Service of mobile refrigeration systems with CO₂ (R744) – reliability on the move

With the growing focus on environmentally friendly solutions , the natural refrigerant R744 (CO₂) is increasingly used in mobile refrigeration systems – from refrigerated trucks and trailers to sea containers and air-conditioned buses. These systems offer not only high energy efficiency , but also minimal environmental impact , as CO₂ has zero ozone depletion potential (ODP = 0) and low greenhouse gas emissions (GWP ≈ 1) .

Types of CO₂ mobile refrigeration systems

1. Subcritical CO₂ systems:
   Work effectively at moderate temperatures
   Suitable for sea containers , refrigerated trailers , food and medicine transportation
   
   
2. Transcritical CO₂ systems:
   Optimized for operation in warm climates
   Often used in buses with air conditioning , urban deliveries , long international transport
