Economical use of waste heat

Lower footprint and weight
Cleaning possible during operation of engine, turbine or process
Output can be adjusted according to the need
Extend the time in between major cleaning e.g. via dry-run mode
Low enertia

In any operation, there is almost always room to continue reducing power consumption and related costs. The secret is in reclaiming the energy lost as exhaust gas heat. As the pioneer in waste heat recovery, Alfa Laval has the technology and expertise to help you further increase your energy efficiency.

Applications

The Aalborg Micro can operate with a diversity of media, including water, steam, triethylene glycol (TEG) and thermal fluid oil (TFO). To date, Alfa Laval Micro heat exchangers have been used in different applications across a wide range of industries.

Design

The Aalborg Micro is build in a durable design featuring a heating surface consisting of a number of coaxial tubes arranged in a vertical or horizontal cylindrical shell plate. This, ensures a long-term, trouble-free performance and offers capacities ranging from approximately 250-5000 kW.

The heating surface of the Aalborg Micro has been developed for easy maintenance. Cleaning can be performed either with a pyrolysis process when operating in dry-run mode or using optional soot blower rings with compressed air, steam or water.
