    Frequently Asked Questions

    How does the air cooler reduce noise and vibration during operation?

    The panel and side plates of the air cooler feature a stepped structural design, which effectively reduces fan operating noise and vibration, ensuring a quieter and more stable operation.

    What measures are taken to prevent corrosion on the equipment shell?

    The equipment shell undergoes a professional phosphating treatment followed by surface spraying processes. This dual treatment delivers excellent corrosion resistance, provides a smooth finish, and extends the overall service life of the product.

    What are the air tightness testing standards for these air coolers?

    All units undergo and pass a strict 2.6MPa air tightness test. This ensures complete compliance with rigorous industry standards for safe and leak-free operation.

    How is the defrosting system optimized for energy efficiency?

    The electric defrosting system is designed with high-insulation stainless steel heating tubes placed in a highly efficient layout. This allows for fast defrosting with minimal power consumption. Additionally, users can install a controller module to automate the defrosting cycle for further energy savings.

    What are the temperature parameters used to determine the DJ, DD, and DL cooling capacities?

    DJ cooling capacity is calculated based on a -25℃ inlet dry-bulb temp, -31℃ evaporation temp, and 20℃ liquid temp. DD is based on -18℃ inlet, -25℃ evaporation, and 20℃ liquid temp. DL is based on 0℃ inlet, -8℃ evaporation, and 30℃ liquid temp.

    Are the units easy to install and maintain on-site?

    Yes. The air coolers are designed with a slotted frame structure to simplify on-site installation. For maintenance, the water pan and side plates are detachable, and all internal wires and plugs are centrally integrated inside the electrical box for easy inspection.
