    Frequently Asked Questions
    What are the key design features that reduce noise and vibration?

    The panel and side plates of the equipment adopt a stepped structural design. This design effectively minimizes operating noise and vibration caused by the fans, ensuring quieter performance.

    How is the air tightness of the air coolers tested?

    All products undergo a rigorous 2.6MPa air tightness test during manufacturing to ensure complete structural integrity and compliance with strict safety standards.

    What differences exist between the DJ, DD, and DL air cooler series?

    The series are optimized for different temperature ranges: DJ series is designed for low-temperature applications (evaporation at -31℃), DD series for medium-temperature storage (evaporation at -25℃), and DL series for high-temperature preservation (evaporation at -8℃).

    How does the electric defrosting system save energy?

    The defrosting system utilizes high-insulation stainless steel heating tubes positioned in a highly optimized layout for fast heat distribution. Users can also install an optional controller module to enable automated defrosting, which prevents unnecessary heating cycles and lowers energy bills.

    Are the air coolers suitable for harsh or corrosive environments?

    Yes. The equipment shell undergoes professional phosphating treatment followed by a surface spraying process, which provides excellent corrosion resistance and extends the overall service life of the product.

    How is maintenance and wiring managed in these units?

    For easy maintenance, the water pan and side plates feature a detachable structure. Additionally, all internal wires and plugs are centrally integrated inside a single electrical box, simplifying installation, routine inspections, and repairs.
