Proposal would phase out use of R-134a, R-410A, and R-407C in chillers
February 4, 2016
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and the Natural Resources Defense Council (NRDC) issued a joint letter to the U.S. Environmental Protection Agency (EPA) in support of changing the status of certain refrigerants used in liquid chillers under the Significant New Alternatives Policy (SNAP) program effective Jan. 1, 2025.
The complete line now offers units from 165 to 1,000 tons

Johnson Controls announced it has expanded its magnetic-bearing centrifugal chiller line, the York YMC2, to 1,000 tons of cooling (3,500 kW). The larger cooling capacity units address the need for reduced sound, high efficiency, and low maintenance as well as featuring magnetic bearing and oil free technology.
Alternative to R-134a provides 56 percent lower GWP and comparable performance

Johnson Controls announced it is enhancing its HFC product lines to be fully compatible with the non-flammable, low-global warming potential (GWP) refrigerant Opteon™ XP10 (R-513A) manufactured by The Chemours Co. York centrifugal and screw chillers ranging from 125 to 6,000 tons (440 to 21,100 kW) are compatible with R-513A.
Johnson Controls is buying 60 percent of that business and creating a joint venture with Hitachi Appliances retaining ownership of the remaining 40 percent. The new business is valued at around $2.8 billion.
XL Catlin and Financial Risk Solutions Inc. have entered an exclusive underwriting agreement to offer Chill-Pro® contractual liability insurance coverage for HVAC contractors in the U.S. Chill-Pro is a national insurance program that provides service agreement coverage for chillers.
Chillers provide high performance in a compact size

Mitsubishi Heavy Industries Ltd. (MHI) has developed a new series of centrifugal chillers, called the ETI-Z Series, that use a new low-global warming potential (low-GWP) refrigerant, HFO-1233zd(E). The various models in the new series will be progressively launched starting this September.
The chillers increase energy efficiency and reduce environmental impact

Trane, a brand of Ingersoll Rand, has introduced the Trane® Sintesis™ family of air-cooled chillers, which are engineered to use the low-global warming potential (GWP) refrigerant R-513A. The chillers are now available for order in North America, Latin America, Europe, and the Middle East.
Even as the economy has improved, some building owners and operators remain hesitant to make large capital expenditures to replace older chiller systems. In these cases, there are less expensive options available that can enable decision makers to achieve substantial efficiency upgrades by retrofitting their chillers.
When it comes to large commercial systems, cooling towers seem to receive less attention than other system components. Yet, cooling tower maintenance is vital to ensuring overall system efficiency and preventing downtime.
