The "High temperature furnaces" are divided into three classes, i.e. HT up to 1400°C maximum, VH up to 1500°C maximum, and CL models up to 1600°C. 1700°C and 1800°C furnaces are designed to order.
A welded steel furnace chassis is enclosed with coated panels. 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 full width door, of the up and over type, affords obstruction free access to the work chamber and keeps the hot face away from the operator at all times. The door is counterbalanced and a polished stainless steel shelf is fitted below.
The controls are set 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.
