Rialto Commercial Legionella Prevention for Cooling Towers

Engineering‑First Legionella Strategy for Cooling Towers

Our approach starts with engineering discipline and ends with measurable results. We focus on controlling the conditions that allow Legionella to thrive—stagnation, nutrients, biofilm, and uncontrolled temperature—while maintaining cooling performance. Every program is designed to be practical, auditable, and aligned with ASHRAE 188 and current CDC guidance.

What’s Included in Your Program

• Comprehensive risk assessment of your cooling tower system, makeup, and blowdown
• Custom Water Management Plan (WMP) with clear roles, monitoring, and corrective actions
• Mechanical cleaning, descaling, and biofilm removal; basin and fill maintenance
• Disinfection protocols: oxidizing/non‑oxidizing biocides (EPA‑registered) and dispersants
• Side‑stream filtration to capture suspended solids and reduce nutrient load
• Drift eliminator evaluation and upgrades to minimize aerosolized droplets
• Automated controllers for biocide feed, conductivity, and pH; BMS integration
• Routine on‑site testing (Langelier index, oxidant residuals, ATP) with trend analysis
• Accredited laboratory Legionella culture testing (ISO 11731) when indicated
• Event‑driven response: shock disinfection and post‑remediation verification
• Complete documentation: logs, sampling records, corrective action reports, and signage

Our 6‑Step Process

1. Assess – We map your system, review schematics, and identify risk drivers (hydraulics, dead legs, heat load, historical issues).
2. Plan – We build a site‑specific WMP with monitoring points, frequencies, limits, and response actions.
3. Stabilize – Initiate cleaning, descaling, and disinfection; optimize cycles of concentration, filtration, and bleed.
4. Control – Implement biocide program, dispersants, and biofilm control; verify with routine testing.
5. Automate – Add controllers, remote alerts, and data logs for consistent dosing and compliance evidence.
6. Verify – Periodic internal audits, data reviews, and third‑party lab testing as indicated by risk.

Performance and Energy

Cleaner towers exchange heat more efficiently. By removing scale and biofilm, tightening cycles of concentration, and balancing chemistry, we help lower energy consumption, extend equipment life, and reduce unplanned downtime.

Documentation That Stands Up to Review

From monitoring logs and dosing records to lab reports and corrective actions, we maintain a complete paper trail. Need to brief leadership or pass a third‑party review? We package your data, trends, and verification steps in a clear, professional report.

AC PRO Supply Advantage

As an AC PRO partner, we move fast when you need controllers, sensors, filters, drift eliminators, and ancillary tower components. Reliable availability means less waiting and more uptime for your operation.

Service Area

We serve Rialto and nearby Inland Empire communities, plus Los Angeles County and adjacent regions including Orange County, Ventura County, and Western Riverside County. Multi‑site portfolios welcome.
