. kyHygienic Double Wall Plates Increase Production Safety FrontLine™ - Gemini Plate Heat Exchangers Gemini plate . Application Pasteurization and general cooling/heating of dairy, brewery, beverage and food products, when a mixproof design is required. Also applicable for cooling/heating in the pharmaceutical industry. Working principle A plate heat exchanger consists of a pack of corrugated metal plates with port holes for the passage of two fluids between which heat transfer will take place. The plate pack is assembled between a fixed frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the inter-plate channel and directs the fluids into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids and the temperature program. Connections may be located in frame plate and pressure plate and if multi section PHE, also in connection plate Frame The plates and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to the support column. The tightening bolts are equipped with ball bearing washers in order to facilitate opening and closing of the unit. The frame and support column have adjustable feet. One unit may contain several heat exchangers, separated by connection plates with interchangeable connections. The Gemini plate The Gemini plates consist of two sheets formed together in order to minimize the inter-sheet air gap reducing the heat transfer. The gap between the two sheets is in direct contact with the atmosphere and is not in contact with any of the liquids. In order not to trap any liquid between the two sheets, contact to the atmosphere is safeguarded around the whole periphery of the plate. The Gemini double wall plates will increase the production safety, as a crack in a plate do not result in mixing of the two media.
