How to clean fouling on heat exchangers
Thread Content
Our company’s circulating water is quite dirty, and the condensers in the workshops are severely scaled up, which prevents them from performing their heat exchange function properly. The image shows the scaling on the jacket of the vacuum pump; the situation is even worse in the heat exchanger. We tried cleaning it by soaking it in citric acid and running a circulation process for 8 hours, but the effect was not very significant. It can be washed away with a high-pressure water gun, but only the flange area can be cleaned; the interior cannot be reached. I’m asking for advice: which type of acid is generally better for cleaning heat exchangers? Aminosulfonic acid? The circulating water flows through the shell side. Chemical Equipment and Machinery
It’s similar to our situation. The problem lies in the shell side through which the circulating water flows.
Scaling is more severe and a common phenomenon; indeed, there isn’t really any better way to remove it.
For direct circulation water treatment, you can consider our technology – magnetization treatment – which can completely solve your problems with scale formation, prevent the growth of new scale, and remove existing scale as well.
Proceed with pickling directly; after adjusting the concentration, circulate it

Pickling can be used, followed by neutralization after washing
When cleaning heat exchangers, there are two types of cleaning nozzles: soft and hard. Consider the soft one
Your situation can be resolved easily. It is sufficient to use both a water treatment device and an electrochemical descaling system. There’s no need to clean it.
