Domestic Heaters
T he choice of heat source for domestic heating will depend on several factors. Independently, K.T.E.T. produces heating elements for numerous electric heating applications as well as for equipment using electric heating elements as complementary heat source or for functions where electric heating is needed..
E lements for domestic heating applications such as electric radiators, convectors and towel dryers, have been produced since the very start of KTET and are still one of the largest product areas in the Backer group. During the last few years, the demand of new heating elements has been intensified and KTET is continuously testing complementary technologies in the development of elements for electric heating applications.
Defrosting Heaters
I n all kinds of freezing, cooling and climate controlled plants there is a need for some kind of defrosting. KTET provides different technologies for this purpose, tubular elements being one of them.
- Type of heating: Frost protection, Defrosting
- Material: Stainless Steel AISI 304/EN 1.4301, AISI 316L/EN 1.4404
- Dimension: Ø 6,8,12,14,16 mm
- Field of application: Freezing and cooling equipment, Compressors, Climate plants
Cast-In Elements
C ast-in elements can be used for indirect heating of liquids for instance in tanks, but also for direct heating in oil pre-heaters. KTET tubular heating elements can be produced cast-in in an aluminum alloy. The cast-in technique offers advantages such as influencing the temperature regulation of a large mass, uniform heat emission and low operating temperatures thanks to the fact that surface enlargement can be integrated with the element. Embedment of a tubular heating element increases its heat-emitting surface and makes it possible to adapt the element to different applications.
- Type of Heating: Indirect liquid heating, Contact heating, convection/air heating
- Material: Different aluminum alloys brass
Immersion Heaters
K
TET manufactures screw plug immersion heaters for heating of water and oil. Available in copper, stainless steel or stainless steel with brass plug. Plug available in 1″, 1 1/4″, and 2″.
Immersion heaters are used as heat source in domestic water heaters, dish washers, industrial baths, oil radiators and towel dryers among others.
The immersion heaters are built with tubular elements with flanges, nipples or plugs soldered or welded onto them. The immersion heater can be fitted with thermostat, temperature limiter and connection box. There are also thermostats and temperature limiters for mounting inside the tubular element.
As alternative we also offer immersion heaters made of ceramic elements.
KTET holds a standard range of immersion heaters on stock for water or oil heating, in different designs for fast delivery.
We also produce according to customer specification. Contact us if you don’t find what you are looking for and we will help you.
Unit Heaters
K
TET systems generally have basic design elements, like an outside air intake and an air handling unit that consists of a system of fans, heating and cooling coils, and air filters. There’s also an air distribution system and air exhaust system.
Part of the air distribution system is the duct system, which provides the controlled path for the air to flow throughout the home, commercial space or factory. It consists of a branching network of round or rectangular tubes which may be made out of materials like sheet metal, fiberglass duct board, and insulated plastic. These tubes are located within the walls, floors, and ceilings.
immersion heaters with special insulation
T his heaters consist of heating elements mounted in tubes of porcelain, acid-proof steel, steel, titanium, quartz glass Or tefoln. The uses for over the side immersion heaters include the heating of chemical baths, de-acidification of baths and degreasing of baths. The immersion heaters consist of ceramic elements assembled in tubes of different materials. The choice of material is important for the life of the heater, and dependent on the fluid in which the heater will be used.
