Purpose
Cleaning and disinfecting cooling towers regularly will reduce lime scale and algae. This will optimise the flow of water/air of the heat exchanger packets and reduce the growth of Legionella.
Execution
To avoid the risk of Legionella in cooling towers, it is important to take water samples at least 1 to 12 times a year (depending on the risk class). The exhaust cones and drip catchers need to be disinfected and chemically cleaned at regular intervals. At an early stage we can draw up a plan of action with you to determine what must be done to minimise Legionella growth.
Disinfection and chemical/precision cleaning
Cooling towers can be cleaned in several ways using high-pressure water or chemicals, depending on the type of contamination.
Typical contaminants are:
- algae;
- lime scale.
Algae will be removed by spraying in the right chemicals and using high-pressure hot water.
It is less simple to remove lime scale. It must be done by circulating the right chemicals to dissolve the lime scale. After performing this work, the cooling tower will be rinsed using high-pressure hot water.
Replacement of drip cathers/heat exchanger packets
PVC drip catchers/heat exchanger packets have a limited service life, depending on the combined effect of the environment, contamination and temperature. We can completely renovate your cooling towers, dismantle and remove the drip catchers/heat exchanger packets, clean them and supply and fit new drip catchers/heat exchanger packets.
