The Alfa Laval Aalborg Micro is a uniquely compact water-tube economizer. Easy to install, operate and maintain, it reduces the use of the fired marine boiler by recovering heat energy that otherwise would be lost through the engine exhaust gas. Despite its minimal footprint, height and weight, the Aalborg Micro has an extended heating surface created by coiled fin tubes. Even more efficient than smoke-tube economizers, it provides an ideal retrofit solution where no other economizer will fit.
The most compact and efficient economizer available
- Extremely compact, plug-and-play design for easy retrofit
- Easy improvement of Carbon Intensity Indicator (CII)
- Short payback time (typically 1–2 years) through up to 25% fuel savings on the oil-fired boiler
- Reduced wear and maintenance on the fired boiler
- Internal damper for dynamic management of pressure drop
