BOTTLING / FILLING 27 PET planet Insider Vol. 18 To complete the system, the excess heat generated will be rejected to ambient with a central Ecodry Adi- abatic Cooling System (instead of evaporative cooling tower), which pro- vides the MultiStage unit condensers with maintenance-free, close circuit water with almost no water or chemi- cal consumption. The Adiabatic Cooling System, which will provide a cooling capacity of 1,500kW (with two coolers with 20 fans each) is being installed outdoors in the utilities area. One simple set of non-insulated piping mains and drops will connect it to each water cooled Multi- Stage cooling unit installed indoors and close to each processing line. Coca-Cola Andina, after an extensive techni- cal and economic analysis, chose Frigel’s solution, as they perceived various advantages compared to a traditional “central” cooling system for their company. Flexible coolant temperature control These include that the “Process-Synchronised Cooling” gives flexibility of coolant temperature con- trol supplied to each line, assuring with high precision the ideal product carbona- tion temperature according to the actual type of product and bottle format. Cost savings of 30% Constant flow rate is delivered to each carbo- mixer, ensuring stability and avoiding flow interference from other lines, while the bottling line runs stead- ily at the highest speed. Also, thanks to the multi- cascade refrigeration unit performance (EER/COP) per line, the 100% natural gas savings obtained by heat recovery for opera- tion of the warmers and the 95% water savings for heat rejection, Coca Cola Andina has estimated an overall operating cost savings of 30% when compared to the traditional “central” cooling system option. This new plug & play concept is easily expandable at any time, which will allow Coca Cola Andina to install only the precise capacity needed at every stage of the plant growth. Also on the plus side: with 90% less glycol usage, almost no water footprint, no ammonia and a 40% carbon footprint reduction compared to traditional “central” cooling sys- tems, this new Coca Cola facility will achieve high standards for overall sustainability. www.beverage.frigel.com
