Airflows from 250 to 2,000m³/h. The Hitachi heat recovery ventilation system (KPI) adjusts the temperature and humidity of incoming fresh air to match the indoor environment.
Low noise level. ErP lot 11 complaint fan motors resulting in low noise levels of 24b(BA).
High-efficient exchanger with the following features:
- Controlled with Hitachi System Free PC-ARFGE Controller
- Fresh air supply for indoor environments.
- Energy recovery ventilation between supply and extract air supplies (forced energy mode) efficiencies up to 78%
- Automatic ventilation (KPI controls which mode to operate within to achieve maximum energy)
- Ventilation mode (forced bypass mode)
