Norseman™ Heaters are Durable

With anodized, copper-free aluminum housings and heat sinks and nickel-plated, low-watt-density elements, the Norseman™ line of electric explosion-proof heaters is designed to provide years of reliable, low-maintenance service.

Norseman™ Heaters Have Simplified Wiring

To facilitate installation, Norseman™ heaters employ the patented x-Max® housing with screw-on covers and slide-out terminal block trolley.

Norseman™ Heaters Use the Innovative x-Max® Terminal Housing

Thermon Heating Systems’ explosion-proof terminal housing features the unique x-Max® “Track and Trolley” system. Typical uses include a terminal enclosure, a control station, or a junction box, or it can be adapted for use in custom-engineered applications. Five standard diameters, offered in lengths up to 3" (76 mm), can cover most of your explosion-proof housing requirements. No longer is it necessary to remove dozens of bolts to gain access to housing components for installation, adjustment, or servicing. With longer type XH housings, components are mounted to the trolley. To service, simply unscrew the end cover and slide the trolley out of the enclosure.

The “Track and Trolley” wiring system allows the user to mount all electrical components to an aluminum “Trolley,” make all wiring connections outside of the enclosure and simply slide the “Trolley” along the extruded “Track.” Series 1 and 2 housings use extruded aluminum trolleys, and Series 3, 4, and 5 housings use trolleys made from 14-gauge sheet metal.

Typical applications include:

-Control cabinets
-Instrument enclosures
-Small storage rooms
-Cabinets for volatile products

Construction

The Norseman™ XPA Explosion-Proof Panel Heater’s custom extruded aluminum convector assembly features a high-density fin array to maximize surface area and ensure safe and efficient convective heat transfer. The Norseman™ XPA heater is anodized black for maximum heat transfer and corrosion resistance.

The standard heater is configured with an explosion-proof junction box and includes a mounting bracket and hardware. As a precaution against excessive convector temperatures, the unit comes standard with two levels of safe temperature control. The primary control is a nonadjustable thermostat set to control the space temperature between 50°F and 64°F (10°C and 18°C). The secondary control is a thermal fuse with a nonadjustable limit set to the maximum temperature allowed for the temperature code classification. Optional junction boxes, optional pre-set thermostats, adjustable thermostats, and protection grilles are available.
