Blocks of tubular electric heaters

Blocks of tubular electric heaters

Blocks of tubular electric heating elements are applied mainly for heating liquids and oil and used in water heaters, steam generators, boilers and other industrial installations and household appliances. A block of electric heating elements consists of one or more tubular electric heating elements as well as of finned electric heating elements fixed to a common flange for mounting in the installation. Contact terminals of electric heating elements are wired electrically into one heating device. Flanges are made of various materials (carbon...

Tubular electric heaters for switches

Tubular electric heaters for switches

Switch electric heaters are intended for switches of the railroads in the areas with temperate and cold climate for operation under temperatures from –40C to +7C. Switch electric heater represents a metal body of flat-oval section with a spiral made of high ohmic resistance wire. The heating element is insulated from the shell by filler material (periclase). Current supply wire is made in frost resistant version with the length of 4 m connected to contact terminals of electric heater through the hermetically sealed sleeve preventing...

Tubular electric heating elements

Tubular electric heating elements

General data These electric heating elements are designed for heating various environments by way of convection, thermal conductivity and irradiation through conversion of electric power into thermal power and used as component parts of industrial installations and household appliances. Electric heating elements can operate in most diverse environments including aggressive mediums such as acid, alkali solutions, low-melting-point metals, saltpeter. Operating temperature on the electric heating element’s surface varies from tens of degrees...

Cartridge type tubular electric heating elements

Cartridge type tubular electric heating elements

The necessity of local heating of a metal equipment details arises more and more frequently in present-day industry. One-end heaters, the invention, which is widely applied now, has become the solution of this problem (making of contact outputs on one side of the heater is the peculiarity of such heaters). The said heaters, made of stainless steel, have become the reliable machine parts. Sphere of application Cartridge type tubular electric heating elements (often called finger tubular electric heating elements) may be used not only for metal...

Finned tubular electric heating elements

Finned tubular electric heating elements

Finned tubular electric heating elements are used as components both of domestic and of industrial heating appliances (fan heaters, electric calorifers, electric convectors, etc.). Finned tubular electric heating elements are assigned for heating of air environments: stationery (S) and moving (O). Finned tubular electric heating elements are the elements, on which casing iron strap is fixed. Electric heater’s heat irradiation is increased thanks to increase in surface area, resulting in capacity increase in comparison with a non-finned...
