Designed for safety and ease of loading and unloading from the furnace chamber. Larger versions can be made to order.

The furnace is for floor mounting and constructed using a robust welded framework finished in black with coloured panels. A ventilated double skin construction ensures that the furnace casing remains relatively cool. The furnace lining consists of high efficiency graded low thermal insulation material with a hard wearing removable hearth tile.

The vertically lifting hearth is moved in and out of the work chamber by a foot operated jacking system, or as an option, by a push button electrically operated lifting system.

Heating: The heating elements are silicon carbide rods mounted vertically and symmetrically in a cavity around the work chamber. The element connections are forced cooled for extended life. Heating elements can be quickly and easily replaced should this become necessary. Power to the heating elements is controlled by solid state relays for accuracy and reliability.

Controls: The controls are in the cabinet below the furnace chamber and set an angle for ease of vision. A microprocessor based digital temperature controller with set-point and process displays, provides accurate fully automatic control. An adjustable independent digital over-temperature controller is fitted as standard. Controls include thermocouple break protection.
