Superior Performance
Extensive research work coupled with world leading manufacturing technology has resulted the new
design with superb performance and high efficiency.
Stringent quality control and component selection ensure performance and reliability. Major components
are rigorously tested and qualified prior to usage in the machine.
Every machine design has passed many hours of rigorous testing to ensure the machine reliability,
durability and quality.
Scroll compressor brings much higher energy efficiency. High efficiency heat exchanger ensures
strenuous exertion of equipment capacity. Water pump particularly designed for air conditioning
engineering is operating steadily with minimum vibration and noise.
These units are designed with double independent refrigerating system, greater energy saving is
achieved by only one compressor on duty under part load condition.
Robust Construction with Slim Outlook
Detailed engineering work coupled with extensive market research has resulted the new MAC model
come in new mono-block design to yield a compact and robust structure while maintaining the slim
outlook. The smaller capacity models MAC060D4 are having side discharge design, while the larger
capacity models MAC090/120D4 are having top discharge design.
Simple to Operate
The machine is complete with intelligent microprocessor controller and temperature sensor to
automatically control the operation to its optimum condition, making it very simple to operate. All
temperature settings are finished before shipment. The only thing for user to do is to start the unit by
pressing the ON/OFF button after ensuring unit proper function, then every operation can be
automatically performed by the unit itself.
Either wireless remote controller or wired remote controller is ready for choosing to meet satisfactory
indoor unit control, both compatible with the unit.
Friendly Installation
The machine has been designed with installation friendly in mind such that no refrigeration charging or
copper pipe brazing is required on site.
Threaded fitting is provided for easy water piping connection on site.
Taper threaded fittings target convenient disassembly or assembly.
Expansion chamber, water pump and water pressure differential switch is already equipped in this
compact packaged unit. In addition, McQuay provides accessory hydraulic kit with water storage tank,
auto water fill valve, auto air vent valve, auto pressure relief valve and strainer integrated in, aiming at
ensuring high efficiency and safe operation.
