MCAC-ATSM-2017-08 Aqua Tempo Power Series (with LAK) air cooled scroll chiller unit (50Hz)
3
2 Features
1). Low ambient temperature cooling function
the ambient temperature is down to -10 in cooling mode with low ambient kit this function should be
activated by S8 switch on the PCB board.
Mode Ambient temp.
Cooling
Normally S8 address OFF 10~46
Low temp. (S8 address ON) -10~46
2). Wide range of outlet water temperature
Cooling: 5~17˚C (Set in factory), 0~17˚C can be available by switch the S5 on PCB, the antifreeze must be
put into water system.
Heating: 40~50˚C (Set in factory), 22~50˚C can be available by switch the address.
Mode Outlet water temp.

3).Digital scroll technique
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. Digital scroll technique, provide maximum reliability,
high efficiency and quiet operation.
4).Modular design, flexible combination
The unit adopts modular design, which can make more units to connect together. The unit can be combined
max16 modules (30&65kW module),5 modules (200kW module) or 8 modules (130&250kW
module),meanwhile every separate module can be operated as main unit, also each module can be a slave
unit with modules combination(The digital unit must be operated as main unit if the system has digital unit.),
more convenient for design and installation.
5).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 wire.
