How to clean the condenser of a chiller unit?
Thread Content
The copper heat exchange tubes inside the condenser of the refrigeration units used by the company are currently affected by a large amount of alkaline scale, as the circulating cooling water in use has not been treated. This leads to frequent blockages or poor flow, resulting in alarms on the refrigeration units and very high outlet water temperatures. I would like to ask all the sailors: how do you usually clean your equipment? O(∩_∩)O Thank you
You can buy \"scale remover\" at the market; it’s generally available at places that sell copper pipes and Freon. Then buy a soft brush and a hose, and just brush it. Which brand of refrigerators do you sell? Just call the manufacturer’s after-sales service for guidance – that’s all. Our customers all get guidance by calling the after-sales service; it’s very simple....
Prepare some oxalic acid yourself, making sure the concentration isn’t too high; use a pump to circulate the prepared oxalic acid solution between the two ends of the condenser – this will solve the problem within an hour.
Clean cyclically with a 3% hydrochloric acid solution; once the scale is loosened, scrub it with a pipe nylon brush and water.
Pickling will do; a pigging machine can also be used, but the pressure needs to be controlled so it’s not too high.
Blue Star Cleaning Company specializes in cleaning heat exchangers. We have entrusted all of our previous heat exchangers to them for cleaning, to see the results after cleaning.
It is recommended to contact a professional manufacturer for cleaning, as the heat exchanger consists of copper tubes, which can easily leak if not cleaned properly! I have once cleaned the copper tubes of the heat exchanger in a lithium bromide chiller.
We use citric acid; oxalic acid can also be used, as well as dilute hydrochloric acid. However, it is necessary to neutralize it with an alkali after washing
