9 Essential Parts And Components Of Cooling Towers

Date: May 8, 2017

There are several elements that work together in order to create a functioning, efficient cooling tower. Many of these elements will need to be repaired or replaced in the cooling tower’s lifetime. Here is a closer look at some of these parts, including the gearboxes, fill media, drift reducers, nozzles, fans, and more.


Gearboxes are available in a number of different reduction rates and styles to support the variable strengths and fan speeds of cooling towers. Cooling tower producers typically allow clients to purchase new gearboxes or employ skilled experts who can restore or renew a gearbox with original equipment manufactured (OEM) parts. Amarillo Gear Service uses OEM and all american manufactured parts when restoring gearboxes.

Fill media

Fill media is an essential cooling tower element. Most modern cooling towers effectively use plastic fill media for maximum water evaporation. Water is dispersed through the fill, which flattens out into a thin film with a large surface area. This procedure makes it possible for excess moisture and heat to rapidly evaporate.

The key components of selecting fill media include TSS (Total Suspended Solids) levels, intended use, water composition, and vulnerability to contamination. The two primary kinds of fill media are film-style, which distributes water across a flat layer, and splash-style, which breaks up moisture. Crossflow and counterflow fill media are other types of materials available for specialized cooling towers.

Drift reducers

Drift reducers are important cooling tower parts that work to eliminate water droplets in the air and recycle the moisture for operational processes. They do this by abruptly forcing the moist air in another direction, separating the moisture from the air and redirecting it to another part of the cooling tower.


Nozzles are most commonly found in crossflow cooling towers, which harness the power of gravity to distribute water. In these kinds of systems, water is lifted up to dispersal reservoirs above the fill media. Gravity then pulls the water through the fill media through nozzles in the bottom of the reservoirs.


Fans serve the purpose of forcing or pushing air throughout a cooling tower. The fans must be durable enough to stand up to the caustic atmosphere in which they work. They are often pretty noisy, but there are quieter cooling tower fans available. This equipment can be found in counterflow, crossflow, and other mechanical draft cooling towers. Natural air flow cooling towers have no use for fans, as they use natural drafts and water cooling techniques.


Driveshafts are tailor-made to transfer energy from a cooling tower engine’s outflow shaft into the intake shaft of the gear reducer. This process generates a rotating force that turns the fan blades. Driveshafts are available in lengths spanning from two feet in compact AC towers to more than 20 feet in heavy-duty industrial towers. Driveshafts need to be rust-proof because of the corrosive atmospheres they function in.

Air intake louvers

Air intake or inlet louvers prevent the sun’s rays from penetrating the water reservoir, which stops mold and algae from forming and reduces chemical expenses. Air intake louvers also prevent water from splashing out of the reservoir. This benefit reduces the amount of water and chemicals needed, while making the reservoir itself easier to access and remove. Counterflow air intake louvers are known to develop scales if they are not properly cleaned and taken care of. This issue restricts air circulation and decreases the effectiveness of the entire system.

Electric float valves

Electric float valves are low-maintenance components that maintain the functionality of your cooling tower for an extended period of time. In most cases, you can find electric float valve kits that come with floats, arms, and valves to accommodate a variety of different tasks.

Reservoir heaters

Reservoir heaters prohibit the water from freezing in a cooling tower reservoir during winter. These components are suitable for use with a variety of commercial cooling tower brands, including BAC and Evapco. Carrying both CSA and UL ratings, BAC reservoir heaters are made with tough copper heating elements that last.
