VRF & VRV air conditioning systems

The gold standard for larger buildings. VRF systems run many indoor units from one outdoor unit, with independent zone control and the efficiency of simultaneous heating and cooling.

Scalable & efficient

One system that scales across the whole building

VRF (Variable Refrigerant Flow) varies the refrigerant to each indoor unit, so every zone gets exactly what it needs. Heat-recovery versions even move warmth from rooms being cooled to rooms being heated.

  • Independent control for every zone
  • Simultaneous heating & cooling (heat recovery)
  • Highly efficient part-load operation
  • Expandable as your building changes
