“Thermofluidics' technology is applicable from industrial state-of-the-art to the poorest people in the world - it is our objective to serve both.
We do not have any openings at present. However we are always interested in hearing from talented individuals who share our ethos. Please contact us.


Thermofluidics was formed in February 2006. Since then, we have developed a portfolio of technologies and now have a range of water pumping solutions to address a variety of challenges in the agricultural and building services sectors. We’re able to achieve unprecedented low cost and long lifetime by eliminating sliding seals and complex mechanism using our expertise in thermo- and fluid- dynamics. Our pumps are able to achieve high operating efficiencies relative to competing alternatives in the market today. Key to achieving this are the following people:
