The best MVHR systems do their job without drawing attention. The Blauberg EcoSlim-900 takes a different approach to heat recovery.
Where many MVHR systems rely on fragile paper exchangers, the EcoSlim-900 is built around a polymer counter-flow core: washable, durable, and designed to last.
It transfers heat, not moisture, keeping the air streams completely separate. Fresh air stays fresh. Exhaust air stays out.
The result is cleaner air quality, with no crossover of humidity or odour, ideal for offices and commercial environments where comfort and reliability matter.
Crossflow units lose energy; the EcoSlim-900 makes it count. Its counter-flow design captures up to 88 % of heat energy, cutting waste and lowering running costs.
There’s no paper to warp, no cores to replace, and no decline in efficiency over time, just quiet, consistent, energy-smart ventilation that works unseen in the background.
