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. Dedicated water pump particularly designed for air conditioning engineering is operating steadily
with minimum vibration and noise.
M4AC080C/CR To M4AC150C/CR
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 M4AC080C/CR to M4AC150C/CR, expansion chamber, water pump and water flow switch are already equipped in
this compact packaged unit with top air discharge. 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.
Simple To Maintain
The simple design of the machine allows for maximum serviceability. All components are with reach of the maintenance
personnel upon open up of the servicing panel. If emergency shutoff occurs, the microprocessor-based controller will
indicates the fault cause to quicken and ease troubleshooting.
