Informações de Ventilação para sistemas de resfriamento

Ventilation systems are systems whose purpose is to perform the exchange of air in the environment where it operates. Ventilation systems for cooling are those that perform this exchange of air in an environment whose ultimate goal is thermal exchange.


What are the applications of cooling system fans?

At FanTR, there are several fan models that are applied in the following cooling systems: cooling towers, air coolers and air-cooled condensers. These ventilation systems are commonly used in the following markets: Refineries, steel mills, metallurgical plants, aluminum production, petrochemical plants, pulp and paper, energy (thermoelectric plants), oil and gas, food industry, among others. These are industrial processes with high heat emissions where system cooling is necessary to ensure the operation of the manufacturing process in these units.


Which model is most suitable for your use?

Access the buttons below and understand a little more about the characteristics of the axial fans available in our product line.


Aluminum Fans:

Our line starts with aluminum fans that have lower cost and lower efficiency
when compared to models that use composite material. There are two models: FAS360 and FAS490 that have different blade widths. The difference between the two models is that the FAS490 has a larger blade width, and it’s used at lower speeds for applications with lower noise emission.

FanTR produces aluminum fans up to 13 feet (4 meters), which can be used in coolers, cooling towers and condensers, where the energy cost does not impact the customer's operation, and also when the goal is a lower acquisition cost and quick delivery.

These smaller towers are normally used in the food industry, sugar cane production, medium and small industries, and in air conditioning systems in large buildings, such as shopping malls and hospitals.


Fans with Composite Material Blades:

Standard Fans: there are 3 models available: CR, NCR and TEP.

The CR Fan is the entry model of the composite line, and can reach up to 36 feet (11 meters) in diameter, but are usually used in applications up to 14 feet (4.3 meters) in diameter. These fans should be used instead of aluminum fans in air coolers and cooling towers when higher system efficiency and lower total cost are desired considering the gains in equipment operation.

Next is the NCR model, which is an evolution of the CR line and replaced this
first model in fan applications above 14 feet (4.3 meters). It has a more modern and efficient design than its predecessor CR, and can reach up to 42 feet (12.8 meters) in diameter.

The TEP model can be used in the same applications where the NCR is used, but because it has a larger width, it is recommended for applications with lower rotations or when you want to use fewer blades.


Low-noise fans: there are 2 models available: SLSF and STEP.

The SLSF is a super low-sound axial fan that can reach up to 13 feet (4 meters) in diameter. It is usually used in coolers, condensers, and cooling towers. This product should be chosen when extremely low noise emission is desired, for example in hospitals and urban areas in general. For this reason, it has a higher acquisition cost than the standard versions.

The STEP model is the model with FanTR's largest width blades. These fans can reach up to 38 feet (11.6 meters) in diameter and are used at low rotations. It can be used in cooling towers and also on air cooled condensers, when sound emission is a customer's restriction. Its main markets are energy and industrial.


Special fans: there are 2 models available: FLN and the HA line.

The FLN line is an experimental line that uses the "noise cancel" technology of
noise cancellation by vortex generation at its trailing edge. It is mainly used in
special applications as a CR replacement for low noise.

The HA line basically consists of CR and TEP fans, whose hub and mounting kit
are adapted to withstand high corrosion environments. They are mainly used in zinc processing plants and with high chloride and/or fluoride concentration in the tower water.


Direct Drive: The Direct Drive system comes as a more efficient solution to replace the pulley and belt transmission system widely used in air coolers. Despite being cheaper, the pulley and belt system generates a high maintenance rate with constant equipment downtime. Our engineering team has developed a solution to replace this system by a direct drive, which increases its robustness and reliability, bringing maintenance and intervention rates down to almost zero. Thus, ensuring the continuous availability of the equipment and greater predictability of the predictive maintenance system.
