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:
Oil and solvent 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).

Applications requiring a flexible shape or design
National Plastic Heater supplies silicone rubber heaters for many different applications
such as industrial catering, battery warming, environmental control or electronics
(particularly telecommunications), laboratory equipment and anti-condensation. The
uses for polyimide heaters are infinite as they can suit any application requiring
surface heating up to 200°C. Their suitability for arduous conditions has been proven
in applications from polar expedition to space exploration. We are the final frontier
in polyimide heaters!
THERMAL OR TEMPERATURE CONTROL FOR SILICONE RUBBER ENCLOSURE HEATERS:
NPH silicone rubber heaters can be supplied with factory fitted sensors and switches
to suit all types of instrumentation. Available from stock are PT100’s, J, K and
T type thermocouples, bi-metal thermostats and thermal fuses. We also fit customer
specified thermistors and other resistance temperature devices as well as extruded
pockets for customers to fit their own sensors. Separate mechanical or digital thermostats
can be supplied for process control.
