R410a tropical air-cooled scroll chiller unit 60Hz MCAC-ATSM-2014-09
1.4 Features
1).Digital scroll technique，new type air-cooled scroll chiller system.
Capacity output is controlled depending on controlling compressor to on/off in traditional modular air-cooled
chiller system control. The precise control mode is not perfect, and the compressor is frequently on and off,
which is very bad for the compressor’s long-life performance.
Digital scroll modular air-cooled chiller system breaks traditional design, which is inconceivably designed with
digital scroll compressor and constant scroll compressor parallel connection. The system can achieve linear
capacity output within1%-100% after modules combined, the scope is widest in industry. When the system
operates at the part-load, the system can accurately adjust cooling and heating capacity output basing on
actual requirement of the indoor room.
2). Easy and fast installation
The unit adopts modular design, which can make more units connect together. The unit can combine 16
separate module(equal and less than 60kw) or 8 module(120kw).Cooling(heating) capacity can increase step
by step by 5kW per each time within 25kW-960kW,meanwhile each separate module can operate as main
unit, also each module can be a slave unit in modules combination, more convenient for design and
installation.
The maximum combination of the system consists of 1 main unit and 15 slave units for 25kw&30kw&60kw
module，1 main unit and 7 slave units for 120kw module, 1 main unit and 4 slave units for 180kw module.
Easy connection between main unit and slave units.
All the units can be connected together with a wired controller in series type. Using three-core shielded
twisted wire as communication signal wire.

3).Environmental care
Ecological R410A refrigerant.
Chlorine-free and environmental friendly refrigerant, zero ozone depletion potential.
High density refrigerant, therefore, less refrigerant required.
