CARRIER'S Transicold transport refrigeration business has come up with a system to use CO2 in container refrigeration systems.
The NaturaLine system is said to have already been tested around the world this year by Hamburg-based Hapag-Lloyd. Carrier will conduct full field trials in 2011.

Carrier's technology is said to incorporate numerous innovations, some of which are new to container refrigeration applications. These include a new gas cooler/condenser coil that wraps around the fan and has enhanced surfaces to maximise heat transfer. It also takes advantage of a new marine-duty multi-stage compressor. New power electronics and an advanced software control system are said to be combined to optimize fan speeds and compressor capacity to match cooling loads and temperature control.
