Walter is a CHP -unit that produces enough electricity and heat for the annual needs of a farm, an entire small housing estate or small business. Our CHP’s can be scaled up to multi-unit installations to meet the needs of growing energy demand across diverse applications. Electricity is produced by gasifying biomass in the form of wood chips. Waste heat from the process can be used in agriculture or industrial processes, hydronic underfloor heating, preheating of air-conditioning or domestic water, to name a few.

Key features

Volter 40 Outdoor


Walter WP is our weatherproof container version of Walter. Ideal solution for a single unit installation with no existing buildings that can be used.

Volt factory

Volt Factory is a product concept, where ten or more modularly scalable Walter CHPs are producing a larger amount of energy. For example, a Volt Factory with ten Walter CHPs, form an energy park with 500 kW of electricity and 1,3 MW of thermal output.

Built to work anywhere, in any weather


Our innovation enables efficient electricity and heat production using your local wood resources. The gasifier is superheating the woodchips into wood gas, which is a fuel for an internal combustion engine that runs the generator and produces electricity. The process also generates heat that can be used for different heating and drying purposes.
