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
Dedicated technical and customer service around the world
Eco labelling options

Pressure switches and thermostats for refrigeration
The range of pressure switches and thermostats cover a lot of applications within refrigeration and air conditioning. The pressure switches and thermostats are in two categories: KP as standard and RT for heavy duty purposes. The switches can be delivered for fluorinated refrigerants as well as ammonia.
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.
