    Frequently Asked Questions

    What types of refrigerants do these cooling units support?
    These units are highly versatile and can meet the operating requirements of various refrigerants, including R404A, R507A, R448A, R449A, R134a, R22, and other standard options.
    What are the specifications of the heat exchanger coils?
    The heat exchanger coils are constructed with copper tubing of Φ12 diameter and a spacing of 38.1x33. They feature corrugated aluminum fins with variable fin spacing options of 4.2mm, 6.4mm, and 9.0mm to suit different cooling applications.
    What defrosting methods are supported by the system?
    Electric defrosting is the standard configuration, featuring stainless steel heating pipes installed in the middle of the coil and the inner water plate, paired with an independent electric heating tube junction box. Alternatively, hot gas defrosting or coil hot gas defrosting can be integrated.
    What are the characteristics of the axial flow fans?
    The axial flow fans are equipped with a high wind circle and have a working temperature range of -40℃ to 60℃. They feature an integral stretching high air duct design for improved ventilation, longer airthrow, and reduced noise. Fans are individually wired to a junction box and are available in φ300, φ350, φ400, and φ500 blade sizes with standard 4-pole motors.
    How are the cooling capacities of the DJ, DD, and DL series calculated?
    The cooling capacity is calculated based on specific design conditions:
    • DJ Series: Air inlet dry-bulb temp of -25℃, evaporation temp of -31℃, and refrigerant liquid temp of 20℃.
    • DD Series: Air inlet dry-bulb temp of -18℃, evaporation temp of -25℃, and refrigerant liquid temp of 20℃.
    • DL Series: Air inlet dry-bulb temp of 0℃, evaporation temp of -8℃, and refrigerant liquid temp of 30℃.
    What is special about the casing structure?
    The casing uses a high-quality steel plate finished with a RAL9003 powder coating. For convenient and fast maintenance operations, a hinged structure is adopted for both the side plates and the external drip tray.
