Heat Treatment Pads | Maltec-H Channel Heater: Four Bank, Double & Single Channel

MALTEC-H Channel Heater 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 affected by combined radiation and convection. The heater element is manufactured from 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 traditional ceramic sleeves.

The standard heaters are suitable for heat treatment temperatures up to 750°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 arrange of voltages up to 240V. Standard heaters should deliver a current of 55 amps and unit heaters are designed for arrange of voltages between 30 and 277V. The higher rating permits the connection of the heaters in groups of three to suit3-phase supplies. The heaters may be mounted onto supports for vessel heat treatments or directly to the components as may be suitable. Avoid contaminants (grease, paint, oil and etc) on the metal surface.
