These Furnaces furnaces include unique insulation and heating element composites to minimize outer surface temperatures while maintaining uniform heat distribution within the chamber.


  • Controlled heat-up rate eliminates thermal shock to materials
  • Quick heat-up and cool-down rates
  • Energy efficient Moldatherm insulation with embedded heating elements
  • Unique double-wall construction minimizes exterior surface temperatures for operator safety and energy efficiency
  • Side-hinge door for convenient operation and full chamber access
  • Long-life Type "K" thermocouple
  • Air vent (1" dia., top) and air inlet (0.375" dia., rear) for inert atmosphere exchange. Will experience some leakage at door
  • Removable and replaceable Moldatherm hearth plate supports load and prevents damage due to spillage
  • Main power on/off switch on control panel
  • Safety door switch to interrupt power to heating element when door is opened; protects heating element and minimizes exposure to end-user

Digital, Single Setpoint Controller

  • Microprocessor-based control with selectable self-tuning feature sets best control parameters for the thermal process. PID control (proportional, integral, derivative) prevents overshoot
  • Single segment, single setpoint, 1 ramp to setpoint
  • Adjustable high limit overtemperature protection
  • Simultaneous LED display of actual temperature vs. setpoint
  • May be configured to display temperature in either °C or °F
  • UL approval
