High Pressures

Specializing in heat exchangers up to 200 tonnes for applications that require high pressure operation even in severe service.

Specialist Metallurgy

Routine fabrication in stainless steel (including super austenitic, duplex and super duplex), titanium, Inconel, Incoloy, Hastelloy, Zirconium, low alloy and low temperature steels, Monel and Cu-Ni alloys.


IMB's HELIXCHANGER® facilitates helical fluid flow on the shell-side providing performance advantages versus conventional baffled shell and tube units. References include large HELIFIN® and 'Texas Tower' heat exchangers.

Heat Exchangers for Offshore

Maximizing performance while minimizing space is the most critical aspect of every offshore installation. From large hairpin heat exchanger installations to sub-sea coolers, we offer the most comprehensive selection of custom designed tubular heat exchanger products and solutions. Furthermore, our technical consultancy, training and aftermarket service is second to none.
