• It's no coincidence that we're the best at what we do.
  • Bioenergy plants for biomass combustion

Jernforsen produces complete bioenergy plants for heat production. The facilities are operated with biomass, ie. forest products such as wood, wood chips, bark and pellets.

We manufacture customized systems that are divided into the following categories:


We enter each assignment to create the best solution for the customer's needs, requirements and opportunities. A close dialogue and discussion are important aspects of advising you about the optimal choice of bioenergy plants.

Project development

Jernforsen becomes your innovative partner, developing and adapting bioenergy plants to your requirements and specifications. Our patented combustion technology ensures high efficiency and optimizes operating costs.


Jernforsen is a flexible company that works closely together with its clients. We believe in good service - even after the project ends, and we take pride in having the plants run optimally. You can choose us for ongoing maintenance and service.

Jernforsen develops and installs bioenergy plants from 4-35 MW and has strong expertise in the combustion of biomass waste (including recycled wood and other types of biomass waste), as well as "wet" fuel.

Linka Energy is a specialist in the development, design and construction of fully automated bioenergy plants from 2.5 - 15 MW. The primary types of fuel are straw, wood chips and wood pellets, but more exotic fuels can also be used.

Weiss is an advisory and executive service company specializing in servicing, supplying spare parts, advising remote and district heating plants and other customers. Weiss also works with the production of major plant components and plant optimizations.


Fullservice partner

We are involved from the beginning of the project planning. Either as a subproject for our part of the boiler house, or as a commitment to take on the full project.


Many years of experience

Jernforsen was founded in 1984 and has delivered bioenergy solutions to properties, wood Industries and sawmills as well as district heating customers  for generations.
