Carrier Transicold’s NaturaLINE®


NaturaLINE® is the world’s first natural refrigerant technology for container refrigeration. The NaturaLINE unit incorporates carbon dioxide (CO2) in place of conventional synthetic refrigerants to deliver best-in-class sustainability and efficiency.


We’ve Created The Future of Container Refrigeration. Naturally.

Carrier has been a pioneer in sustainability from the very beginning. By developing NaturaLINE to address the industry’s ongoing concerns about sustainability and the environment, Carrier is building on that legacy.

For container shipping, CO2 is the only refrigerant that meets all of the following criteria:

  • Global warming potential (GWP) of 1
  • Zero ozone depletion potential (ODP)
  • Excellent heat transfer/heat reclaim properties
  • Non-flammable
  • Cost-effective, available worldwide and requires no special disposal

The use of CO2 makes NaturaLINE the clear choice for the shipping industry. NaturaLINE improves upon the ability of Transicold’s PrimeLINE® unit to reduce carbon emissions by 28 percent compared to previous units, while matching its best-in-class energy efficiency.

The NaturaLINE unit includes a number of patented “firsts” for container refrigeration applications, including a multi-stage compressor, variable-speed drive, gas cooler coil, flash tank, two-speed fans, advanced operating software and zero-GWP foam insulation.

Well ahead of any potential regulations, NaturaLINE technology responds to customer concerns about GWP. It’s just one more example of Carrier’s ongoing commitment to developing new technology that minimizes environmental impact while serving customer needs. And that’s what natural leadership is all about.
