Annular Space Heat Exchanger Solutions for Industrial Service
Krueger Engineering manufactures custom heat exchangers and supports annular space heat exchanger solutions that enable controlled heating or cooling by directing product flow through an annular passage for consistent thermal performance.

Custom Annular Space Heat Exchanger Designs for Industrial Systems
A key feature of annular space heat exchangers is their concentric flow arrangement. In this design, the process fluid flows through the annular space between two pipes, while the service fluid flows through the inner passage or surrounding section, depending on the configuration.
Krueger Engineering assists in the design of custom-made exchangers based on the available shell-and-tube technologies and heat transfer simulation by HTRI software and mechanical calculations with PV-Elite, Compress, and Nozzle Pro software tools. With in-house CNC machines and the ability to fabricate the equipment according to the ASME Section VIII code, we can deliver heat exchangers designed to operate in harsh industrial conditions.
