Air-Cooled Chillers

Air-Cooled Chillers

Air-Cooled Chillers often suffer from atmospheric pollution on the coils. This (greatly) reduces the air flow and therefore the heat transfer will drop as well. Regular cleaning of these systems is therefore extremely important.

Air-cooled Chillers Cleaning and Maintenance

Air-cooled chillers have coils which need to be cleaned regularly. When these coils are full of atmospheric pollution, the airflow will drop greatly. However, it is (very) important that there is a free air flow. If this is not the case (e.g. due to deposits on the fins), the system will offer reduced heat transfer. This is because the condensing temperature rises greatly. This will increase energy consumption quickly and significantly. In some cases, a fouled chiller can use 10 to 30% more energy than a cleaned system with maximum airflow!

High pressure cleaning systems are often used to clean, while this is not the right choice. When working with high pressure, the chance of flattening the coils is much higher. In addition, the low water flow is not enough to ensure optimal rinsing of the system.

Advantages Low-pressure Cleaning / Maintenance (Goodway)

Goodway's cleaning systems offer a low pressure (+-30 BAR) with a flow of 12 litres/minute. This makes it very unlikely that any fins will be flattened. Furthermore, there is enough water available to flush the coils properly. When rinsing/flushing is sufficient/abundant, the contamination will literally be pushed through the coils. Making them clean and open again, so that maximum air flow is possible again. Which ultimately always leads to a better efficiency and lower energy / operating costs!

Cleaning of the Evaporator

In addition to the coils, it is also important to clean the evaporator tubes once in a while. There may be internal fouling/contamination in the tubes, which causes a negative effect on the evaporation effect (heat-transfer). Due to that, the efficiency of the system will drop sharply. By introducing a preventative cleaning, you can ensure that the system will remain operating at peak performance.

Mechanical cleaning of the tube bundle will remove deposits quickly and effectively, at low pressure. This is a huge advantage, since the tubes are not at risk to be internally damaged. On this page, you can read more about the mechanical/brushing equipment.

Cleaning without disassembling fans

One of the other advantages of Goodway equipment is that Air-cooled chillers can be cleaned from inside to outside as well as outside to inside. This can be done by using the 90 degree lances. These can be pushed through the fans. Without disassembling them. This not only saves an enormous amount of time and labor, but also in safety for the cleaning operators.
