Electric heating elements (EHE) are used to heat various environments by convection, heat conduction and / or radiation and are used as components in heating installations
The company “Teplobak” offers electric heating elements with capacity from 2 to 15 kW.
EHE of “Teplobak” are made of highly quality stainless steel Incoloy 800 and refers to the class of wet thermoelectric heating elements. They have a built-in thermostat and work in the temperature range from 30° to 75°C. Thermostat with smooth adjustment and temperature limiter protects the heater from overheating. When the temperature is 75°C, EHE switches off automatically. To extend the service life of EHE, it is recommended to operate the appliance between 50˚ to 60˚Ñ.
The feature of “Teplobak” EHE is the presence of cold zone in the lower part of the body, thus avoiding local overheating of heating element in the mounting site and thus extending the life.
EHE basis is thin-walled metal shell of a certain diameter, inside which is a spiral with considerable resistance. Ends of the spiral are connected with special rods, which are attached outside to the contacts.
Between the contacts and the ends of pipes is installed insulator. The space in the shell of EHE is filled with filler, which has higher dielectric properties and has high thermal conductivity.
Crystalline magnesium oxide is commonly used as a filler of EHE. End face is filled with special heat-resistant waterproof paint that minimizes environmental impact on electrical parameters of EHE filler during storage and operation.
Thus, during EHE operation is released heat when an electric current passes through wired spiral. Heat energy in turn passes from the spiral through the shell to the environment.
EHE “Teplobak” in its construction has threaded hexagon head for the possibility of its mounting into heat accumulator.
Our company has always in stock at the warehouses EHE “Teplobak” with power from 2 to 15 kW, the use of which in tanks-heat accumulators helps to achieve maximum efficiency of the combined heating system.
