Natural Coolant for the Reefer-containers

As per announcement by Carrier Transicold, industry has recently got CO2 as the new "environment-friendlier" refrigerant to be used in the reefer-container temperature control systems. It is not about the natural CO2-based refrigerant medium R-744, but also about the new refrigeration-unit design.

Benefits of R-744 are:

• non-ozone depleting medium
• global warming potential (GWP) of 1 score, while the synthetic coolant R134a has GWP of 1320, R404a - of 3260
• CO2 used is the gas retrieved from the atmosphere, thus not adding to the environmental hazards if leaked out

New unit design allows for:

• more efficient heat transfer
• power efficient inverter-type fan and compressor control

Carrier Transicold, a company pioneering the technology, is shortly launching the full scale trials of the systems.
