Silicone heaters

The silicone heaters are thin, flexible and resilient elements. They can be formed and installed on devices of various shapes, while maintaining the highest efficiency and reliability. The use of of heaters of this type allows additionally for frequent heating and cooling, as well as for uniform heating of the surface.

Heat insulation

• flat shape: due to it versions with openings and grooves are possible
• maximum operating temperature: up to 260°C
• optimum operating temperature: up to 220°C
• maximum power: up to 6 W/cm² (optimum power: 0.8 W/cm²)
• a low weight allows for use in places where there is a limitation for weight and surface
• the heating elements are closer by 0.08 mm to the heating part, they provide heating and cooling
• a uniform placement of 6 mm tracks from the side of the heater allows for more efficient heat transfer

The heating mats are made of strong, high-quality, moisture-resistant silicone rubber, inside which some heating coils are embedded, made of the highest-quality wires wound on a fiberglass rod. This material can be easily fastened on or connected to an arbitrary surface. Many our designs are certified by VDE.

• in medical equipment, for example during conducting blood tests, in respirators and hydrotherapy baths
• in communicators
• for protection from freezing in a heavy machinery park: pneumatic equipment and hydraulics
• heating batteries and storage batteries
• in semiconductor devices
• in machines for heating foods

Standart versions

The standard version has copper wires in Teflon insulation 305 mm (or to order), heat-resistant up to 200°C at 600 V. The direct connection between the power wires and the heating element is covered with a vulcanized cover. Power outlets on any side (typical solution — on the short side).

For better protection against moisture, the connection between the wires and the heating element is covered with silicone rubber with heat-resistance up to 150°C at 600 V. Any length of current leads may be available. CAUTION: Excessive exposure of the heater to moisture will accelerate heater failure.

The leads from the middle of the heating mat are manufactured of copper wires in Teflon insulation of arbitrary length, with heat-resistance up to 200ºC at 300 V.

Many three-dimensional shapes such as cylinder, cone, cube and others, can be provided to order.

We offer heating mats with special cuts and grooves anywhere in the element to individual orders of the customers. The resistive heating element can be as close as 3 mm from the edge. The standard distance is 6 mm.

Various methods of installation of all developed units are possible with quick fastening. Among them, we distinguish three types of glued and mechanical fasteners.

They are suitable for quick and easy installation. Put on a smooth, grease-free surface an adhesive mat, first removing the protective envelope, then spread a silicone heater on the mat and press it. Attention: this installation method is not recommended for curved surfaces and heaters with power of more than 0.8 W/cm² and an operating temperature of more than 205°C.

The heaters applied onto surface, vulcanized at room temperature in order to connect more strong. The heaters mounted in such a way were ready for use after 48 hours. Resistant up to 205°C or 260°C. Packing method in tubes of 90 and 355 ml. For larger heaters, a two-component adhesive is recommended.

The two-component contains a resin and curing agent, which are easily mixed and can be easily applied with a brush. The adhesive is resistant up to 175°C.

Fasteners — when the silicone heater is used in many places and is often moved, their use is recommended. Other types of mechanical fasteners: latches, springs.

Several types of temperature sensors are possible, which interact with silicone heating mats. The following options are possible: settable thermostats, adjustable thermocouples, thermistors or resistance sensors (RTD). They can be integrated with heating elements (placed in silicone). Additionally, the thermostats can be ordered separately from heating elements, which allows direct control of the process temperature.

There are several types of programmed thermostats. The thermostats are embedded in silicone rubber and have a standard wire length of 305 mm, other wires are available to order. The thermocouples, RTDs and thermistors are placed under a vulcanized protective layer of the silicone heater.

We offer separate thermostats, which allows for direct control of the process temperature so that there is no limitation consisting in control of only the heater.

We offer several types of adjustable thermostats. The thermostats are embedded in silicone rubber and have a standard wire length of 305 mm, other wires may be available to order. They allow you to control the temperature of the heaters in the range of -5 ± 165°C or 40 ± 260°C.

We offer adjustable thermostats separately from the heater, which allows for direct control of the temperature of the processes so as not to be dependent only on the control of the heater.

S — denotes that the thermostat is delivered separately.

To increase the heating capacity of the silicone heaters, it is recommended to insulate the heaters with a special silicone sponge glued to the heater on one side. The following thickness sizes are protruding: 1.6; 3; 6; 10; 13. Thermally insulated heaters retain their elastic properties. An aluminum cover can be further fixed to the bottom of the heater to minimize heat radiation from the heater in an unwanted direction. An additional advantage of this cover is that it is easy to keep cleanness.
