What Is Hybrid VRF?

Hybrid VRF is the world’s first patented two-pipe system that uses a unique Hybrid Branch Circuit (HBC) Controller to transfer heat between refrigerant and water. This drastically reduces refrigerant use and keeps all indoor piping refrigerant-free—a major benefit for buildings that prioritize occupant safety, energy efficiency, and regulatory compliance.

The system allows for simultaneous heating and cooling, offering precise temperature control in every zone of your building. Unlike traditional VRF, Hybrid VRF replaces indoor refrigerant lines with water piping, minimizing leak detection costs and meeting increasingly strict environmental standards.

Why Choose Hybrid VRF?

Future-Proof and Regulation-Ready

With 30–40% less refrigerant per system and no refrigerant in occupied spaces, Hybrid VRF helps future-proof your building against evolving sustainability standards. It’s also compatible with lower-GWP refrigerants, reducing your long-term carbon footprint.

Faster, More Flexible Installation

Hybrid VRF uses the same CITY MULTI N-Generation outdoor units as standard VRF systems but requires fewer materials and less space. Thanks to its two-pipe design and modular layout, it’s scalable for everything from historic renovations to new high-rises.

Indoor Installation and Extreme Performance

WR2-Series units can be installed indoors, ensuring reliable performance regardless of outdoor temperatures. Plus, the system can share energy across condenser loops, boosting overall efficiency.

Safe, Stable Comfort

With no refrigerant in indoor spaces, Hybrid VRF is ideal for schools, hospitals, hotels, and offices. It delivers consistent air temperatures using hydronic heating and cooling, creating a more stable and comfortable environment for occupants.
