Shielded Mica Heating Collar
Usage:
Shielded mica band heaters are intended for conduction heating of cylindrical parts. They are used in the injection and extrusion of plastic materials or in specific applications such as the heating of tanks from the outside.
Maximum temperature of use of heating collars 350°C, maximum load 4.2W/cm².
Technical description :
- Resistive alloy wire wound on a mica paper backing;
- Mica paper insulation;
- Shielding in treated steel sheet or 430 stainless steel;
- Minimum diameter: 40 mm, maximum diameter: 1200 mm;
- Minimum height 20 mm, maximum height: depends on the diameter;
- Voltage: from 24 to 440 V single-phase or three-phase;
- Number of tightenings: depending on the height of the collar.
Possible variants:
- Holes for passage of probes, pipe tapping, etc.;
- Compensated tightening (springs or Belleville washers);
- Half collar, portion of collar;
- Quick assembly (onesie);
- Thermostat under cover;
- Integrated thermocouple.
Assembly :
The nominal diameter of the band heater is the same as that of the part to be heated. It is recommended, during assembly, to ensure a good tightening of the heating collar and to perfect it after 30 minutes of heating. To ensure proper operation of the collar heater, the user must provide a temperature control system. Shielded mica collar heaters are not liquid (water) splash proof.
