The Sigma Water Chiller is a device for chilling water continuously in order to guarantee high quality products throughout all seasons of the year. The combination of the direct proof and ice accumulation (patent) allows a fast ultra lowering of water while preserving a very significant flow. This system of continuous cooling guarantees perfect sanitation. Thanks to the use of the natural pressure of the water supply network, the Sigma Water Chiller works without an additional pump. The use of an oversized refrigeration unit and 2 thermostatic regulators ensure optimal functionality.
