[Background]GEA PolacelGEA Polacel is a company of the GEA Group AG. The GEAGroup, headquartered in Bochum, Germany, is a globally successful technology group with more than 250 companies in50 countries.One contact person for all solutionsThe company now focuses on specialty mechanical engineeringGlobally active in more than 40 countries– especially process engineering and equipment. GEA Group tech-Native speakers speak your languagenologies are applied in the food, chemical and petrochemical in-Individual solutionsdustries, the energy sector, air treatment and shipbuilding as wellMaximum availability, security of operationas the pharmaceutical and cosmetic industries. The GEA Group isand system efficiencyone of the world s market and technology leaders in 90 per centof its businesses.GEA is a solid foundation for the GEA Polacel activities and it provides us with greater scope. Good contacts with affiliated organizations that are leaders in our field provide an ongoing stimulus toour own development. This is what makes GEA Polacel a leader inthe introduction of technological improvements.

[System‘s functions]The effect of counterflowCMDR cooling towers work on the principle of counterflow.This means that the water flows down while the air is pulledupwards by a fan.As the water flows further through the system, the air it encounters is fresher, in other words cooler and less saturated with moisture. Counterflow cooling towers can approach the wet bulb temperature better compared to crossflow cooling towers.[Know how]Polacel CMDR cooling towersPolacel designs, manufactures and maintains cooling towersfor process and climate cooling. Our energy-efficient andenvironmentally-friendly cooling water generators stand outbecause of the complete quality policy we employ.The Polacel CMDR systems combine a high cooling capacity withlow energy consumption. The modules are supplied ready to useand they are easy to adjust to cooling requirements and the available space, whether they are used singly or in series. The coolingperformance of these cooling towers is optimal and operation isproblem free. With a 95% saving in water, the efficient CMDRsystems are the best choice for man and his environment.3GEA Polacel Cooling Towers

[Maximum efficiency]Cooling performance measured:the wet bulbThe wet bulb temperature is in fact the lowest temperaturethat can be achieved by air cooling in any particular set ofcircumstances.CMDR cooling tower type 460Car manufacturer in GermanyThis temperature can be measured by wrapping a glass thermometer in a piece of cotton that has been drenched in water andplacing it in a stream of air. The water will evaporate and loseheat (sweating while taking exercise has the same function andmakes a ‘cooling tower’ out of our skin). The wet bulb temperatureis there fore lower than the ambient temperature.Cooling towers try to approach this achievable minimum temperature using as little energy and as efficiently as possible. TheGEA Polacel CMDR range succeeds in doing this and combinesmaximum efficiency with low power consumption, and thereforeminimal costs.CMDR cooling tower type 380Chemical Plant in Germany[Modular system]Modules to sizeThe cooling water temperatures (inlet and outlet), the wetbulb temperature, noise and the water load are the four mostimportant factors in the selection of a cooling tower.GEA Polacel makes an inventory of the requirements together withthe client and uses this inventory as the basis of the design for asuitable solution. The modular CMDR system can be extended,and there are standard solutions available for different capacityneeds. GEA Polacel engineers make customized changes to meetspecial require ments.CMDR cooling tower type 630Chemical Plant in Germany
