Our genuine Ljungström® air preheaters are recognized by end users around the world as the best products of their type.
The first Ljungström air preheater on a commercial boiler reduced fuel consumption by as much as 25%. In modern utility boilers, the Ljungström air preheater contributes up to 20% of the overall boiler efficiency while representing only a fraction of the total investment.
Engineered to our proven design standards and constructed with minimal installation costs, our APH will operate over extended periods, with a durable, uninterrupted service. The Ljungström air preheater is more widely used than any other rotary heat exchanger in the steam generating industry. This is due, in part, to:
- high thermal effectiveness and proven performance
- advanced heat transfer surfaces
- bi-, tri- and quad-sector duct configurations
- rotor and sealing system options with effective leakage control
- outstanding reliability and availability
- compact design
