Resistance Heater: Tubular heaters

• 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 8.1 mm, 8.5 mm and 6.5 mm
• Tube jacket length from 400 to 4300 mm
• Connection area unheated, unheated lengths according to demand, preferably 50, 75, 105, 140, 180, 280 and 900 mm
• Max. operating voltage 500 V
• 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 enquiry.
• 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
 

Various 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
 

Application examples
