Product will mark second special store test of a lower GWP, lower flammability refrigerant to determine best practice for possible wider roll out nationally
A lower flammability refrigerant with a GWP of 146 developed by Honeywell has been selected by Central England Co-operative for a trial at a community food store in Tamworth.
The company said its Solstice L40X product, R445A, has been selected for use in one of only two of the retailer’s UK-based stores to fully use A2L products as part of a live test. A2L systems and products require specific installation maintenance due to having some form of flammability, albeit it at a lower level.
Kevin Collins, head of facilities and technical services with Central England Co-operative, said that the retailer’s experience of installing and using the refrigerant at its Tamworth site would be used to ensure best practice for future store openings.
He said, “Solstice L40X offered exactly what we were looking for in a refrigerant: low GWP, simplicity, no new or specific training for our maintenance teams, and with system footprint and CAPEX equivalent to R404A.”
Honeywell claimed that L40X was designed as a replacement for R404A and would ensure a long-term, safe and energy efficient refrigerant that met the requirements of both F-Gas regulation and the EN378 standard.
Honeywell has worked with Carter Synergy, Space Engineering and Zanotti on the project.
Central England Co-operative last year partnered with Chemours on a live trial of the very-low-GWP HFO, R454C, at a convenience store at Langley Park, Derbyshire.
The retailer has previously committed to a robust 10-year F-Gas strategy, building on its experience retrofitting existing R404A systems to mid-range HFO blends (<1500 GWP). The retailer noted last year that it was more ‘comfortable with the operating characteristics of these systems and has seen the energy-efficiency gains from these retrofits.
