PRODUCTS - Open Coil Air Heater


IH open coil air heater consist of an Nickel chromium spiralled resistance wire mounted into, an insulated from a metal frame , by high temperature ceramic bushes . The rating of this wire will depend upon application (i.e.) black heat for ducted air heating and red heat for a radiant application.

This type of construction gives a source of heat with accurate temperature control. There is no tendency to overshoot or undershoot because of the low mass of the heating spiral with which heat rapidly when the circuit is made and cools quickly when the circuit is broken.
