Designed and built in Bavaria, Germany since 1982. The New Heizohack HM4-300 Wood Chipper is a tractor PTO driven chipper. The 600mm in-feed conveyor takes the wood to the powerful 380mm diameter (variable speed c/w stress control feature) feed roller which then presents the material to the 4 blades which handle up to 300mm solid timber. The G30 biomass chips produced are then blown out of the discharge chute into your boiler’s chip store or into a trailer ready for delivery. Offering efficient, safe and profitable biomass chip production. If you have any questions regarding the Heizohack HM4-300 Chipper, please contact us for assistance. When processing wood as a raw material, what counts for forestry companies, forest farmers’ cooperatives and contractors is speed, time-saving and perfect chopping results. Based on practical experience, Heizomat have therefore designed professional machines that accommodate all of your needs and are essential for the production of wood chips.   “Energy in Balance with Nature” has been Heizomat’s guiding principle ever since Robert Bloos founded the firm in 1982. To this day, it is rigorously pursued. Extremely high and volatile raw material prices argue in favour of Heizomat’s highly efficient biomass and wood chip boilers, with outputs ranging from 15 to 990kW.
