Cooling tower for waste water application
We have supplied a cooling tower for a chemicals company site in Westerlo-Oevel. The company manufactures products including polymers, with divisions across the whole world.
This cooling tower was to replace an old BAC cooling tower. The customer asked for a low-maintenance and quiet cooling tower suitable for cooling waste water from their water purification installation.
- Because of the composition of the water to be cooled, all parts of the cooling tower had to be made of rustproof materials.
- A number of work openings were provided to give easy access to all components in the cooling tower to be able to carry out inspection and cleaning work quickly and safely.
- Water distribution takes place with special sprayers to avoid blockages.
- The cooling packing is the ABN type which continues to guarantee the required cooling, even with dirty leaves.
- The cooling tower has an extremely quiet fan.
- The cage ladder with platform was manufactured to size on-site to fit the existing platforms.
