R-410a
A key deadline for phasing out hydrochlorofluorocarbons (HCFCs) from residential air conditioning systems is less than a year away. Jan. 1, 2020, is the deadline after which there will be no U.S. production or import of HCFC-142b and HCFC-22 (also called R-22). The deadline is part of an incremental phazeout of HCFC consumption and production based on the U.S. commitment in the 1997 Montreal Protocol aimed at protecting stratospheric ozone. Section 605 of the Clean Air Act establishes phazeout...
Carrier confirms its refrigerant strategy in Europe by choosing HFO refrigerants with low Global Warming Potential (GWP) for most of its commercial heating, ventilating and air conditioning (HVAC) product applications. Carrier, a world leader in high-technology heating, air-conditioning and refrigeration solutions, is a part of Carrier, a leading global provider of innovative HVAC, refrigeration, fire, security and building automation technologies. Carrier is committed to delivering solutions t...
Keeping with its long history of sustained environmental responsibility, Carrier has once again taken a pivotal role in offering the refrigerant of the future. After extensive tests and evaluation, Carrier has identified R-454B, to be known commercially as Puron Advance, as its primary lower Global Warming Potential (GWP) solution to replace R-410A in all of its ducted residential and light commercial packaged solutions sold in North America. R-454B Puron Advance refrigerant Carrier will sele...

MSC Mediterranean Shipping Company, global provider of transportation and logistical solutions, is expanding its fleet with a record-setting order of 5,000 refrigerated containers equipped with Carrier Transicold’s XtendFRESH atmosphere control technology, as part of a larger order. This innovative system manages oxygen and carbon dioxide levels within refrigerated containers and removes ethylene, thus slowing the ripening of produce and helping to preserve its quality beyond what can be achieved by refrigeration alone. XtendFRESH-equipped containers The XtendFRESH-equipped containers are being leased through SeaCube Containers LLC The XtendFRESH-equipped containers are being leased through SeaCube Containers LLC. Carrier Transicold is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. “By adding atmosphere control for selected perishable cargoes, we are enhancing the care we provide for the valuable commodities we ship for our customers,” said Giuseppe Prudente, chief logistics officer, MSC Mediterranean Shipping Company. “XtendFRESH technology enables MSC to transport fruit and other refrigerated cargo over longer distances, creating tremendous new opportunities for exporters and importers.” Controlled-atmosphere equipment MSC’s order is the largest for the XtendFRESH option since the system was introduced in 2013, and it represents a significant step in the growing trend among shipping lines to provide controlled-atmosphere technology for the benefit of their customers, according to Willy Yeo, Director of Marketing, Global Container Refrigeration, Carrier Transicold. SeaCube CEO Robert Sappio agrees that factors such as slow steaming and new trade routes, resulting from shipping line alliances and consolidations, are creating opportunities for XtendFRESH technology. “MSC is just one example of the very strong demand we’ve seen for controlled-atmosphere equipment. As shipping lines fine-tune their operations and optimize their networks, controlled atmosphere is a way for them to assure their customers that they are carrying their products more safely.” Fresh-air ventilation In use, the XtendFRESH system’s patented, self-regenerating activated-carbon scrubber assembly captures carbon dioxide and ethylene, a hormone given off by ripening produce that can accelerate ripening if left unchecked. As perishable cargo consumes oxygen, on-demand fresh-air ventilation automatically maintains the optimum level inside the container. “The innovative XtendFRESH system allows shipping lines to optimize conditions for specific commodities,” Carrier Transicold’s Yeo said. “It is the only atmosphere control solution with an integrated ethylene removal capability.” PrimeLINE refrigeration units PrimeLINE units use digital scroll compressors to deliver greater cooling capacity using less energy The XtendFRESH system was selected by MSC as an option for Carrier Transicold PrimeLINE refrigeration units being installed on new 40-foot high-cube containers. In support of its environmental initiatives, MSC specified PrimeLINE units with a new provision that enables conversion from R-134a to R-513A, a refrigerant with a significantly lower global warming potential. PrimeLINE units use digital scroll compressors to deliver greater cooling capacity using less energy than prior models from Carrier Transicold. The PrimeLINE unit’s value proposition also includes rapid pull-down, tight temperature control, high air-flow performance and excellent cost of ownership. Global shipping company With global headquarters in Geneva, Switzerland, MSC Mediterranean Shipping Company S.A. is a privately owned global shipping company with vessels that sail on more than 200 trade routes, calling at over 500 ports, with access to an integrated network of road, rail and sea transport resources that stretches across the globe.
