Air Conditioning, Refrigeration and Heating

As refrigeration is a key component of your business, the choice of refrigerant matters. That’s why, the decision about choosing the right refrigerant is as much commercial, as much it’s technical.

Honeywell has invested a billion dollars in research, development, and new capacity for Solstice® HFO technology to help businesses transition to lower-carbon future and deliver outstanding business results. Whether you’re building new or retrofitting an existing refrigeration system, Honeywell has the expertise to help you meet energy efficiency and sustainability goals, without sacrificing system performance.

We invite you to speak with our expects to discuss how choosing a right refrigerant can help you achieve better business outcomes.

Chillers and Heat Pumps

More than 90 percent of a chiller’s cost is the electricity consumption over its lifetime, so the return on investment in an energy efficiency refrigeration solution is extremely high over the life of the chiller. Honeywell Solstice solutions are designed for medium pressure chillers to cool large buildings, infrastructure projects, process chillers in refrigeration applications, district cooling and heating and high-temperature heat pumps

Solstice zd and Solstice ze:

  • Solstice ze is mildly flammable and non-corrosive in comparison to ammonia, which is toxic and highly corrosive, and can pose serious risks to human health. Solstice® ze offers significant improved efficiency in Chiller applications over ammonia*. Based on Honeywell’s hydrofluoro-olefin (HFO) technology, Solstice zd and Solstice ze are non-ozone-depleting

Solstice N15:

  • A nonflammable azeotropic blend designed for chillers, heat pumps and high-ambient air conditioning systems.
  • GWP of 293, demonstrates environmental and performance benefits in new systems whilst its similar product design to R1234ze provides a long-term solution that is suitable for both A1 and A2L refrigerants

Solstice 454B (R-454B):

  • A non-ozone depleting, zeotropic blend designed to serve as a lower GWP alternative to R-410A in reversible chillers and heat pump applications
  • Improved efficiency and matching capacity to R-410A, that enables OEMs to transition their R-410A equipment to a lower GWP alternative conveniently

Solstice N13

  • Zeotropic blend of R-134a and HFO-1234ze designed to serve as a nonflammable alternative to R-134a in medium temperature systems, offering similar performance and energy efficiency but with a 60% lesser GWP
