marine type packaged air conditioner Application:
 
It is mainly applied to hotel, factories, schools, auditoriums, warehouses, etc.
 
marine type packaged air conditioner Features:
1. Air cooled rooftop ac is applied to dry areas.
2. This rooftop ac is with compact structure, installed on the roof, convenient for installation, occupy no indoor space.
3. Sufficient external static pressure, suitable for connecting air duct system, reduce indoor noise greatly.
4. Different series of rooftop ac, meet different requirements.
5. The framework of this air cooled rooftop ac is anti-cold bridge aluminum alloy, which eliminates cooling leakage and condensate water due to large temperature difference between inside and outside.
6. The main parts of this rooftop ac are imported quality products, with excellent performance.
7. The evaporator and condenser adopts technology of enhancing heat transfer, which makes the exchanger high efficiency and save energy.
 
marine type packaged air conditioner Structure:
