Delivering Quality, Cost-Effective Solutions - Fast!

About Us

We have been designing and manufacturing bespoke heat exchangers for over 25 years in our purpose built factory in Hartlepool, UK. Our prime focus is rapid turnaround of replacement exchangers using high quality materials as an alternative to the inflexible and expensive original units. We are able to cross reference original designs using our vast database of over 20,000 records and we hold tens of thousands of design drawings. In rare circumstances where we do not hold sufficient information, we will send our engineers to your location in order to obtain the necessary design data. This service is almost always free of charge. Our factory has excellent transport links by road, rail, air and sea and with our experience of exporting to almost any global destination, we can help remove the logistical problems associated with transport and customs.

We also design and build products for new applications which in the past these have ranged from “Deck de-icers” used to remove the build-up of ice from the deck of a ship to “Large Resin Heaters” used in a highly automated industrial closed loop process.

“We take pride in our personal tailor-made service.”


In 1997 we became part of DMI Global and we have benefited from significant investment. Our charge air cooler manufacturing plant is the most modern in the world enabling us to design and manufacture more than 500 separate designs per year. As a result of our growing success, in 2010 we were awarded the Queen’s Award for Enterprise.

How we Work

We hold the largest database of scavenge air coolers fitted to turbo charged diesel engines used within the marine and power generation industries. Because of this, we can usually identify the original coolers fitted to your engine from the smallest of detail such as vessel name, engine type and engine builder. Our thermal modelling software has been developed from actual real life data designed to closely match in-service conditions to ensure your thermal and exhaust emission requirements are met or exceeded. We are a professional company and we want to get it right. If there is any doubt regarding dimensions of the replacement unit, then it is quite normal for us to send one of our engineers almost anywhere in the world to survey the original unit to ensure full compatibility – usually free of charge. This ensures no costly or time consuming installation problems. Our charge air coolers have been successfully used on all common turbo charged diesel engines:

Sulzer, B&W, MAN, MAK, Semt Pielstick, Mitsubishi, Wartsila, Yanmar, Mitsui, Cummings, Mirrlees Blackstone, GMT Fiat, Allen, Deutz, Smit Bolnes, Daihatsu, Bergen, Normo, Atlas, Ruston, Hanshin, Polar, Dorman, Stork-Werkspoor.

Problems with poor efficiency, service life or vibration related damage? Not a problem, we can modify and improve OEM designs to solve many issues, resulting in greater reliability and efficiency than OEM units!
