Paharpur Class 1000 is our most heavy-duty crossflow industrial cooling tower. It is part of Paharpur’s renowned fleet of industrial cooling towers; this RCC field-erected, induced-draft crossflow cooling solution represents the best of industrial process cooling.
The Class 1000 is an extremely versatile product which can be customised according to your particular requirements. It is especially well suited for heavy industrial applications in power plants, fertiliser plants, petrochemical complexes and petroleum refineries where water quality are not easy to control and reliable thermal performance is crucial.


When it comes to process cooling, there is no ‘one size fits all’ concept that works. Paharpur’s products are customised depending on a multitude of factors – geography, environment, type of industry, requirement, water quality, temperature fluctuations etc.
Our highly qualified engineers guide you through the process of selecting and designing a cooling tower best suited to your needs. The Class 1000 is a highly customisable Timber/FRP tower available in varying cell sizes that differ in 1.22m of length with customised fill type & density, fan type & size, number of blades, applied horsepower, fan cylinder height & shape, drift eliminator type & density, along with water distribution type and pump head.
By providing a unique situation best suited to your need Paharpur guarantees that all components work flawlessly and deliver high performance so that you get the most out of your process cooling solution.


One of the major advantages of crossflow cooling towers is that of online maintenance. Downtime is very expensive and Paharpur provides much scope for online maintenance – complete inspection of your cooling tower can be conducted during performance, in addition to replacement of fill, louvres and some support structures. A central plenum walkway above the basin provides easy access and a complete view of the fill area on both sides – such that damage, sagging and misalignment can be identified and promptly rectified.


Crossflow cooling towers are provided with Paharpur Splash fill. These are perforated V-bars made of pultruded FRP and exhibit a remarkable immunity to poor water quality. Very often it is not possible to maintain water quality – there is always some particulate matter or dissolved chemicals which may cause clogging and damage to fill.
Paharpur’s robust and resilient splash fill bars provide the necessary surface-area for effective thermal exchange while also providing minimum resistance to airflow. The result is a long-lasting fill which lasts for a long time.


To ensure that you get the most out of our products and for your peace of mind, we can perform regular inspections of your tower- this gives you the distinct advantage of predicting operational problems and secure high tower performance with zero downtime.


Paharpur’s experienced construction teams take complete control over the on-site erection of your tower with supervising engineers. Our team uses the latest technology to control shell geometry with a computerised laser surveying station; the concreting and material handling is managed by a centrally erected tower. Construction services also include finishing and testing your tower to help ensure that you get nothing but a high performing tower with a long service life.
