Carrier offers natural refrigerant for containers

Carrier offers natural refrigerant for containers    Carrier Transicold said Tuesday it has introduced a new container refrigeration technology that uses natural refrigerant.
   The company's NaturaLINE unit relies on carbon dioxide instead of conventional synthetic hydrofluorocarbon refrigerants, which have higher global warming potential.
   Carrier said it has already placed demonstration units in service for around-the-world tests with Hamburg, Germany-based Hapag-Lloyd. In 2011, it will extend the program with full field trials.
