Closed Circuit Cooling Water System

As shown in the diagram below raw water is picked up through the drive pickup or through a hull mounted pickup if present it will pass through a sea strainer to clean debris out of the water.

Closed circuit cooling water system.

Failure of a closed system has the potential to shut down a portion if not all of the plant. Heat absorbed by the water in the closed system is normally transferred by a water to water exchanger to the recirculating water of an open recirculating system from which the heat is lost to atmosphere figure 32 1. Our closed loop water treatment solutions address the problems of corrosion fouling biofouling and scaling that. Over the past decade evapco has pioneered innovation in the closed circuit cooler market along with advancements and refining of tried and true open loop equipment options.

The full closed cooling system is designed to circulate cooling water through the block and exhaust maniolds. Due to the higher maintenance requirements of an open system this type may have a higher price over time compared to a lower maintenance closed circuit system. P rimary cooling at steam generating power plants and many other heavy industries is a critical aspect of operation and upsets can cost a great deal in lost efficiency and production. There are two different types of cooling towers.

Closed circuit cooling towers and open circuit cooling towers. With very real concerns about the higher water consumption of open loop systems closed loop cooling technology is gaining broader appeal every year. The process involves cooling the water inside the tubes in addition to a refrigerant. Water treatment services is a leading independent uk water treatment company offering a full range of expert services for the management of closed systems closed loop heating cooling and closed circuit chilled water systems.

The addition of fill to the traditional closed circuit cooling tower design reduces evaporation in the coil section reducing the potential for scaling and fouling. Cooling towers extract waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Both types of towers serve the same purpose but they go about cooling the water in different ways. Bac s combined flow closed circuit cooling towers utilize parallel flow of air and spray water over the coil and crossflow air water flow through the fill.

Certain processes require a closed loop whereby the process water for cooling does not come in contact with the atmospheric air. This prevents the cooling water from picking up particles that may not get filtered or even dissolved gases. Closed circuit cooling systems. A closed loop cooling system can exchange heat with the main cooling water system in conventional tube and shell heat exchangers or plate and frame heat exchangers.
