    Frequently Asked Questions

    What testing standard do the air coolers pass to ensure air tightness?
    All our products undergo and pass a rigorous 2.6MPa air tightness test, fully complying with strict industrial air tightness standard requirements to ensure reliable and safe operation.
    How does the stepped structural design help in operation?
    The panel and side plates utilize a stepped structural design, which effectively reduces fan operating noise and vibration. Additionally, the water pan and side plates feature a detachable structure for quick and easy disassembly and cleaning.
    What are the cooling capacity baselines for DJ, DD, and DL models?
    - DJ Model: Based on an air inlet dry-bulb temp of -25℃, evaporation temp of -31℃, and refrigerant liquid temp of 20℃.
    - DD Model: Based on an air inlet dry-bulb temp of -18℃, evaporation temp of -25℃, and refrigerant liquid temp of 20℃.
    - DL Model: Based on an air inlet dry-bulb temp of 0℃, evaporation temp of -8℃, and refrigerant liquid temp of 30℃.
    How is the defrosting system designed for efficiency?
    The electric defrosting system uses high-insulation stainless steel heating tubes laid out for fast, high-efficiency, and low-power defrosting. Users can also install an optional controller module to enable automatic defrosting control, optimizing efficiency and lowering energy costs.
    What measures ensure the durability and corrosion resistance of the shell?
    The equipment shell undergoes professional phosphating treatment and surface spraying processes. This provides excellent corrosion resistance, a smooth finish, and extends the overall service life of the product.
    How are the internal copper tubes prepared for stable performance?
    We adopt an automatic forming process that keeps the inner wall of the copper tubes dry, clean, and completely free of impurities, ensuring stable operating performance.
