Mitsubishi Electric | Lossnay Heat Recovery Ventilation

The secret of the LOSSNAY system lies in the cross-flow, plate-fin structure of the heat exchange unit (LOSSNAY core).

A diaphragm made of specially processed paper fully separates the inlet and exhaust air supplies, ensuring that only fresh air is introduced to the indoor environment. The superior heat transfer and moisture permeability of the special paper ensures highly efficient total heat exchange (temperature and humidity) when the inlet and exhaust air supplies cross in the LOSSNAY element.
