What We Maintain & Test
Cooling Towers – Fill/media cleaning and replacement, drift eliminators, nozzle/distribution tuning, gearbox/motor/fan service, coatings and leak remediation. See Cooling Tower Repair & Maintenance and Cooling Tower Renovations & Repair.
Condensers & Heat Exchangers – Tube cleaning, eddy-current/IR checks (as specified), leak detection, gasket and baffle service, flow balancing.
Pumps, Motors & Drives – Alignment, vibration analysis, seal/bearing replacement, motor testing, and VFD optimization.
Valves & Piping – Packing/seat repairs, actuator calibration, flange/gasket replacement, corrosion mitigation. (See mechanical services.)
Instrumentation & Controls – Verification of temperature, flow, and level devices; alarms and interlocks testing for safe operation.
Water Chemistry & Treatment Support – Scale/corrosion/biofouling control, blowdown optimization, and documentation to protect equipment and conserve water.
Maintenance Program (What’s Included)
-
Assessment & Monitoring – Visual/IR inspections, performance trending (approach temperature, flows, vibration), and chemistry checks.
-
Preventive Tasks – Cleaning (fill/tubes), lubrication, tensioning, filter/strainer service, fastener and electrical checks.
-
Predictive Actions – Vibration and temperature trend reviews, oil/grease condition (where applicable), and early-warning findings.
-
Corrective Work – Repairs, replacements, and upgrades scheduled during outages to minimize impact.
-
Documentation – Photos, readings, test results, and recommendations for next intervals.
Planning an outage or retrofit? We phase scopes to keep generation online where possible and coordinate closely with your control room.
Arizona-Specific Considerations
-
Extreme heat: Elevates thermal load—prioritize airflow, distribution, and condenser cleanliness; verify fans/VFD settings before peak season.
-
Hard water & dust: Accelerate scaling and fouling—pair cleaning cycles with distribution tuning and drift/filtration improvements.
-
Monsoon moisture: Protect electricals, coatings, and drainage; inspect seals and louvers pre-season.
Signs Your Cooling System Needs Attention
-
Rising condenser backpressure or approach temperature
-
Increased makeup water, drift, or visible leaks
-
Fan/gearbox vibration, motor over-amps, or abnormal noise
-
Fouled fill or tubes, poor distribution, or hot spots on IR
-
Frequent chemistry alarms or uncontrolled blowdown
