    Microprocessor-Based Control

    • Selectable self-tuning feature sets best control parameters for the thermal process
    • PID control (proportional, integral, derivative) prevents overshoot
    • Main power ON/OFF switch on control panel
    • Controlled heat-up rate eliminates thermal shock to materials
    • Quick heat-up and cool-down rates
    • Adjustable high-limit overtemperature protection
    • Simultaneous LED display of actual temperature vs. setpoint
    • Can be configured to display temperature in either °C or °F


    • Unique double wall 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 in. dia., top) and air inlet (0.375 in. 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
    • Energy-efficient Moldatherm insulation with embedded heating elements
    • 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

    • Single segment, single setpoint, one ramp to setpoint

    Digital Single-Program, Multiple-Segment Programmable Controller

    • Single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control

    Ordering Information:

    Optional RS485 Digital Communications Port allows controller to be connected to a PC for remote monitoring and control of the furnace. Up to 30 units can be connected to one PC.


    10 ft. power cord except 1.5 cu. ft. models which require customer-supplied power cord or hardwiring.
