9 Email: rajguru.nct@gmail.com or Phone : +91 9833094837rajguru.nct@gmail.com 9 A) National Induced Draft Counter Flow Cooling Tower:- A) Other Cross Flow Cooling Tower In the Induced Draft Counter Flow, always the dry air is in contact with the cool water emerging out from the PVC fills. That means when the air passes through the PVC fills the proper water to air contact occurs and the water evaporate. Thus it loses it heat energy and the moist air is thrown out which will not be re-circulating because the total height of the cooling tower is maintained for the fresh air to flow from the bottom. It is a known fact that the cross flow cooling towers have the air entry from sides throughout & the distribution pans kept above the heat transfer area from the pan the hot water flow through the holes provided. The first layer of hot water which is falling down get in contact with the fresh dry air. It then extracts heat from the hot water and becomes moist and allows hot water to evaporate. Then hot water loses its heat and is collected in the basin. The second layer of hot water which is also flowing from the pan comes in contact with the same air which is moist and is with higher temperature. The rate of evaporation decreases and the water is not collected to the design outlet temperature because the approach decreases inside the cooling tower which effects the other layers of water & as the air passes inside the efficiency decreases & when the cold water is collected from the basin the temperature of water shall be the mean temperature of all the layers. Induced Draft Counter Flow Cooling Tower:-The moist air thrown out through the fan stack takes a chance in re- circulating through the air entry sides because of high velocity and the low fan stack height. So always cross flow cooling towers does towers does require higher installed power then counter flow cooling tower. NATIONAL Cooling Tower required 1Ft. to 3Ft. clear space on each side. This results in considerable space saving. Cross flow cooling tower have air inlet through louvers on sides and the air discharge is on the top. For proper performance of the tower above 6Ft. to 7Ft. clear space is required in front of the fan. For air inlet Why Counter Flow is always better than Cross Flow. Page 1 based on Practical ( Important points to be consider before buying)

10 10 There are no louvers in NATIONAL Cooling Towers. Cross flow cooling tower have louvers. This increase maintenance of the towers and the static pressure drop. Also the louvers are prone to breakage and therefore have to be replaced. NATIONAL do not have water distribution exposed to the atmosphere. Cross flow cooling towers have water distribution on top & header type which is exposed to sun. Due to this, chances of algae formation are increased. Also because of the exposed water distribution, dust tends to settle on the top and is circulated with cooling water. The dust and algae tend to depositing in air condenser chiller and compressor jackets, affecting heat transfer whereby discharge pressure will be more effects the performance of the air-conditioning plants. NATIONAL Cooling Towers have Two inspection cum service windows. Through these windows the water spray and the PVC Fills packs can be observed and corrective action if required can be taken immediately. Through these windows packs can be removed easily for cleaning without disturbing the casing of the tower. The removal of packs in cross flow cooling tower is very cumbersome & time consuming. NATIONAL FRP Cooling Tower is very compact and very light weight. Space requirement for cross flow cooling tower compare to NATIONAL FRP Cooling Tower is more For National Cooling Towers Service & Maintenance is considerably reduced because fan is the only moving part in the cooling tower. The fills eliminator can easily be approached from the inspection window without disturbing the cooling tower casing. NATIONAL Cooling Towers have totally FRP casing. FRP materials are corrosive proof and does not warp and deteriorate and very compact, height, weight and user friendly by increasing the total efficiency of the systems by ensuring the air flow from all the four sides from the bottom portion and bringing proper contact between water film and air stream. Why Counter Flow is always better than Cross Flow. Page 2 based on Practical ( Important) Email: rajguru.nct@gmail.com or Phone : +91 9833094837rajguru.nct@gmail.com

Can not guarantee dissipation of latent heat load. The dissipation depend upon wet and dry bulb temperature. 2Desired temperature dropped guaranteed.The temperature dropped is not constant and temperature dropped can not be achieved. 3Evaporation and drift losses are maximum 0.80% to 1.00% on your circulation of flow rate. Evaporation and drift losses percentage average around 2.00% to 2.50% on circulation of water flow rate or even more depending upon atmospheric seasonal wet and dry bulb temperature and due to wind velocity and height of Cooling Tower. 4Less area required and limited height.Required more area and higher height. 5Due to limited height the pump head is also required less in capacity. Height is more. The pump head is also required in higher capacity. 6Energy saving due to limited height, single header with 1/2” dia Spray Nozzles minimum quantity of Nozzles required. Energy required more to keep constant pressure for multiple water distribution header and multiple No. of Nozzles required to spray the water to achieve breakage of water. 7Foreign particles accumulated is negligible due to enclose body of Cooling Tower. Maximum open area. The accumulation of foreign particles is higher percentage, due to this Air-contaminated foreign particles the efficiency of Cooling Tower decreases day by day and chance of getting clogged of your process system incase any solid structural particles come into contact of inside of Cooling Tower. 8Cooling Tower efficiency guaranteed throughout working performance due to mechanical draught system. No guarantee of performance due to Natural Draught climatic condition.

Square shaped the uniform thickness are maintained. We provide Pyramid type dome. No. of segments are 10 to 12 and above casing. These segments are bottled shaped and neck type dome there are always possibilities of uneven thickness of casing. Fix header water distribution system has uniform water distribution without loosing the pressure dropped due to fixed header system. No tension bar and no Ball Bearing are required. The round shaped Cooling Tower consists of Rotary Sprinkler assembly with Ball Bearing System and Metal Tension Bar. The Cooling Tower water always contaminated with CaCo3. Due to contaminated water the bearings are likely to get jammed, corroded, worn out faster and over a period of used the tension of spring also get loose and its likely the reduces the desired ROTATION. Fix header water distribution system with water inlet on the top and outlet in the basin is easy to maintain within limited time. The water distribution system is on the bottom. To maintain this system is very difficult and consuming maximum time for servicing due to Arm Pipe gravity pressure system. F Installation of the square shaped Cooling Tower is simple and easy. The Cooling Tower without FRP Basin can be rested on RCC basin. No chances of vibration, since the entire Cooling Tower rest on RCC basin, which maintain the uniform load distribution. Installation of Bottled shaped Cooling Tower are provided with V bar metal support and in turn the V bar metal support are rested on RCC Pillars, Leaving the entire Cooling Tower hanging above the RCC Surface floor with the result the chances of vibrations are more. To maintain Square Shaped Cooling Tower any of your workers can do the job due to the simple system. You need to call trained personnel of Cooling Tower Company only. Nozzles are provided with 2.5” Diameter the turbulence effect for water spray is absolute uniform over the Fills area. No possibilities of air pocket development. With Rotary system water is just dropping from PVC Arm pipes with thick layer of water without getting water sprayed over the fills area, the chances of air pocket developments are maximum. Due to rotation of sprinkler Arms is being obstacle for dissipation of heat load generated in the Cooling Tower area. Due to the pressure drop the load increases on the fan to dissipate the heat load generated in the Cooling Tower with the result motor get tripped off frequently. ABS 2.5” Dia Nozzles reduces frequency of clogging. Wide spray angle. Easy lock installation and Nozzles removal need no tools. Fills placement is uniform due to the square shaped of Cooling Towers.F Fills placement is not uniform due to round shaped. To place the fills on round shaped is uneven and to fill the gap the fills segments are cut and placed with the result its likely that air pockets develop and as a result Tower efficiency is reduced. Maintenance is easy due to easy access through window and can be carried out even when the Tower is in operation. Maintenance is difficult due to fixed system of all components. No window is provided. Maintenance job cannot be carried out while the Tower is in operation. To maintain Square shaped Cooling Tower any of your maintenance personnel can carry out the maintenance job. You need to call trained personnel from the supplier of Cooling Tower.
