Water-water-chiller (System separator)Photo shows water-water cooler with 30, 50 and 70 kW powerDimensions 30 kW: W x D x H = 590 x 620 x 1205 mm50 kW: W x D x H = 680 x 730 x 1520 mm70 kW: W x D x H = 800 x 850 x 1665 mmToday, many institutes already havetheir own cooling water supply. Thiscooling water is generally too cold tocool a laser or an electronical microscopeor the water quality may be ofa poor quality. As a system separator,the KÜHLMOBIL offers the idealsolution for such problems and hasvery small dimensions. It operateswithout a compressor and consequentlywithout any refrigerant –only the feed pump requires energy,as the refrigerant output uses thedomestic water system. The drawingon the next page showsthe basic functional principle. Thepurchasing price of such a deviceis far below those of a compressorcooleddevice.This appliance works with a 3- waymotor valve. Due to the analoguesteering signals (0-10 V) the constanttemperatures will be reachedand source of disturbances will bebalanced.The variant is also available with amotorised valve, controlled via amicroprocessor-controlled PID regulator.Further details are provided onpage 26.25
