- Basic information

The REISSMANN Sensortechnik heater bands were

specifically designed for the electric motor industry.

These heater bands are delivered as a finished product,

in various combinations, of length and power output.

- Application

The heater bands prevent condensation in electric

motors and also protect against frost damage. If

condensation occurs inside the motor, creepage

currents and short circuits may occur.

- Advantages

• exclusive usage of silicone-free material

• prevention of „outgassing of silicone“

• protection of people and equipment, from dangerous

gases

• very flexible design facilitates the matching of product

to application

- Construction

The carrier material consists of a glass yarn and a

resistance wire that is wound round the glass yarn.

Afterwards the glass yarn is insulated by Teflon (Fig. 2).

The junction between the lead-in and the resistance

wire are insulated on both sides with shrink tubes. For

protection against damage, from external sources, the

entire heater band system is sewn into a fiberglass hose

or sleeve (Fig. 1 and 3). The sewing in of the lead-in, at

the end of the fiberglass hose, gives additional strain

relief at the junction between the Teflon insulated

resistance winding and the lead-in.

UL: E325880
