Chemical Cleaning Procedure
Scale deposits are best removed by chemical means. Consult qualified water treatment specialist
for a recommended cleaning solution. A standard chilled water circuit is composed solely of
copper, cast iron and steel. Improper chemical cleaning can damage tube walls. All the materials
used in the external circulation system, the quantity of the solution, the duration of the cleaning
period, and any required safety precautions should be approved by the company furnishing the
materials or performing the cleaning. Figure 22 shown the typical backflushing unit of the
evaporator.
Note: Chemical tube cleaning should always be followed by mechanical tube cleaning.
