Global Specialists

Chart subsidiary IMB specializes in the design and manufacture of specialty shell and tube heat exchangers with over 5,000 units operating in the oil, refining, chemical and petrochemical sectors.

High Pressures & Specialist Metallurgy

Specializing in heat exchangers up to 200 tonnes for applications that require high pressure operation or severe service with exotic metallurgy.

Materials of Construction

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.


HELIXCHANGER® heat exchangers facilitate 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.


Basic building block for a broad range of plastics and one of the most important monomers produced by the petrochemical sector. IMB specialty heat exchangers cover multiple services on licenced plants achieving high styrene selectivity where ethylbenzene is dehydrogenated to styrene over potassium promoted iron oxide. A typical plant incorporates 2 or 3 reactors in series.

IMB is referenced for many processes, including SSW, Badger and Snamprogetti and boasts an extensive reference list, including reactor reheaters and 3 car garages.


IMB is an approved vendor for a number of licensors producing ammonia via their own proprietary technologies, including Haldor Topsoe, KBR, Ammonia Casale.

Introducing SPINTUBE™

Retrofitting a tube bundle with SPINTUBE™ is the most cost effective way of improving performance.
