FeTu Ltd.
Established in 2016 by Jonathan Fenton, CEO, FeTu Ltd are an Innovation Driven Enterprise that has created a simple heat engine, a revolutionary ‘green’ energy device targeting carbon reduction across a broad range of energy systems and industries, with IP in the ‘Global top 40’ territories. Multi-award winning, most recently, the Institute of Physics (IOP) Business Innovation Award.
The FeTu technology, likened to a heart, is a four-chamber ‘energy motor’ that has proven its ability to outperform current compressors, pumps, and Organic Rankine Cycle (ORC) heat engines. A ground-breaking natural gas beating heat-pump has also been developed.
This is a British brand that innovates, designs and manufactures in-house using world-class 5-axis CNC machine tools to exacting time and cost-effective quality standards.
High-Temperature Heat Pumps
The unique, patented architecture of this new engine generation is pure of form and idealised by function, a simple, elegant, energy motor with ruthless class-leading efficiency. Its unique ‘continuous flow + positive displacement’ functionality combines the benefits of both centrifugal and reciprocating piston engines. Cycling four fluid displacement chambers per revolution in a balanced, power-dense and compact design.
Utilising a FeTu machine as a Compressorwithin a vapour-compression cycle holds the highest heat pump efficiency, defined as the Coefficient of Performance (COP). This thermodynamic cycle involves using input work to pressurise a fluid to high pressure and temperature and using this temperature to transfer heat to an external body.
The chambers collapse to zero volume (500:1), providing easy access to a wide range of Volume Ratios from 1:1 to 10:1, with incredibly high Volumetric Efficiency (+95%).
Internal parts have no contact other than ‘frictionless’ bearings. A double-acting action means the dynamic internals have equal exposure to suction and discharge zones, yielding a self-cooling, low-friction design of ultra-high thermo-mechanical efficiency (+95%).
High Temperature Heat Pumps, especially those achieving +100°C to raise steam, are highly sought after. The difficulty with achieving high temperatures is the larger Pressure Ratio, which in turn requires a larger Volume Ratio (VR) in the Compressor. Typical VR of a Screw compressor is 5, and a Scroll is 3; therefore, current systems need to multistage the compression to boost the temperature lift, which inherently amplifies efficiency losses. FeTu are not bound by such single-stage VR limitations.
When comparing FeTu to the current HP state-of-the-art (SOA), an 80°C lift @ COP 4 makes for a system which is more cost-effective to operate than a SOA gas boiler.
