2. Features
Leading technology of twin screw compressor
Midea screw chiller is equipped with the 3rd generation industrial
compressor that has the latest advanced 5-6 asymmetry dentiform
semi-hermetic screw rotors.
The rotors are processed by high-precision CNC and each part is
well-proportioned and none-gap matched, which minimizes the friction
resistance and clearance lost and also guarantees quiet running and
good duration.
High efficiency, energy saving
Extremely high full load and partial load energy efficiency.
New twin-rotor screw compressor equipped with a high-efficiency motor and a variable capacity
valve that can adjust the capacity of 25%, 50%, 75% and 100% in 4 stages (Stepless control as an
option) and permits exact matching of the cooling capacity to the actual load.
A decrease in chiller energy costs, particularly at the part-load conditions at which the chiller
operates most of the time.
Outstanding reliability
Full factory testing of the unit with water hookup helps provides a trouble-free start-up.
Extensive quality control checks during testing means that each equipment protection and operating
control is properly adjusted and operates correctly before it leaves the factory.
Transport simulation test in the laboratory on a vibrating table.
Factory-installed options minimize field expenses and startup labor.
Intelligent control, easy operation
Microprocessor control as standard on all the units. A display
illustrates the machine’s operation status and programmable
parameters (set point) e.g. water temperature and refrigeration
pressure and temperature, allowing the operator to determine the
unit status and also allow changes to various set points. The control
system adopts PCB with predictive logic to select the most energy efficient combination of
compressors.
Easy and fast installation
The unit has passed full factory test before being delivered to ensure the reliable working on the
site. The unit can be placed in service only after being connected with power and water supply
during field installation.
