The new generation of manifold heat exchangers, soon to be launched by Thermex

The METS trade fair in Amsterdam later this month will see Thermex launch their exciting and innovative new generation of Marine Manifold Heat Exchangers with up to a 20% increase in performance over the existing design.

Thermex have been manufacturing marine and industrial heat exchangers since their foundation in 1979. One of the most successful products is the manifold heat exchanger that can cool exhaust gas and engine jacket water in a single unit. 5 years ago, a change in operations for the main customer of this product led to a reduction in sales which left Thermex with a dilemma, to discontinue the range or redevelop?

Thermex chose to redevelop and fortunately, the decision to improve the product has already yielded great results with the first orders now in production and prototypes in test with several firms in Europe, America, Canada and Turkey. They are being used on propulsion and gen-set engines with 2, 3 and 4 cylinder configurations.

The success is due more to simplifying rather than innovating. Many of the components used on the old design were unique to it, but these have now been replaced with standard components that are easier to machine and build. They also enabled Thermex to redesign the internal tube stack to provide a significant boost in performance, calculated at 20% in some models. The housing is also produced from an extrusion, which means that it can be easily adapted to fit a wide range of engines without the need for more tooling.

Currently they are mainly supplied to marinisers of Kubota engines but can also be used on some models of Isuzu, Daedong and similar variants up to 6 cylinders.
