●Performance *:

★Twin screw refrigeration unitThe host adopts a semi enclosed screw compressor, motor, and integrated compressor, without any concerns about shaft seal leakage:

★ Dual or multiple compressors have a start stop cycle control program, and the water-cooled screw chiller balances the load and extends the lifespan of each component

★When two or more compressors use multiple refrigeration circuits, and one circuit requires maintenance, the other circuits can still operate normally, Equipped with backup function:

★ The compressor adopts unloading and voltage reduction starting to avoid impact on the power grid.

●Easy installation:

★ Compact structure, small footprint, saving data center space:

★At the time of leaving the factory, strict debugging and calibration have been completed, and it has reached the on-site use state

★ Small vibration, no need for isolation measures for the foundation, simple installation:

★During installation, only connect the evaporator chilled water and condenser cooling water pipes.

◆Low operation and maintenance costs

★Intelligent program control can be implemented according to the demand of the load:*、75%、50%、25%(or activated)0Save energy consumption;

★The total number of parts for screw compressors is only reciprocating1／1 0The structure is simple, with few vulnerable parts, no intake or exhaust valves, insensitive to humidity travel, and extremely low failure rate;

★Screw compressor * can operate up to4Ten thousand hours

●Complete security protection functions:

★Pressure protection: High voltage protection and low voltage electrical automatic protection devices:

★ Motor protection: undervoltage protection, phase loss protection, reverse phase protection, overload protection, motor overheating protection,

★Oil shortage protection:-Antifreeze protection: When the temperature of the chilled water is too low, Automatic shutdown:

★Safety valve protection: When the refrigerant pressure exceeds a certain value, the safety exhaust valve will automatically open. The various protections of the above equipment ensure the safe and stable operation of the water-cooled screw chiller.

●Characteristics of screw compressor:

★Adopting high-efficiency fluorine resistant motors imported from France, with high efficiency and excellent reliability;

★the third generation5-6Asymmetric tooth shape;

★ Four stage capacity adjustment continuous unloading capacity control system;

★Supporting GermanyFAGAnd SwedenSKFHigh precision bearings;

★Swat effect oil separator;

★Low vibration and low noise.

●Group microcomputer control

★Germany“SIEMENS”PLCProgrammable touch controller, Full Chinese display of human-machine interface: Italy“CAREL”Text display;

★ Automatic monitoring of cold water outlet temperature, throughPLCAutomatically control the slide valve, adjust the compressor, and effectively track the on-site usage load;

★The display screen is intuitive and clear, directly showing the various water temperature points and running time during operation, making it easy to understand at a glance(PLC)；

★ Automatically record and save the fault alarm situation and occurrence time of the nearest water-cooled screw chiller, and issue fault handling prompts;

★Revise the original content according to actual needs (with password). Such as the inlet and outlet water temperature and the location of the volume adjustment, Each protection point, pressure, etc.

●Operation status display(PLC)

★Animation display The operating status includes compressor operation, refrigerant flow condition, water flow condition, and temperature display;

★Convenient and comprehensive understanding The operational status.

●Refrigeration components/electrical components.

★ The electrical control system and refrigeration system used include relays, thermal protectors, expansion valves, and pressure controllers;

★The main components such as drying and filtering are all world-class products, which greatly improves the reliability of the entire machine.
