In 2002 Mihir introduced a new design combining FRP with RCC Cooling Towers for capacity upto 3000 CMH per cell. With more 1000 towers installed this design has been a huge success in Process Industries and Captive Power Plants with capacity ranging from 2 M.W. to 20 M.W.
Design Advantage
*
Motor and Gearbox are directly coupled on a common mounting frame supported on a center RCC column thereby avoiding any vibrations commonly caused by misalignment of transmission shaft between motor and gearbox.
*
This unique concept of center RCC column allows FRP casing and FRP fan section to be kept independent of rotating parts like gearbox, motor and fan.
The onsite RCC construction cost of these towers is considerably low as the casing is in FRP which is manufactured at the factory and assembled at the site.
*
The operating costs of these towers are comparatively low as the power consumption is reduced by providing extra quantity of fills which increases the wetted surface area.
Salient features
*
Basin and Air entry portion are in RCC
*
Casing & Fan section are in FRP
*
Entire load of PVC fills rests on RCC structure, thereby avoiding load on FRP casing.
*
For contaminated water and water with suspended particles PVC fills of flute size 19mm can be used.
