- Fan Stack or Fan Cylinders are essential components in all Cooling Tower applications for protecting the Fan assembly and aiding optimal performance. It improves the velocity recovery by reducing the effect of dynamic pressure. It is responsible for the reduction of Noise and Vibration. It also serve the purpose of safety for maintenance personnel.
Fibreglass composite is considered as suitable material for Fan Stack as it offers structural reliability to withstand risky wind loads as well as sustain variable temperature and humid climate.
Resin Transfer Molding (RTM) is a closed mould process for manufacturing high performance composite components. It offers good overall surface finish which provides smoother airflow and makes possible to achieve relatively high fibre volume fractions for better strength.
CTI STD-124 covers the material of construction, workmanship, physical properties and methods of testing of FRP panels used in the construction of Cooling Tower fan stacks.
