A stainless steel tubular element surrounded by a perforated protection and mounting bracket is designed to prevent humidity or moisture accumulation in electrical and mechanical enclosures. These items are also used to maintain temperatures in control cabinets within operating ranges of electronic equipment. Typical applications are traffic signal boxes, switch gear, cabinets, control panels and ATM's. Watts Volts Watts/Sq.In. 95 125 2.8 100 250 3.0 250 120 7.4 250 250 7.4 375 125 11.0 375 250 11.0

SILICONE RUBBER ENCLOSURE HEATERS

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 Ogden for other settings available. Minimum quantity may apply.
