Introduction to Water-cooled screw chiller
Water-cooled screw chiller is a high-efficiency cooling equipment designed for industrial and commercial fields. As one of the core equipment of industrial cooling system, it is widely used in plastic processing, chemical, pharmaceutical, food and beverage, injection molding, die casting, rubber molding, composite molding and other industries with its excellent energy efficiency and stable operation performance. Whether it is to provide precise temperature control for production equipment or to create a comfortable indoor environment for commercial places, this chiller can meet diverse needs.
Features of Water-cooled screw chiller
1. High efficiency and energy saving, reducing operating costs
The water-cooled screw chiller adopts advanced screw compression technology and is equipped with a graded energy control system, which can automatically adjust the operating status according to the actual load demand. Its compression ratio can be as high as 20, and its energy efficiency ratio (EER) value is significantly higher than similar products on the market. When operating at partial load, the equipment can still maintain high efficiency and save electricity significantly.
2. Stable and reliable, extending equipment life
The equipment adopts horizontal shell and tube condenser and shell and tube evaporator, which has compact structure, high heat exchange efficiency and easy maintenance. Its unique circular motion design ensures that the equipment has no “surge” phenomenon when operating at low load, with noise as low as 75 dB(A) and minimal vibration. In addition, the equipment uses high-quality materials and precision manufacturing processes to ensure long-term stable operation, with an average trouble-free operation time of more than 20,000 hours.
3. Intelligent control and easy operation
The control system adopts imported PLC program controller, equipped with a 10-inch large-screen touch screen, with a simple and intuitive interface and supports remote monitoring and operation. Users can view the equipment operation status in real time through mobile phones or computers and adjust parameters.
4. Multiple protections, safe and worry-free
The equipment has built-in multiple safety protection systems, including compressor overload protection, water pump overload protection, poor heat dissipation protection, refrigerant shortage protection, freezing prevention protection, high voltage protection, low voltage protection, power reverse phase and phase loss protection, etc. These protection mechanisms effectively prevent the equipment from being damaged under abnormal working conditions and ensure the safe operation of the equipment in various environments.
