hello my name is Franklin Lee I am the global sales manager for Joelle ethic changer reducing the risk of unplanned downtime is a big problem for customers it's a big cost because it's a cost from an operation perspective but also from a maintenance expenses this is especially a challenge when it's high fluctuations a severe condition was in pressure or temperatures this can lead mechanical fatigue and equipment to fail this is why we have developed Joe shell with those challenge in mind generally speaking the plate and shell technology offers much better resistance against the thermal or pressure fatigue than shell and tube heat exchangers however the conventional plate in shell as a number of design drawbacks this is why we have developed a unique latent shell in Alfa Laval which is called geo shell heat exchanger to make sure you bring advanced feature to our customers we have actually developed the one feature which is called the power pack which improved the fatigue resistance especially within the plate pack and also we have been using a patented plate pattern which is called the roller coaster and those features actually working and improving the fatigue resistance and therefore maximizing the uptime for our customers so if you are looking for maximized equipment at time especially in extreme pressure or temperature your shell is the obvious choice this is the reason why we call it plate and shell made tougher [Music]
