    Frequently Asked Questions

    Q: How does the air cooler reduce operation noise and vibration?
    A: The panel and side plates are engineered using a step structure. This specific layout effectively minimizes the vibration caused by the fan, resulting in lower operational noise. Additionally, both the water pan and side plates are designed for easy dismantling.
    Q: What treatment is applied to the shell to ensure durability?
    A: The shell undergoes a thorough phosphating treatment followed by a surface spray coating. This process provides excellent corrosion resistance, a smooth surface finish, and a significantly extended product life span.
    Q: How is the air tightness of the air cooler guaranteed?
    A: Every unit is subjected to a strict 2.6MPa air tightness test during manufacturing to ensure it meets all structural and operational air tightness requirements.
    Q: What type of defrosting system is used in these units?
    A: The units utilize electric defrosting with high-insulation stainless steel heating tubes. Their optimized layout ensures short defrost times, high efficiency, and low energy consumption. Users can also integrate an automatic defrosting controller module.
    Q: What are the standard test conditions for SDJ, SDD, and SDL cooling capacities?
    A: SDJ capacity is tested at -25℃ inlet / -31℃ evaporation; SDD at -18℃ inlet / -25℃ evaporation; and SDL at 0℃ inlet / -8℃ evaporation. All capacities are calculated with a refrigerant liquid temperature of 20℃ (30℃ for SDL).
    Q: What cold storage applications are these air coolers suitable for?
    A: They are highly suitable for fruit & vegetable preservation, medical cold storage, flower preservation, red wine storage, aquatic product processing, special testing facilities, and food processing cold storage.
