hello my name is Martin Johnson and I'm responsible for the sales of Alfa Laval doership durashell is a plate and she'll heat to change her made tougher but it's not only a reliable product it's also a way to increase the heat transfer capacity in your plant for many businesses available space limits the heat transfer capacity and as such also the production capacity especially in hot summer days the door shell is five times smaller compared to traditional shell and tube heat exchanger so it means more capacity in smaller footprint the dura shell is compact also compared to traditional plate and shell heat exchangers it move the pass configuration with perfect distribution you take away external bulky piping meaning you have a more efficient e in less space and it's the only unit in the market that you can install both horizontal and vertical the possibility of using durashell goes beyond this due to its superior thermal efficiency it takes away a limitation in critical processes that are today limited by the heat transfer it also means you have closer temperature approach to the cold and hot side and that can give results like using in lower pressure steam instead of medium or high pressure steam that normally are costly which will improve your operating cost every business dream is to increase capacity without increasing cost if you are still using shell and tube heat exchanger or traditional plating shell today maybe it's time to ask yourself is it time for you to change you
