Cooling tower
The air-conditioning load goes to an open tower. Evaporation raises hardness. Air and sun grow biofilm.
For your sector
Water Treatment in a Hotel
In a hotel, water carries guest comfort and the steam for the kitchen and the laundry. The tower and the hot water carry a hygiene risk. The closed loop and the boiler are watched separately.
Scale in a cooling tower · Corrosion in a closed loop · Scale in a steam boiler
Where the water is used
Hot water
The guest waits for hot water. A low temperature and a stagnant line hold biofilm.
Chiller and closed loop
Closed heating and cooling water is replaced rarely. Oxygen and sludge attack the metal.
Laundry and kitchen
The steam boiler serves the laundry and the kitchen. Scale raises fuel use.
Risks specific to this sector
Legionella
An open tower and the hot water can grow a Legionella risk if they hold biofilm. C biocide 886 lowers that risk in open cooling.
Guest comfort
If the chiller cannot cool, the room temperature rises. Scale and sludge close the exchanger.
Closed-loop heating
Heating water that is replaced rarely goes to corrosion and sludge. A radiator does not heat in one area.
Kitchen and laundry steam
If steam stops, the kitchen and the laundry stop. Boiler scale burns more fuel for the same load.
What damage does it cause?
Signs
- Algae, foam or a slimy deposit is visible on the tower.
- The room does not cool enough, or a fan coil works only in one area.
- Closed-loop water turns brown, or pump noise rises.
- The laundry needs more steam or more fuel for the same load.
How do you solve it?
Tower biocide
C biocide 886 is put in the program for biofilm in open cooling. Scale needs a separate tower chemical.
Hot-water checks
Check the hot-water temperature and the end point on a regular schedule. Flush a stagnant line.
Closed loop
Put a corrosion inhibitor in the heating circuit. If there is a freeze risk, select the antifreeze separately.
Steam boiler
Treat the laundry and kitchen boiler from the feed water analysis.

Frequently asked questions
How do you lower the Legionella risk in a hotel cooling tower?
C biocide 886 prevents biofilm in open cooling and lowers the Legionella risk. Ck 220 is also used for scale. The application frequency is set from the biological load in the tower.
Where do you look if a guest floor does not cool?
Check the chiller and the closed-loop water. Scale and sludge can close the exchanger. Ck 13 protects the copper surface in the closed loop.
Which product do you select for the laundry boiler?
Cefopol 1040 prevents scale and corrosion in the boiler water. Cemolin 1080 lowers the corrosion risk in the steam line. Both are NSF approved. The choice depends on the feed water analysis.
Why is the hot-water line watched separately?
A stagnant, warm line holds biofilm. Read the temperature and the end point on a regular schedule. This job does not replace the tower biocide.
