Motor and machine protection 

Heater bands: 

specially for the electric motor industry 

Type HB... 

- 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.
