Lower GWP Refrigerant Option Available for PrimeLINE ® Container Units Still, based on customer feedback, Carrier Transicold understands that some operators have come to rely on the R-134a-based PrimeLINE ® refrigeration unit and are not ready to transition to a new model. For those acquiring new PrimeLINE refrigeration units who are concerned about GWP or want to hedge against potential regulatory changes that may affect the availability and prices of traditional hydrofluorocarbon (HFC) refrigerants, Carrier Transicold is now offering a provision to use R-513A refrigerant. "Phasedowns of traditional HFC refrigerants due to their higher GWP have raised concerns about their future availability and pricing, and some of our customers have indicated an interest in using R-513A as an alternative," said Willy Yeo, director of marketing, Global Container Refrigeration, Carrier Transicold. R-513A is a new synthetic blend of the hydrofluoroolefin R-1234yf and R-134a. It has a GWP of 631, which is significantly lower than those of HFC refrigerants conventionally used in container refrigeration systems. PrimeLINE units with the "513A-ready" provision have a new digital scroll compressor designed for use with R-513A, as well as traditional R-134a. The units will be sold with R-134a, enabling customers to switch to R-513A at a time of their choosing. Conversions require a simple kit that includes a software update and replacement filter dryer. "Fleets that want to use a more sustainable refrigerant and also want to hedge against price and availability issues associated with synthetic refrigerants should first consider Carrier Transicold's natural-refrigerant NaturaLINE unit," Yeo said. "The NaturaLINE unit offers efficiency, quiet operation, tight temperature control, a deep frozen capability that goes to -40 degrees Celsius, and an ultra-low GWP natural refrigerant. "With its GWP of 1, CO 2 refrigerant takes refrigerated container customers directly to an end state, bypassing the need for intermediate solutions such as R-513A, which will be subject to phase-outs within the 15-year lifespan of units," Yeo said. "As we've consistently stated, natural refrigerants represent a long- term end state, and forward-thinking shipping lines will want to start now to transition to natural-refrigerant-based container refrigeration systems." The 513A-ready PrimeLINE unit is available now, and conversion kits will be available later this year.

The NaturaLINE unit's performance is exceptional, and no one offers a container refrigeration system using a refrigerant with a GWP lower than the NaturaLINE unit's carbon dioxide (CO 2). PrimeLINE units are now available with a provision allowing future conversion from R-134a to the lower GWP refrigerant R-513A. 4
