REPAIR AND RECONSTRUCTION
Just like a car, cooling towers need maintenance at scheduled intervals or you risk potential catastrophic failure. Should you need service on parts or repairs, Midwest Machinery works on all makes and models of towers, factory assembled or field-erected.
FILL REPLACEMENT
Scale and algae buildup, brittle from UV attack, corroded supporting tubes, and ice damage are only some of the conditions that affect your fill and the cooling tower efficiency. Typically, service of PVC fill media is required every 10 to 15 years.
COLLECTION BASIN REFURBISHMENT
Cooling towers galvanized collection water basins can accumulate silt and sludge, and can be damaged by corrosion and chemical attacks that deteriorate its walls. In the best scenario, a cooling tower basin lasts for 15 to 20 years without requiring a basin coating.
GEARDUCER
Oil level, leaks and quality, backlash issues, endplay inadequacies, deposits outside of the case, and tightness of all the hardware connecting the Geareducer to the support have direct impact on the cooling tower performance. Geareducers should be examined every 3 to 6 months.
NOZZLES
Nozzles can get clogged and present normal signs of wear or loss of material as consequence of corrosion or erosion. Maintenance procedures include checking if they are in place, working properly, and correctly connected to branch pipe or distribution basin floor.
DRIFT ELIMINATORS
Debris in the air passages of drift eliminators, bad seals conditions, UV attack, and frames and components improperly installed will affect the airflow of your tower, decreasing performance. Drift eliminators should be checked every 6 months.
FANS
Corrosion and erosion in fan blades or broken and missing blades, bad connections between the blades and hub, and the tightness of the bushing between the hub and shaft can cause more problems than just vibration. Tech support is necessary not only for fans, but also for the fan deck and the fan cylinders.
LOUVERS
Louvers need to be in place and have no signs of deterioration of the base material, or scale buildup and biological growth. Louvers supports need to be in good condition, and the connections between the louvers and the tower need to be constantly observed. ACB louvers are supposed to be replaced every cooling tower startup.
STAIRWAY, LADDER AND HANDRAIL
The tower structure is important for safety purposes. Wood decay and steel corrosion on the stairway, or loose treads, handrails, or deteriorated stringers could potentially cause accidents. Tightness of bolted connections and hardware condition and welds need to be verified on a regular basis.
MAINTENANCE AND COOLING TOWER CLEANING
Regular cleaning and quality water will dramatically prolong the life of a cooling towers. We can advise or service any cooling tower to maintain maximum longevity in the field.
FILL CLEANING
It is important to understand that scale formation on a cooling tower fill is the natural occurrence of a tower operation, which means that in moderation it will not affect the performance of the equipment.
Salts and debris that are inside the water stay behind due to the fill and the louvers, and that is good sign, meaning that your tower is performing as it is supposed to.
However, cooling tower fill must be cleaned twice a year in order to control the scale buildup. The fill is the heart of a cooling tower, and excessive scale can obstruct water passage and cause the equipment filter to clog, eventually causing the equipment failure.
WATER TREATMENT
In crossflow towers the water flows vertically through the fill while the air flows horizontally, across the flow of the falling water. Cooling towers attract all kinds of airborne debris, and potential contaminants that enter the cooling tower are the ideal environment for bacterial growth and the formation of biofilm.
Biofilm in a cooling tower is one of the biggest concerns in our industry now, because of its contribution to increased levels of legionella, a bacteria that lives in hydronic systems but can be deadly dangerous if not under control.
There are several types of cooling tower water treatment solutions available in the market, and they can be either chemical or non-chemical. Regardless of your option, having an efficient water treatment program will not only prevent bacterial growth, but will also increase the lifetime of your equipment.
