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
  • Optimized for a number of conventional and environmental refrigerants
  • Up to 64 indoor units with individual metering

Features and benefits

    Sight glasses

    SGP is a series of sight glasses for high pressure applications (Max Working Pressure 52 bar/754 psig). SGP is available in versions optimized for refrigerants with mineral oil e.g. HCFC, and in versions optimized for non-flammable HFC refrigerants. SGP is available with flare, solder and socket connections, and with and without moisture indicators.
