Coolflo Engineers PVt Ltd are a professional organization, which was founded by the most experienced men in the domain of cooling towers and fans in India. Our organization was established by three Ph. D degree holders in the year 1989, who hold proven experience in FRP technology, Fans and Cooling Towers. The continuous R & D work done and recognition achieved by our directors in India and abroad, is established by the list of research/technical papers that were presented at national and international conference on fans and cooling towers. Back in 1982, Our founder Directors were the only Indians to present a Research paper on “Design & Development of Large Axial Flow Fans for Cooling Towers” at the First International conference on Fan Design & Applications in Sept.1982, England, organized by BHRA, England. Prof. A. K. Rao, one of the Founder Directors was an eminent scientist in Aerospace Engineering, and pioneered development work at Indian Institute of Science(IISc), Bangalore. He was a consultant to M/S. Lockheed Aircraft Co., U.S.A. and was also a Scientist-Emeritus at the National Aerospace Laboratory, Bangalore. The scientists/professors from Indian Institute of science retained by COOLFLO also worked for many years in different laboratories and research centres of NASA, U.S.A. in the field of composite (FRP) structures and Aerodynamics. The engineering capability of these NASA trained scientists and the technological abilities of COOLFLO directors have evolved the proven hollow FRP blade fans in India.
