2020 Good Quality High Temperature Furnaces - Nichrome80 wire coil NiCr8020 spiral heating wire for furnace kiln – TANKII Detail:
Spiral electric heating elements consist of cylindrical spirals formed by one or two resistive wires of suitable alloy depending on the application.
Its main features include the inclusion of a nickel-chrome alloy wire heating element and a normalized tension of -230 V.
The usual applications are: industrial dryers, air heaters, stoves, etc.
Moreover, and according to the alloy wire they contain, we can distinguish three types of models:
- M models, with a 20-5 quality and mainly intended for stoves.
- MS models, with a 80-20 quality and useful for all applications.
- MC models, with a 20-5 quality and used in quartz and infrared tubes.
