Our New Technology

An electrostatic precipitator capable of removing particles from a gas stream. Particles entering the device are charged by a high voltage electrode and then attracted to an electrode of opposite charge within the device, removing them from the gas flow.

The prototype device has a high efficiency, based on the capture of wood smoke, removing 98% of particulates between 0.1 and 2.5 µm in diameter, 91% of particulates between 2.5 and 10 µm in diameter and 95% of particles overall. Further refinements in design are expected to increase this efficiency.


The unique design features of the device mean that it can be made much smaller than existing electrostatic precipitators. The simplicity of the design means that manufacturing and operating costs are minimal, allowing widespread deployment. The device is particularly efficient at capturing smaller particles, which are difficult to remove using conventional filters.


The miniature ESP was designed to capture smoke from wood-burning furnaces, which it performs extremely well. Initial trials that it has the potential for other particle-removing applications, including the removal of atmospheric pollution. Further developments could include removal of particulates from diesel exhausts.


Available for licensing in its current state of development, or for collaborative research agreements to develop specific applications and configurations. Licences will be granted for specific applications, but will available worldwide if required.
