3 FEATURES
3.1 General
D series modular air-cooled scroll chillers are well-developed products incorporated with multiple advanced
technologies. It features the low noise level, compact structure, easy operation, reliable running, and convenient
installation and service, widely used at newly built or retrofitted industrial and civil buildings in various sizes, such
DVKRWHOVDSDUWPHQWVUHVWDXUDQWVRI¿FHEXLOGLQJVVKRSSLQJPDOOVWKHDWHUVJ\PVZRUNVKRSVKRVSLWDOVDQGRWKHU
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.
3.2 Features
D series modular air-cooled scroll chillers work outstandingly by virtue of their major features stated below.
