Industrial Air Cooled Screw Chiller Cooling System for Plastic Industrial Processes

Product Description

Water Cooled Screw Chiller

Water Cooled Screw Chiller is an efficient and reliable industrial chiller unit, with its main components featuring a screw compressor, hence referred to as water-cooled screw chiller. It utilizes a screw compressor and water-cooling heat dissipation method, providing excellent refrigeration capacity and stable performance. The chiller is equipped with a cooling tower or a cooling water circulation system, which utilizes external cooling water for heat dissipation, meeting a wide range of industrial demands. With a wide temperature control range and refrigeration capacity, it can precisely control temperatures between 3°C to 50°C, making it suitable for industries such as plastic processing, chemical, pharmaceutical, and others. Water Cooled Screw Chiller chillers are the ideal choice in the field of industrial cooling, ensuring stable operation of equipment and processes.

 

Application Scope in the Industry

Water Cooled Screw Chillers have extensive applicability in industrial settings. They are used in industries such as plastics (injection molding, extrusion), plastic packaging, automotive manufacturing, electronics manufacturing, electroplating, pharmaceuticals, chemicals, ultrasonic cooling, printing, and others. They maintain stable operating temperatures for equipment and processes, thus improving production efficiency. Water-cooled screw chillers are typically suitable for large-scale cooling requirements in production and processing equipment. They are widely used in industries such as plastic processing (injection molding, extrusion), meeting various process cooling needs, greatly enhancing the production efficiency and product quality of plastic molding machines.

Highlights of the Product

Semi-hermetic Screw Compressor

With low noise and vibration levels, it achieves energy savings of over 20%.

The water-cooled screw compressor utilizes a semi-hermetic screw compressor, offering advantages such as stability, reliability, low noise, and low vibration. During the compression process, gas enters the compression chamber from the suction end of the screw, and as the screw rotates, the gas is gradually compressed and eventually discharged through the exhaust end. The thread shape and rotational motion of the screw ensure the continuity and stability of the gas during the compression process. Zhejiang or Han Zhong, two globally renowned brands, provide the screw compressors used in the Xiecheng water-cooled screw compressor, ensuring long-lasting, efficient, and stable operation. Compared to traditional scroll compressors, it achieves energy savings of over 20%, resulting in more energy-efficient operation

Stepless Capacity from 25% to 100%

Screw compressors feature stepless capacity control, which means that a single compressor can continuously adjust the cooling capacity in any range between 25% to 100%. This allows for precise control of energy output, ensuring stable and efficient operation.

Shell and Tube Evaporator

The Water Cooled Screw Chiller utilizes a shell and tube evaporator. In this system, the refrigerant evaporates inside the heat exchange tubes, while water flows on the shell side. To enhance the heat exchange efficiency, a 2mm thick baffle plate is installed on the shell side, causing the water to flow back and forth to create ice brine. Additionally, to maintain a stable operating temperature, the exterior shell of the evaporator is covered with insulation material.

For the heat exchange tubes, we employ high-efficiency seamless copper tubes. These tubes undergo a grooving process to form internal thread fins, thereby increasing the heat exchange surface area with the refrigerant. With this technology, the heat transfer area is doubled, significantly improving the heat transfer efficiency.

Shell and Tube Condenser

Water Cooled Screw Chiller utilizes a shell and tube condenser, with the internal copper tubes employing an outer thread embossing process. This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.
 

RS485 Remote Communication System

Equipped with RS485 communication capability, this feature enables the integration of the water-cooled screw chiller and plastic molding machine into a single data platform, enabling automated remote management.

Variable Frequency Drive System (optional)

Highly efficient and energy-saving, utilizing world-class onboard variable frequency drive technology, which greatly enhances the partial load energy efficiency of the unit. The highest integrated part load value (IPLV) can reach around 10.
 

Advantages of VFD System

1. High efficiency and energy savings of over 30%.
2. ABB VFD enables seamless and stepless adjustment from 1% to 100%.
3. Soft start feature reduces startup current impact, while the built-in DC reactor minimizes harmonic interference.
