Clair\u2019s Aid for capacity enhancement<\/strong><\/p>

Introduction:<\/strong><\/p>

We received an order from a leading cement client from Kurnool, Andhra Pradesh. It was for a Gas cooling system for capacity enhancement equipment for pollution control at their Kurnool Works site. We successfully installed a FD Cooler where the application was for a 16 MVA Furnace fumes collection with a gas inlet volume of 3,55,000Cu.mtr\/Hr.<\/p>
