Alfaflame wood chips hot air heating solutions

Alfaflame Oy designs and manufactures wood chips hot air stoves, containers, and storage systems. Turnkey delivery also includes control automation. AlfaFlame Oy is a Finnish family company that was founded in the beginning of 2013. The company shareholders have years of experience on grain dryer and furnace design as well as sales of agricultural machinery. Bio-heat is also used as the primary method of drying grain on the farm owned and operated by our shareholders. The company is located in Southern Finland in the Salo region. Designing and manufacturing our own products gives us a competitive edge over other companies in the industry. We produce burners, air furnaces, storage systems, flue gas extractors and control automation by ourselves. By designing our own products, we can make sure that all our devices are compatible and functional with each other. When you purchase machinery from different manufacturers, compatibility is not your only issue: you will also be juggling different instruction manuals, warranties and interface functionalities. Buying straight from the manufacturer also means lower prices for you. We personally install the products and train you to use them. References available upon request!
