Product Description

Detail: high pressure protection high efficiency 1600kw water cooled flooded screw water chiller

for central air conditioning
optional refrigerant, power supply
COP could reach 5.45
flooded evaporator, high efficiency

Superior Performance
1.The main International advanced semi-closed screw compressor in which electric motor and compressor are organically integrated to ensure no leakage of the shaft sealing.

2.The control programs for start and stoppage are applied to double or multiple compressors so as to balance the load and extend the service life of each component.

3.High efficiency flooded evaporator, adopt the electric expansion valve and energy saving hole plate to adjust the flow rate of the refrigerant and the liquid position change of the evaporator.

4.The first and second oil separation with the combine of machinery and the adsorption give the more assurance of the back oil.

5.Several refrigeration circuits are provided for double or more compressors. When one circuit needs maintenance, other circuits can work properly as alternative circuits.

6.The compressor is started with unloading and decompression to avoid the impact to the power grid.

7.With low noise, little libration. To protect the environment, we also supply the R407c or R134a type of refrigerant.

Comprehensive Security Protection

1.Pressure Protection: high pressure protection and low pressure protection

2.Electric Motor Protection: lost voltage protection, incomplete phase protection, reverse phase protection ,overload protection overheating protection

3.Anti-freezing Protection: the unit shall be stopped when the freezing water temperature is too low.

4.Safety Valve Protection: when the refrigerant pressure exceeds the given value, the safety relief valve will be automatically started.

5.All the aforementioned protection can ensure the unit a safe and stable operation.

Low Cost for Operation and Maintenance

1.Adopt high performance screw compressor and newly high efficiency heat exchanger, full load energy-efficiency rate can reach 5.45, this will make the cost much lower.

2.The unit can be controlled by intelligentized program in accordance with the needs of the load. 100%,75%, 50%, 25% (start up), 0. or 10%~100% without class control. By so doing, the energy can be saved.

3.The number of all components of screw compressor is 10% of the reciprocating compressor. The former is structurally simple, with fewer vulnerable components. Besides, it is not equipped with inlet and outlet valve and is of extremely low failure rate due to its low insensitivity to humidity itinerary.

4.The screw compressor can run for 40,000 hours without any failure.

The feature of Screw Compressor

1.Low speed directly driving, only three parts running, Fluorine-resistant electric motor of high efficiency and reliability imported from France

2.The latest 5-6 asymmetrical gear form of the third generation

3.Four-section volume control or no section control continuous capacity adjustment unloading control system, no asthma libration,

4.Equipped with German FAG and Swedish SKF high-precision bearing

5.Shiwoer effect oil separator

6.Low vibration and noise

Microcomputer Control

1.German SIEMENS PLC, human interface with whole Chinese character display; Italian CareL text indicator.

2.Automatically monitor the outlet temperature of freezing water and adjust the compressor through PLC autocontrol slide valve which can save energy.

3.Directly and clearly display water temperature points and operation times through PLC;

4.Automatically record and store the recent fault alarm and the time and prompt the suggestions on the fault treatment;

5.The original parameters such as inlet and outlet water temperature, the position of slide valve, each protection point of the unit and pressure can be rectified (via password) in accordance with the actual needs.

Original Refrigerating Components and Electric Apparatus

1.Relay, heat protector, expansion valve and pressure controller; the drier-filter adopts the world famous brand product, which greatly increases the reliability of the whole machine.

Easy Installation

1.The unit is so structurally compact that it only covers a little floorage to save the space of the machine room.

2.The unit has been filled with R22 refrigerant and lubricant, which can reduce the installation time and expense.

3.Due to the little vibration of the unit, the base can be provided with no anti-vibration measures.

4.The pipes of the evaporator and the condenser are only required to be connected in time of installation.


1.Refrigeration operation conditions: freezing water inlet temperature 12 C, freezing water outlet temperature 7 C, cooling water inlet temperature 30 Cand cooling water outlet temperature 35 C.

2.This series of the unit is controlled by programmable PLC controller and temperature controller
