Description
Metal band heaters are one kind of band heaters that are applied to heat extruders, molds, molds, granulators and other industrial equipment. The heating element is a resistive tape insulated with a layer of heat-resistant micanite. The body of the heater is made of stainless sheet steel.
Additional manufacturing options:
- Cutouts and/or holes.
- The ring heater can be equipped with a thermocouple to control the surface temperature or a place to install it.
It should be remembered that a metal annular heater is a contact type electric heater, therefore, for long and efficient operation of the heater, it is necessary to ensure close contact between the heating part of the heater and the heated surface. This can be achieved with mounting paste.
Before installation and operation, it is recommended to read the instruction manual for electric ring heaters.
To improve thermal conductivity and troubleshoot operation, you must ensure that the heating element is in even contact with the heated surface thanks to Gripcott NF high temperature paste, which will eliminate small bumps and fill voids.

Installation
- Installation of electric heaters to the heated material of the object must be carried out using mounting hardware (studs, bolts, clamps, clamps, brackets, ties). Note: After the first switching on of the electric heater after 30 – 45 min. fasteners must be tightened.
- It is not allowed to fasten heaters by contact leads.
- During installation, it should be taken into account that the electric heaters during operation should not come into contact with each other, the minimum allowable distance between the electric heaters is 5 mm.
- Installation of electric heaters should be carried out in such a way that the active part of the heater is in close contact with the material of the object.
- All live parts must be protected from accidental contact and moisture.
In order to quickly detect the failure of any heater, it is advisable to connect the heaters to the network through individual fuses. - The connection of the electric heater must be made through means of automatic shutdown in emergency mode or through individual fuse-links, excluding fire in case of overload and short circuit in the power circuit.
- All installation and dismantling work must be carried out with the voltage removed.
