Commercial Legionella Prevention for Cooling Towers in Orange

Cooling towers are vital to comfort and process cooling, yet their warm, recirculating water can create conditions where Legionella may proliferate if systems are not engineered and maintained correctly. Our mission—healthy air and water for healthy lives—drives a comprehensive program that reduces risk while improving reliability and lifecycle cost.

What we deliver

• Risk assessment specific to your site, load profile, tower design, and drift control
• ASHRAE 188–aligned Water Management Program (WMP), roles, and response matrix
• Automated biocide/non‑oxidizing biocide control with real‑time monitoring
• Side‑stream filtration and solids management to limit biofilm and fouling
• Scheduled deep cleaning, descaling, and shock disinfection
• Startup, shutdown, and offline layup protocols to prevent stagnation risk
• Certified lab testing coordination with clear reporting and trend analysis
• BMS integration (BACnet/Modbus) and alarms for out‑of‑spec conditions

Our step‑by‑step process

1) Survey and Baseline: We audit tower condition, drift eliminators, basin hygiene, fill condition, dosing equipment, make‑up water, and blowdown strategy. We review logs and any previous sampling results to establish a baseline.
2) WMP Creation: We develop a written plan with monitoring points, frequencies, targets, verification/validation, and escalation protocols aligned with ASHRAE 188 and CDC guidance.
3) Controls and Filtration: We implement or optimize automated dosing, side‑stream filtration, and corrosion/scale control suited to your water quality and load profile.
4) Cleaning & Disinfection: We schedule mechanical cleaning and shock disinfection, including passivation after chemical cleaning when appropriate.
5) Monitoring & Documentation: We trend key parameters, coordinate certified lab Legionella testing, and keep audit‑ready logs and reports.
6) Continuous Improvement: We review monthly/quarterly performance, adjust setpoints, and refine maintenance to reduce risk and cost.

Gree expertise that scales with your system

Factory‑trained by Gree (China), our engineers integrate Gree VRF/chiller equipment with cooling tower controls for steadier condenser water temperatures, improved load matching, and more stable water chemistry. We also bring factory training from Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), and Haier (China), ensuring advanced diagnostics and seamless BMS integration across mixed OEM environments.

Technology highlights

• Automated chemical feed with validated sensors and interlocks
• Side‑stream sand or multi‑media filtration for solids reduction
• High‑efficiency drift eliminators and nozzle optimization
• Remote monitoring, alarm notifications, and data trending
• Energy‑aware control strategies that balance hygiene and efficiency

Compliance, documentation, and audits

We align with ASHRAE 188 and the CDC Legionella toolkit, produce clear SOPs, logs, and response checklists, and support interactions with local authorities and third‑party auditors. While no vendor can promise zero risk, our verification and validation processes make your program defensible, measurable, and continuously improving.
