15-17: Innovative FRP-Carbon Pultruded Shaft for Axial Fan Blades Cooling Tower Water Blowdown Treatment

15-17: Innovative FRP-Carbon Pultruded Shaft for Axial Fan Blades Cooling Tower Water Blowdown TreatmentCofimco extensive research and laboratory tests pointed out in the development of an innovative shank to connect the blade airfoils to the hub of large axial fans used on Cooling Towers and Air Cooled Condensers: the new pultruded FRP shank reinforced with carbon rovings. The innovative shank material gives to the blade a suitable elasticity, midway between flexible and rigid links, resulting in a noticeable reduction of the vibration level introduced

A Pilot Cooling System was developed to simulate the operation of an open recirculating cooling system for the purpose of evaluating potential cooling water treatment programs on a pilot scale prior to their implementation in the refinery cooling system
