This tower design has been developed after detailed research and analysis of the engineering design. The design allows a substantial saving in space, power and water consumption.
Our State-of-Art technology is best suited to the industrial requirements as per Indian environmental condition..
A Cooling Tower is a direct contact heat exchanger, generally used to dissipate the heat in circulating water. The heat is dissipated to the ambient air via a process of heat and mass transfer from the circulating water. The water thus cooled is circulated again through the process, heat exchanger or condenser. The heat is transferred to the water either in a condenser like refrigeration or air-conditioning system or chemical processes or heat exchangers in cooling process, generating sets, engines, furnaces etc.
The cooling tower design has changed over the years to incorporate new materials, as and when available.
- Perform to required specification.
- More compact
- Weigh less
- Consume least power
- More long lasting, withstand corrosion and have good finish looks.
Principle of Operation
The automatic rotating sprinkler system distributes the hot water evenly over the entire fill section. Dry air is simultaneously drafted upward causing evaporation. The cooled water falls into the basin and is pumped to the heat source for recirculation.
Better Air Flow
The rotating water sprinkler head distributes the hot water within forming a fine spray, and hence does not need the conventional type of moisture eliminator. This is because the water header has large number of holes giving a ‘steam’ type flow directly into the infill. Towers with fixed nozzles cannot obtain the coverage, which is needed for optimum cooling. We should not overlook that in rectangular type towers, eliminators provide a pressure drop which evens out the flow particularity into the corner.
The ‘Advance’ tower being round, plus its conical fan inlet can better provide an even air flow through the infill, with a lower pressure drop, and without the additional pressure drop caused by the eliminator needed on other towers.
Fan KW depends on the mass of air delivered, the pressure generated and the blade efficiency. “Advance” air volumes are similar to competitor’s sizes. The influencing factor for lower power is ‘pressure’ and ‘efficiency’.
- The “Advance” tower has large air inlet area, with low air velocity, low pressure drop.
- The “Advance” tower is of the induced draft type.
The fan is in the ideal position, to discharge the air at a high velocity upward and allow natural convection to prevent recirculation, as can happen with the forced draft tower arrangement, where air leaves the eliminators at low velocity.
The water distribution by a rotating header, is a significant part of the “Advance” tower design. The large diameter holes in the rotating header give a gentle stream of water at negligible pressure loss. Also, there is no risk of ‘clogging’, as can easily happen with spray nozzles in other types of towers.
It should be noted that pumping heads quoted for “Advance” towers include both of these as well as the piping inside the pressure loss of the sprays. To this must be added the static lift to the spray header from the basic water level, plus the external piping friction loss. In many cases the pumping head required for an “Advance” tower is about 50% less than for some other towers.
Although we generally refer to the towers as being constructed of fiberglass, we should actually refer to them as being FRP (Fiberglass Reinforced Plastic)
FRP should not be confused with the translucent fiberglass roofing panels, and in particular with the cheaper grades which have given poor results even only in a few years. Without an adequate protective layer, the sun’s ultra violet rays draw the fibers upward so that ‘hairs’ appear to be growing on the panels as with fiberglass hulls, the “Advance” tower casings have a protective Neopently Glycol gel coat, which apart from containing the pigment colour, entirely resists the sun’s rays. As a result, “Advance” towers do not need painting. However, if a client wishes to have a colour scheme changed, painting is possible.
Compared with timber towers which will ultimately rot, or steel towers which will rust despite increased maintenance, the fiberglass tower has a tremendous financial advantage for the wise investor. Unfortunately, many buyers appear to be only concerned to maintenance, running costs or rate of deterioration.
Excellent FRP Quality
Superior quality of FRP laminates with isothelic resin increases the strength of the casing which reduces the vibrations and it gives assurance of longer tower life.
