Preventative Maintenance Inspections

Your cooling tower works hard year-round — make sure it’s ready when you need it most.
With preventative maintenance inspections from Great Lakes Cooling Towers Inc. (GLCTI), our team of professionals will visit your site to assess the tower at the inspection level of your choosing. During the visit, we’ll complete minor maintenance tasks within the allotted timeframe and provide a detailed report outlining:

• The condition of key components

• Estimated remaining lifespans

• Any areas of concern requiring future attention

Neglecting preventative maintenance can lead to costly and hidden damage. A single broken nozzle or disconnected lateral pipe can silently channel water through your fill, rendering sections of your tower ineffective. A cracked mechanical girt or loose support within the structure can cause excessive vibration, leading to severe — and often irreversible — damage to your mechanical system.

Best industry practice recommends professional inspections every 6 to 12 months to ensure your tower operates safely and efficiently.
Planned inspections during scheduled outages are always better than an unexpected shutdown.

“If you don’t take time for your equipment — it will make you take time.”

Inspection types

Level One:

Visual. External Inspection tasks include, but not limited to general cleaning, signs of collapsed or missing fill, casing, louvers, louver doors, fan cylinders, distribution piping, pipe supports, stairs, staircases, doors, hatches, handrails, ladders and hot water basin nozzles (crossflow towers). Unusual mechanical vibrations and noises should be noted and reported.

Level Two:

Visual and Non-Destructive Examination (NDE) Moisture testing, defect limit measurements, and digital photography. External Inspection, Internal decay probing,providing measurement of: fan blade pitches, fan blade tip clearance, 100% visual inspection of the exterior of the tower and all readily accessible structural members and connections, fan cylinders, torque tubes, oil lines, wind blocks, plenum area, catwalks, platforms, fan decks, hotwater basins, distribution system, wind walls.

Level 2 inspections are typically conducted while the cooling tower is in service, but flow is shut off to the cell being inspected.

Level Three:

Full inspection tasks include removing portions of fill and drift eliminators for access to most components of the structure, internal decay probing, minor cleaning, density testing (depending on the temperature).
