UL Listed Enclosure Heaters for Equipment Protection

The range includes a steam-powered ThermaGuard Steam Heater, an electric ThermaGuard 100W Finned Heater, and the electric ThermaGuard Heated Enclosure Liner. The products differ in heat source, construction, mounting approach, enclosure access, and hazardous-area suitability. Product selection should be matched to the required operating conditions and installation requirements.

Yes. The products are designed for enclosure heating and freeze protection in cold environments. The steam heater is designed for freeze protection at 50°F, while the 100W finned heater maintains 40°F in specified extreme cold conditions with insulation. The heated liner is intended for extreme-temperature enclosure applications, with output selected by heater cable configuration.

The ThermaGuard Heated Enclosure Liner is identified for use in hazardous T6 areas, with heater cable ratings for specific hazardous-area classifications. The other listed heaters do not have a specific protection rating in the supplied product data. Confirm the classification, installation method, and applicable project requirements before specifying a heater.

The category includes both steam and electric AC heating options. The ThermaGuard Steam Heater uses steam and is specified at 50 psi and 300°F operating conditions. The ThermaGuard 100W Finned Heater and Heated Enclosure Liner use electric AC power, with electrical requirements varying by product and configuration.

Installation varies by model. The finned heater uses a 360° universal mounting bracket for vertical or horizontal orientation. The heated liner uses a removable two-piece design with integrated heater cable entry. Steam heater installation requires suitable steam connections and should follow the applicable product documentation and project installation requirements.

Consider the enclosure size and construction, required temperature, environmental conditions, available power or steam, installation orientation, instrument access, and hazardous-area classification. The available products include a 100W finned heater, a steam heater, and a heated liner with output from 108 watts to 720 watts. Terrapin Industrial can provide configuration and technical guidance.
