Alfa Laval Aalborg (ehem. Aalborg Industries, 2011 übernommen) ist der weltweit führende Hersteller von Schiffs-Abgaswärmetauschern und Kesseln. Die AQ-Serie Abgaseconomiser nutzt die Abwärme der Hauptmaschine zur Dampferzeugung oder Frischwasser-Vorwärmung. Sootfires (Rußbrände) in Economisern sind eine der häufigsten Brandursachen auf Seeschiffen — tägliches Rußblasen ist SOLAS-kritisch.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
