COOLING SYSTEM Tips

WATER CYCLES-MAKEUP REDUCTION FOR WATER & CHEMICAL SAVINGS

Change once through cooling to 2 cycle changes-50% savings

Change 2 cycles to 3 cycles-additional 16% savings

Change 3 cycles to 4 cycles-additional 9% savings

SYSTEM CONFIGURATION / RECIRCULATING PUMP RUN TIME REDUCTION

A hot well/cold well system can save recirculating pump time.

SEWER CHARGE REDUCTION

Install a water meter on system discharge to sewer as well as makeup to the system. Sewer charge could be reduced. In cities this could mean as much as $3.00 or more for every 1,000 gallons of water.

COOLING TOWER / FAN RUN TIME REDUCTION

Clean deposits between fill.

Clean tower troughs or tower pans which distribute water at top of tower. Make sure that distribution is uniform to the fill below. Make sure that water is not running over the top or side or prematurely off troughs and that water is distributed throughout total length of trough or pan.

PIPING / PUMPS-POSSIBLE FAN OR PUMP RUN TIME REDUCTION

Clean filters on recirculation pumps/Keep system clean.

CHILLER- CHILLER AMP DRAW REDUCTION

Keep chiller tubes clean-Deposits cause significant energy loss.

Tubes should be brushed or acid cleaned if deposit is severe enough.

SYSTEM- REPLACEMENT SAVINGS FROM CORROSION REDUCTION 

Fouled systems impede free water flow and cover areas where corrosion as a result occur. Clean systems prevent "under deposit" corrosion.

The nature of "deposits" may be of corrosion, mineral scale or micro biological growths. Corrosion products appear somewhat like a deposit, but are caused by reaction of the metal with the oxygen in the presence of water and other reactants present in water.
