Multiplex Icecore™ Chiller Systems are Engineered to Perform. Multiplex new Icecore™ Chillers deliver the same, great refrigeration for both carbonated water and syrup while reducing energy usage by up to 30%. All water used for cooling drinks is recycled with virtually no waste water for reduced water and sewage expense. Multiplex remote refrigeration units produce cold carbonated water and chill incoming water and syrup prior to delivery to the dispensing towers in high-volume systems. Beverages with consistently proper carbonation levels and chilled temperatures lead to improved taste.
