Electricity? Solid fuels? Oil/gas? Or steam?

Our range of standard boilers extends from 36 kW to 20 MW. Most boilers can, of course, be combined in different solutions. They can produce heat and steam from electricity, oil/gas and solid fuels.

We develop and manufacture all of our boilers in Osby, Sweden.

Solid-fuel boilers.

A complete range from 100 kW to 12 MW. Depending on the market, our solid-fuel boilers are manufactured according to the Pressure Equipment Directive (PED) or ASME standards.

The boilers can be fired with either dry (<35% moisture content) or moist fuels (35-55% moisture content). Our solid-fuel boilers are to a large extent fully automated for easier management. Cleaning of the convection tube package and ash handling are carried out automatically at programmed intervals.

We supply our boilers with a control system that operates and monitors the boiler and can handle the entire boiler installation. The control system can be operated remotely.


For firing with dry wood fuels like pellets, briquettes and chips with up to 30% moisture content. The series includes boilers with an output range of 100–1,000 kW. The P500 can be automatically regulated between 25 and 100% of the design output.



A welded steel boiler for over-pressure and under-pressure firing. Can be fitted with a pellet burner or firing equipment for moist chips. Can also be fitted with an oil/gas burner.
