Backer manufactures tubular air heating elements for several different appliances, such as electric water heaters, dishwashers and washing machines, boilers, coffee machines, fryers, industrial baths and oil filled radiators.
Benefits – Square finned elements
Heating element with dia. 8.5 mm and 14 mm can be fitted with fins to increase their heat dissipation surfaces. Fins are available in steel for soldering or in zinc-aluminum alloy for press-fitting to tubular elements of 8.5 mm diameter. Fins in zinc-aluminum alloy are available for press-fitting to 14 mm dia. elements.
- Reduced surface temperature
- Increased radiation area
- Compact design of application possible
Examples of applications | Tubular air heating elements for everyday and everywhere

Fixing and connection devices
Cost savings can often be made if elements are fitted with connection and attachment devices during manufacturing. We offer several standard solutions. We can also supply special flanges and alternative methods of fixing made completely according to our clients’ specifications. When selecting connection and fixing devices it is often important to bear in mind the size of the series. Do you want to know more about our fixing and connection devices? Please contact us.
Types of cables and wiring
The heating elements can be supplied with connecting wiring which is normally spot welded to the terminal pins. Uninsulated as well as insulated wiring is available. Uninsulated wiring can be fitted with insulating tubing. The joint between the wiring and the terminal pin can also be fitted with insulating tubing if required.
