Mica Insulated Heaters

These heaters can be supplied as flat or band heaters. The flat heaters can be supplied as bare mica heaters or metal sheathed in Zintec. The sheathed heaters can also be formed to shapes such as 'L' or 'U' sections. Please consult us for your specific requirements.

Flat mica heaters can be supplied with holes and cut outs to customer design. Flat mica heaters must be securely clamped to the surface to be heated.

Mica band heaters can be supplied in single or multiple units to fit almost any diameter of barrel, drum, die etc. Fixing is by integral clamping bracket or separate clamp band with barrel nuts. As with flat mica heaters, band heaters can be designed with holes and
cut outs to suit customer requirements.

For both flat mica and band heaters, the heating element is constructed by winding a high temperature resistance tape around a mica former. This is then insulated with mica sheets and is termed as a bare mica heater (terminations added). For flat sheathed, formed or band heaters, this assembly is then encased in Zintec sheet to give a robust mechanical protection to the element and allow it to be formed to various shapes.

Standard termination is by high temperature leads but options such as screw terminals, terminal box, 2-pin plug etc, are available.

Flat mica and flat sheathed heaters can be manufactured to almost any size. The limiting factors being the design of a suitable element tape and on large heaters, the ability to provide adequate clamping over a large surface area. Band heaters are manufactured in one-piece construction up to 12" diameter. Sizes over this can be accommodated by combining two or more heaters around the diameter.
