Replacing the industry leading T4 wood chip boilers, the T4e is a modern answer to flexible biomass boilers.  Able to burn a variety of fuels (Woodchip, Pellet) with a vast array of fuel feed systems, the T4e also is able to have electrostatic filters fitted internally to the boiler, as well as multi cyclone filters on the flue gasses, to give the absolute minimum in dust emissions, making the boilers as clean as a fossil fuel boiler.
