Air-cooled Screw Chiller

China Air-cooled Screw Chiller Manufacturer, Yuzhen provides high-performance, easy-to-install, low-maintenance refrigeration solutions and unit configurations that can adapt to cold, hot and complex conditions.

Product core highlights

1. Efficient screw compression system (Hanbell core technology)

Air-cooled Screw Chiller adopts LT-S-H series single unit double-stage screw compressor

High energy efficiency, excellent partial load performance

Stable operation, low noise, long life

Remote monitoring, intelligent adjustment of real-time load, more power saving

2. Shell and tube heat exchanger (industrial pressure design)

Efficient heat exchangers are a key part of Air-cooled Screw Chiller performance

Refrigerant side design pressure: 2.85MPa

Water side design pressure: 1.0MPa

Large heat exchange area and stable structure

Pipeline corrosion resistance, suitable for long-term operation

Suitable for all kinds of industrial cooling conditions (plastics, chemicals, food, pharmaceutical, etc.)

Stable heat transfer performance means faster refrigeration speed and lower energy consumption, which also makes the whole machine more suitable for long-term continuous operation.

3. Advanced microcomputer control system

It is equipped with imported air conditioning equipment dedicated programmable controller PLC, with anti-electromagnetic interference performance, suitable for industrial, factory, power and other complex environments.

Control functions include:

Start-up, operation, shutdown of the whole process management

The outlet temperature can be adjusted to meet the needs of different working conditions.

Automatic fault diagnosis and alarm

Automatic coupling of building load and heating

Chinese interface display, simple and intuitive operation

Intelligent control makes the unit more energy-efficient and stable, and also reduces human error.

4. High efficiency V-fin coil heat exchanger (suitable for low to-35℃ environment)

In order to improve the air side heat transfer efficiency, Yuzhen Air-cooled Screw Chiller adopts high-performance V-type finned coil:

Technical advantages:

V-shaped structure makes the air flow evenly distributed and the air flow smoother.

Large heat exchange area, improve condensation efficiency

Stable operation can be maintained at-35℃ under extremely low temperature environment, and frost is not easy.

High-quality hydrophilic aluminum foil fin, with imported punching machine for secondary flanging and corrugated strengthening treatment

Delays frosting and improves heating stability

5. Efficient axial fan and weatherproof motor fan system advantages:

Efficient axial fan, aerodynamic blade design

After dynamic and static balance calibration, stable operation and low noise

Strong corrosion resistance, suitable for coastal, high humidity environment

Waterproof, rust-proof and weather-resistant structural design

Stable operation at-35℃~45℃

Motor technical characteristics:

Outdoor dedicated motor

F class insulation and process, high temperature resistance

Imported high-quality bearings, no need to refuel maintenance

IP54 protection class, excellent dust and water resistance

Combined with the overall design of fan and motor, the outdoor operation capacity of the whole machine is significantly improved, and the maintenance cost is greatly reduced.

6. Intelligent defrost system

In order to cope with the possible frost problem of the coil under low temperature conditions, the system is equipped with intelligent defrosting function:

Automatic monitoring parameters include:

environment temperature

coil temperature

high and low pressure of refrigerant system

heating operation time

PLC controller will automatically determine the defrost cycle, start and end time according to the real-time situation, and automatically adjust the load to ensure that:

High defrosting efficiency, avoiding frequent defrosting to affect performance

Ensure continuity of heating

Improve winter operation efficiency and save energy
