Main features
Non-flexible silicone rubber heaters are made of fiberglass reinforced laminated silicone rubber sheets, vulcanized together through heat and high pressure on both sides of an embedded specially formed heating wire element. Fiberglass-reinforced silicone rubber gives the heater dimensional stability.
The intimate bonding of the heater on a thick aluminum plate allows to increases the power surface load, and eases the mounting on flat surfaces in industrial applications
Silicone is used because of its high temperature resistance (Permanent temperature up to 200°C (390°F), high thermal conductivity (~7 10-4 W/cm.K) and good electrical insulation properties (~12KV/mm)
This series is distinguished by the use of a remote electronic control system, with PID action and automatic adjustment of parameters, with digital display of the measured value and digital display of the set point, connection by waterproof connector for easy disconnection of the heater, and IP65 ingress protection class for the whole assembly. This allows its use in most of industrial applications
Other general particularities of these heaters are:
– Not affected by vibration or flexing,
– Lightweight,
– Comply with UL94-VO (flame retardant) and ROHS,
– Low smoke and low Toxicity,
– Silicone is non-toxic, and moisture and chemical resistant
Main applications
Silicone heating elements on aluminum plates are a simple and industrial solution for heating flat surfaces. They are sturdy, easy to install and heat quickly and evenly.
Some typical examples of applications are:
Heating of hoppers, electrical cabinets, hot plates for the food industry, reheating tank bottoms.
In addition to their temperature control system, they
can receive temperature sensors, temperature limiters, thermal fuses.
