The new Hybrid VRF (H-VRF) system uses an innovative combination of VRF technology linked to water based fan coils.

Refrigerant is only used in pipework between the external condensing unit and the Hybrid Branch Controller (HBC). Water is then used to transfer the energy from the HBC to each bedroom to supply hot or cold water to each fan coil as necessary.
H-VRF is particularly suited to hotels as there is no refrigerant in the bedrooms, just water. This complies with BS EN378 recommendations, so there is no need for leak detection.
Simultaneous heating and cooling with full heat recovery between fan coils and building zones
Heat recovery defrost method enables typical defrost times of 5 minutes with immediate return to heating
