Within the industrial environment being machinery, manufacturing process or otherwise there is constant demand for process heating equipment. There are several types of heat mats, all delivering specific requirements and needs.
The main heater pads are silicone heater and mica heating pads. There are different types and designs of both of these pads, dependant upon your heat source and temperature.
Silicone Heater Mats, also known as a silicone heater pads are a flexible heating device made from silicone rubber. Wires or foils are laminated between the sheets of silicone, offering a rapid and efficient transfer of heat. These heater mats can then be connected to heat control devices such as thermocouples, platinum sensors and limit switches to deliver the required heat or temperature.
There are 2 types of Silicon Heater mats, wire wound and etched foil. Wire wound mats are robust and ideal in applications where the heater is installed or regularly removed, applications include industrial catering units, aircraft and laboratory equipment. Etched foil heater mats have chemically etched foil heating tracks laminated between the silicone sheets. These provide a very precise and even heat and are temperature accurate. Applications include laboratory equipment, anti-condensation heating, GRP pipe curing systems, satellite dish snow melting
Mica heating pads also known as micathermic heater pads are space heaters that are used to heat only a small single area to a very high temperature.. They are made with thin sheets of mica and are able to withstand extremely high temperatures. They are used to heat surfaces with electrical appliances, typical applications include air heaters, enclosure systems, food service equipment, process and packaging equipment.
There are 2 types of mica heating mats, flat design and band design. Flat design are small and thin, they are best suited to flat surfaces and for fitting between two metal surfaces where one or both require heating. Band designs are encased in brass casing and typically used in dies, platens, moulds and process machinery.
