Thermofluidics’ globally-patented technology exploits recent advances in thermo-fluid mechanics to pump fluids without precision moving parts. Our Non-Inertive-Feedback Thermofluidic Engine (NIFTE) generates powerful fluid oscillations using a heat source that can be as little as 30ºC hotter than the pumped fluid, as its only energy input.

With two non-return (check) valves, NIFTE can currently pump flows of up to 1L/s at 3m head and more than 0.5L/s at over 8m head (0.8 bar). These figures are increasing by the day, and the technology is highly scalable. Alternatively, it can be used in conjunction with our patented Double-Acting-Hydraulic-Ram (DAHR), which converts fluid oscillations into acoustic shock waves, enabling water to be drawn from up to 100m below ground and pressurised at the surface. The NIFTE is well suited to a wide range of applications using solar thermal water heaters, flue gases, or other sources of waste heat as a power source. It is also suited to applications where simultaneous heating and pumping are required. The DAHR can be powered by NIFTE, or more or less any oscillatory power source such as hand pumps, treadle pumps or wind-power. We have recently added a computer-controlled Valved Pumping Engine to our portfolio, for very large flow rates up to 40L/s.

Owing to their lack of sliding seals and precision parts, the NIFTE and DAHR can be constructed from common plastics, aluminium and mild-steel, using processes such as extrusion, sand-casting and injection-moulding. This makes them cheap, reliable and easy to maintain.

After more than 10 years of Research and Development in the universities of Cambridge, Exeter and Oxford, the NIFTE has demonstrated peak thermal efficiencies which are unprecedented for heat sources at such low temperatures. The DAHR has a peak hydraulic efficiency of over 80%, mainly as a result of its minimal friction losses.

We believe that our award winning technologies can play an important role in helping to solve some of worlds greatest environmental and humanitarian problems and we hope that this website will convince you to agree. To that end, we have uploaded a lot of information on the accompanying pages which we update regularly, but if you would like further information, please get in touch via our contact page.
