Majordomo FR (Freshness Recovery) for private houses with an exhaust fan

The energy efficiency of this device is comparable to MVHR-equipped systems. Achieved through adaptability
Improves air quality by maintaining comfortable CO2 and humidity levels
Reduces  the load on the equipment.
Prevent mold
from developing
Reduces heating costs

Majordomo FR increases energy efficiency of the ventilation system with an exhaust fan

The air quality management system, consisting of a control device, Majordomo FR algorithm and exhaust fan, takes over the function of sorting and redistributing the air flows inside the house or apartment according to the intensity of room use.
Majordomo FR is designed primarily for summer houses and houses of permanent residence, where the installation of an MVHR system is not reasonable
The system effectively prevents mold growth and maintains a comfortable environment through flexible and control of the exhaust fan and individual distribution of air flows inside the house.

Using Natural Dynamics air quality management system not only allows you to choose a more affordable ventilation system, but also allows you to realize ongoing savings on your operating costs (primarily on energy costs for space heating).
