A Few Cooling Tower Facts
1- When water evaporates from the cooling tower, the dissolved minerals are left behind as scale deposits. Excessive scale build-up is a sign of inadequate water treatment.
2- A preventive maintenance program includes regular water treatment and maintenance of the mechanical and electrical systems.
3- Cooling Towers use evaporation to remove heat from an HVAC system.
4- Cooling Tower water must be treated with chemicals(or some alternative), to prevent the growth of bacteria, inhibit the buildup of scale and minimize corrosion.
Preventive Maintenance Schedule For Cooling Towers
Daily cooling tower inspections should include a visual
inspection not limited to checking for noises, vibrations,
and checking chemical station.
Weekly cooling tower inspections should include manually
turning on the tower. Testing water on open loop towers.
Monthly cooling tower inspections should include cleaning
of sump pump screen, check belts, check motor and bearings,
check chemical levels and check towers structure, especially
the motor brackets and mounts. Testing water on closed loop
Bi-annual inspections should include inspection of the
*All deficiencies and problems should be addressed at time of inspection.
It is always good to have a extra set of tower belts.
Quick Overview of Cooling Tower Maintenance Procedures
Cleaning The Cooling Tower
Keeping a clean cooling tower is critical to its operation. Every 6
months the cooling tower should be drained and cleaned using a power washer.
Algae and mineral deposits are a common problems in the New Jersey area.
Visually inspect cooling tower before beginning. Note key areas where
accumulation of debris has built up. Visually inspect nozzles and remove
debris from them. Nozzles are located at the top of the tower. Some times
sticks and leaves get sucked up by the sump pump and the debris get caught
in the header and at the nozzles.
If the cooling tower drain is piped directly to a common drain,
disconnecting drain from piping will prevent clogging (if a union is
installed). Be sure to shut off electrical and water supply before
Power Wash both sides of the drift eliminator. This is
the black PVC wall the water drifts down inside the tower.
Continue power washing the whole tower removing debris and
algae growth. Be sure to sweep everything down the cooling
Whether the pump is located in the building or on the tower, there should
be a screen inside the cooling tower. Be sure to clean this screen to assure
maximum flow of water to sump pump.
Visually inspect heaters for broken or cracked elements.
Heaters usually crack and split. If heaters are dirty, be
sure to remove and clean them.
Replace belts, both high speed and low speed belts if
applicable. Grease shaft bearings and motor bearings if applicable.
Do not over grease, Over greasing can ruin a bearing.
Fill Cooling Tower
Once the cooling tower is filled,
check operation of all
electrical components. Check voltages and amperages of each
component to ensure proper operation. Be sure to reconnect
