  • Model:BN-QS Series
  • Description

    BN-QS Series Three - zone Thermal shock testing chamber exposes products to alternating low and high temperatures to accelerate failures caused by temperature cycles or thermal shocks during normal use. The transition between temperature extremes occurs very rapidly.

    And thermal shock testing is different from thermal cycling, the latter being a longer and slower process.

    Product Features
    Three - zone separation thermal shock chamber design: low, ambient and high temperature 
    Cascade refrigeration system with semi-hermetic compressor and CFC free refrigerant
    Adopts unique cool storage and heat storage technology and specimen placed still in test zone
    Uses world famous core components ensuring high efficient and reliable performance
    7 inch TFT true color LCD touch screen is more bigger than other screens, is more intuitive, simpler, bigger, more stable and more energy-efficient than other screens
    Modular refrigeration unit to ensure manufacturing quality and convenient replacement and maintenance
    Multiple safety protection measures include failure alarm indication and display of failure cause and troubleshooting
    Sound sealing performance
    Using advanced automatic defrosting technology effectively cuts defrosting time and improves machine's efficiency
    Complete hermetic compressor, CFC free refrigerant, plate heat exchanger and cascade ultra-low temperature refrigeration system 
    Optional PC remote monitoring computer and software implementation of redundant design can be connected to PC computer and touch screen controller
