Backer cast iron element

For air heating and radiation heating Backer tubular element are the most popular alternative. Backer manages a large number of production techniques, giving a choice within a wide range of element types. An optimal heat solution of an application is decided by user environment and operating temperature. Backer for example can supply element with an operating temperature of as much as 900°C.

Benefits – Stone heaters

The Backer Cast Iron Element offers good heat accumulation and high inertia. A heating element is fixed into the cast iron part with a design that guarantees an optimal heat transfer from the element. It can be designed with different types of fins to fit all types of radiators. The Backer Cast Iron Element is highly appeciated for the soft heat it conveys.

• Aerodynamic fins for optimal convection
• Increased radiation area
• Increased heat transfer from tube
• Soft radiation heating
• Heat accumulation / high inertia

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.

The most commonly used types:

Wiring material	Insulation material	Max. operating temp.
Copper	–	180°C
Copper	Silicone	180°C
Copper	Fiberglass/silicone	180°C
Nickel	–	400°C
Nickel	Ceramic bushings	400°C
Nickel	Fiber glass/silicone	200°C
