Silicone surface radiators can be produced up to a maximum width of 940 mm and a maximum length of 3000 mm.
The heating conductor which converts electrical energy into thermal energy, can be designed as:
- Wound wiret
Ideal for prototypes or low numbers of pieces since the non-recurring costs are low. - Etched film
Ideal for medium and higher numbers of pieces. This provides more exact temperature distributions than the design with its wound wire.
The heating conductor is embedded between fibre-glass reinforced silicone mats, each having a thickness between 0.7 and 3 mm depending on the application
The thermal stability of the silicone mats is -60 - +200°C for the normal design and -20 - +180°C for the self-adhesive variant.
The silicone heaters can be connected to the surface to be heated in different ways:
- Pressing on by a pressure platee
- Bonding by a self-adhesive rear side
- Bonding by temperature-stable silicone
- Fixing by adhesive strap or pressing spring
Wherever heating is required, control is also necessary in almost all cases. We are of course prepared to deliver the corresponding controller for your ceramic sectional radiators. There are different variants of control which can be selected according to the desired quality.
I. Controllers
- Electronic ON-OFF control or PID control. (-> ON-OFF control switches off the heater if the temperature is exceeded, and switches it on again when the temperature falls below its lowest value. Thus, the temperature will always oscillate around the setpoint. The algorithm of the PID controller will optimally compensate the control fluctuations.)
- Load switching by contactors or wear-free semiconductors (thyristors). (-> contactors are wearing parts and must be replaced after approx. 100,000 make/break operations; thyristors switch quickly and without any wear but generate more heat losses than contactors.)
- Electromechanical control.
Thermostats installed on the tool are price-efficient controllers whose accuracy is sufficient for many applications.
II. Sensors
- Thermal protectors and limiters as capillary thermostats (as a safety design as well).
- Temperature sensors for tool and heating element temperatures.
A variety of designs is available for silicone heaters. We are prepared to agree with you on the variant suitable for your application, considering factors such as temperature, mechanical load and environmental influences.
I. Electrical connections
- Glass-silk-insulated nickel wire for temperature of up to 250°C
- Teflon-insulated nickel wire for temperatures of up to 220°C and moisture-proof design
