Ventilation solutions that help to cut energy bills by up to 36%

Hitachi’s range of 1-way and 2-way ventilation solutions are compatible with VRF and commercial split systems(1). The Dedicated Outside Air System (DOAS) unit is a 1-way solution which brings fresh air into outdoor spaces pre-treating it using the refrigerant loop, while a 2-way energy recovery ventilation (ERV) solution is provided by Energy Recovery Ventilator which recovers energy from exhaust air to bring fresh air closer to the indoor temperature, thereby reducing loading on the AC system and lowering energy consumption.(2)


1. The 1-way ventilation solution - Dedicated Outside Air System (DOAS) - is not compatible with commercial split systems because it integrates with the VRF refrigerant loop
