The YORK YVFA Free-Cooling, Variable-Speed Screw Chiller is the first free-cooling screw chiller in the U.S. to use R-1234ze, a refrigerant with ultra-low global warming potential.

As the US moves to phase down HFC refrigerants, Johnson Controls has launched its first chillers using lower GWP refrigerants R454B and R1234ze in the USA.

Johnson Controls’ new York YZ centrifugal chiller is said to be the first such machine designed specifically for use with low GWP refrigerant R1233zd and using magnetic bearing technology.
