Water-cooled screw chiller system composition:

The water-cooled screw chiller unit is mainly composed of a semi-hermetic screw compressor, shell-and-tube condenser, drying filter, thermal expansion valve, shell-and-tube evaporator, and electrical control section.

Water-cooled screw chillers are also a type of chiller. Due to the use of screw compressors as their main components, they are referred to as water-cooled screw chillers. Their chilled water outlet temperature ranges from 5℃ to 20℃, and they are widely used in various industrial processes requiring chilled water, such as plastics, electroplating, electronics, chemical processing, printing, food processing, and others. They are also suitable for large-scale commercial buildings, hotels, factories, and other central air conditioning systems where centralized chilled water supply is needed.

Product Features: Water-cooled Screw Chiller Unit

(1) The unit is equipped with a branded semi-hermetic screw compressor and electrical control components, along with a condenser and evaporator made of high-efficiency copper tubes for heat exchange.

For example:

Plastic Industry: Accurately control the mold temperatures for various plastic processing, shorten the injection molding cycle, and ensure the stability of product quality.

Electronics Industry: Stabilizes the molecular structure of electronic components during the production line, enhancing the pass rate of electronic components. Applied in the ultrasonic cleaning industry, it effectively prevents the evaporation of expensive cleaning agents and the associated harm to individuals.

Electroplating Industry: Control electroplating temperature, enhance the density and smoothness of plated parts, shorten the electroplating cycle, improve production efficiency, and enhance product quality.

Mechanical Industry: Control the hydraulic system's oil pressure temperature, stabilize oil temperature and pressure, prolong the service life of the oil, and enhance the efficiency of mechanical lubrication, reducing wear.

Construction Industry: Supplies chilled water for concrete, ensuring the molecular structure of the concrete meets the requirements for building use, effectively enhancing the hardness and toughness of the concrete.

Vacuum Coating: Control the temperature of the vacuum coating machine to ensure high-quality coating.

Food Industry: Used for high-speed cooling after food processing to meet packaging requirements. Also includes controlling the temperature of fermented foods.

Textile Industry: Cryogenic drying of air to ensure product quality.

Mold cooling systems are widely used in various fields, primarily in applications such as:

Chiller units can be used with vacuum equipment. These chillers also meet the requirements of high-quality vacuum equipment, such as molecular pumps, small vacuum evaporators, etc.

Please note the following during the operation of the cold water machine:

First, add a liquid medium to the slot before use. Next, the working power supply should be determined according to the machine model, with the power rating being greater than or equal to the total power of the instrument. The power supply must have a good grounding. Furthermore, the chiller should be placed in a dry, well-ventilated area, with at least 400mm distance from obstacles on the side where the chiller is located. After using the chiller, turn off all switches to the off position, disconnect the power plug, and use a vacuum pump and a rubber hose to remove all liquid from the slot.

The chiller can be used with matching experimental condensation equipment, such as a rotary evaporator, a distiller, and a condenser tube. It features adjustable temperature, stable temperature, and high condensation efficiency, which can effectively improve the recovery rate. Additionally, its fluid purification function can prevent pipeline blockages and the growth of microorganisms.

Chiller units are used in conjunction with semiconductor laser equipment. Semiconductor laser equipment, due to its unique structure, has high requirements for water quality.
