Water Cooled Chiller: Definition & Features

What is a water cooled chiller

Water cooled chiller is a refrigeration system that utilizes a continuous water circulation system, transferring heat through a condenser and dissipating it via an external cooling tower. These chillers provide superior cooling efficiency and temperature stability, making them ideal for industries with high cooling demands and access to a stable water supply. They are widely used in metal processing, pharmaceuticals, food production, chemical manufacturing, power plants, and precision machining, ensuring consistent performance and product quality.

AODE water-cooled chillers feature hermetic scroll or screw compressors, offering cooling capacities exceeding 240KW+. With a temperature control range of 5-30°C, they provide high efficiency and low energy consumption. The integration of PLC or microcomputer control ensures precise operation, while high-quality stainless steel plate or shell-and-tube heat exchangers enhance thermal transfer. These chillers operate with lower noise levels than air-cooled models and have a more compact design, as cooling towers are installed separately.

Applications of water cooled chiller
