What should be paid attention to when cleaning industrial water chiller system?

1. Before cleaning, the power supply must be turned off first. The LC -25°C ~ -5°C Low Temperature Chillers must not splash water onto the motor during cleaning, as this can cause damage to the motor and cause greater losses.

2. For surface cleaning work, use warm water and cleaning agents to ensure that the surface of the industrial chiller is clean and smooth. Grinding cleaning agents and friction pads cannot be used to scrub, as this can cause scratches and damage to the surface.

3. Internal cleaning work must pay attention to protecting the components inside. Water should not be splashed onto the components by the chiller, which can cause damage to the components. Grinding cleaning agents and friction pads should not be used for cleaning, as this can cause scratches and damage to the surface.

Note: Before doing cleaning work, be sure to turn off all power sources to prevent the unit from burning out, otherwise the gains and losses will outweigh the losses.

4. Removing components

Before cleaning the industrial chiller, we first need to remove it because there are many parts inside that are not easy to see and clean, and there are intersections and miscellaneous pipelines. There are also many components that are difficult to disassemble.

5.Connection between cleaning equipment and condenser

Firstly, we first identify the direction of the condenser’s water inlet and connect it to the water pump’s water inlet or outlet, and then heat the pipeline.

The chemical acid cleaning method is suitable for vertical and horizontal shell and tube condensers (steel pipes). The normal operation of the condenser must be stopped during the descaling process to ensure safety.

Principles and methods of chemical acid cleaning for scale removal:

Clean the condenser with a prepared weakly acidic scale remover to remove scale.

Close the inlet valve, outlet valve, balance pipe valve, mixed gas valve, oil drain valve and other valves on the condenser, and stop the operation of the condenser cooling water pump.

Prepare a descaling solution in the pickling tank, start the pickling pump, and circulate the descaling agent solution in the condenser’s condenser tube for 24 hours. Check for scale detachment before determining whether to continue cleaning. Generally, the scale is basically cleared after 24 hours.

After stopping the acid cleaning pump, repeatedly clean the remaining detergent solution in the pipe with clean water until it is completely clean.
