Engineered For Excellence

Refrigerants for Data Centers

Solstice® refrigerants are engineered to deliver room and precision air conditioning in data centers. As chips and electronics become hotter and more powerful, two-phase liquid cooling solutions using Solstice®  fluids enable energy-efficient uniform cooling, offer better heat rejection and reduced pumping power. The applications include: Room and precision air conditioning and Liquid Cooling (cold plates)

Boost Performance and Reduce Emissions

Stay ahead of regulatory requirements

Solstice® molecules have zero ozone depleting potential and a short atmospheric life, reducing environmental impact and facilitating regulatory compliance.

Reduce global warming impact

Solstice® HFO refrigerants have an ultra-low GWP as low as 1 and can be used in heat-recovery systems to enable net-zero capabilities.

Keep it cool and Keep costs down

Enjoy lower energy costs due to high system efficiency and reduced maintenance expenditures.

Safety and peace of mind

A1 and A2L class components are easy to transport, handle, install and maintain.

A1 Refrigerants for Data Centers

Solstice zd 

Solstice® zd (R-1233zd)

Nonflammable (A1), ultra-low GWP of <1, offering better capacity and similar efficiency to R-123. Addresses the challenging environmental needs of different industries like centrifugal chillers and high-temperature heat pumps.

Solstice N15 

Solstice® N15 (R-515B)

GWP of 293, nonflammable (A1) azeotropic blend that demonstrates environmental and performance benefits in new systems. Matches the capacity and efficiency of R-1234ze, hence it can be used in all equipment that has been designed for R-1234ze.

Solstice N13 

Solstice® 513A - (R-513A)

A non-ozone depleting, low global warming potential (GWP) hydrofluoroolefin (HFO)- based refrigerant developed to replace R-134a.


A2L Refrigerants for Data Centers

Solstice 454B 

Solstice® 454B (R-454B)

Mildly flammable (A2L refrigerant), non-ozone depleting, zeotropic blend with improved efficiency and matching capacity to R-410A and with a GWP that’s 78% lower, minimizing redesign costs and capital expenditures. Most optimized R-410A replacement, providing easy conversion with minimal changes from an R-410A design.

Solstice ZE 

Solstice® ze (R-1234ze)

Mildly flammable (A2L refrigerant), ultra-low GWP and energy-efficient alternative to R-134a in air-cooled and water-cooled chillers and heat pumps.
