Whichever model you choose, AQUAERA adapts to you.

The AQUAERA models are built on the proven Malmberg technology. Inspired by the strength and vision of Norse mythology, each AQUAERA model carries its own character: from FREJA, designed for smaller-scale operations, to ODEN, built for the largest capacities.
