The 1700°C models are available in three chamber sizes and the 1800°C models in four chamber sizes.

These furnaces are heated by molybdenum disilicide elements — two located on either side of the chamber for the 1700°C models and additional elements at the rear of the chamber for the 1800°C models. The elements provide improved performance and temperature uniformity within the chamber and are suitable for intermittent or continuous operation.

Advanced high temperature hot face insulation is combined with graded low thermal mass insulation to improve energy efficiency and heat up rates; the 1700°C 10 litre model reaches 1600°C in only 44 minutes, whilst the 1800°C 8 litre model reaches 1700°C in only 56 minutes. A low outer case temperature is achieved through fan cooling.

Fitted with 3216P1 programmer and overtemperature protection as standard. RS 232 digitial communication is provided as standard on models HTF 17/5, HTF 17/10, HTF 18/4 and HTF 18/8.

  High temperature furnaces with maximum operating temperatures of 1700 DegC or 1800 DegC
  1700 DegC chamber capacities of 3 or 10 litres
  1800 DegC chamber capacities of 4 or 8 litres
  Powerful MoSi2 elements located on both sides of the chamber ensure good thermal uniformity
  Thick diameter MoSi2 elements can withstand the stress of everyday operation and provide good longevity
  Low thermal mass insulation and good element design is used to ensure energy efficiency and rapid heating
  Manually operated 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
  Double skinned construction allows fanned air flow to cool the outer case, to conform to EN61010 safety standard
