The broadest range of cooling towers designed specifically for rigorous duty encountered in producing electricity, fertilisers and those products related to petroleum refining, petrochemicals, process chemicals and general manufacturing is available. A continuous research and development programme matches customer requirements with the best materials and techniques including environmental compatibility, closer evaluation of energy cost and changing availability of basic material
CLASS 400 WOOD AND 800 CONCRETE
In keeping with the Paharpur tradition, the Class 400 Wood cooling tower advances the state-of-the-art in its category. Designed for dependability, durability and operational simplicity, the Class 400 tower evolves from an impressive ancestry of counterflow towers. The Class 800 concrete rectangular mechanical draught tower retains all the advantages of the Class 400 and adds to them the durability and non-combustibility of concrete. Available in in-line and back-to-back configurations with PVC film fill and the famous Paharpur mechanical equipment. Standard drift eliminators are also PVC. PVC film fill results in remarkably low pumping heads.
CLASS 500 WOOD
A versatile cooling tower available in a wide selection of frame sizes to efficiently serve application requirements in large process cooling and air conditioning projects as well as in intermediate size power stations. Features include Paharpur built components-designed and manufactured fro cooling towers; pressure treated wood structure-providing high strength and proven longevity; cross-flow design-providing the most efficient fill configuration, allowing water/air contact with more cooling per square foot; FRP fan cylinders-specially designed for higher efficiency; gear reducers and fans designed and manufactured for efficient long life under hot, moist corrosive atmospheric conditions.
CLASS 600 WOOD
This cross-flow tower incorporates just about every design advantage that has been conceived during the years, providing thermal performance, low drift for today's environment, and minimal long term maintenance cost. Both single and double air entry configurations offer mechanical, structural and operational advantages which result in greater efficiency, lower maintenance and longer service life. Available with PVC or treated wood splash fill, in virtually unlimited capacity.
CLASS 1000 CONCRETE
Class 1000 concrete structure mechanical draught tower in a low profile configuration. The primary design features are: non-combustibility and a unique design that offers compact siting, reduced piping and water supply economy. Precast and prestressed structural components reduce construction time. Paharpur-made mechanical equipment. Choice of treated wood, concrete and plastic fills for longevity and durability.
CLASS 800 NATURAL DRAUGHT (HYPERBOLIC)
These towers are suitable for the largest heat load applications. Hyperbolic natural draught towers may be specified : (i) where the geography dictates maximum height release of moist air plumes; (ii) for confined restricted area sites; (iii) where extremely high power cost make natural draught most applicable. Attendant advantages of hyperbolic towers are simplicity of operation as no mechanical equipment is used and total avoidance of heated air recirculation, as plume dispersion is at considerable height. Available in counterflow and crossflow design. Fill options are prestressed concrete and PVC/PP (splash type) and PVC (film type). Supported by technical know-how from Knight Piesold.
