Cooling Tower Cleaning Services On Line Cooling Tower Cleaning

Industrial counter flow towers can also be cleaned by our trained robots. We can also provide an underwater video inspection of your tower using our ROVs, prior to any  cleaning, or to determine if a cleaning is needed.


If you have a large cross flow tower, our robot technology can provide a video documented cleaning of your basin, regardless of the depth.

​​​​​​Starting on a weekend only basis, OLC Services has grown into a company known as the pioneer in the on-line cooling tower tech field. We also utilize the most advanced underwater inspection equipment to provide the client with a real time view of what is in the tower basin. Underwater inspections have become much safer and easier with no divers or closed entry required. Others are entering the market and imitating the OLC Services technology and that's good for the market. After all, "imitation is the highest form of flattery"!

And, by using OLC, you are also working toward complying with ASHRAE 188 standards and helping reduce the potential of Legionella infection!

Cleaning any size or type cooling tower has always been akin to having a tooth pulled without anesthetic. This problem was solved by a water treatment professional many years ago so the important task of removing debris from the cooling tower could be performed in an efficient and safe manner. As water treatment professionals, OLC Services understands the specialized needs of cooling towers. Add over twenty five years working with underwater robots and you have an experienced team working for you!

​​​​OLC means your system stays in service, no shutdown

​and a cleaner system!
