Solstice® zd (R-1233zd)

Solstice® zd is a non-flammable, ultra-low GWP replacement for R-123 for low pressure centrifugal chillers offering better capacity and similar efficiency to R-123.

Use in low pressure centrifugal chillers, which are most often used to cool large buildings. Trane, a leading air conditioner manufacturer, has already announced that it will use Solstice zd in its new Series E CenTraVac large capacity centrifugal chillers in Europe, the Middle East and other 50hz markets.
