ST 12 - Tube furnace range
1200°C maximum operating temperature

•   Choice of standard sizes   •   Safe, simple and economical to use   •   Automatic digital control with indication   •   High efficiency, low thermal mass insulation   •   Over temperature protection option

GENERAL DESCRIPTION:

Tube furnaces are available for a wide range of operating temperatures. Up to 1200°C they are wire wound.

All the furnaces have an inner "heat box" surrounded by an air gap set in a steel mesh outer casing.

The furnace work tube in the ST12 range of furnaces consists of a suitable dense ceramic tube on which high quality spiralled wire elements are carefully positioned to produce a uniform hot zone. A graded back-up of ceramic fibre materials provides the insulation between this tube and the metal work box. The furnace ends are made from heat resisting ceramic material.

A sheathed thermocouple within the chamber (or in contact with the work tube in the ST12 series) gives accurate temperature sensing.

The controls are on the front below the furnace "heat box" and consist of a green illuminating push button on/off switch, an orange "load on" neon, and a red thermal cut-out neon (when fitted with the over-temperature control option). PID solid state, fully automatic temperature controllers are fitted, incorporating thermocouple break protection as standard.

A choice of PID digital controllers with digital setting and readout are offered.

Power supply is 230V 50 Hz single phase unless otherwise requested .
