Data is given for illustration purposes only and does not release the customer from independent application tests. Design Drawing G 1 1 /4 G 1 1 /2 DBK s knowledge of thermal management gives us the experience to guide and support you with your technical challenges - we can manage the complete project from concept to full production release. Design Characteristics Heating elements for direct heating of Liquids, viscous substances, gases U-bend tubular heaters that are directly immersed in the substance to be heated. Heating elements are joined to a srew plug or to a blind flange thus forming a self-contained heating unit that can be furnished with enclosure and control device if desired. Screw plug made of, St7.2 or stainless steel Thread G 1 1/4", G 1 1/2", G 2" 2-6 tubes depending on thread of screw plug Blind flanges IAW DIN 2527 form B, Sizes B50, B65, B80, B100, B170, B175, B200, B250 Material St7.2 stainless steel on request Number of tubular elements according to application Capillary thermocouple possible, temperature ranges 0-85 C, C, C With enclosure, Ø 80 x 97, IP 65, with temperature limiter 110 C or 15 C inside Operating voltage 20V, 20/V Special voltages up to 500V Installation with gasket in threaded bore or with companion nut, for flat flange with matching companion flange Note that immersion heaters should not be operated under dry conditions Boiler, heating of vessels, containers and tanks, oil tubes, oil sump of engines, hydraulic equipment, deep fat fryers, fat containers, washing machines, steam generators, laboratory equipment, medical apparatuses, instantaneous water heaters Protection class I DIN EN Further Information: Industrial Thermal Management

Design Characteristics Design Industrial Thermal Management Heating elements for a wide range of heating applications. High power density and easy installation provide a solution for most heating applications. The elements can be adapted to most requirements. Various sheath materials are available. Controllable heat by resistance wire technology Resistance wire embedded in magnesium oxide thereby insulated from the metall sheath Heat transfer by conduction, convection or radiation. Sheath diameter 8.1, 8.5mm and 6.5mm Sheath length from to mm Connection area unheated, unheated lengths as required preferably 50, 75, 105, 140, 180, 280 and 900mm. Operating voltage up to 500V Power output tolerance conforming to DIN EN 605 (VDE 0700) - Sheath bendable, annealed, bending as required, preferred bending radii R15, R20, R25, R0, R5, R45, R50, R60, R70, R80, R100 Corrosion-proof by choice of adequate material Sheath materials , , and other materials on request Electrical terminations: threaded stud M4 unthreaded stud diam. 2.5 and.5mm blade terminal 6. Lead wires Bent according to drawing or sample If desired we will make proposals for optimum configuration of the heating elements Please note that the transition from heated to unheated section must not be located in a bend Minimum bending radii are R=15mm for R=20mm Further Information:
