However, we’re all too aware that when production trains are taken out of service, lost revenue can be severe.

Fortunately, our replacement services are speedy and hassle-free so that you can be up and running again in no time at all. LJUNGSTRÖM replacement units are generally a drop-in design, attaching directly to your existing support foundations. Duct connections are also usually a direct fit-up, and expansion joints are renewed simultaneously. Depending on the availability of adequate tools and personnel, we can have your air preheater replaced within 48 hours.
Additionally, our smaller sized air preheaters ship to your site fully assembled and ready to drop into place in a single lift. While our larger units need to be shipped in parts, these can be assembled on site to facilitate a single lift installation.
