Closed Loop Cooling Water System

The engine is cooled by a special coolant fluid which transfers the heat from the engine to the heat exchanger which is then cooled by the external water.

For cost efficient and long lasting closed loop cooling count on alfa laval s broad range of plate heat. This loop does not require continuous city. In a closed system water circulates in a closed cycle and is subjected to alternate cooling and heating without air contact. To cool key processes in petrochemical plants refineries power plants and other heavy duty industrial environments many plant owners and operators rely on closed loop cooling as the preferred cooling method.

Cooling or heating systems that use water can have one of two main types of systems for dissipating heat acquired by the liquid closed loop or open loop. Each has its advantage when part of a cooling or heating system. 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. The critical difference between these is the amount of exposure the water has to the air.

Depending on your current operation installed pay back on a closed industrial cooling system can be achieved in months. 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. A closed loop cooling system is a more complex system which is very similar to a car s cooling system. As the water flows through the tower it is open to the atmosphere.

Because of evaporation at the cooling tower city water is introduced to replace the evaporated water. Thermal precision closed loop cooling systems are designed to substantially decrease or even eliminate the hidden costs of operating your water cooled equipment. A closed loop system would be from the chiller to the air handling units. With very real concerns about the higher water consumption of open loop systems closed loop cooling technology is gaining broader appeal every year.
