CRT has been involved in the use of cryogenics and eutectics since the early 1970’s for refrigerated transport.
Cryogenics for refrigerated transport is the use of liquid nitrogen or liquid/solid carbon dioxide for maintaining or cooling down perishable products by using the phase change to absorb heat.
A eutectic or eutectic mixture is a mixture of two or more phases for example ice and water at a composition that has the lowest melting point, and where the phases simultaneously crystallise from molten solution at that temperature. The ratio of phases to obtain a eutectic is identified by the eutectic point on a phase diagram.

Eutectics are used in transportation for applications such as air transport and sometimes to provide a cold sink when very high refrigeration loads are experienced for short periods of time.
Projects in which CRT have been involved:
-
Snow shooting (solid CO2 injection) of insulated containers of meat
-
Liquid nitrogen cooling of containers
-
Testing of a liquid nitrogen tower system
-
Testing of a combination mechanical refrigeration and liquid nitrogen injection system
-
Airfreight packaging systems utilising eutectics
-
Cooling of airfreight containers with dry ice (solid CO2 )
-
Development of a liquid nitrogen road transport system
-
Testing of cryogenically cooled vaccine cabinets
-
Testing multi-drop small vans utilising eutectics
