ITEX Gasketed plate heat exchanger h eatingselection Due to the range's extreme modularity, the selection has been optimised based on the thermal requirements and the allowable pressure drops for the fluids utilised. The importance of this factor must not be underestimated when selecting a heat exchanger, as it influences the choice and number of plates and thus the transfer area. The transfer area is also influenced by other factors, such as the height to width ratio, the gap between the plates, and the angle and depth of the chevron patterns. a Dvantages pRecaUtions ■ Excellent transfer coefficient, giving a reduced surface area.Do not damage the exchanger gaskets (one per plate): ■ Very low pinch point temperatures possible. ■Prevent overheating, water hammer and overpressure, and ■ High corrosion durability. limits on-off cycles. ■ Compact footprint. ■ Do not use 1/4-turn valves. ■ Easy to install and maintain. ■ Use with steam between 0 and 3 bar (eff). ■ Low-capacity circuits and fluid retention volume. ■Provide a control system adapted to the requirements and ■ Option of surface area extension. which takes the low capacity of the circuits into account.. ■Unit can be cleaned in-place using a circulation system Keep the plates clean toguarantee thermal efficiency: (NEP or CIP). ■ Filter fluids containing suspended particles. ■ Max. differential pressure = max. operating pressure. ■Ensure the fluids are constantly circulating in the exchanger to prevent any build-up or scale. ■ I nstall nozzles on the pipes for cleaning in place.
