Transport cooling systems ensure that frozen or chilled food remains at the correct temperature at all times. They keep the cold chain intact – from manufacturer to consumer, in line with statutory regulations and Hazard Analysis Critical Control Point (HACCP) concepts.
Cryogenic gas-based cooling systems are primarily used to transport products from a wholesaler’s central warehouse to a sales outlet, or from a catering kitchen to an event venue. They require no electrical connections or diesel units, run quietly and release few emissions. In addition, they offer effective and rapid cooling power, especially when doors are opened frequently, and they support different temperature zones.
We offer tailor-made solutions based on three different transport systems:
1. Container cooling
Container cooling uses various cryogenic agents to cool insulated containers:
Dry ice has a temperature of –78 °C. The cold is released through sublimation. Dry ice is flexible, easy to use and available in slabs of different sizes (0.6–10 kg).
Dry ice snow (SNOWCOOL®) also cools via sublimation. Dry ice snow is produced in an isotainer by feeding liquid carbon dioxide into a built-in snow box. The quantity of snow produced can be adapted to the products being transported.
Suitable for:
Direct delivery (drop shipping)
Various temperature zones
Variable volumes for different temperature zones
Journeys with numerous stops or where the door is opened frequently.
2. Vehicle cooling
Vehicle cooling involves cooling the entire vehicle body. There are two main cryogenic systems here. One system cools the vehicle indirectly using CO2 while the other involves directly or indirectly cooling vehicles with nitrogen.
Suitable for:
Large volumes requiring the same temperature
Long distances
Journeys where the door is opened less frequently
Specialised logistics systems.
3. Package cooling (shipping prototypes and samples)
Dry ice can also be used to cool smaller shipping units such as packages or boxes in the form of cool bag sheets or nuggets. The amount of dry ice can be measured exactly to achieve the temperature required for both deep-freeze and above-zero shipping. Dry ice package cooling is ideal for cooling foodstuffs such as seafood products, cheese and cooked meats, animal feed and samples for three days or more (for intercontinental shipping).
In cases where smaller quantities or only a few samples are to be shipped, dry ice (ICEBITZZZ®) can also be supplied in polystyrene boxes by express courier (6–25 kg dry ice/package). It can also be ordered in small quantities under agreement for regular package shipments.
