Structural design:
•Air Handling Unit adopts aluminum alloy composite frame structure, and the frame is closely connected with high-strength nylon as tee, with continuous and flat surface and clear and smooth appearance. The unit adopts sheet metal base with galvanized surface.

Panel：
•The box plate is a double-layer sandwich structure. The inner and outer panels are made of hot-dip galvanized steel plate, and other materials such as stainless steel can also be selected according to customer requirements.

Coil：
•The punching machine uses European imported self-evaporating flake oil to make the aluminum sheet automatically form a protective film to resist corrosion and reduce the residence time of the condensed water on the surface of the aluminum sheet, increasing the heat exchange efficiency of the coil, and reducing the wind resistance.
•The heat exchange coil adopts computer programming automation optimization design, and adopts different internal processes according to different flow rates, temperature differences and working conditions, so that the heat exchange performance of the coil and the water pressure loss of the coil are kept within a reasonable and efficient range which reduces engineering application difficulty.
•The coil is made of seamless copper tubes and aluminum fins.Hydrophilic aluminum sheet is optional.
•Adopting high quality copper tube. With 4/6/8-row cold water coil and 1/2-row hot water coil available.
•The copper tubes wear the fin as a whole and are mechanically expanded to aluminum fins tightly to minimize thermal resistance.

Fan & motor:
•Centrifugal fan with external rotor, belt-driver or direct-driver.
•Motor is three-phase asynchronous motor with good quality, IP54 protection and class F insulation.
