Try Solstice® Refrigerants For Your New Systems

Supermarkets are invited to sign up for our “Transition to a lower-carbon future" program. This program is designed exclusively for environmentally conscious supermarkets to try Solstice® L40X or Solstice® 454C in an installation of new refrigeration equipment. Once you sign up for this program, our team of experts will work closely with you to implement Solstice® refrigerant in your new refrigeration system and help you meet your sustainability goals.

As carbon emission regulations become more stringent on the use of high-GWP HFC (hydrofluorocarbon) refrigerants, more grocery and convenience stores are opting to replace their legacy refrigerants with lower-GWP solutions like Honeywell Solstice® L40X (R-455A) and Solstice® 454C (R-454C).

Compared to CO₂ and Propane, Solstice® refrigerants deliver*:

Solstice® A2L Benefits

Reduce CO₂ footprint

Solstice® L40X and Solstice® 454C are mildly flammable (A2L), <150 GWP refrigerants that provide energy efficiency improvement over CO₂, helping supermarkets reduce overall CO₂ footprint (Scope 1 and Scope 2 emissions).

Minimum system redesign

Unlike CO₂ refrigeration systems, Solstice® refrigerants have a lower CAPEX requirement because of an easy conversion with minimal changes from the previous system.

Easy installation and maintenance

In contrast to CO₂ based systems, which demand specialized skills and capabilities, Solstice® L40X and Solstice® 454C systems follow standard installation and maintenance practices, requiring no elite skillset and experience.

Choosing The Right Refrigerant For Your Supermarket, And It's Not CO₂

CO₂, a supposedly “natural” refrigerant that despite having low GWP, falls short on several other factors that are important to supermarkets. It's time to reassess CO₂-based systems and consider a transition to clean, low GWP, HFO-based refrigerants.

Customer Success Stories

Honeywell A2L refrigerants for supermarkets - image of refrigerant aisle in a supermarket

Edeka — Erxleben, Germany

Installed Solstice® L40X in November 2020

30% savings on electricity and heating costs compared to central refrigeration systems
40% lower energy consumption than plugin refrigeration units without heat recovery
35% lower investment costs than a comparable CO₂ system

“Our hybrid system, in conjunction with Honeywell Solstice L40X, demonstrates that it’s possible to implement a refrigeration system that minimizes investment, operating and maintenance costs while also meeting an operator’s climate goals. We’re proud that this collaboration has resulted in a sustainability milestone for KONSUM and Edeka.”

Goran Simic, KMW Sales and Service Director

MD Discount Store— Persiceto, Italy

Installed Solstice® L40X in January 2023

25% lower lifetime emissions projected compared to CO₂ systems
Projected savings of €260,000 in lifetime cost compared to CO₂systems*

“We are now engaging with Honeywell to further our work in this area and implement Solstice L40X in our new San Giovanni in Persiceto store, which is projected to support a lifetime cost savings of approximately €260,000 and 25% lower lifetime emissions compared with carbon dioxide for that store alone.”

Michele Aiello, Technical Director, MD

*Based on data input from MD and specific analyses using Honeywell’s Eco-Efficiency model.

* Based on ORNL report - Technology Options for Low Environmental Impact Air-Conditioning and Refrigeration Systems, for efficiency evaluated at typical design condition (95°F). The COP for
Solstice 454C, Solstice L40X, R-290 and CO₂ are 1.99, 2.05, 1.62 and 1.17 respectively at ambient temperature of 95°F. The report also provides LCCP analysis for Atlanta (Emission Factor = 0.497
kgCO₂/kWhr) for Solstice 454C, Solstice L40X, R-290 and CO₂, which are 7269901 kgCO2e, 7158019 kgCO₂e, 8444764 kgCO₂e and 8853301 kgCO₂e respectively as total emissions which is
the sum of direct and indirect emissions. For details, please visit OSTI.GOV
Unlike CO₂ refrigeration systems, Solstice® refrigerants have a lower CAPEX requirement. Being a high-pressure refrigerant, CO₂ systems need entirely new equipment and
costly components to withstand high pressure conditions.
