosure: Steel case with an expanded steel metal element shield (optional 20 gauge 304 Stainless Steel on -SS model).
Safety Standard: cETLus
