Tubular Heaters Explained

Tubular Heaters

Tubular heaters are used in a large variety of applications. 

High power density and installation advantages offer solutions for applications requiring high consistent heat such as outside enclosures during winter temperatures.

The elements can be adapted extensively to the demands. There are various tube jacket materials available to match different requirements.

 

Application Examples

  • Grills, baking ovens, roasting dishes, baking surfaces
  • Washing machines, dishwashers, instantaneous water heaters, boilers, water heaters
  • Heating molds and tools
  • Room heaters, air heaters, radiant heaters
  • Steam generators, evaporators, dryers
  • Deep fryers and dripping pans
  • Heated casting systems

Functional Characteristics

  • Defined heating capacity through resistance wire technology
  • Heating wire embedded in magnesium oxide, insulated towards tube jacket
  • Heat dissipation through contact, radiation, or convection

Design Features

  • Tube jacket diameters 8.5mm
  • Tube jacket length from 400 to 4300mm
  • Connection area unheated, unheated lengths according to demand, preferably 50, 75, 105, 140, 180, 280, and 900mm
  • Max. operating voltage 500V
  • Power tolerance according to VDE 0700 EN 60335
  • Tube jacket, bendable, blank annealed, bending shape as required, preferred bending radii R15, R20, R25, R30, R35, R45, R50, R60, R70, R80, R100
  • Corrosion-resistant through suitable choice of materials for tube jackets 1.4541, 1.4571, 1.4435, and 1.4876. Other materials upon inquiry.
  • Electrical connection: Threaded bolt M 4, bolt smooth Ø 2.5 resp. 3.5 mm, blade terminal 6.3mm, stranded wire connection

Design

  • Bent according to drawing or sample
  • We can make suggestions for optimum design of the heating elements if so desired
  • Attention should be paid to the transition from the non-heated section into the heated section, this should not lie in the bend
  • The minimum bending radii are R =15 mm, with material 1.4876 R = 20 mm

Fastening Elements are Available for the Installation of the Tubular Heaters

  • Thread nipples hard soldered, welded, pressed on
  • Threaded flanges
  • Flat flanges, round and rectangular
  • Mounting plates according to specification or recommendation
