Why Bunney’s for fan work
-
Right-fit fan selection for induced-draft and forced-draft towers, tuned to duty point, noise targets, and structural limits.
-
Energy-focused upgrades including aerodynamic blade profiles, variable frequency drives, and high-efficiency motors.
-
Precision installation & alignment for hubs, shafts, gearboxes, and couplings—finished with in-situ dynamic balancing.
-
Condition monitoring (vibration, thermal, amp draw, oil checks) to catch issues before they become outages.
-
Arizona-ready practices for heat, dust, hard water, and monsoon winds.
Fan options & upgrades we support
-
Axial fan assemblies: FRP or aluminum blades, adjustable pitch, stainless hardware, low-noise profiles.
-
Drives: gear or direct drive; VFD integration for demand-based speed control.
-
Stacks & shrouds: repairs and replacements to improve air velocity and reduce recirculation.
-
Controls: temperature setpoints, fan cycling logic, and interlocks that protect equipment and cut energy use.
Signs your fan needs service
-
Rising approach temperatures or loss of capacity
-
Vibration alarms, unusual noise, or frequent trips
-
High motor amps or gearbox temperature
-
Visible blade, hub, or stack damage; drift increasing
Our process
-
Assess – review performance data and inspect mechanics, electrical, and airflow.
-
Diagnose – vibration/thermal checks, blade pitch verification, and water-treatment impacts on fill/airflow.
-
Recommend – prioritized actions: immediate fixes, near-term maintenance, and capex upgrades.
-
Execute – schedule repairs or retrofits around your outage window; balance and commission.
-
Maintain – periodic cooling tower inspections and gearbox maintenance to hold the gains.
Built for Arizona conditions
-
Extreme heat: verify fan horsepower margin, oil health, and bearing cooling.
-
Dust/monsoon debris: clean and protect fill, screens, and stacks to preserve airflow.
-
Hard water: coordinate with water treatment to limit scale that drives fans harder.
FAQs
How often should towers be inspected?
Most facilities benefit from a comprehensive annual inspection plus mid-season checks. Critical assets or harsh environments may require quarterly reviews.
Do you work around production?
Yes. We coordinate with your operations team to inspect during low-load windows and can stage repairs during planned outages.
Can you test water on-site?
We perform targeted on-site checks and can coordinate lab analysis when deeper diagnostics are needed.
What if issues are found?
You’ll get a prioritized plan with clear next steps. Our crew can execute corrective work or support your in-house team.
Do you provide fan balancing and alignment?
Yes. We handle precision laser alignment and trim balancing, then baseline vibration so you can track performance.
Can upgrades reduce energy use?
Often, yes—VFDs, high-efficiency blades, and optimized pitch settings can cut power draw while maintaining cooling capacity.
