places where there are high requirements on noise level and air quality but it is troublesome to install the cooling tower.
D series modular air-cooled scroll chillers are constructed of one or up to 16 single units which may vary in
structure and in cooling capacity. The 65, 80 units have two independent refrigeration cycle and the 130,160 units have
four. The modular design is able to realize the modular system with the cooling capacity ranging from 60 to 1160kW.
