Cooling Towers Plants

Square shape cooling Towers

Square shape cooling Towers

Square Shaped Towers cool the re-cycled water. The towers blend easily with architectural surroundings, giving a unique aesthetic appearance.

Designed to cool industrial re-cycled process water from temperature of 50 degrees to temperature of 4 plus the prevailing Wet Bulb temperature of the region. The design incorporate the static spray nozzle distribution to atomize water in to a mist state and ensure uniformity in water dispersion and are easy to maintain even during the tower operations.

The hot water from the application is dispersed uniformly over the wet deck fill by means of static spray non clog nozzles. Simultaneously, air is induced through the fill media thus taking away the latent heat from the water passing through the fill media. Portion of water evaporated, removes the heat from the remaining water. The warm moist air is drawn through the fan deck is discharged to the atmosphere. Cold water, collected at the collection sump, is re-circulated to the heat source.

Principal Function

The tower designs incorporates a static distribution setup, located above the fill media. Hot water form the application is circulated to the distribution header from which they are dispersed over the fill media by no. of non-clog static nozzles, fitted to the branch pipe of the main header. Water when forced ( 1 to 1.5 kg/scm) through the distribution setups is atomized and sprayed over the fill media. The fan that is coupled directly to the motor draws air across the fill media vertically and in the process takes away the heat from the water. Cold water is collected at the collection sump having the outlet connection through which cold water is circulated to the application. The spray losses are minimized by using adequate drift eliminators. The distinguishing features of our product are compact design Honey comb type PVC fills, with varying flute sizes, to provide maximum contact surface area and heat transfer surface per unit volume.

Round Shape Cooling Tower

Round shape cooling tower

Round shaped or popularly known as bottle type are designed to cool industrial re-cycled process water from temperature of 50 degrees to temperature of 4 plus the prevailing Wet Bulb temperature of the region.

The tower design incorporates hot water inlet at the bottom collection sump circulated vertically to the mechanical rotary sprinkler located above the fill media. The inlet water pressure rotate the sprinkler, having extended arm pipes with orifices to disperse water uniformly over the fill media.

The fan directly coupled to the motor, during operations takes away the heat by induced draft mechanism. Air is drawn from the lower air in take area & is induced to travel through the fill media thus taking away the latent heat from the water passing through the fill media.

Cross Flow Cooling Towers

 

Cross Flow Cooling Tower

Technical Function
The tower design incorporates a FRP distribution basin with number of flower type target nozzles in it and is located at the tower top. The water, by gravity, is dispersed over the fill media uniformly and water is allowed to pass vertically down along the honey comb fills.

  Evaporation Cooling Towers

  • The evaporate cooling towers essentially combines a cooling tower and a condenser coil in single equipment. It eliminates the sensible heat transfer step of the condenser coil water which is required in the cooling tower/condenser system. This permits a condensing temperature substantially closer to design wet-bulb temperature, and consequently, minimum heat process energy input.
  • The closed circuit cooling tower was being tested at our factory with real heat load, with required water flow and was exported to Iraq after confirming the performance.
  • The fan system sucks air through the falling water and over the coil surface. A small quantity of the water is evaporated, removing heat from the primary circuit and cooling it inside the coil. Therefore, like the cooling tower, all of the heat rejection is by evaporation, thus saving about 95% of the water normally required by a “once-through” system.

Modular Cooling Towers

Modular Cooling Towers

Amodular cooling tower assembly is provided that comprises at least one cooling tower module having extendible legs capable of supporting the assembly when fully extended. When more than one cooling tower module is used in the assembly, adjacent modules are attached together at their respective frames. A single exit plenum chamber is placed over the joined modules and a single fan in the exit plenum chamber causes an air intake from an air entrance plenum chamber at the bottom of the modules upwardly past the fill sheets and out the exit plenum chamber and fan cowl. The cooled liquid falls into a common collection basin in which the extended legs of the modules are standing.

Natural Cooling Tower

  • Devoid of either the fan or the fill media these towers are guaranteed for 100% savings in power & maintenance down time. The special aero dynamic designed FRP / GI louvers minimize spillage and evaporation losses.
  • The Hot Dipped Galvanized structural and S.S. fasteners increase the life periods of the towers.
  • Their unique non clog nozzle atomizes water to fine mist state to ensue efficiencies of the towers and are easily maintained even during operations
  • In this process, water gets cooled and the air gets heated / saturated thereby caring away some sensible heat from water.

These Cooling Tower are designed on the principle of evaporative cooling in which, hot water comes directly in to contact with the ambient air and the cooling is achieved mainly by portion of water that is atomized to a mist state, which is then converted to vapors, thus caring away the latent heat of evaporation. In this process, water gets cooled and the air gets heated / saturated thereby caring away some sensible heat from water.

TECHNICAL FUNCTION

The name “FAN LESS FILL LESS” says it all. Devoid of either the fan or the fill media these towers are guaranteed for 100% savings in power & maintenance down time.

The special aero dynamic designed FRP / GI louvers minimize spillage and evaporation losses. The Hot Dipped Galvanized structural and S.S. fasteners increase the life periods of the towers. Their unique non clog nozzle atomizes water to fine mist state to ensue efficiencies of the towers and are easily maintained even during operations The Hot water from the heat source is circulated to the inlet header of the Cooling Tower. The inlet header pipes have branches and sub branches covering the internal area of the cooling towers. The non clog nozzles are connected at the outlets of the sub branch piping’s.

At an inlet pressure of 1.5 to 2 Kg/cm2 to the Cooling Tower, the hot waters are atomized to a mist state. The nozzles are self designed to create more pressure thereby converting water into minute atomized particles. From the four sides of the louvers, plenty of fresh air is automatically circulated by the aero dynamic designed FRP louvers. Waters are directed by the special aero dynamic louvers towards the collection sump. The louvers ensure that the water do not spill out of the towers.

The hot waters, that are in a mist state, comes directly in to contact with the ambient air and the cooling is achieved mainly by, the portion of water, that gets converted to vapors, thus caring away the latent heat of evaporation. Therefore, water gets cooled and in this process, the air gets heated, saturated and thereby caring away some sensible heat from water.
