AIRFROSTER® for food transport
HACCP-compliant adherence to the cold chain is a regulatory requirement for delivery services, catering companies, and in-house meal supply in hospitals. The AIRFROSTER® conditions cooling packs to defined target temperatures – reproducible, validated, and fully documented.

HACCP-compliant cold chains
Over 95 years of cooling expertise
Ensuring HACCP-compliant cold chains in food transport
Delivery services, catering companies, and hospitals with in-house meal supply are required to maintain food within defined temperature limits throughout the entire transport process. HACCP guidelines demand continuous temperature control, complete documentation, and verifiable processes.
Particularly critical: Cold meals in hospitals and care facilities must not exceed +7 °C. Between central preparation and distribution on wards, relevant time windows arise in which reliable passive cooling must ensure compliance with temperature limits.
The challenge
Why precise cooling is critical is
Breaks in the cold chain account for around 13% of global food waste each year in the food wholesale sector. At the level of wholesale and retail, as well as large-scale consumers – including gastronomy and canteens – avoidable food waste amounts to nearly 6 million tonnes annually, with a reduction potential of 70% to 90%.
Key risks on the last mile
The final stage of transport from warehouse or restaurant to the end customer places the highest demands on cold chain compliance. The following risk factors are particularly critical:
-
Time variability and ambient temperatures
High ambient temperatures and operational bottlenecks extend unloading times. Due to time pressure, different temperature ranges are often transported within the same unit.
-
Process complexity and limited monitoring
Changing transport modes and delivery methods make it challenging to keep cooling pack temperatures consistently low throughout the entire delivery process and to reliably meet regulatory requirements. Compared to centralized cold storage, options for active temperature control on the last mile are limited.
The solution
AIRFROSTER®: Two cooling chambers, precise temperature control, HACCP-compliant processes
The AIRFROSTER® is specifically designed to meet the requirements of HACCP-compliant food logistics. With its two independently controllable cooling chambers, cooling packs can be conditioned in parallel to different target temperatures – validated, reproducible, and with complete temperature documentation up to the point of pack removal. This enables operators to comply with required cold chain standards accurately and verifiably.
As a sustainable alternative to dry ice, the AIRFROSTER® reduces CO₂ emissions by around 90% while ensuring process-reliable cold chains.
Two independent cooling chambers
Parallel conditioning of cooling packs to different target temperatures – enabling the simultaneous transport of chilled and frozen food products within a single system.
Precise temperature control
Adjustable target temperature range from −35 °C to +15 °C – covering requirements from the +7 °C limit for cold meals to deep-frozen products. Uniform pack temperature at removal minimizes temperature fluctuations during delivery.
HACCP-compliant documentation
Includes documented process qualification for the QM system – carried out as a real-world test using the customer’s own cooling packs prior to commissioning. Continuous monitoring, programmable control with time stamps, and complete documentation ensure full traceability in accordance with HACCP guidelines.
Sustainable alternative to dry ice
Reusable cooling packs fully replace dry ice – reducing CO₂ emissions by up to 90% in comparison. Precise conditioning to target temperature eliminates energy-intensive overcooling.
Ergonomic & user-safe
Magnetically locking pack basket trolley enables low-effort loading and unloading in daily delivery operations. A 4.3-inch LCD touchscreen with intuitive controls minimizes user errors.
Plug-and-play system
Integrated solution consisting of shock freezer, pack basket, and transport trolley. Operates on 230 V – no installation required, ready for immediate use.
Remote maintenance & full service
Ongoing device data available online, with remote troubleshooting in case of issues. Optional full-service contracts ensure continuous operational readiness for delivery services and catering businesses.
HACCP-compliant cold chains for safe food transport
Delivery services, catering companies, and in-house meal supply are subject to HACCP requirements for temperature control, documentation, and process reliability – while at the same time facing increasing pressure to design cooling processes in an energy-efficient and sustainable way. The AIRFROSTER® meets both requirements.
The AIRFROSTER® ensures process-reliable conditioning of cooling packs for HACCP-compliant passive cold chains in food transport.
