2. TECHNICAL INFORMATION
2.1. INTRODUCTION
ORKA HR ensures optimal ventilation of the house with maximum energy recovery. Stale air is extracted from the
“wet” rooms (bathrooms, toilets, laundry rooms, etc.) and fresh air is supplied into the main “habitable” rooms (living
room, bedrooms,studys,...). Both airflows are filtered before forwarding to the heat recovery unit, where warmth from
the stale, outgoing air is transferred to the cooler incoming airflow. The unit performance can reach:
• HR: 92%
• ST:70%
