RECOM 6 SR EC Rotary Heat Recovery Unit
High-capacity rotary air handling unit for spacious homes and commercial spaces
Enjoy pure and fresh air even in the largest spaces. The RECOM 6 series units reach an impressive 670 m³/h capacity, making them ideal for spacious homes. The rotary heat exchanger ensures efficient heat and moisture recovery without the need for any condensate drainage.
High capacity - 670 m³/h
Powerful yet economical EC motors guarantee smooth air exchange in large-area homes or commercial spaces.
Natural moisture balance
Rotary and sorption (SRS) models prevent indoor air from drying out during the heating season, thus protecting your health.
No condensate drainage
Unlike plate heat exchangers, this system does not require the installation of a condensate drainage system, making installation easier.
Why choose RECOM 6 SR/SRS EC?
Large spaces require exceptional performance and reliability. The RECOM 6 series, capable of reaching an airflow of up to 670 m³/h, is the most powerful choice in this segment. Despite its high power, thanks to modern EC motors and good casing insulation, it operates economically and without excessive noise.
Technology that saves moisture and your time
One of the most appreciated features of rotary air handling units is that they do not require condensate drainage. Condensate formed on the rotating drum during winter is evaporated back into the supply air. By choosing the sorption (SRS) model, this moisture recovery effect becomes even stronger – meaning healthy skin, thriving houseplants, and better sleep without the need for additional air humidifiers.
Complete ventilation system with RECOM
A powerful air handling unit requires an appropriately sized duct system. RECOM 6 models are equipped with 200 mm duct connections. To ensure even and quiet air distribution in a large house, the ORO Haus team will help design the system and select the right silencers and distribution boxes.

Since the RECOM 6 SR series air handling units are characterized by large dimensions and high capacity, special attention must be paid to mounting and noise isolation during installation.
What is in the box
In the standard package you will receive:
- Fully assembled air handling unit with a rotary heat exchanger
- Filter set (installed in the unit)
- Installation and user manual
What you will need additionally
For a successful and high-quality installation, prepare:
- Strong mounting hardware suited for the heavy weight of the unit
- Vibration isolation rubbers or pads
- 200 mm diameter ducts and flexible connectors for vibration dampening
- Control panel and its designated wire
Dimensions and location selection
Choose a sturdy wall and provide clear access from the front of at least 70-80 cm. This will ensure that you can easily open the doors, change filters, and perform maintenance in the future.
Duct connection
RECOM 6 SR uses 200 mm spigots. For a unit of this size, it is highly recommended to use flexible canvas connectors between the air handling unit and the main ducts to prevent vibration transmission to the home's walls.
Condensate drainage
One of the greatest advantages of this model is that there is no need to run condensate drainage pipes and install a siphon during installation.
Electrical connection
The unit requires a stationary power connection to a 230V network. All wiring, circuit breaker selection, and connection work must be performed by a certified electrician.
First start
After successful connection, the main parameters are configured on the control panel. It is essential to perform airflow balancing at all diffusers in the home.
Maintenance and filters
Due to the large volume of flowing air, it is recommended to check the filters every 3 months. At least once a year, vacuum the rotary heat exchanger to remove accumulated dust.
