The "High temperature furnaces" are divided into three classes in standard front opening format i.e. HT up to 1400°C maximum, VH up to 1500°C maximum, and CL models up to 1600°C.
The basic chamber layout is maintained when the access is moved from front to base.
A welded steel furnace chassis is enclosed with coloured panels and mounted in a frame containing the hearth lifting device and power pack. The hearth lift is provided by a foot operated hydraulic jack with controlled descent release valve.
An air gap with thermostatically controlled cooling fans between the outer panels and the furnace chamber lining ensures that the casing remains relatively cool. The furnace lining is graded high quality refractory insulation material. A thin wall of refractory brick may be included to provide a damage resistant surface and a hard wearing removable tile forms the furnace hearth.
The heating elements are silicon carbide rods mounted transversely in a cavity above the work chamber. The element connections are forced cooled for long life.
The controls are set in the cabinet below the furnace chamber. The controls consist of a green illuminating on/off switch, a green mains neon; an orange load neon, and a red over-temperature warning neon. PID solid state, fully automatic temperature controllers are fitted, incorporating thermocouple break protection as standard.
The PID controllers have digital temperature set point and readout displays with thyristor power switching. Over-temperature protection and a door safety switch are fitted to all models.
