The shell is made of quality steel plate;sprayed plastic surface is anti-corrosive, and its appearance is handsome 
    Coiled pipes are mechanical expanding tubes instaggered arrangement;therefore, copper tubes and aluminum sheets are combined closely, and ensure good effect of heat exchange, electrical heating tubes made of good stainless steel are distributed evenly in coiled pipes, and thus ensureexcellent defrosting effect.Electrical heating tubes are defrosted by cosely conecting electrical aluminum bushing and holes of fins as a result, heat is dissipated easily, and thus fan boasts long service life 
    The design width of this cooling fan is reasonable, space between fan blade and aluminum fin is larger than 1/3diameter of fan blade in order to ensure sufficient effective air volume 
Long-distance air supply ducts can be used according to customers' requirements
