Nozzle band heaters: general description

We have a wide range of models of nozzle band heaters, with which we are going to cover each of size requirement and working temperatures. The models are two, RF14 and RF16 for a variety of very diverse measures and if necessary also feasible as oversize.

The model R14 is a band heaters which allows a great flexibility of use since the electrical connection is inside the package and the resistive cables can adapt to any wiring requirement, also find their application in all those cases where there is corosiva action due to aggressive materials.

The model R16 is a band heaters to side which is widely used where it is required a certain mechanical strength, and thanks to its shape and to its waterproofing not suffer from particular problems in cases where we are in contact with the molten plastic losses.

APPLICATIONS

  • Heating of metals, gases and liquids
  • Heating of molds, flat heads extrusion
  • Air heating
  • Packaging machines, packaging machines

 

QUALITY CHECK

All band heaters for nozzle  are subjected to the test of quality and safety. The tests are performed with automatic machine and comply with all applicable legislation.

  • Brass tubular shell (mod. R16)
  • Steel shell with high thermal conductivity (mod. R14)
  • Resistive winding Nickel-Chromium 80/20
  • Mica insulation continues
  • Flexible power cable bipolar + ground (mod. R16)
  • Bipolar flexible power cord (mod. R14)
  • Conductors in insulated nickel Teflon-glass with temperature protective metal sheath of work max 320 °C with peaks of 350 °C
