Air Conditioning, Refrigeration and Heating

Honeywell Refrigerants support industries such as supermarkets, cold storage facilities, ice rinks and residential air conditioners, while Honeywell Heating products support heat pumps, chillers, vending machines, cascade systems and more. What they share in common is Honeywell's groundbreaking technology that combines greatly reduced GWP and operational safety to reduce these industries’ carbon footprint, improve their performance, and comply with regulations.

In anticipation of the latest regulatory transitions, Honeywell Refrigerants introduced Solstice N71, a next-generation solution for commercial refrigeration applications such as supermarkets, while Solstice N41 offers a 65% lower GWP for stationary residential and commercial air conditioning systems. Honeywell Genetron is an HFC alternative to CFCs and HCFCs.

From Honeywell’s Heating business comes the zeotropic blends of Solstice L40X (R-455A), an ultra-low GWP for low-, medium- and high-temperature applications in new systems; the non-ozone depleting Solstice® 454B (R-454B) as an alternative to R-410A in comfort air cooling and reversible heating applications; and the R-134a / HFO-1234ze (Solstice® ze) blend, Solstice N13 (R-450A), for similar performance to R-123a with 60% less GWP.

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. 

Featured applications

Solstice and 245fa non-ozone-depleting insulation for commercial and residential applications

Supermarket Refrigeration

More than 60,000 supermarkets globally, trust Solstice Refrigerants to help them comply with current and proposed regulations, with the aim of reducing the use of high-GWP HFCs. No matter what your store footprint is – small, medium, or large, our Solstice technology offers you refrigerant for low and medium applications for new systems and retrofits. 

4 reasons to choose Solstice N41 for your next refrigeration system 

Solstice N71 (R-471A)

  • Honeywell’s newest non-ozone depleting, non-flammable, HFO based refrigerant with <150 GWP, for new equipment in medium temperature applications.
  • Provides energy efficiency improvement* of 30% compared to CO2 and 13% versus R-404A, helping supermarkets reduce their overall CO2 footprint (Scope 1 and Scope 2 emissions)

Solstice L40X (R-455A)

  • Energy efficient, low GWP of 146, mildly flammable zeotropic blend that serves as an alternative for low, medium and high temperature applications in new systems
  • Close capacity match to R-404A 

Solstice® N40 (R-448A)

  • Lower-GWP non-flammable refrigerant for low and medium temperature supermarket refrigeration retrofits and new systems
  • Demonstrates lower energy consumption, increased refrigeration capacity and coefficient of performance (COP) compared to R404A

Cold Storage

Consistent cold storage with low-GWP refrigerants is critical for food safety and vaccine delivery. Shifts in the supply chain because of the global pandemic has changed the need for refrigerated warehouses. Honeywell Solstice® refrigerants, with low- and reduced-GWPs help environmentally conscious cold storage operators comply with requirements during a time of increased global demand.

Solstice L40X (R-455A)

  • Energy efficient, low GWP of 146, mildly flammable zeotropic blend that serves as an alternative for low, medium and high temperature applications in new systems
  • Close capacity match to R-404A

Solstice N71 (R-471A)

  • Honeywell’s newest non-ozone depleting, non-flammable, HFO based refrigerant with <150 GWP, for new equipment in medium temperature applications.
  • Provides energy efficiency improvement* of 30% compared to CO2 and 13% versus R-404A, helping supermarkets reduce their overall CO2 footprint (Scope 1 and Scope 2 emissions)

Solstice N40 (R-448A)

  • Lower-GWP non-flammable refrigerant for low and medium temperature supermarket refrigeration retrofits and new systems
  • Demonstrates lower energy consumption, increased refrigeration capacity and coefficient of performance (COP) compared to R404A

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

Comfort Cooling Air Conditioning

R-410A is one of the most widely used refrigerants around the world for residential and light commercial air conditioning applications. To comply with critical regulatory phasedowns of high-GWP products, R-410A must be replaced with a safe, energy-efficient, lower-GWP solution with similar or better performance.

Solstice 454-B

  • Demonstrates improved efficiency and matching capacity to R-410A, with a GWP that’s 78% lower
