The range of channel elements has been designed to provide modular heating units of a robust design suitable for connection to a mains or low voltage
electrical supply. The heaters are portable and solid and are suitable for use in temporary furnace design or for the heat treatment of pressure vessel
welds and sections, or other large fabrications. Heat transfer to the component is effected by combined radiation and convection.

Standard heaters should deliver a current of 55amps and unit heaters are designed for a range of voltages between 30 and 277V. The higher rating permits

 the connection of the heaters in groups of three to suit 3-phase supplies. The heaters may be mounted on to supports (such as shown in the layout which 

follows) for vessel heat treatments or directly to the components as may be suitable. Avoid contaminants (grease, paint, oil etc) on the metal surface.

The heater element is manufactured from solid drawn 9swg Kanthal or nickel-chromium coiled wire. The coil may be embedded into a high conductivity cast

 refractory material within each of the unit stainless channels trays that form the heater. Alternatively the heaters can be manufactured with the traditional

ceramic sleeves. The standard heaters are suitable for heat treatment temperatures up to 800°C. Temperatures above this value can be achieved by variation

 of the composition of the case/coiled wire and heater design. Standard heaters are supplied for a range of voltages up to 240V.
