VRF Heat Recovery Ventilation

Built-in high-efficiency filters and a CO₂ sensor ensure clean, controlled airflow, automatically adjusting performance to suit indoor conditions.

The unit’s slim and compact design allows the HRV to be installed easily where space is limited. No drain piping is required, as both sensible and latent heat are transferred through the heat exchanger.

A 2-core wired 7-day controller can be used to control multiple units simultaneously.

Built-in as standard, F7 filter for air supply side and M5 filter for exhaust air.

Built-in as standard allows control of fan speed according to CO2 concentration.

Heat Exchange Mode: The flows of incoming and outgoing air pass close to each other, allowing heat transfer between the two channels. During summer, incoming air is cooled by the indoor air being exhausted and in winter, incoming air is warmed.
Bypass Mode: Supply and exhaust fans run at the same speed. In mild climates, where temperature and humidity differences between indoor and outdoor are small, the HRV can work as a conventional ventilation fan.
Air Supply Mode: Supply fan runs faster than exhaust fan. A mode suitable in mild climate installations with fresh air ventilation requirements.
Exhaust Mode: Exhaust fan runs faster than supply fan. A mode suitable in mild climate installations with large amounts of exhaust air to be expelled.
Auto Mode: The controller chooses heat exchange mode or bypass mode according to temperature difference between outdoors and indoors. Both fans run at low speed.
