Details

  • Temperature Humidity Test Chamber

    Inner Chamber

    Outer wall: 1.5mm cold-rolled steel plate with plastic-sprayed surface;

    Insulation layer: 100mm polyurethane foam + ultra-fine glass wool, to ensure that the outer surface of the test box does not frost and dew;

    Inner wall: 1.2mmSUS304 # stainless steel plate;

  • Control system

    7 ”TFT color touch screen controller

    P.I.D control parameters: 9 sets of PID control parameters are automatically calculated

    Screen functions Touch input, display temperature and humidity set value and measured value, display various parameters of program operation, operation timing, display equipment operation curve and history curve, Chinese and English interface optional, fault prompt screen, screen backlight adjustable.

    Refrigeration System

    Mechanical compression refrigeration;

    Compressor starts at the suitable time, reducing the compressor starting current and reducing the interference to the power grid;

    The controller + solenoid valve on and off to control the refrigerant flow for cold balance control;

    No cooling during heating, no heating during cooling, because the cooling balance method can reduce the consumption of compressor and heating system, and theoretically can save 20% or more energy at low temperature;

  • Humidity System

    Water circuit separation to ensure safety

    Safety System

    1 over temperature alarm

    2 leakage protection

    3 over current protection

    4 lack of phase protection

    5 overpressure protection

    6 grounding protection

    7 water shortage protection

    8 gas shortage protection

  • Electrical System

    Wiring neatly, all components with a label to show its function
