These furnaces offer the large capacity and robust construction required for general workshop use, together with the performance capabilities and case style of the smaller laboratory models.

Traditional hard wearing refractory materials used for the chamber entrance and hearth plate provide good resistance to accidental damage and a solid support for hevier furnace loads.

Free radiating coiled wire elements supported in open grooves, together with low thermal mass insulation, typically power these furnaces to working temperature in approximately 40 minutes, and provide efficient and reliable operation.

Removable instrument and back panels allow good service access to the case interior, whilst heating element coils are easily and quickly replaced through the door opening.

Chamber sizes are 36 and 65 litres, with maximum temperatures of 1200°C and 1300°C.

  Maximum operating temperatures of 1200 DegC or 1300 DegC
  Chamber capacities of 36, 65, 131 and 200 litres (200 litre 1200°C only)
  Powerful free radiating coiled wire elements on both sides of the chamber ensure good thermal uniformity
  Hard wearing refractory insulation inside chamber and around the entrance provides good resistance to abrasion
  Hard ceramic hearth provides robust base
  Vertical counter-balanced door keeps hot door insulation away from operator
  Postive break door safety switch isolates chamber from power supply, when the door is opened
