Block vs Shell & Tube

Heat Exchanger Repair, Rebuild, Refurbish

So why do customers still request cylindrical block heat exchangers?

In the early years of graphite heat exchangers, cylindrical block was a common design. Isostatic molded graphite block material was readily available. As extrusion methods advanced and fully graphitized tubes became available, the shell and tube design became the more viable option. Why?

The total lifetime cost of ownership of a graphite shell and tube heat exchanger is less than a graphite cylindrical block heat exchanger.

So why do customers still request cylindrical block heat exchangers?              

Because that’s what they know and because there are instances in which a low fixed shell side flow-rate, large temperature range, or length restriction might make the block unit more competitive.
