Flooded type water cooled screw chiller

Types of: Screw chiller
Standard cooling capacity: 618KW (kw)
Structure type:Screw type

Flooded type water cooled screw chiller feature：

1. Compact structure, smooth operation: compressor adopting imported high efficient semi-closed double-screw compressor, with compact structure,small volume,  light weight, less installation space advantages. Semi-enclosed twin-screw compressor with fewer moving parts, 5: 6 compressor with ultra-efficient screw rotor, there is no direct wear between the rotor, high reliability. As the screw machine is a continuous compressor pulsation, the unit has the characteristics of stable performance, low noise, small vibration, stable operation. Than the reciprocating compressor efficiency increased by 20% to 30%. Has obtained ISO9001 international quality certification and Europe and the United States multi-national patent.

2. Perfect energy control system: to achieve graded or stepless energy regulation, according to changes in load self-regulation unit start and stop, more energy-efficient. The computer control system will change the unit’s energy output according to the client heat load changes in running time . The microcomputer rapidly determines the signal to push the spool to the desired energy by monitoring the difference between the actual load measured and the user’s setting. And in multi systems, with the best output of the best way to minimize power consumption optimization work, not only at full load to reflect the excellent performance, even in partial load also have high operating efficiency.

3.High efficient patented heat exchanger: water side heat exchanger (condenser, evaporator) with efficient heat transfer tubes, a number of inventions and practical patents, including string-type fluorine water heat exchanger by a number of international patents. The wind side heat exchanger (condenser) adopts high-purity internal thread copper tube and hydrophilic fins, which is formed by mechanical expansion tube and has high heat exchange efficiency. The fan adopts multi-blades and large diameter and low noise type, and the noise is lower than the national environmental protection requirements.

4. The cooling system independent operation: Large-capacity unit has two or more independent refrigeration circuit, even if a circuit failure or maintenance, the other circuit can also be normal operation. Equipped with features, especially for industrial non-stop running.

5.Simple operation: The unit adopts microcomputer controlling, touch screen display (Chinese or English display), according to the menu on the screen to select operation, directly touch the display button on the screen to start the unit. The screen can display the running status of the unit at any time, and displayed in two ways with graphic and text table parameters at a glance. At the same time with fault inquiry, easy maintenance inspection.

6.Multiple protection, safe and reliable: In addition to the compressor internal protection module to provide over-voltage, phase loss, overload and other functions to protect the compressor, at the same time with the compressor coil temperature is too high protection, oil preheating timer switch, Cold water flow switch, cold water temperature is too low protection, Y-r start failure protection, exhaust temperature is too high protection, compressor overload protection, power-down memory function, start and stop frequent protection, voltage abnormal protection, low oil level protection , High and low voltage protection and other protection functions. Make the unit work on the safe side.

7. The cooling unit accessories:  besides the two devices are made domestically, the other parts adopts imported famous brand products with high reliability. The expansion valve, drying filter are the famous brand ALCO and SPORLAN fittings. The quality is stable and high reliability.

8. The application of environmentally friendly refrigerant: You can use a variety of environmentally friendly refrigerants: such as 134a, 404a, etc., to meet the international community environmental requirements.

9. Can choose a variety of secondary refrigerant: According to customer requirements

10. Easy to install: The unit has completed all the parts in the factory installation and operation tests, and has been filled with refrigerant and refrigeration oil, users only need to connect the waterway and the circuit can be put into use, reducing the installation and commissioning time.
