Ever increasing CO2 taxes and oil prices have caused many energy providers to develop production facilities with alternative energy sources.

Berg Jet has decades of experience in fan technology, and we offer customized solutions for incineration, district heating plants, biogas plants as well as other systems utilizing alternative fuels.

Biogas plants often contain aggressive and highly explosive gases. The requirements for component materials managing the gases are stringent.

Berg Jet complies with the demands for perfect sealing and durable materials by manufacturing in AISI 316 and delivering double-welded spiral houses. We equip the fan with continuously lubricated shaft sealing, and we always offer our clients the optional performance of an air proof test.


Berg Jet delivers standard fans for district heating plants fueled with traditional energy sources such as oil and gas, and increasingly, those who utilize alternative energy sources such as wood chips, straw and wood pellets.

The company is a well-established supplier of small and medium sized fans for the transportation of fresh air and flue gasses in connection to all incineration processes. Rising hydrocarbon prices have led more international players to choose alternative energy sources for their companies.


The traditional incineration plant is a large-scale processing plant that supplies heat to a number of households and building complexes. These processes often require a variety of blowers.

Berg Jet has been providing fans for application within this industry for many years. The company is sub-supplier for several international companies and delivers directly for Danish and Swedish plants.

Our fans supply the process with combustion air, and their performance is determined by the boiler’s current requirements for air during the incineration process. The volume of air is regulated either by means of a damper on the fan’s suction side or by using a frequency converter.

In order to exploit the energy content of the waste gases, they are fed through a heat exchange before being released into the atmosphere. By this point, their temperature is so low that no natural chimney draught can be formed, and the flue gases must therefore be helped on their way by a flue gas fan. The flue gas fan also functions to establish a partial vacuum in the boiler in order to minimize the risk of gas leaks into the atmosphere.
