After this chiller had been overhauled, we switched Chiller 3 off which brought Chiller 1 on. The next chiller in standby was Chiller 2. We decided to start work on Chiller 1 as this was a system in standby. Therefore, only two of the 4 chillers run at any one time.Ī sequencer is available to switch between the chillers when they go into fault and to balance the compressor run hours. In this instance, the factory would grind to a halt if the chillers went down. Redundancy is needed when a process is critical. Where N is an amount of something and +1 means another one. This is an algebraic way of saying that there is twice as much cooling as is needed. This process is how the contaminants from the air end up in the water. The air flow cools down the water, which then returns to the condenser. In the opposite direction, air is blown up using large blowers. It runs down along plastic slats which are stacked on top of each other. The condenser cooling water enters the cooling tower at the top. Each condenser has a water tower which is open to atmosphere. We think that the fouling was due to contaminants that were carried in the air from around the factory. This showed us that an overhaul needed to be carried out on the condensers. When we looked through our Tick Sheets we could see a gradual deterioration of the high side readings over a period of time. The chillers cool down a process involved with the production of an industrial chemical. The factory has 4x water cooled centrifugal chillers with a combined cooling capacity of 8 MW. ![]() Centrifugal Chiller Condenser Tube Cleaning We have The Spanish Office near Malaga with a manager and an engineer out in the field- so our Spanish engineer assisted our overseas engineer. A nice job for our overseas engineer: to carry out chiller condenser tube cleaning in Cadiz, Spain.
