York chillers compatible with R513A

York-R513AUSA: York centrifugal and screw chillers from 440 to 21,100kW are now compatible with R513A, the lower GWP alternative for R134a.

Johnson Controls says it will showcase this new offering at next week’s AHR Expo.

“Our customers can have peace of mind when specifying or purchasing current R134a-based product offerings, knowing their purchase will provide the full economic benefit, regardless of any potential HFC regulations during the life span of their equipment,” said Laura Wand, vice president, Building Efficiency global chiller business, Johnson Controls.

 “Just as we addressed ozone depletion years ago, specifically with regard to CFCs and HCFCs, we discontinued the use of R123-based products to avoid potential obsolescence of equipment in the later stages of equipment lifetime,” said Wand. “Our chillers are ready for the future,” she added.

Johnson Controls told the Cooling Post that R513A is essentially a drop-in to its existing equipment, compatible with the existing oil and materials of construction (gaskets, o-rings, etc).

Tests are said to have shown good correlation to R134a overall in both capacity and efficiency.  Performance ratings and retrofit services will be announced later this year

R513A, sold by DuPont as Opteon XP10, is a binary mixture of R134a (44%) and R1234yf (56%). It has a GWP of around 630 and carries the ASHRAE safety classification of A1.
