Commercial refrigeration: marketing of R471A, a new alternative to R404A
Honeywell recently announced the marketing of R471A, a non-flammable refrigerant with a GWP under 150. It is expected to replace R404A in medium temperature commercial refrigeration...
US: a step closer to authorizing HCs in vending machines?
A submission by A.S. Trust & Holdings requesting SNAP approval for the use of hydrocarbon refrigerant R441A in new vending machines has been found complete by the US Environmental Protection Agency (EPA). As a result, “R441A may be sold in new...
