Ball Cleaning vs Brush Cleaning: Two Sibling Technologies
HYATCS cleans with a continuous sponge-ball loop. A different online technology — automatic tube brush cleaning — uses a captured brush in every tube, driven by periodic flow reversal.
| Dimension | Ball-type (HYATCS, this page) | Brush-type |
|---|---|---|
| Cleaning media | Free-moving sponge / nano-silicone balls | One captured brush per tube |
| Driving action | Continuous ball loop | Periodic flow reversal |
| Fouling removed | Fresh soft scale | Fresh and hardened scale |
| Debris tolerance | Lower — ball jams possible | High — brush cannot be lost |
| Best fit | Clean-ish water, continuous duty | Dirty / debris-laden water, hard scale |
If your tubes carry hardened legacy scale, or your water carries debris, a brush-type system is usually the better investment. If your water is clean and the unit runs continuously, ball cleaning on this page pays back faster. We will tell you which — honestly.

Frequently Asked Questions
How does HYATCS save energy?
Dynamic tube cleaning prevents fouling and holds the best heat-exchange efficiency, so the system does less work for the same cooling output.
Why don’t I see cleaning action?
Cleaning is intermittent — short cycles, then a long idle, then it repeats. That’s by design to minimize ball wear.
Does it auto-restart after a power loss?
No. For safety it requires a manual restart after power is restored.
How often should balls be replaced?
After ~3000 run-hours or one cooling season, or when worn to the gauge limit.
Why pre-clean an old system first?
Soft balls remove fresh scale but not hardened legacy fouling — pre-cleaning restores a clean baseline for best results.
Why is my approach temperature rising lately?
Balls may be worn, or cleaning frequency is set too low — both are quick to fix.
How do I avoid ball jams?
Keep debris larger than 1.5 mm out of the tubes; add a guard filter if needed.
What are the ball specs and quantity?
3/4″ tube → 16 mm ball; 1″ tube → 22 mm ball. Quantity: 30–50% of one-way tube count.

The Engineering Behind 10–30% Chiller Energy Savings
How continuous sponge-ball tube cleaning actually removes fouling — and why it pays back in months.
An Automatic Condenser Tube Cleaning System (ATCS) keeps every condenser tube interior clean without shutting the chiller down. At its core is a recirculating loop of elastomer sponge balls, each sized about 1 mm larger than the tube inner diameter. On a timed cycle — typically every 1–2 hours, or continuously on demanding duty — balls are injected from the collector into the condenser inlet water box, carried by the cooling-water flow through the tubes where they wipe the wall free of biofilm, scale and silt, then trapped at the outlet strainer and returned to the reservoir. Recovery exceeds 99%, so one ball set keeps working for 6–12 months.
Condenser fouling is the largest controllable efficiency loss in most chiller plants. As little as 0.1 mm of scale or biofilm raises condenser pressure and shrinks the log-mean temperature difference, forcing the compressor to work harder. Field data shows a 1 °C rise in condensing temperature increases compressor power by roughly 2–3%, and a moderately fouled condenser can lose 5–15% of its capacity before anyone notices. Left unmanaged, fouling also drives a higher approach temperature, more frequent compressor cycling, and faster tube corrosion.
Because ATCS removes fouling the moment it forms, the condenser runs near design cleanliness continuously. Across our installed base this delivers a 10–30% reduction in chiller-plant energy use versus a manually cleaned baseline, with the widest gains on plants that previously cleaned only once or twice a year. For a 1,000 RT plant running 6,000 hours per year at about 0.6 kW/RT, a 15% saving equals roughly 540,000 kWh a year — close to 320 tonnes of CO₂ at grid average, and a utility bill cut in the five-figure USD range.
The balls are not generic — diameter, density and sponge porosity are matched to the tube material (copper-nickel, titanium or stainless) and to the water chemistry. Being slightly oversized, each ball self-centres and deforms just enough to sweep the full circumference without scoring the tube, so months of continuous cleaning leave the wall finish unchanged. For brackish or seawater loops we specify anti-microbial, UV-stable compounds so the balls do not degrade between cycles.
A PLC drives the cycle from differential-pressure or timer logic, so cleaning intensity follows the actual fouling rate: a light-load winter may need one pass a day, while a biofilm-prone summer peak can run continuously. Cycle counts, ball loss and strainer status are logged and pushed to the plant BMS, giving the facilities team a fouling trend they can act on instead of a surprise overhaul.
Representative result — district-cooling plant, Southeast Asia: two 800 RT centrifugal chillers on a seawater-assisted tower, cleaned manually each spring. Before ATCS the condensers averaged a 2.1 °C approach rise over the season; after retrofit the approach held within 0.3 °C of design. Measured chiller kW/RT fell from 0.62 to 0.53, a 14% drop, and a 12-month tube inspection showed no measurable scale. The plant had been dosing anti-scalant and biocide through the season; after ATCS the dose could be trimmed, adding a secondary saving on treatment chemicals. Simple payback on the retrofit was 11 months.
Against manual brush or chemical cleaning, ATCS needs no plant shutdown, adds no corrosive chemicals to the loop, and removes the labor and confined-space risk of entering the water box. Unlike full-flow filtration, which only slows particulate buildup, ball cleaning physically scrubs the tube wall, so it also controls biofouling and soft scale that filters miss. It complements blowdown and side-stream filtration rather than replacing them. ATCS ships as a skid-mounted, factory-tested package that ties into the existing condenser water boxes with minimal piping and reports ball inventory and cycle counts to the plant BMS — the foundation of a chemicals-free fouling strategy where water treatment is not yet in place.
Sizing an ATCS is straightforward once the condenser is known. Ball quantity tracks tube count and bore — typically one ball per 8–12 tubes plus spares — and the collector and catcher are matched to water-box geometry so every tube sees flow. Strainer mesh is chosen fine enough to catch the balls yet coarse enough to pass debris, and the whole loop is pressure-rated to the condenser design so it adds no parasitic load on the cooling-water pump.
Operation is largely hands-off. A monthly glance at the BMS confirms ball inventory and cycle counts; the strainer is hosed down during the normal condenser inspection window, and a full ball change takes under an hour. Because cleaning is continuous, the seasonal “shock” descale and the overtime labor that came with manual methods drop off the maintenance calendar.
Unmanaged fouling usually surfaces as:
- Rising condenser approach temperature and compressor amps
- Longer run hours to deliver the same cooling load
- Earlier compressor overhaul and tube-bundle replacement
- Higher biocide dose needed to hold biological growth

Frequently Asked Questions
What does ATCS stand for in HVAC?
ATCS stands for Automatic Tube Cleaning System — also called an automatic condenser tube cleaning system. It continuously cleans chiller and condenser tubes online, without shutting the plant down, using recirculating sponge balls.
How does an automatic condenser tube cleaning system work?
Sponge-rubber balls slightly larger than the tube inner diameter are injected into the condenser water flow. They traverse each tube, scrub the inner wall, are trapped by a strainer at the outlet, and recirculate on a timed cycle — keeping every tube fouling-free 24/7.
What causes condenser tube fouling?
Biofouling (micro-organisms), mineral scaling from hard water, corrosion products, and suspended solids accumulate on tube walls. This raises the condenser approach temperature and forces compressors to consume more energy.
How much energy can an ATCS save?
Typically 10–30% on chiller-plant energy, depending on cooling-water quality and fouling rate. Most sites recover the investment in under two years through lower kWh and deferred tube replacement.
ATCS vs manual or chemical cleaning?
Manual brushing and chemical cleaning require shutdowns, labour, and often harsh biocides. An ATCS runs continuously, online, and largely chemical-free, protecting tubes from permanent scaling rather than removing it after the fact.
