Eurotec Water Chiller System

Introduction of Eurotec’s Water Chiller System

Eurotec’s Water Chiller System specializes in chilling the water for concrete mixers from 46°C down to 0.5°C through an evaporative condenser with a four-stage water chilling system. The heat exchanger plate at the third stage is able to produce 0.5°C of chilled water to supply for use in the concrete mixing process. The parallel arrangement of the compressor allows it to be able to save more than 25% of energy compared to other water chillers. The water circulation system can recycle the water continuously, hence saving it. The modular concept of the water chiller system makes it easier for it to be delivered to the job site.
 

Water Chilling Procedure

First Stage

This stage uses an evaporative condenser to achieve the convincing effect of reducing the temperature of the water from 46°C to 36°C with minimal power required.

Second Stage

The water enters the first compartment of the compressor and cools down the temperature inside the heat exchanger from 36°C to 12°C. The heat exchanger is made out of stainless steel plates.

Third Stage

Subsequently, the high quality of the heat exchanger cools down the temperature of the water further from 12°C to 4°C.

Fourth Stage

Finally, the water is cooled down from 4°C to 0.5°C inside a heat exchanger that is custom made. There are stainless steel plate heat exchangers with water and an air distribution system to ensure a constant temperature of the water inside the tank.
