Our products

Water-cooled intercoolers

For compressed cathode air cooling in hydrogen fuel cell power trains and internal combustion engine charge air cooling, our water-cooled intercoolers are capable of effectiveness values of over 99% – while still being incredibly lightweight. The ring-shaped design increases side air-flow and drastically reduces pressure drop.

Condensers/evaporators

Our microtube, straight-rack condenser/evaporator units are ideal for thermal lift systems where mass is critical, including batteries, electronics and power cells. Small-diameter tubes maximise heat transfer coefficient at minimum mass. With no internal cavities for condensate pooling, wet mass is reduced and the amount of fluid inside remains constant.

Waste heat recovery heat exchangers

Our heat exchange technology is perfect for recovering waste heat from the exhaust gases produced in any green fuel cycle (e.g. ammonia-burning or hydrogen-burning cycles). Designed for low pressure drops on both fluid streams, they enable retrofit and higher system efficiencies.
