Silicone Rubber Enclosure Heaters
SILICONE RUBBER ENCLOSURE HEATERS - PRODUCT DESCRIPTION
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.
Enclosure Heaters with Ambient Sensing ThermoStat
Silicone Rubber Enclosure Heaters- Wire Wound
Using 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.
Silicone Rubber Heaters – Etched Foil
Computer designed chemically etched foil tracks are laminated between thin sheets of silicone to give precise even heating. Suitable for both low and high volume production etched foil heaters have rapid heat up properties with precise temperature control. Heating solutions are available in a limitless range of etch foil heaters to customer specification for multiple industries. 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.
Silicone rubber heaters are extremely versatile and operate efficiently in many environments. Some distinct advantages of silicone rubber heaters are:
- Moisture resistance
- Oil and solvent resistance
- Chemical resistance
- Outdoor exposure
- Extremely thin profiles
- Conform to almost any shape
All silicone rubber heaters are built to order, but rush delivery is available. In most cases, NPH can deliver custom silicone rubber heaters within 48-96 hours. All NPH flexible heaters are available with custom design modification. Custom designs are welcome. Please contact us with your requirements.
Silicone Flexible Heaters - The particular application conditions of aerospace, medical, composite fabrication, optical equipment and computers often require flexible heating elements. NPH offers a wide assortment of in-stock and custom flexible heaters in Kapton® and silicone rubber materials to suit most any of these needs. Silicone Rubber heaters permit composite bonding and curing, as well as repair and fabrication operations. Equal length circuits and a cool tab are provided, while a fiberglass reinforced heater cover means long service life and increased durability. Standard watt density is 5W/in2 (0.8W/cm2). All standard heaters are UL Recognized. Many sizes in stock from 6” x 6” to 20” x 20” (152.4 mm x 152.4 mm to .508 m x .508 m).
