Casing：
•The box body of 4-way cassette unit is made of high-quality plates, which are sealed and insulated by pasting insulation plates on the periphery. The insulation plates are pasted by overall insulation and seamless splicing to ensure that there is no condensation on the periphery of the box body.

Front Panel：
•The panel of the unit is made of ABS, and the return air outlet is designed with a grille that can be easily pushed away, so that the filter screen can be replaced and cleaned conveniently and quickly. The air outlet electric deflector can adjust the wind direction according to the demand.

Coil：
•The cooling capacity of water and air shall be balanced to ensure the reasonable matching of cooling capacity and air volume.
•Through accurate calculation, the coil can ensure that the performance of the unit can fully meet customer requirements.
•The coil adopts the form of copper tube through fins, which can fully disturb the air to achieve the maximum heat exchange efficiency. Pay attention to the use efficiency of the coil in the coil design, minimize the heat exchange dead angle, and realize the omni-directional heat exchange of the heat exchanger coil.

Fan：
•Single inlet direct connected volute free large wheel diameter centrifugal fan, low speed, fully enclosed rolling bearing three speed motor, no need to add lubricating oil. The base is equipped with damping pad to reduce the running noise. The power line is protected by a special conduit protective sleeve, which makes the operation of the unit more safe and reliable. The motor, fan and copper coil have passed the performance matching test to ensure the efficient operation of the motor.

Condensate Pump:
•The optimal drainage pump shall be configured according to the air volume and cooling capacity, so as to ensure that the condensate of the unit can be discharged well.
