Preventive service that protects uptime, safety, and water/energy use
Bunney’s Inc. helps Arizona facilities keep their cooling towers reliable, efficient, and compliant. Our technicians combine disciplined inspections, deep-cleaning, and targeted mechanical repairs with a right-sized water treatment program: all tailored to local conditions like hard water, dust, extreme heat, and monsoon season. The result: fewer unplanned outages, lower operating costs, and longer asset life.
What we service
-
Crossflow and counterflow towers, induced/forced draft
-
Packaged and field-erected units (steel, fiberglass, concrete)
-
Fans, gearboxes, drives, motors, bearings, couplings, basins, fill, drift eliminators, distribution decks and nozzles, strainers, louvers, make-up/float assemblies, and controls
Our cooling tower maintenance program
Inspections & performance checks
-
Visual and mechanical inspection (structure, basins, hot deck, fill, eliminators)
-
Drive system checks (alignment, belt/gearbox condition, lubrication, vibration)
-
Flow, approach temperature, and kW/ton snapshots to benchmark efficiency
-
Written report with photos, prioritized actions, and parts list
Cleaning, disinfection & descaling
-
Basin, fill, and distribution cleaning to remove biofilm, scale, silt, and debris
-
Disinfection aligned with ASHRAE 188 and local AHJ guidance
-
Descaling where hard-water deposits reduce heat transfer
Water treatment & monitoring
-
Scale, corrosion, and microbiological control based on site water chemistry
-
Conductivity/pH monitoring, cycles-of-concentration optimization, blowdown control
-
On-site testing with optional lab analysis; monthly trending and compliance logs
Mechanical repairs & retrofits
-
Fan blade service, balancing, gearbox rebuilds, shaft/coupling replacements
-
Nozzle and distribution upgrades for even coverage
-
Fill and drift eliminator replacements to restore thermal performance
-
VFDs and controls tuning for part-load efficiency and noise reduction
Seasonal services
-
Startup commissioning (spring), shutdown preservation (fall)
-
Monsoon readiness: debris management, strainers, and over-splash containment
-
Heat-season checks on bearings, belts, and oil to prevent mid-summer failures
Why it matters
-
Lower energy use: Clean heat-exchange surfaces and tuned airflow reduce fan and pump power.
-
Water savings: Optimized cycles and controlled blowdown cut water and chemical spend.
-
Asset life: Proactive cleaning and lubrication slow corrosion and wear.
-
Health & compliance: Documented water treatment and disinfection help manage Legionella risk.
-
Fewer emergencies: Condition-based repairs prevent costly mid-season outages.
Built for Arizona conditions
Hard water, dust, high UV, and intense heat accelerate fouling and scale. Our Arizona-focused plans increase cleaning frequency, select UV-stable materials, protect coatings, and tune cycles of concentration to local water quality—backed by real-world data from facilities across the state.
How we work
-
Site walk & baseline test – inspect, measure approach temperature, review water logs
-
Plan & quote – phased, prioritized scope with options (good/better/best)
-
Execute safely – LOTO, confined-space procedures, chemical handling protocols
-
Verify performance – post-service readings, photos, and maintenance records
-
Ongoing care – PM calendar (monthly/quarterly/annual) with CMMS-ready reporting
Industries we support
Manufacturing, power & utilities, food & beverage, healthcare, data centers, universities, and commercial campuses—serving businesses across Arizona.
FAQs
How often should a cooling tower be serviced?
Most sites benefit from monthly checks, quarterly mechanical inspections, and semi-annual deep cleaning/disinfection. Dusty locations or critical facilities may move to bi-monthly or quarterly cleanings during peak season.
Can you perform work without shutting down my system?
Often, yes. We schedule low-load windows, stage temporary filtration, and isolate equipment to keep cooling available while we service individual cells or components.
Do you handle water treatment and Legionella risk management?
Yes. We set up scale/corrosion/microbiological control, document dosing and testing, and align with ASHRAE 188 practices. We provide on-site testing and can coordinate third-party labs when needed.
What efficiency improvements are typical after cleaning and tune-up?
Sites commonly see lower approach temperatures, reduced fan amps, and higher allowable cycles of concentration. We document before/after kW/ton and water use so you can quantify savings.
Which brands and tower types do you service?
All major OEMs and configurations—crossflow, counterflow, induced/forced draft, packaged and field-erected—plus gear- and belt-driven systems with or without VFDs.
