How Does the Twinfresh Comfo RA1-50-2 Work?
This ERV operates in a cycling "regeneration" mode, alternating between supply and exhaust every 70 seconds:
- Exhaust Mode – Stale indoor air is removed while its heat energy is captured by the ceramic core.
- Supply Mode – Fresh outdoor air passes through the ceramic core, absorbing stored heat before entering the room.
This continuous exchange ensures a steady supply of fresh, tempered air without losing energy efficiency.
