Main components:
It is mainly composed of air handling unit(fin type evaporator, heater and humidifier), air supply section(centrifugal fan and marine motor), mixing and filtering section(mixing box, fresh and return air regulation valve, air filter), electric control unit, the structure type is frame structure, suction type, all parts are installed on a base.

Protect function:
The main function of marine direct AHU is to conduct cooling and dehumidification in summer, conduct heating in winter and valtilation in middle seasons. This AHU completes all heat and humidity exchange in plant, the treated air is delivered to each cabin through air duct, terminal units.

Advantages:
Marine direct AHU sets all functional componets in one; it has the advantages of convenient and simple operation, compact structure, stable performance, low energy consumption, low noise, shock and swing resistance, convenient maintenance etc.
