Hi every:
what is the difference between BEM and BEU shell and tube exchanger?
To me its a 4 pass 1 shell exchanger. how would it effect your heat transfer?
Thank you very much for your explanation

Process:

I have uploaded more than one Excel Workbook with a detailed copy of the official TEMA heat exchanger type definitions (in COLOR) on our Forums. These workbooks are free for your unloading. All you have to do is employ the SEARCH feature on our Forums to find it and download all the workbooks you find. Your answer is easily answered by these workbooks; that's the purpose of my creating them - without your having to purchase the TEMA Standards.

By the way, the TEMA descriptions - BEM & BEU - have absolutely nothing to do with the number of passes (either shell or tube side) or the number of shells used. Where do you obtain the idea that it does? Do you have a copy of the TEMA Standards? Why do you believe what you state?

Thank you very much for your reply. I don;t have any TEMA standard nor do i have allot of Knowledge about Shell and Tube exchangers. Our Manager asks us to use BEU type of exchanger in our slandered design.
so i thought it will be better for me to find out from CHE Forum, Since from here i can good opinion of best engineers like you.
I realty appreciate your reply.
I am going to start my search for the workbook you uploaded here.

I certainly hope you are NOT planning on "slandering" anyone - much less an engineering design.

What I believe your manager is intending for you to do is to apply one of the lowest-cost exchanger designs available: the BEU TEMA type which calls for a U-tube type of fixed tube bundle.

Sorry Art It was typo mistake i mean standard design.

Process:

I knew that. I was only tugging on your U-tube - so to speak.

It's Friday, and a great weekend awaits us. You have a nice one.

P.S.: I am working on responding to your Amine query and I will post a detailed workbook on it probably tonight or tomorrow.
