Carrier offers R513A for PrimeLINE

Carrier's PrimLINE reefer unit
Carrier Transicold has provided further details on its move to offer the R513A refrigerant as a drop-in replacement for R134a.

This was first announced at the Intermodal Europe exhibition in Amsterdam in November, and covered in a report in the December 2017 issue of WorldCargo News. At the time Willy Yeo, director of marketing, Global Container Refrigeration, Carrier Transicold, said while Carrier will offer R513A as a drop in replacement for R134a, it can cost as much as four times the price currently.

Carrier Transicold has now clarified that it is “offering a provision to use R-513A refrigerant with its PrimeLINE container unit for customers seeking a refrigerant with lower global warming potential (GWP), or as a hedge against potential regulatory changes that may affect the availability and prices of traditional hydrofluorocarbon (HFC) refrigerants”.

“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 Yeo.

R-513A, a new synthetic blend of the hydrofluoroolefin R-1234yf and R-134a, has a GWP of 631, compared to a GWP of 1360 for R134a.

New PrimeLINE refrigeration units from Carrier Transicold have a “513A-ready” provision. “It features 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 own choosing. Conversions require a simple kit that includes a software update and replacement filter dryer,” Carrier explained.

Carrier anticipates that the 513A-ready PrimeLINE unit will be available in Q1 of this year, with conversion kits ready later in the year.

While offering R513A, Carrier is also trying to nudge customers towards its NaturaLINE reefer unit, which is still the only commercially available reefer unit to use the natural refrigerant CO2. “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 uses carbon dioxide, an ultra-low GWP refrigerant.”

Carrier claims the NaturaLINE unit’s combination of efficiency and use of an ultra-low GWP refrigerant reduces carbon emissions by 28% percent compared to “earlier models”. The economic incentive to switch is also growing: the longer reefer owners leave the transition the greater the risk of stranded assets. “With a GWP of 1, CO2 refrigerant takes refrigerated container customers 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 purchased today,” Carrier concluded.
