We use a German made Heizohack HM 8-400 wood chipper. This chips to G30/G50 standards and is designed to produce chip suitable for Biomass boilers, unlike some chippers which create long shreds of wood that can cause blockages. Thanks to some clever engineering, larger wood chips are bounced back to be chipped again and the machine can be operated via remote for safety.
Our wood chipper is crane fed uncontaminated virgin wood and outputs directly into our 30m3 skips to avoid contamination, after a 24 hour stint in the kiln the chip is then delivered directly to the customer. At no point during the production process can contaminants enter the chip.
