There are 4 types of valves that would need to be installed: If using insulation, ensure that there will be no issues with the pipework material you are using. This can be done with a hammer lad or similar material. If installed externally and or within a plant room type area there will possibly be a need to protect it. If it is required, this is usually a fiberglass material covered in an aluminum foil or a type of kooltherm which is a more rigid material. Return Pipework Insulationĭepending on the design and the location the system is installed, pipework insulation may or may not be required. The galvanizing provides protection from accelerated corrosion and pipework degradation when the system is open and, although should be managed via chemical treatment and blowdown/filtration systems, there is always a risk. Carbon steel with the internal painted.Carbon steel pipe work and hot dipped galvanized.The pipework, if an open cooling system, would be manufactured from one of the following materials: There are occasions when a plate heat exchanger would be used and installed between the chiller and tower if the tower is installed at a lower level than the water-cooled chiller, this is described in high-level later in this article. The pipework can be directly connected between the chiller and the tower or, if multiple towers and chillers are used, a common header would generally be utilized. The cooling tower return pipework is installed to transport the warm water from the condenser side of the water-cooled chiller to the cooling tower, with the flow being provided by the condenser water pumps that are installed on the supply side of the tower to move the water around the system.

The pipework that is commonly connected to the towers would be: Depending upon how the towers are installed will mean different configurations would be required. To allow the cooling towers to operate correctly, in line with the design and efficiently, various systems will need to be connected to allow them to work.
