NPH silicone rubber enclosure heaters are designed for easy installation and safe operation. These rectangular-shaped wire wound silicone rubber heaters are vulcanized to an aluminum mounting plate with mounting holes. They provide superior protection for enclosures of all types against condensation, humidity and freezing. It is recommended that the enclosure heaters be used with a thermostat either built-in or mounted remotely to limit the maximum temperature reached and conserve energy.

A wire wound silicone rubber heater with ambient sensing thermostat and aluminum mounting plate are designed to prevent humidity and moisture accumulation in electrical and mechanical enclosures. Enclosure heaters can be supplied with thermostat separate from heater or without mounting plate.

With built-in ambient sensing thermostat, the minimum width is 2". Available lengths are from 5" to 40" at 5 watts/square inch. Aluminum mounting plate is 1/2" wider than heater. Mounting slots are conveniently located. The suggested mounting is vertical with the thermostat at the bottom as shown.

Available thermostat setting is 40°F (4°C) 40°/55°F (4°C/13°C). Consult NPH for other settings available. Minimum quantity may apply.

 

Silicone Rubber Enclosure Heaters- Wire WoundUsing evenly spaced resistance wires laminated between sheets of silicone, wire wound silicone rubber heater mats are ideal for prototyping or problem solving applications. Manufactured to customer specifications they can be made in a limitless range of shapes and sizes. High flexibility can be obtained using tough, robust silicone materials which are finding ever increasing applications in the industry. Silicone's wide temperature range, tolerance of -60 to +230 °C and superb electrical properties give it a distinct advantage over other forms of heating.

This construction uses tubular heaters-Incoloy, stainless steel and titanium sheaths are available

 

The finned strip heater construction uses a ceramic/mineral insulated strip/channel heater that is lined with fins for faster and more efficient heat transfer

  

Edison Screw In Ceramic Cabinet Enclosure Heaters:

 

This Edison Screw-In Bulb Style E-Mitter® is a hollow tube-shaped ceramic heater. The heater's unique 360° radiating pattern makes it ideal for use as an enclosure heater. The unique thin wall construction and geometrical shape of the EHC style heater facilitates very fast heating and cooling rates.
