Versatile selection of chamber box furnaces in several popular chamber sizes to meet  a variety of demanding industrial and laboratory applications

° Unique insulation and heating element composites to minimize outer surface temperatures
    while maintaining uniform heat distribution within the chamber
° Advanced engineering and specialized construction techniques include variable density
    insulation, double shell cabinets, long-life heating elements and horizontal side swing doors
° 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 over-temperature protection
° Simultaneous LED display of actual temperature vs. setpoint (°C or °F)

Advanced Construction

° Advanced 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 (1in. dia., top) and air inlet (0.375in. dia., rear) for inert atmosphere exchange;

     note: door is not gas-tight
° 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
