1. The housing is in plastic-sprayed coat or rolled, iron plate or aluminum paned, best in corrosion protection, beautiful in shape.

2. Original coil arrangement to reduce the side resistance. The aluminum fins are fastened to the steel tubes by hydraulic expanding way, which is effective to reduce thermal contact resistance and improve thermal transfer.

3. After pressure test, wash with trichlorethylene to clean oil dirt, moisture, oxide and other impurities inside. As such, no blocking trouble after filling refrigerant in use.

4. Special fan motor, which is low in power consumption, large in air volume, low in noise, and far in air throw, guarantees good performance in humidity and low temp.

5. Equipped with U-shaped electro-thermal tube，that is good-in insulation inside the coil, rational gap arrangement and power ability to achieve defrosting performance.

6. Groove-type channel clip, easy to install.

7. Filled with nitrogen before leaving factory.
