Today there is hardly an industry that doesn’t use powerful cooling systems. They are needed as much in the chemical industry as in the paper and food industries. High-quality cooling water filters reduce the maintenance needed for cooling systems, if they ensure an automatic self-cleaning like the modern backwash filters. Also basket strainers are very durable due to their sturdy design. If special filters for river water  are used as cooling water filters, even mussel larvae have no chance to enter the cooling systems. These advantages are provided by almost all automatic backwash filters from Dango & Dienenthal.

Which components are protected by the filters for cooling water?

In particular, seals respond very sensitively to mechanical stress. The stress is caused by dirt particles that get into the system when filters for cooling water are not used. The cooling water filters are capable of removing even the smallest particles from a size of five micrometres. Dirt particles may settle in the pumps, pipes and nozzles, resulting in a continuous limitation in the efficiency of cooling systems. If high-quality DDS filters are used as filters for cooling water, the performance of cooling systems can be lastingly and fully preserved. In addition, the automatic backwash filters reduce the expenses for the exchange of typical wear parts, which in turn reduces the maintenance cost of cooling systems in the long term. In addition, plant shut-downs caused by defects are avoided by investing in good filters for cooling water. Plant shut-downs mean production downtimes and consequently losses in the possible gains of the company.

Where can cooling water filters be used?

A special type of cooling water filter is the filter for river water. They are urgently needed if the cooling water is obtained from natural water bodies or from wells, since a high proportion of dirt can be naturally expected in the water. Even the dirt in the cooling water in the cooling towers can be removed by these filters. Another field of application is the scale removal in the metallurgical industry and in large rolling mills. Here cooling water filters are necessary both before reusing the cooling water and before returning the old cooling water into water bodies to protect the environment. Another field of application of cooling water filters is in the use of rainwater for the purpose of air conditioning of buildings. Rainwater brings dirt particles from the air and also flushes the dirt accumulated on the roofs into the tanks. Before the rainwater is pumped into the heat exchanger, it should be filtered automatically by high-quality backwash filters of all particles that are detrimental to the air conditioning system.
