    Frequently Asked Questions (FAQ)

    What design features help reduce the noise of this air cooler?
    The panel and side plates are designed with a step structure, which effectively reduces the noise caused by the fan and its vibration.
    What pressure standard is used for the air tightness test?
    Every unit undergoes a strict 2.6MPa air tightness test to ensure the system satisfies all air tightness requirements.
    How does the copper tube and aluminum fin combination achieve stable heat transfer?
    The aluminum fin and copper tube are combined tightly using a liquid pressure expansion machine, which ensures optimal contact and a stable heat transfer effect.
    Can the electric defrosting system be controlled automatically?
    Yes. The electric defrosting system uses high-insulation stainless steel heating tubes. Users can easily add a module in the controller to achieve automatic defrosting control.
    What are the testing conditions for DJ, DD, and DL cooling capacities?
    - DJ: Dry-bulb temp -25℃, evaporation temp -31℃, refrigerant liquid temp 20℃.
    - DD: Dry-bulb temp -18℃, evaporation temp -25℃, refrigerant liquid temp 20℃.
    - DL: Dry-bulb temp 0℃, evaporation temp -8℃, refrigerant liquid temp 30℃.
