Six Reasons FRP Products are Used in Cooling Towers - Strongwell

Cooling towers are an essential part of many industrial processes, as they ensure the efficient removal of excess and/or waste heat generated during a variety of manufacturing processes. Most cooling towers were traditionally constructed of wood, but considering water's long-term effects on wood, it isn't an ideal structural material. Here are six reasons why fiber reinforced polymer structural shapes (FRP) are the best products out of which to build cooling towers:

Corrosion Resistance

Cooling towers are exposed to water and chemicals, which can be corrosive to traditional materials. Fiberglass, also known as fiberglass reinforced polymer (FRP) or glass fiber reinforced plastic (GRP), has excellent resistance to corrosion, making it an ideal material choice for cooling tower construction. It can withstand the harsh conditions and extended exposure to moisture, chemicals, and UV radiation without degrading like most traditional materials would.

Lightweight and High Strength

Fiberglass is a lightweight material that offers a high strength-to-weight ratio. This makes it easier to transport, handle, and install cooling tower components. Despite its lightweight nature, fiberglass is structurally sound and can be engineered to withstand the loads and stresses encountered in cooling tower applications.

Design Flexibility

Fiberglass can be molded into various shapes and sizes, allowing for flexibility in cooling tower design. It can be easily formed into intricate geometries and custom configurations to optimize performance and efficiency. This flexibility enables manufacturers to create cooling towers that are tailored to specific project requirements and space constraints. Traditional wood cooling towers used 2x4, 2x6, and 4x4 treated lumber, as well as plywood for decking. Pultruded FRP channels, square tubes, and decking are a simple one-for-one replacement geometrically for those traditional wooden sizes.

Thermal Insulation

Fiberglass possesses inherent thermal insulation properties. It helps reduce heat transfer, minimizing the loss of cooling efficiency in the tower structure. This insulation capability contributes to energy savings and improved overall performance of the cooling system.

Longevity and Durability

Fiberglass has a long service life and requires minimal maintenance. It is resistant to rot, rust, and degradation, ensuring the durability of the cooling tower over an extended period. Fiberglass cooling towers are known for their longevity and can withstand harsh environmental conditions without significant deterioration.

Cost-effectiveness

While the upfront cost of fiberglass cooling towers may be higher compared to some other materials, their long-term cost-effectiveness comes from reduced maintenance needs, longevity, and energy efficiency. The low maintenance requirements and extended service life help offset the initial investment.

Overall, fiberglass offers a combination of corrosion resistance, strength, design flexibility, insulation properties, longevity, and cost-effectiveness, making it a suitable material for cooling tower construction.

10 Things you need to know about FRP Cooling Tower

Cooling towers are generally associated with major power stations and businesses. FRP cooling towers revisited the technology to develop a cooling tower in package size. FRP is Fiberglass reinforced plastic; the substance is corrosion-free and heat resistant. FRP is long-lasting too. Because they are constructed beforehand, FRP cooling towers are transported to the target building from the producer. They are more suitable for installations with minimal thermal rejection requirements because of their compact nature.

The FRP square cooling tower is designed with PVC filling devices in the form of honeycombs and drift disposers. This helps to maximize efficiency and economy. You also have a fan and spray nozzle-driven motor for little loss of drift.

Type

The kind of FRP cooling tower varies by draft. There are three techniques, but proprietary designs from certain manufacturers might be available on the market. These are the kinds

  • Forced Draft: the fans in the cooling tower at the end of the tower are fitted. The fans propel the air in the filling stack.
  • Induced Draft: fans are mounted on the top of the tower. They work by drawing air into the filling stack.
  • Natural Daft: these refrigerating towers employ a natural airflow up the stack. The towers are wide and costly. They are used largely in power stations.

Design

FRP cooling towers differ in design depending on the cooling principle mechanism, as explained below.

  • Cross Flow
    The water and air is flo
  • wing in this type of FRP cooling tower. The heat dissipation material is close to the collection basin, which reduces the noise from the water that drops. It features a basic design and has less room on the floor. Crossflow FRP cooling towers provide additional long-term advantages.
  • Counterflow
    The air and water mixed in this sort of FRP cooling tower. The water is dropping, and vertically the air is rising. The heat exchange is very efficient owing to its complicated construction. It has maintenance difficulties.
  • Closed Loop
    The operation of the closed-loop system is similar to that of the cooling system. It is in a closed tube system with hot water. When the water flows over closed rods, evaporation takes place.
  • Open Loop
    The hot water is pumped to a top tank via the open-loop system in the FRP cooling tournament. A sequence of fills then drives the water down, while air is driven up through them by a fan. The water is recirculated to the FRP cooling tower system by evaporation.

Specifications

Various criteria are used for FRP cooling towers. The parameters are used to determine the cooling water flow rate and other aspects such as power usage.

  • The capacity of a swamp or basin utilized for water gathering.
  • Operating weight to calculate the location of the FRP cooling tower.

Functionality and options

The following functions and choices are available for FRP cooling towers.

  • Corrosion-resistant substances are used in the towers for water protection and chemicals.
  • A control panel is also included in the FRP cooling towers.
  • Cooling towers are fitted with an electric heater for usage in cold areas to avoid freezing. To prevent freezing, you can also have an internal storage tank in place of the normal pond.
  • The ventilator and engine should have closed coils for longer life.
  • Portability

The most sought-after cooling towers are fibreglass reinforced plastic (FRP). Here we will tell you 10 things you should know about FRP Cooling Towers.

Light Weight: Fibreglass is formed of polymers and is very lightweight, which is also passed on to cooling towers built of FRP. The massive cooling towers built of FRP are therefore not as hefty as they seem.

Easy Transportation: Due to the small weight of FRP cooling towers, they are very easy to move and manage. In a car break-out, towers without heavy gear can be moved from one vehicle to another.

Easier to install: The lightweight feature also makes installing easy. However, besides this, the components in the FRP cooling towers may be fitted and installed without the need for heavy machinery.

Leakproof: One of the most critical features must be leakproof for any cooling tower. FRP is composed of resin and fiberglass, which automatically proves leak resistant.

Resistant to weather: Cooling towers are installed open and, because of natural climatic conditions, they are prone to wear and tear. FRP cooling towers are suitable for locations with high-temperature conditions and can endure harsh climatic conditions.

Anti-corrosive: Any object that comes into frequent touch with water must be rust-resistant. FRP is a fantastic medium. FRP tower coolers are corrosion resistant.

Unaffected by Microorganisms: Continuous water usage leads to the formation of micro-organisms like algae and bacteria, which are not impacted by FRP cooling towers because of their lack of an environment that encourages microorganism growth.

Sturdy: FRP cooling towers consist of polymers and resins that make the cooling towers a lasting solution, ensuring robustness for the final result.

Easy to maintain: FRP cooling towers offer little overhead maintenance because of various properties such as corrosion and meteor resistance. These qualities guarantee that the maintenance required is reduced due to external damage. This reduces maintenance requirements and reduces maintenance costs.

Long Duration: FRP Water Cooling Tower lasts for a long time. This is not an autonomous feature; many other features support this. However, the reality is that FRP cooling towers survive a long time, whatever the reason.
