    Frequently Asked Questions

    Q1: What materials are used for the casing of these cooling units?

    A: The casing is made of high-quality steel plate with a powder coating finish in RAL9003. It also features a hinged structure on both side plates and the external drip tray for convenient operation and maintenance.

    Q2: Which refrigerants are compatible with these heat exchanger coils?

    A: The units are highly versatile and can meet the requirements for various refrigerants, including R404A, R507A, R448A, R449A, R134a, and R22.

    Q3: What are the specifications of the fans used in these units?

    A: The units utilize axial fans with high wind circles, operating efficiently in temperatures ranging from -40℃ to 60℃. They feature standard 4-pole motors (fan blade diameters of φ300, φ350, φ400, or φ500) and are individually connected to the junction box.

    Q4: What defrosting methods are supported?

    A: Standard models use electric defrosting with stainless heating pipes installed in the middle of the coil and inner water plate. However, hot gas defrosting or coil hot gas defrosting can also be configured.

    Q5: How are the cooling capacities for DJ, DD, and DL models calculated?

    A: DJ capacity is based on -25℃ inlet air / -31℃ evaporation; DD capacity is based on -18℃ inlet air / -25℃ evaporation; DL capacity is based on 0℃ inlet air / -8℃ evaporation.
