Product brief introduction
Marine direct AHU is a central AHU after several years of continuous technical improvement, carrying the technology security and innovation, the main function is to equip with marine compress-condensing unit and conduct cooling and dehumidification in summer, heating in winter and ventilation 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.
Type demonstration
"TMU"： marine AHU
"320"： nominal cooling capacity is 320kW
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 ventilation 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.
Product advantages
Marine direct AHU sets all functional components in one; it has the advantages of convenient and simple operation, compact structure, low energy consumption, low noise, shock and swing resistance, convenient maintenance etc. The design, manufacture, delivery of AC system is conducted according to the standard of classification societies (such as "CCS", "ABS", "NK","DNV') and "navy", and it can be manufactured according to customer's actual demands.
