Generator Auxiliary Systems

Gearboxes
Gearboxes are available in a number of different reduction rates and styles to support the variable strengths and fan speeds of cooling towers.

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.

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
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
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
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.

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.

Horizontal Remote Radiator
Separation of Cooling System: In a remote radiator setup, the cooling system is separated from the generator and placed in a different location. This allows for flexibility in positioning the radiator, which can be advantageous in situations where there is limited space around the generator or where noise reduction is a concern.
Coolant Circulation: The remote radiator is connected to the generator's cooling system through coolant lines or hoses. The coolant, typically a mixture of water and antifreeze, circulates between the generator and the remote radiator, carrying heat away from the generator's components.
Heat Dissipation: The remote radiator operates on the same principle as a traditional generator radiator. The coolant flows through channels or tubes within the radiator, and ambient air passes over the radiator's fins. The movement of the air facilitates heat transfer, allowing the coolant to release heat and cool down.
Fan or Blower: Remote radiators may incorporate fans or blowers to enhance airflow through the radiator. These fans can be located either at the generator end or the radiator end, depending on the specific design. The fans help ensure proper airflow and efficient heat dissipation from the coolant.
Piping and Connections: The coolant lines or hoses connecting the generator and remote radiator need to be properly sized and routed to facilitate the flow of coolant. Adequate insulation may be required to minimize heat loss from the coolant during transfer.
