GENERAL DESCRIPTION:
The insulations used are of the highest quality and are of the latest types available, graded for optimum efficiency to reduce heat losses and enhance a uniform working zone.
ST12 furnaces are constructed with a robust mild steel casing attractively finished in hammer blue paintwork, for bench mounting, and designed with vented double skin construction ensuring that the furnace casing remains relatively cool.
A type N thermocouple probes the furnace tube for accurate measurement and control.
Heating: A hard wearing sillimanite tube forms the furnace chamber with high quality spiraled wire heating elements carefully positioned and fixed in place to produce a uniform hot zone. Power switching to the elements is by means of solid state relays for accuracy and reliability.
Controls: For ease of vision the controls are on one side of the furnace casing, below the furnace body. A microprocessor based digital temperature controller with set-point and process displays, provides accurate fully automatic control. A fully adjustable independent digital over-temperature protection controller with manual reset can be fitted if required. Controls include thermocouple break protection.
Other sizes, as well as vertical tube; multi-tube, and split tube furnaces can be made to order. Single open ended tube furnaces are also available.
