Compressor casing heater
Check:
 closure

Operation
Water side heat exchanger
The exchanger must to be able to provide the maximum thermal
exchange, therefore it is essential for the inner surfaces to be
clean of dirt and build-up.
Periodically check the difference between the temperature of the
supply water and the condensation temperature: if the difference
is greater than 8°C–10°C it is advisable to clean the exchanger.
The clearing must be effected:
 with circulation opposite to the usual one

with a speed at least 1,5 times higher than the nominal one

with an appropriate product moderately acid (95% water +
5% phosphoric acid)

after the cleaning rinse with water to inhibit the action of any
residual product
Water filter
Check that no impurities prevent the correct passage of water.
Flow switch

controls the operations
 remove incrustations from the palette
Circulation pumps
Check:

no leaks
 Bearing status (anomalies are highlighted by abnormal noise
and vibration)
 The closing of terminal covers and the correct positioning of
the cable glands.
Electric fans
Check:
 the fans and the relative protection gridsare well fixed

the fan bearings (evident by noise and anomalous vibrations)

the terminal protection covers are closed and the cable
holders are properly positioned.
Insulations
Check the condition of the insulations: if necessary, apply glue
and renew the seals.
Structure
Wash with warm water.

Do not use chemicals.
Check the state of the structure and the presence of oxidation.
Paint if necessary.
