Yes, the HRA-I PLUS is suitable for both retrofit and new construction. Since it requires only a core wall penetration and standard electrical connection, it can be added to existing buildings with minimal structural impact or included in the planning phase of new developments.

Unlike central HRV systems that rely on ductwork, the HRA-I PLUS is a decentralized unit that installs any where in the unit and ducted out, serving individual rooms. It offers independent operation, simpler installation, and significantly less space requirement—while still delivering high-performance heat recovery and ventilation. Also new HRAI model comes with 1 KW pre heater option makes it idle for lower ambient applications.
