After using it for a long time, the heat exchange efficiency has decreased – could it be due to scaling? How to deal with it?
If it has been in use for a long time, the heat exchange efficiency gradually declines, and the likelihood of scaling increases. In such cases, it is necessary to improve water treatment by adding scale inhibitors, as well as performing mechanical and chemical cleaning of the heat exchanger
Yes, scaling has a significant impact on heat exchange efficiency; it is recommended to clean it regularly with a cleaning agent. But it is essential to choose a good cleaning agent; otherwise, deposits such as scale cannot be completely removed, and the equipment may be corroded. The residual acid can cause secondary corrosion or under-scale corrosion of the material, ultimately leading to the need to replace the equipment.
During operation, cold exchange equipment can have its circulating water backwashed regularly, which helps to remove sediment from the tube bundle and thus ensures an excellent heat exchange performance.
Try backwashing first! The heat exchanger used together with it performs fairly well in terms of heat exchange; only that one unit has problems – it can’t handle large volumes of flow! ~
