Tips for Removing Fouling of Water Cooled Industrial Chiller

During the process of production in factory, many chillers wok under the temperature of subzero 45 to zero, and their inner tube wall of condenser is easily fouled, which will affect the heat transfer effect and increase the condensing temperature of  the chillers, and then reduce the cooling capacity and increase the power consumption. So how can we clean it?

1. Close valve of the condenser for the entry of cooling water, use the thermometer tube, the pressure gauge tube or the drain pipe to connect the anticorrosion pump and the dispensing tank to make a small circulation system and clean it in recycle.

2. Add the pickling inhibitor first, which is a special copper corrosion inhibitor. It adheres to the inner wall of the condenser and prevents acid reacted with metal.

3. Add solid acid washing agent, which is used to clean the fouling with the main component of calcium carbonate. The agent is a compound solid organic acid, white crystal, no corrosion to metal, weak acid, and the dosage is determined by the fouling degree of equipment.

4. Add dirt stripping agent (optional), if the condenser equipment is thicker, add dirt stripping agent to promote the products of fouling reaction to quickly dissolve in water and accelerate reaction.

5. Add neutralization passivator, after chemical cleaning of the condenser, neutralizing residual acid to prevent oxidation of metal surface and generate floating rust.
