PULTRUDED FRP INDUCED DRAFT COUNTERFLOW COOLING TOWERS

CF3 12-Dec-2017

PAHARPUR SERIES CF3 FIBREGLASS COUNTERFLOW COOLING TOWER Paharpur's series CF3 induced draft cooling tower represents the culmination of more than 50 years of counter flow design experience. With polyvinyl chloride fill and glass reinforced polyester structural, basin and casing, the series CF3 continues a tradition of excellence.

Improvements and innovations in structure and component designs produce in the series CF3 a heavy-duty, energy efficient and dependable cooling tower unrivaled in the industry. Perhaps most importantly, all major components responsible for this breakthrough have been developed, manufactured, applied and guaranteed by one single source company – Paharpur. Without question, the series CF3 establishes a new state of the art in counter flow cooling tower design.

PAHARPUR'S INTEGRATED SYSTEMS DESIGN Although Paharpur's original motivation in the design and manufacture of all major cooling tower components was to assure dependability and longevity, a secondary benefit quickly became of prime importance. That benefit was the ability to coordinate a variety of components of known design characteristics into a cooling tower of assured thermal performance predictability.

Paharpur's philosophy of component design has been – and continues to be – to assess the value of a development only in terms of its effect upon the total cooling tower system. Particular fills, fans, fan cylinders, etc., tend to optimize within a very narrow range of tower configurations and design parameters. Consequently, a considerable variety of individual components is required in order to achieve a near-ideal combination for any operating circumstance. And it is imperative that these components be designed and rated within a cooling tower system context.

Paharpur has all such variety of components. Their capabilities are well known because they were designed and manufactured by Paharpur.

FILL: Vacuum formed polyvinyl chloride (PVC) sheets are solvent welded into a cross corrugated configuration to provide maximum heat transfer surface with minimum pressure drop and pump head.

ELIMINATOR: Drift eliminator panels are formed from PVC sheets into a cellular configuration which forces exhaust air into three complete directional changes to eliminate water droplets from the air stream. The 3-pass eliminator provides maximum efficiency in elimination at the very minimum in horse power consumption.

SPEED REDUCER: Designed and manufactured to furnish extended service life in industrial water cooling applications, Paharpur gear reducers have an overall mechanical efficiency of 95%. Their rugged design has been proven by years of field operational experience worldwide.

FAN: Designed, tested and manufactured by Paharpur. Fan materials include cast aluminium alloy, glass reinforced polyester, and glass reinforced epoxy. Fan sizes and

materials are selected to provide the most efficient solution to any cooling tower application requirement.

DRIVE SHAFT: Utilizing floating tubular shafts and neoprene flexible elements. Paharpur designed and manufactured drive shafts do not require lubrication and are dynamically balanced prior to shipment.

DISTRIBUTION SYSTEM: Uniform hot water distribution is guaranteed by Paharpur's injection molded polypropylene nozzle, incorporating a unique diffusion ring for spray development distribution. This nozzle system is specially designed to function under low operating heads for greater energy efficiency. Large diameter orifices contribute to overall reduced maintenance costs.

FAN CYLINDER: Fan cylinders are Paharpur designed and manufactured glass reinforced polyester (GRP), molded to provide a large entrance flair, smooth approach to the fan, and close tip clearances for maximum efficiency and reduced operating costs.

STRUCTURE: Structural components are glass fiber pultruded composite. Columns are 65 X 65 nominal box section with a minimum 5 mm wall thickness and carry loads to anchor castings. Columns are spaced on no greater than 1520 mm centers both longitudinally and transversely. Diagonal and other structural connectors are through bolted.
