Brand Full Closed Screw Compressor Air Cooled Screw Chiller

The main unit is equipped with semi-hermetic screw compressor, integrating the motor, without worrying about shaft seal leakage. 
The single or more compressors are provided with startup-shutdown cycle control program so as to uniformly load parts and extend service life. Multiple refrigerating circuits are provided for the unit, and when one circuit is under maintenance, other circuits are able to run normally as mutual standby. Unload and step down voltage start is provided for the compressors to prevent the impact on the power grid.
Ultra-low noise turbine blade design.
V-shaped appearance provides better heat dissipation.

 

The high-temperature unit is able to provide 55-60ºC hot water for air conditioning system, and the heat recovery type provides water for living, which conform to the Head-Power's high requirements on energy saving.

 

The unit enjoys compact structure, covers small area, saves machine room space; it almost not vibrates due to the provision of foundation anti-vibrating measure.
Upon delivery of the unit, the refrigerant and lubricating oil have been filled into it, then it's only necessary to connect the evaporator water pipe during installation, saving time and cost.

 

Intelligent program control can be achieved for the unit according to the load demand: 100%, 75%, 50%, 25% (or start), 0 and stepless energy adjustment, reducing energy consumption. 
Total parts number of screw compressor is only 1/10 that of the reciprocating compressor, enabling the unit to have simple structure and less venerable parts, without the use of air intake and exhaust valves, not sensible to wet stroke and extremely low fault rate.
Failure-free operation time of the screw compressor is up to 40,000 hours.

 

Pressure protection: High and low-pressure protecting devices
Motor protection: Voltage-loss protection, phase-loss protection, inverse phase protection and over-heat protection. Anti-freezing protection: The unit will stop running in case of excessively low chilled water temperature
.
Above device protections ensure the safe and reliable running of the unit.

For example.

Refrigerant Analyzer

We have two items of Refrigerant Analyzer. One is R1234yf Refrigerant Analyzer and the other one is MINI R1234yf Refrigerant Analyzer.

The introduction of R1234yf Refrigerant Analyzer is as follows:

We adopt NDIR technology on MINI R1234yf Refrigerant Analyzer. This Refrigerant Analyzer can accurately identify the composition and purity of R1234yf Refrigerant, the accuracy of which is not less than 96%.

1. The detection procedure is easy;
2. Finish by one step;
3. Large LCD screen display, showing the detecting result and mistake prompt
4. Small body, tiny weight, portable carry;
5. Suitable for hand-held operation;

C/A-1234yf Refrigerant Analyzer introduction:

C/A-1234yf is a professional R1234yf refrigerant analyzer researched and produced for new A/C refrigerant.

C/A-1234yf refrigerant analyzer can detect the composition and purity of R1234yf Refrigerant. The Refrigerant Identifier R1234Yf
will automatically alarm if the R1234yf Refrigerants are unqualified. It also can detect R134a refrigerant and show various composition content ratio from R1234yf, R134a, R12, R22, to HC.

1. Large LCD screen display;
2. Fast detect with only 60 seconds
3. Accuracy: ±0.1%;
4. Built in printer
5. Print detecting result in real time;
6. Easy to operate;
