CLEANING

EVAPORATORS

Minerals and other water system contaminants produce deposits, scales, slime, or algae on the heat-transfer surfaces exposed to water. Fouled surfaces decrease cooling capacity. We recommend that you consult a water treatment specialist to develop a treatment program that will minimize fouling.

To clean the evaporator:

1

Consult a water treat-

 

 

ment specialist for rec-

 

 

 

 

ommendations on the best

 

 

chemicals to use to remove

 

 

contaminants from the

 

 

evaporator and process fluid

 

 

circuit surfaces that come in

 

 

contact with water.

 

 

Thoroughly flush

CLEANING

CONDENSERS

For water-cooled condensers:

You should consult a water treatment specialist for recommendations on the best chemicals to use to remove contami- nants from the condenser. Thoroughly flush chemicals from the condenser before resuming operation.

For air-cooled condensers:

The air-cooled condensers can accumulate dirt and clog quick- ly if it is run in a dusty or dirty environment. A clogged condenser increases refrigerant pressure, lowers performance and may cause the fan motors and compressor to overheat.

1 Clean dirty coil surfaces with a soft brush.

Brush and rinse in the direction of the fins to prevent bending the fins.

2 Rinse with cool water or

acommercial coil cleaner.
