Industrial Cooling Tower

Cooling Tower Principle of Operation

Cooling Towers come in many different shapes and sizes. They range from small 3 feet * 3 feet factory assembled models to large field erected cooling towers capable to rejecting thousands of BTU / Kcal of heat. Although the shapes and sizes can vary, the principle of operation remains the same.

Warm water from the heat source is pumped to the water distribution system at the top of the tower. The water is distributed over the wet deck fill by means of nozzles. Simultaneously, air is drawn through air inlet louvers and through the wet deck surface causing a small portion of the water to evaporate. The evaporative process removes heat from the water. The warm moist air is drawn out of the top of the tower by the fan and discharged to the atmosphere. The resulting cold water is then recirculated back through the heat source in a continuous cycle.

Wide Range of Capacity in Industrial CT

Available in 20 different models from one cell to twenty cells, both in Counter Flow & Cross Flow. “Nirvana” has a model for every application and capacity. If there is a special application, “Nirvana” will design a cooling tower that will fit your requirement. Contact with “Nirvana” head office or your local representative for alternate cooling tower solution.



Depending on application, size and client’s requirements, cooling tower structure shall be of the following type:

(a) As a standard, “Nirvana” cooling tower structure shall be MS Hot Deep Galvanized and suitably design to withstand wind load, seismic load and extended life. For corrosive atmospheric condition, Zinc based epoxy cote provided to improve life further. As an option SS-304 or SS-316 or SS-316L structure could be supplied.

(b) Chemically treated pine wood, conforming to IS-2372 and suitable for cooling tower application.

(c) Concrete (RCC) for longer life, steady and vibration free structure.

(d) Pultruded FRP with a flame spread of 25 or less, columns and diagonal braces are 3”x3” box section and for noncorrosive & lighter structure.

'Nirvana' cooling tower structural hardware can be supplied up to stainless steel DUPLEX grade, which is suitable for sea water application.

Casing & Fan Deck

The endwalls and sidewalls of the tower from air inlet elevation to the top of perimeter fan deck shall be cased with corrugated non-corrosive FRP panels attached to tower columns. Panels shall be lapped tool shed water inward to the tower. Corner rolls shall be provided to cover casing ends. Fan deck shall be of FRP.
