Pultruded Cooling Tower

A pultruded cooling tower is a modern, engineered structure designed for efficient heat dissipation in industrial and commercial processes. This cooling tower is constructed using pultruded fiberglass reinforced plastic (FRP), a composite material created by drawing continuous fiberglass strands through a resin bath and then shaping them in a heated die. The result is a structurally strong and lightweight core for the cooling tower. The structure typically includes pultruded FRP beams,columns and panels, complemented by robust fan decks,casing and drift eliminators made from FRP or corrugated FRP sheets. Stainless steel or hot-dip galvanized hardware is used for assembly, ensuring resistance to environmental stress and mechanical loads.

Pultruded cooling towers offer optimal thermal performance, precision-engineered airflow design, and modular construction for easy installation and scalability. The towers are available in various configurations such as counterflow and crossflow designs and can be customized with film fill or splash fill media to suit specific process requirements.

Pultruded cooling towers are widely recognized for their structural stability,consistent performance and adaptability to different water qualities like sea water and hard water.

The NATIONAL NPCT Series Counterflow Cooling Towers are field assembled, heavy duty cooling solutions that can be engineered with cell sizes up to 18 x 18 meters, accommodating water flow rates as high as 5000 m³/hr per cell.

The pultruded FRP structures of NATIONAL NPCT Cooling Towers are fully assembled using stainless steel bolts,nuts and washers. Pultruded FRP is widely recognized as an ideal construction material for cooling towers,as it does not corrode, rust or deform even in the most demanding environments.

Components of Pultruded FRP Cooling Towers:

Tower Structure

The tower structure is built from pultruded FRP beams and columns, providing a lightweight, corrosion resistant and high strength framework. It holds all components in place and withstands harsh weather over time.

Mechanical Equipment

This includes the fan, gearbox,drive shaft and motor which work together to circulate air through the tower. The mechanical assembly is designed for efficient airflow,low vibration and reliable operation.

Cooling Tower Film Fills

Film fills are PVC or polypropylene sheets arranged to maximize contact between air and water, enhancing heat transfer efficiency. They increase the surface area for water to spread into thin films, promoting rapid cooling.

FRP Fan Stack

The FRP fan stack is a cylindrical structure that encloses the fan and directs airflow vertically. Engineered with robust, non-corrosive fiberglass to provide consistent operation and aerodynamic precision.

Water Distribution System

With FRP pipes, headers, and nozzles, the system distributes hot water evenly over the fill, enhancing thermal efficiency and preventing uneven coverage.

Drift Eliminators

Constructed from FRP or PVC, drift eliminators capture airborne water droplets to minimize evaporation losses. These components reduce water loss through drift and support efficient water usage.
