LUNOS
Decentralized heat-recovery ventilation built into the exterior wall.
What they're known for
Compact through-wall ventilation systems for new construction and retrofit, including North American versions of the e² platform.
LUNOS develops decentralized residential ventilation systems that recover heat without requiring a central duct network. The e² platform mounts through the exterior wall and uses regenerative heat exchange, allowing it to serve bedrooms and living spaces in both new construction and retrofit work. North American versions are engineered for US and Canadian requirements. For Compound, LUNOS is useful because it represents a different ventilation architecture from a conventional central ERV: room-by-room heat recovery with minimal distribution infrastructure.
