(1) Sterilization and algae elimination: by adding bactericidal agents, all kinds of bacteria and algae in circulating water are removed.

(2) Biological stripping agent, which peels off the biological slime in the pipeline, and cleans the slime out through circulation.

(3) Chemical cleaning: add comprehensive chemical cleaning agent. Air-conditioning maintenance manufacturers stated that this cleaning agent has the effects of corrosion inhibition, dispersion, and descaling, and it treats the water circulation system. This treatment method can not only remove the rust, dirt, and oil stains in the pipeline after cleaning, but also prevent the cleaning agent from harming the system devices and pipelines, and provide a clean metal surface.

(4) Surface pre-filming: Put in pre-filming agents to form a dense polymer polymer protective film on the metal surface to protect it from corrosion.

(5) Shanghai decoration design manufacturer introduces the role of daily maintenance: adding a comprehensive daily maintenance treatment agent has the effect of inhibiting corrosion and avoiding metal rust. The daily maintenance treatment agent contains a polymer complexing scale inhibitor, which prevents calcium and magnesium ion crystal precipitation through complexation, prolongs the service life of the unit, saves water and electricity, and can improve the cooling efficiency. In addition, regular spot checks are required to monitor the water quality.
