Cooling Tower Cleaning While In Service
Cleaning a cooling tower rates right up there with a tooth being pulled in most engineers’ minds — and for good reason. The old way means shutting the system down, draining the basin, shoveling out the muck, refilling it, and re‑dosing chemicals you already paid for once.
There’s a better way.
OLC cleans your cooling tower while it stays running. No shutdown. No drained basin. No starting your chemical program over from scratch.
Whether your tower is wood, galvanized, fiberglass, or concrete — large or small — we’re the best at what we do.

About Us
Services
Most building owners and facility managers don’t think about their cooling tower until something breaks. But a tower that isn’t regularly cleaned is quietly costing you in four ways at once:
Sludge and biofilm in the basin are exactly where bacteria like Legionella take hold. This isn’t just a maintenance issue, it’s a liability issue. Regular mechanical cleaning is one of the most effective things a facility can do to keep that risk down.
Left alone, scale and debris “bridge” the tower fill, sealing off airflow and choking the tower’s ability to cool.
A fouled tower can’t reject heat efficiently, so the chiller and compressor work harder to hit the same target. That inefficiency shows up on the electric bill every month.
Corrosion, scale, and debris wear down basins, fill, and structural components faster than they should.
Regular on-line cleaning addresses all four at once — without ever shutting your system down.
Evaluate the amount and type of debris in the basin and assess the tower’s condition.
Remove sludge and buildup using a centrifugal filtration system and pressure washing, all while the tower remains fully in service.
Filtered water goes back into the tower, so you’re not losing chemical, water, or the sewer credit tied to it.
You get a clear record of what was found, what was done, and what was removed.
We help you put a regular maintenance schedule in place, built around your system’s specific needs, to extend equipment life, keep electricity costs down, protect your chemical and water investment, and reduce liability exposure for building personnel.
Select OLC packages also include regular Legionella testing as part of an ongoing maintenance plan — giving you both the mechanical cleaning and the documented water‑quality monitoring in one program.
A trained OLC professional will survey your needs and provide a complete analysis for your specific system, along with a maintenance schedule built around how your tower is actually used.

Hospitals and medical campuses run cooling towers around the clock with zero tolerance for downtime or Legionella risk. On‑line cleaning keeps your system compliant and running without ever interrupting critical operations.
Office towers depend on their cooling systems to keep tenants comfortable every day. We clean on a schedule that never takes your building offline or disrupts tenants.
Retail centers, hotels, and mixed‑use properties all rely on cooling towers that simply can’t go down during business hours. OLC keeps your system clean without ever shutting off the cooling.
Apartment and condo towers can’t ask residents to go without air conditioning. On‑line cleaning means comfort never gets interrupted for maintenance.

FAQ
No. That’s the core of what we do — OLC cleans while your tower stays fully operational. No downtime, no production loss.
No. We filter and return the water to your system instead of draining it, so the chemical you’ve already dosed stays in the loop.
Yes. Removing sludge and biofilm from the basin is one of the most effective things a facility can do to reduce the conditions Legionella needs to grow. Select packages also include regular Legionella testing as part of your ongoing maintenance plan.
It depends on your system — usage, water quality, and tower design all factor in. We evaluate your specific tower and recommend a maintenance schedule that fits it, rather than a one‑size‑fits‑all interval.
Anything from a small single‑cell rooftop unit to large multi‑cell industrial and petrochemical installations.
A clear record of what was found, what was cleaned, and what was removed — documentation you can keep on file.
Yes. OLC carries full general liability and Workers’ Compensation coverage.
We’re based in Houston and serve properties across Texas.
Nothing. A trained OLC professional will assess your tower and provide a complete analysis at no cost.

Every month your tower goes uncleaned is another month of lost efficiency, wasted chemical, and buildup that’s harder to remove the longer it sits. A no‑cost evaluation costs you nothing and tells you exactly where you stand.
