Two kinds of transport are involved:

  • Marine container
  • Truck and trailer

In these refrigerated systems, the main challenge is the units' large operational envelope. The required temperature is normally between +7 °C and -24 °C. Applications identified for our products are:

  • Economizer
  • Suction gas heat exchanger

The reason for installing these BPHEs is related to the increased system efficiency that can be achieved with these additional features – an increase that justifies the increased circuit complexity. The refrigerants involved are R134a and R404A. Interesting case studies and prototypes are currently ongoing using CO2 to substitute synthetic refrigerants. In these cases, a transcritical cycle is considered.
