    Frequently Asked Questions

    What types of refrigerants are compatible with these cooling units?
    These units are highly versatile and designed to meet the requirements of multiple common refrigerants, including R404A, R507A, R448A, R449A, R134a, and R22.
    What defrosting configurations are available?
    Electric defrosting is the standard configuration, featuring stainless steel heating pipes installed in the middle of the coil and the inner water plate, with an independent junction box. Hot gas defrosting or coil hot gas defrosting can also be configured upon request.
    What are the specifications of the casing?
    The casing uses high-quality steel plates finished with a protective RAL9003 powder coating. For easy maintenance, both the side plates and the external drip tray feature a hinged structure.
    What are the differences between DJ, DD, and DL cooling capacities?
    Each capacity rating is calculated based on specific temperature parameters:
    DJ Capacity: Air inlet dry-bulb -25℃, evaporation -31℃, liquid refrigerant 20℃.
    DD Capacity: Air inlet dry-bulb -18℃, evaporation -25℃, liquid refrigerant 20℃.
    DL Capacity: Air inlet dry-bulb 0℃, evaporation -8℃, liquid refrigerant 30℃.
    What are the working conditions and features of the fan motors?
    The units are equipped with axial fans with an integral stretching design that improves ventilation and airthrow while reducing noise. They operate reliably within a temperature range of -40℃ to 60℃ and are individually connected to a dedicated junction box. Standard 4-pole motors are available with fan blade diameters of φ300, φ350, φ400, and φ500.
