150HP High-Capacity Refrigeration For Heavy-Duty Industrial Needs Water Cooled Chiller Unit

The chiller is equipped with a high-efficiency twin-screw compressor from international well-known brands, which has obvious advantages compared with traditional reciprocating compressors:

• Energy Saving: The built-in asymmetric rotor design reduces the internal leakage of the compressor, and the volumetric efficiency reaches more than 95%. Under the same cooling capacity, the energy consumption is 15%-20% lower than that of reciprocating compressors, and the annual energy saving for enterprises can reach tens of thousands of yuan.​
• Low Vibration & Noise: The screw rotation speed is stable (3000-4500r/min), and the vibration amplitude is less than 3mm/s. With the matching shock-absorbing base, the operating noise is controlled below 75dB(A), which is far lower than the 85dB(A) of traditional models, creating a quieter workshop environment.​
• Long Service Life: The rotor is made of high-strength alloy steel through precision forging, with a surface hardness of HRC58-62, which is wear-resistant and corrosion-resistant. The design life of the compressor is more than 15 years, and the average maintenance cycle is extended to 2-3 years.Technical Specifications

Cooling System: Water-Cooled Design for Efficient Heat Dissipation

The chiller adopts a shell-and-tube condenser with a large heat exchange area (up to 180㎡). The inner tube is made of copper, stainless steel material available, strong corrosion resistance to industrial circulating water (such as corrosion inhibitors, descaling agents). The water flow channel is optimized by fluid dynamics simulation, which reduces the water resistance by 12% compared with ordinary shell-and-tube condensers, and the heat exchange efficiency is increased by 18%.

It supports matching with various cooling water towers (counterflow, cross-flow), and the water supply temperature can be adjusted between 30-40℃. Even in high-temperature seasons (ambient temperature up to 42℃), it can still maintain stable refrigeration performance through the automatic adjustment of the water flow control valve. At the same time, the system is equipped with a water filter, which can effectively filter impurities in the cooling water, avoid blockage of the condenser tube, and reduce the frequency of manual cleaning by 60%.

Control System: Intelligent PLC for Precise Management
The chiller is equipped with an industrial PLC control system (compatible with Modbus, Profinet protocols), which can realize the following functions:​

Precise Temperature Control: The outlet water temperature can be set in the range of 5-20℃, and the control precision reaches ±1℃. It supports automatic adjustment of the compressor load according to the actual cooling demand (load adjustment range 25%-100%), avoiding energy waste caused by high-load operation under low demand.​

Remote Monitoring & Control: Through the connection with the factory's MES system, managers can view the operating parameters (refrigeration capacity, water temperature, pressure) and fault information of the chiller in real time on the computer or mobile terminal, and remotely control the start, stop and parameter adjustment of the equipment, realizing unmanned on-site management.​

Fault Early Warning & Diagnosis: The system can monitor 32 key parameters (compressor discharge temperature, condenser pressure, water flow rate, etc.) in real time. When an abnormal parameter is detected, it will immediately send a sound and light alarm and a remote message reminder, and display the fault location and maintenance suggestions on the operation panel, reducing the maintenance time by more than 50%.
