In a chilled water system (recirculating closed loop), water is circulated throughout the building to chilled water coils where the air is passed through and is returned to the room as cooled air. Water Cooled Chillers operate in a closed-loop system which means water is recirculated for a long period of time and only through proper water treatment can we assure that water is a preferred quality.

23/3/2013· ABS pipe chilled fluid circuits are often required to operate at temperatures close to, and well below freezing. To achieve this, a closed circuit containing a mix of glycol and water, along with a secondary heat exchanger is used. The ratio of glycol to water is dependent Puhui Pipe manufacturer in China
* HDPE pipe may face; PE density of 94% of the salt water, because it is up to 96% of the fresh water on the HDPE pipe filled with water even if the water is suitable to swim in. Therefore, be reduced as far as large parts of the ground may be left floating on the water coined.
