Malmberg introduces AQUAERA™, a next-generation biogas upgrading system built on Malmberg’s 100 % water-based process – chemical-free, energy-efficient, and proven in operation.
The new modular design gives plant owners the freedom to scale capacity and performance over time, from small to large flow rates, while maintaining the high reliability Malmberg is known for.
“With AQUAERA™, we’ve taken everything we’ve learned from decades of operating Malmberg COMPACT units and turned it into a system that’s flexible by design,” says Johan Wahlström, Managing Director at Malmberg Energy.
Each AQUAERA™ model carries its own identity – from FREJA for smaller capacities to ODEN for high-flow systems – all inspired by Nordic mythology and built on the same proven core technology.
