Howden's air preheaters are engineered to meet the demands of your application. We manufacture our air preheaters in modern facilities based around the world and produce bisector, trisector and quadsector arrangements. We can also provide packaged solutions in either vertical or horizontal alignment.
Our proven VN sealing system ensures that Howden heaters have minimal leakage and thus significantly reduce your operating costs. Other benefits of the VN design include a central drive system, advanced cleaning systems and enhanced maintainability.
Using specialised software we can model and accurately predict the operational and cost advantages of our proposals. Environmental considerations and energy costs make it more important than ever to ensure air preheaters are working at optimised levels.
The first company to form a joint venture with Fredrik Ljungström, we have been designing and improving rotary heat exchanger technology ever since.
Continual research, development and analysis of both new and aftermarket heaters to optimise product performance and reliability.
