Flexible silicone heater

APPLICATION

Heating and maintaining the set temperature, anti-condensation and anti-icing.

Due to elasticity and small thickness, the heaters are suitable for heating non-standard shaped surfaces where rigid heating elements are not applicable.

Silicone heaters are suitable for the heating of:

Evaporators
Defrosting systems for heat exchangers
De-icing ventilation systems
Molds and equipment
Metal drums, IBC, and containers
Packaging machines
Hydraulic equipment
Batteries
Aircraft engines
Sterilizers, incubators, blood analyzers
Catering equipment
Laboratory equipment
Cosmetology equipment
Floors

FEATURES

Silicone heaters are easily attached to surfaces and provide uniform heat transfer.

Standard-sized heaters are manufactured for typical applications. The heater power and operating voltage can vary according to the customer’s specifications.

We manufacture heaters of the required geometry. The template for the conduit etching is set by the CAD file.

The heaters can be operated for a long time under the exposure to atmospheric factors and some chemicals. The materials are environmentally friendly and do not emit harmful substances during operation

STRUCTURE AND OPERATION

The heater is manufactured on the base of etched nickel alloy foil. This technology enables to produce elements of the required shape with the required electrical characteristics. For example, high power elements with a double loop.

The conductive element is hermetically packed in a silicone sheath. The material and type of contact wire insulation depends on the task and can be single/double-layer, Teflon/silicone. The end section is vulcanized.

Due to thermally stable silicone, the heaters can be used at temperatures of up to 200°C. The product thickness can be varied from 0.8 to 1mm. Polyester (110°C, 0.20-0.25mm) or polyimide (260°C, 0.10-0.15mm) can be used as sheath materials.

The temperature is set and controlled using the built-in thermostat or an external controller with a Pt100 sensor or a thermocouple.

Flexible heaters are mounted on a self-adhesive layer. The joint has good adhesion to stainless steel and plastics. The installation method is applicable up to 100⁰C.

For high-temperature applications (up to 200 °C), the silicone heater is attached with a one-or two-component vulcanizing adhesive.

Barrel heating belts are mounted with pressure springs. The flexible heater is securely fixed to the barrel. Easy removal and mounting.
