Cooling or heating issues for which GEA Bloksma does not have a standardized heat exchanger can be solved in a custom built shell & tube heat exchanger (at GEA Bloksma known as the N-type). The welded construction allows a flexible design. These special heat exchangers are produced by using as much standardized components as possible.

GEA Bloksma uses small diameter tubes (10 mm) in most special heat exchangers, which means that a large heat exchanging surface can be obtained at relatively small dimensions of the heat exchanger. Of course, larger tube sizes (like 16 mm) are also possible.

The N-type heat exchangers can be designed according to most design codes (for instance TEMA, ASME (incl. U-stamp), API, CE) and are accepted by all main marine classification societies. The tubes are roller expanded (cold-forming) into the tube sheets, which results in excellent connections, as for strength as well as for sealing. GEA Bloksma special shell and tube heat exchangers are built in three main types.
