Oil-free compressors maintain consistent performance over time
Danfoss conducted a study to see how long term operation affected performance on Danfoss Turbocor® compressors. The results showed that oil-free, magnetic bearing compressors maintained consistent performance even after 10+ years of operation.

Compressors for refrigeration
Danfoss focuses on providing energy efficient, sustainable and smart refrigeration compressors for a varied range of commercial applications such as cold rooms, display windows, ice making machines, glass door merchandizers, process cooling etc. Their qualification with lower GWP refrigerants make them compliant with refrigerant regulations such as F-Gas in Europe.
NRV refrigeration check valves
NRV and NRVH can be used in liquid, suction and hot gas lines in refrigeration and air conditioning plants with fluorinated refrigerants. NRV and NRVH can be supplied with flare and solder connections. They are also available with oversize solder connections providing flexibility in the use of check valves.
ETS electric expansion valves
ETS is a series of electric expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications. The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions. ETS valves are compatible with electronic control solutions from Danfoss and other manufacturers.

A step towards more environmentally friendly AC systems and heat pumps
Seen from a global perspective, the tendency is that the industry is moving more and more toward natural refrigerants where this is technologically feasible Synthetic refrigerants are still likely to play a large role in the refrigeration and air conditioning industry, but this will be in systems with the smallest possible charge of refrigerant and with new low GWP substances
Components for heat pumps – part 6: electronic injection control for evaporators
Users of heat pumps are concerned both to maintain an optimum evaporator charge, but with the usual thermostatic expansion valves it is often not possible Electronic expansion valves, however, are ideal for this purpose
