Chemical Cleaning Procedure
• Scale deposits are best removed by chemical means.
Consult a qualified water treatment specialist (i.e., one
that knows the local water supply chemical/mineral
content) for a recommended cleaning solution suitable
for the job. (A standard condenser water circuit is
composed solely of copper, cast iron and steel.)
Improper chemical cleaning can damage tube walls.
All of 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.
Note: Chemical tube cleaning should always be followed
by mechanical tube cleaning.
RTUD Air Cooled Condenser Applications -
High Condenser Pressure Limit and High
Pressure Cutout Diagnostics
If a circuit experiences significant time in the High
Condenser Pressure Limit mode, or if it experiences High
Pressure Cutout trip diagnostics, the air cooled condenser
may be the root cause and should be inspected.
The condenser coils should be checked for air flow
restrictions and cleanliness, as well as the possibility of
recirculated air, in which the air entering the coil is
