We specialize in maintaining regenerative airheaters with a core focus on industry standard Ljungström airheaters. Since Fredrik Ljungström’s invention was revealed in 1920, this simple, reliable, and proven airheater design has become an industry standard product for many large steam generators around the world. Although the overall design is simple, there are numerous mechanical and operational factors that require attention to detail. These details include proper settings, sealing and mechanical maintenance practices employed to ensure optimal heat transfer, efficiency, and minimize leakages between the air and flue gas ducts.
