    Frequently Asked Questions

    Q1: Which refrigerants are compatible with these cooling units?
    These units are highly versatile and compatible with a wide range of refrigerants, including R404A, R507A, R448A, R449A, R134a, R22, and other standard refrigerants.
    Q2: What defrosting methods are supported by the system?
    Electric defrosting is the standard configuration, utilizing stainless heating pipes installed in the middle of the coil and the inner water plate. However, hot gas defrosting or coil hot gas defrosting options can also be accommodated.
    Q3: How are the axial fans designed for optimized performance?
    The fans are designed with a high wind circle and work within a temperature range of -40℃ to 60℃. They feature an integral stretching high air duct design which ensures a better ventilation effect, longer airthrow, and significantly lower noise levels.
    Q4: What are the primary differences between DJ, DD, and DL cooling capacities?
    The models are calculated under different operating conditions: DJ is designed for low-temperature applications (inlet -25℃ / evap -31℃), DD for medium-low temperatures (inlet -18℃ / evap -25℃), and DL for high/medium temperatures (inlet 0℃ / evap -8℃).
    Q5: What materials are used to construct the casing and heat exchanger coil?
    The casing uses a high-quality steel plate finished with a powder coating in RAL9003. The heat exchanger coil is manufactured using Φ12 copper tubing with corrugated aluminum fins, offering optimized heat transfer.
