Popular solution across the world

Variable Refrigerant Flow systems (VRF) are quickly becoming popular for air conditioning solutions across the world. VRF systems not only provide flexible and energy efficient air conditioning, but also heating and hot water for residential and commercial applications.

Some of the features of this type of an air conditioning system with variable refrigerant flow include:

  • Cooling only, or reversible for heating, including heat recovery options
  • Air or water cooled systems
  • Variable capacity compressors
  • Optimised for a number of conventional and environmental refrigerants
  • Up to 64 indoor units with individual metering

Features and benefits

Compact, space-saving components

High energy efficiency

Optimised for environmentally friendly, low GWP refrigerants

Reduced applied costs and short payback times
