INTRODUCTION

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.

APPLICATION
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.

DESIGN
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.
