The cooling-tower market is already growing, and the leading international climate specialists are all predicting higher average temperatures in future, a trend that should be even more to the advantage of that industry. To make its cooling towers, the Parto Abgardan Company chose composites. arto Abgardan is a pioneer in the air-conditioning and refrigeration industries and holds about 80% of the market, with more than 3,800 units installed. Starting out in 1994 with a single bottle-type model, the company is now the largest Iranian (and Middle Eastern) cooling-tower manufacturer and has successfully designed four different cooling-tower models – bottle type, square type, modular type (open circuit and square type) and closed circuit, which it manufactures in 50 different capacities from 8 to 2,800 refrigeration tons. This innovative company operates locally and globally from a central office in Tehran, with a sister factory in the USA, which operates under specific standards. P FRP is key to Parto Abgardan cooling towers “Construction” FEATURE A lightweight, corrosion-resistant material Parto Abgardan’s products are used in the following fields of application: air conditioning, industrial refrigeration, power plants, air compressors, moulding machinery for plastics, welding systems, food processing, chemical processing, and foundry processing, among others. Using FRP gives a choice of ten different colours. Parto Abgardan recently manufactured specially designed cooling towers for the National Iranian Lead & Zinc Company plant (the largest plant in Iran). The three towers are used to cool down lead and zinc sulphates, which are highly corrosive. Designed to work under extreme conditions, the towers are 12 m long, 5 m wide and 10 m high. The whole project took six months, including design, manufacturing, installation and startup. More information Cooling towers are reducing temperature by evacuating heat JEC Composites Magazine / No33 June 2007 from circulating water, and to cool down heat loads. To this end, an air flow moves against a water flow, causing evaporation. To avoid rusting, corrosion, decay and weathering problems, the body of the cooling towers are entirely made of FRP . The innovative MB Series, the company’s main product range, benefits from a “total quality” production concept and establishes a new standard for cooling towers. Technical, weight and corrosion-resistance requirements prompted Parto Abgardan to choose composite materials for several key components of the cooling towers: - The casing and cold-water basin are constructed from nonferrous, high-strength fibreglass reinforced polyester (FRP) with ultraviolet (UV) stabilizer and exterior gelcoat for long life and durability. The tower design allows quick removal of the individual casing sections for full access to all tower components for maintenance and service. All the standard accessories in the cold-water basin are made from non-ferrous materials such as PVC, FRP ABS stainless steel and brass. , - The inlet louvers are made of FRP. Their design minimizes inlet air resistance, prevents water splash-out during operation and high-wind conditions, prevents bacterial growth by keeping
