In 1920, Fredrik Ljungström imagined how he could improve ventilation without losing heat, and two years later, the first Ljungström® air preheater was installed in a chocolate factory.
It has been estimated that, since 1920, the use of Ljungström air preheaters has achieved worldwide fuel savings of over 5 billion tons of oil. The typical customer can see the cost of a preheater recovered after only a few months of operation.
Globally, Ljungström air preheaters save billions of dollars annually, and provides up to 25% less fuel consumption, contributing to a more sustainable and energy efficient world.
LJUNGSTRÖM has a long history of innovative problem-solving and customer service.
