SOLUTIONS · COOLING TOWERS
AvailableKnow the chemistry at the tower before the customer sees a deposit.
AquaAdvisor models cycles of concentration, mineral saturation and CCPP, inhibitor demand, deposit risk at hot surfaces, corrosion regimes, and biological risk conditions — from the controller and lab data you already collect on the account.
WHAT GOES WRONG
What goes wrong in cooling towers
Most failures your program is hired to prevent are chemistry and holding-time problems that trending never names until the exchanger or basin already paid for them.
Cycles run past mineral limits
Makeup quality drifts and blowdown lags. Calcite, gypsum, or silica saturation climbs at the hottest wall long before bulk conductivity looks alarming — and the account feels it as fouling, not as a chart.
Inhibitor depletes without a trajectory
Demand rises with cycles, temperature, and surface area. A weekly residual reading does not tell the account team when the next dose window closes.
Corrosion regimes flip quietly
Mild steel, copper alloys, and galvanized surfaces respond differently as pH, oxidant, and chloride shift. Screening indexes miss mixed-metal couples the program is supposed to protect.
Biological risk hides in holding time
Warm, low-turnover basins and long holding times create Legionella-relevant conditions that a conductivity chart never flags — the gap the program you deliver is hired to close.
WHAT AQUAADVISOR MODELS
What AquaAdvisor models
Mechanistic chemistry and asset physics — not a renamed dashboard of controller points.
- Cycles of concentration, makeup/blowdown balance
- Calcite, gypsum, and silica saturation and CCPP
- Inhibitor demand and depletion
- Deposit risk at hot surfaces
- Corrosion of mild steel, copper alloys, and galvanized
- Holding time index; biological and Legionella risk conditions
- Drift and evaporation water accounting
DATA BY FIDELITY
Required data inputs by tier
Start with what you already collect on the account. The same tower model sharpens as telemetry and lab cadence improve.
Baseline
- Makeup and blowdown rates or volumes
- Controller conductivity / cycles estimate
- Periodic lab chemistry (cations, anions, silica, alkalinity, pH)
- Basin or return temperature
Instrumented
- Field ORP / free oxidant, pH, and corrosion coupons or probes
- Inhibitor residual and product feed rates
- Daily or shift lab cadence on critical ions
Hourly speciation
- Hourly sensor coverage on loops feeding the twin
- Exchanger duty or approach temperatures where available
- Inventory and delivery reconciliation for products
High fidelity
- Geometry and materials for reduced-order thermal correction
- High-frequency correction streams for closed-loop readiness
OUTPUTS
Outputs and decisions enabled
Every chemistry result carries residual, database, activity model, and solver tier.
- Defensible cycle limits by mineral, not rule of thumb
- Saturation / CCPP at bulk and hot-surface conditions
- Inhibitor demand trajectory and depletion risk
- Corrosion rate screens (mpy) by material class
- Holding time index and biological risk context
- Evaporation, drift, and makeup water accounting
Decisions enabled
What you can decide
- Whether to raise or cut cycles this week on the account
- When to adjust feed before a deposit event the customer would feel
- Which sensor to recommend next on the account (value of information)
- Whether the Legionella program you deliver matches modeled risk conditions
COMPLIANCE OVERLAYS
Relevant compliance overlays
- ASHRAE 188 water management program structure for the evaporative programs you deliver
- Monitoring plans you write that can consume modeled risk context (holding time, oxidant demand, warm low-flow conditions)
- Append-only audit trail when the Legionella program layer is enabled
- Jurisdiction packs listed explicitly where shipping — coverage is not implied as complete
AI IN THIS ASSET
AI on cooling tower chemistry
Insights and setpoints for the cooling-tower accounts you treat — grounded in solved cycles and hot-wall saturation, not a conductivity chatbot.
- Plain-language explanations when cycles push calcite or gypsum past the deposition threshold at the hottest surface — copy the account team can take to the site
- Supervisory flags when conductivity probes on the account disagree with lab ions and mass balance
- Recommended cycle and blowdown adjustments bounded by the mineral limits and program spec you sell
- Holding-time and biological-risk narratives that feed the Legionella program you deliver, with audit trail
Model a cooling tower from an account you treat.
Bring makeup chemistry and current cycles from an account you treat. We will walk the saturation and risk picture live — 30 minutes, not a slide deck.
