The fiber-reinforced polymer is a blended material utilized to make the FRP cooling tower used in industries today. In summation, it can resist any weather situation and withstand corrosion, waterborne bacteria, and organisms. So, if you are focused on purchasing cooling towers products, you can contact Towertech.

FRP Cooling Towers

It is made in such a way that it can persist against high wind swiftness the shocks and vibration can absorb up air from all the direction. It absorbs less power in general because of more limited area utilization.

In other words, the FRP cross-flow cooling tower is designed so that air must come into contact with water for heat loss to occur. The air aims to lower the warmth of the hot water. More of the importance is stated below:

Essential Facts of FRP Cooling Towers

• Pultrusion technology is usually most favored due to its constructional material used and its application for small cooling towers.
• FRP material needs less maintenance and gives low cost. However, reinforced concrete is still employed in large constructions.
• Different cooling towers include coaxed draft cooling towers, FRP cooling towers, Fanless filles, and a few others. You can pick the one which satisfies all your requirements.

Advantages of FRP Cooling Towers

Towetech manufactures a prerequisite range of FRP square cooling towers in India by following the technically advanced mechanism to improve the trait of products. Our collection can furnish many areas such as chemical plants, oil refiners, power stations, and building cooling.

Where is the FRP cooling tower placed?

They are primarily used in chemical factories, petrochemical manufactories, thermal plants, building cooling and air conditioning, large schools and hotels, hospitals and oil refineries, steel mills, power plants, and a few others.

The FRP type of cooling tower is possible either in the original drafts or induced drafts. Natural FRP induced draft cooling towers are outlined to move air up through the tower without fans so casually. Produced draft FRP cooling towers there depend on the fans to get rid of the motion.

What are the parts of an FRP cooling tower, and what is their purpose?

• The fills can be made of PVC or wood. The PVC is more likely to be employed in the FRP cooling tower to promote heat transfer by maximizing water and air contact. Fill can be sprinkled or film type depending on what serves best for the cooling tower.
• Frame and casing; the structure and casing of the FRP cooling tower are fiberglass reinforced plastics. Some towers have the edge and external casings, while the rest of the frame serves as the casing.
• Fans; the common types utilized are propeller and centrifugal fans. The FRP cooling towers with induced designs employ propeller fans, while both propeller and centrifuge are practiced in the forced draft cooling towers.
• Coldwater basin; this is where the water drips down from the fills. The bay sometimes has heaters, mainly during winter, to prevent freezing of the water in the basin.
• Air inlets; allows the air in to allow direct contact with the hot water for cooling.
• The FRP cooling tower has to possess louvers to block the entry of birds and rodents into the cooling tower. The louvers also reduce the amount of splash out, which limits water wastage and lowers chemical use. They are effective for keeping out direct sunlight to limit algae germination in the cooling tower container.
• Drift eliminators; the purpose of this in the FRP cooling towers is to remove water droplets from the air and minimize loss of process water. They affect the water droplets and air, forcing them to change direction suddenly, which separates the water and the atmosphere. The water flows back into the cooling tower.
• Driveshafts; function by transmitting power from the motors output shaft to the gear reducer&#;s input shaft. The driveshaft needs to be corrosion-resistant.
• Gear reduced solutions; gearboxes available for the FRP cooling tower are designed to accommodate horsepower and fan speed.

The FRP cooling towers are available in natural draft cooling towers and induced draft cooling towers. It has two different air mechanisms, out of which you can pick out the one that suits you the best.

Different frames allow you a variety of space and magnitude. From which, you can pick one of the square-shaped cooling towers for a more enhanced immensity of space.

Besides, you can pick from different color options available along with the forms. The benefits of FRP cooling towers are many, and the advantages mentioned above will provide you with some understanding of it and how it works.

So which material should you choose for your cooling tower? What are the benefits and disadvantages of each one? Read on to learn more about stainless steel VS fibreglass cooling towers.

What is a cooling tower?

A cooling tower is a specialised device that discharges heat waste into the atmosphere. This process is done by drawing cool air over the surface of the water. Small amounts of water then evaporate, which lowers the temperature of the water running through the tower. 

Cooling towers are used to lower the temperature of the circulating hot water from the condenser or any other heat exchanger. The cooled down water is then ready to be pumped around again back to the heat exchangers.

Stainless steel

Everyone understands that stainless steel is strong, durable and long-lasting. Its robust nature means that it is a low-maintenance material that retains lustre for years to come. But is this suitable for your cooling tower?

Advantages

Stainless steel is incredibly strong. This is an advantage for those who wish to put loads on the tower, such as piping, attenuators and platforms. Ladders can also be attached to the structure without fear of damage or risk to the workers using it. 

Unlike fibreglass (FRP), stainless steel won&#;t creep, sag or deteriorate. It also won&#;t lose its properties over time and deform. This is because stainless steel is more resistant to high and low pH levels compared to FRP. With proper maintenance and care, your stainless steel tower will remain as sturdy as the day it was installed. 

Your stainless steel tower will almost never crack. Being such a durable material, stainless steel isn&#;t susceptible to damage from handling or impact. In the instance that something was to hit your tower, it will dent rather than break. This means that even when partially damaged, your cooling tower will still be in working condition.

Disadvantages

In rare cases, the additional weight of a stainless steel tower can be a disadvantage. For example, when a tower needs to be mounted onto a roof, which has a very low weight limit. 

Many owners don&#;t want the expense of hiring an engineer for an engineering enquiry, or the downtime of redesigning the facility in order to crane the new tower in. In this case, an FRP tower may be a more suitable option thanks to its lightweight nature.

FRP towers are normally more cost-effective than stainless steel. However, the total project cost can be reversed once access platforms and piping are considered. An FRP tower cannot support these mechanisms, so other means will need to be invested in. 

Fibreglass reinforced plastic (FRP)

Fibreglass reinforced plastic, or FRP, is a cost-effective material that is popular among many manufacturers. Is it suitable for your cooling tower though? This depends on your circumstance and budget. 

Advantages

An FRP cooling tower is lighter than stainless steel towers. In a replacement situation where an old tower is in a precarious location &#; on a rooftop, for example &#; the dry weight of an FRP tower is light enough that it can be craned to the location needed. 

Disadvantages

However, unlike stainless steel, FRP does not resist impact very well. The same crane that is used to lift your new FRP tower into place may accidentally hit a wall or truck, causing your new tower to crack. If this happens, expensive fibreglass repairs will be needed.

Cooling towers are constantly warm, and the water is always chlorinated and exposed to damaging UV rays. This causes the FRP to &#;creep&#; &#; meaning that the material itself loses its properties and deforms over time. When this happens, the tower can start to sag with the weight of the warm water. Unfortunately, this cannot be repaired. The only solution is to replace the whole tower. 

Cold water basin: Stainless steel or FRP?

While the choice of stainless steel or an FRP cooling tower depends on your budget and situation, the cold water basin is another story.

What is a cold water basin?

A cold water basin is a device or tray-like structure underlying the cooling tower. Its purpose is to receive the cold water from the tower and direct its flow to the suction line or sump.

The cold water basin is constantly filled with water. This means that the materials used for the basin will be exposed to more chemicals and varying pH water levels than any other part of the tower. So it&#;s crucial that the material chosen is strong, durable and robust.

Stainless steel or FRP?

While it&#;s possible to replace the top or side of your tower, it&#;s often economically impractical to repair or replace a damaged cold water basin. So choose stainless steel for your basin. Stainless steel is a more reliable material, so it&#;s less prone to leaks, cracks and deterioration. 

While a full stainless steel tower is the best option, sometimes it isn&#;t always viable. In that instance, having at least the cold basin in stainless steel and the rest in FRP will provide the benefits of stainless steel in the most critical area.
