Features
Superior
Performance
•
Extensive research work coupled with world leading manufacturing technology has caused 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. Dedicated water pump particularly designed for air
conditioning engineering is operating steadily with minimum vibration and noise.
For MAC080C/CR to MAC150C/CR
•
These units are designed with double independent refrigerating system, greater energy saving is
achieved by only one compressor on duty under part load condition.
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 friendly installation 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.
•
Water inlet and outlet are provided on both sides of the machine such that piping can be connected on
either side of the machine.
•
Rust resistant PP-R composite water pipe with good insulation property and high durability is standard
parts in the machine.
•
Stainless steel taper threaded fittings target convenient disassembly or assembly.
•
For MAC080C/CR to MAC150C/CR, expansion chamber, water pump and water flow switches are
already equipped in this compact packaged unit with top air discharge. 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. For
MAC030C/CR to MAC070C/CR, expansion chamber is equipped in the accessory hydraulic kit instead
of being incorporated in unit.
For MAC030C/CR to MAC070C/CR
•
Both front and rear sides can be served as access to performing wiring and maintenance.
Safety Control
•
Protection devices such as dual pressure protection and overload protection etc. is provided to ensure
unit operating within safety condition range. The microprocessor-based controller automatically directs
system on or off by processing the water temperature feedback. If the water temperature falls to
unacceptable low point, the controller automatically shut off the system to prevent hydraulic system
internal freeze for unit safety operation. Meanwhile, the microprocessor-based controller automatically
monitors every component operating status and malfunction, and feedback it to indoor controller to
greatly ease the work of status monitor and troubleshooting.
All Weather
•
The cabinet is made of electro galvanized mild steel sheet, coated with baked polyester power to ensure
the units extra durability in all climates against sun, rain, wind corrosion.
•
Space saving (small footprint) design of the machine eliminates large installation area requirement, no
need for equipment room.
•
The machine uses high quality parts to ensure durability in various climate conditions.
