Thermofluidics’ globally-patented technology uses physical phenomena to pump water without precision moving parts. It has applications in many industrial, domestic and agricultural sectors, but our core focus areas are agriculture, building services, drinking water and sanitation.
Our Double-Acting Hydraulic Ram (DAHR) pumps can use a wide range of surface power sources to lift water from deep below ground and provide surface pressure for filtration and distribution. Our Non-Inertive-Feedback Thermofluidic Engine (NIFTE) uses low-grade heat to pump against heads of up to 10m.
With only three non-return valves and no other moving parts, the DAHR has proven ability to lift water from up to 60m depth, and can theoretically lift from much greater depths. At the current stage of development, it achieves hydraulic efficiencies of between 70% and 80% across a wide range of heads and flows. It is insensitive to variations in water depth (draw down) and can be driven by most appropriately-sized surface drive pumps operating at close to their Best Efficiency Points (BEPs).
With only two non-return (check) valves and no other moving parts, NIFTE can currently pump flows of up to 1L/s at 3m head and close to 0.5L/s at 10m head (1 bar). The technology is also highly scalable.
Owing to their lack of sliding seals and precision parts, the DAHR and NIFTE can be constructed from common plastics, aluminium alloys and steels, using processes such as extrusion, sand-casting, die-casting, pressing/forming and injection-moulding. This makes them cheap, reliable and easy to maintain.
The DAHR has a peak hydraulic efficiency of over 80%, mainly as a result of its minimal friction losses. The NIFTE has demonstrated peak thermal efficiencies which are unprecedented for heat sources at such low temperatures.
We believe that our award winning technologies can play an important role in helping to solve some of the world’s greatest environmental and humanitarian problems and we hope that this website will evidence that. To that end, we have uploaded information on the accompanying pages which we update periodically. If you would like further information, please get in touch via our contact page.
