Evapco Cooling Tower Maintenance

Here’s a comprehensive maintenance guide for an EVAPCO cooling tower to ensure optimal performance, longevity, and safety. This checklist applies to closed-circuit, open-circuit, and hybrid EVAPCO towers.

Evapco Cooling Tower Maintenance Guide

1. Evapco Cooling Tower Maintenance - Daily Maintenance

✅ Evapco Cooling Tower Maintenance - Visual Inspection

* Check overall tower condition (no leaks, corrosion, or damage)

* Ensure fan, motor, and drive system are operating smoothly

* Confirm proper water flow and no dry spots on fill

* Observe water level in the cold water basin (adjust float valve if needed)

✅ Evapco Cooling Tower Maintenance - System Operation

* Verify operating temperature meets design conditions

* Listen for unusual noise/vibration from fan or motor

* Check spray pattern uniformity from spray nozzles

2. Evapco Cooling Tower Maintenance - Weekly Maintenance

Evapco Cooling Tower Maintenance - Water Quality

* Test and record water chemistry (pH, conductivity, hardness)

* Inspect for signs of scale, corrosion, or biological growth

* Confirm chemical treatment system is working properly

✅ Evapco Cooling Tower Maintenance - Mechanical Components

* Inspect fan blades for dirt buildup or damage

* Check tightness of fan, motor, and support bolts

* Inspect belt tension and alignment (for belt-drive systems)

3. Evapco Cooling Tower Maintenance - Monthly Maintenance

✅ Evapco Cooling Tower Maintenance - Drift Eliminators & Fill

* Inspect for debris, algae, or scaling

* Clean if necessary using non-corrosive cleaner and water

✅ Evapco Cooling Tower Maintenance - Strainers & Nozzles

* Remove and clean strainers

* Check nozzles for clogging and clean or replace if needed

✅ Evapco Cooling Tower Maintenance - Drive System

* Lubricate bearings (if applicable, per EVAPCO’s instructions)

* Check motor amperage and voltage

4. Evapco Cooling Tower Maintenance - Quarterly / Semi-Annual Maintenance

✅ Evapco Cooling Tower Maintenance - Deep Cleaning

* Drain and clean cold water basin thoroughly

* Flush system with clean water

* Remove and clean fill and eliminators if heavy fouling observed

✅ Evapco Cooling Tower Maintenance - Inspection

* Inspect coil (closed-circuit) for fouling or scale

* Clean with coil cleaner and low-pressure water spray

* Check all access doors and gaskets

5. Evapco Cooling Tower Maintenance - Annual Maintenance

✅ Evapco Cooling Tower Maintenance - Major Inspection

* Inspect fan motor insulation and bearings

* Check structural components for rust or corrosion

* Repaint or repair damaged areas

* Inspect all piping and valves for leaks

✅ Evapco Cooling Tower Maintenance - Winter Preparation (if applicable)

* Drain basin and piping if tower is shut down

* Inspect and test basin heater and controls

6. Evapco Cooling Tower Maintenance - Water Treatment

* Maintain biocide and anti-scale program

* Work with water treatment specialist to maintain:

 * pH: 6.5 – 8.5

 * Conductivity per EVAPCO design

 * Chlorine < 1 ppm when running

7. Evapco Cooling Tower Maintenance - Safety Precautions

* Lockout/tagout before maintenance

* Wear PPE (gloves, goggles, respirator if chemical cleaning)

* Use EVAPCO-approved cleaning agents only
