Medical transport: Reliable cooling for temperature-critical goods

Cooling packs form the backbone of passive cold chains. Their reliable conditioning to defined target temperatures is essential for product quality and regulatory compliance.

The AIRFROSTER® conditions cooling packs reproducibly and in a validated manner – for the safe and sustainable transport of pharmaceuticals, blood products, vaccines, and biological samples.

For GDP-regulated applications, the AIRFROSTER® supports the reproducible implementation of temperature-controlled processes as well as documentation requirements in accordance with the Good Distribution Practice guidelines.

The challenge

Different temperature ranges, highest requirements

Depending on the goods being transported, specific temperature requirements apply – from refrigerated products (+2 to +8 °C) to deep-frozen goods (−20 °C or lower).
These requirements pose major challenges for transport companies, clinics, and laboratories:

Different temperature ranges must be managed simultaneously,
the cold chain must be fully documented, and
processes must be validated and reproducible.

The result: Process reliability, energy efficiency, and sustainability are difficult to achieve with conventional solutions.

Challenges of conventional cooling in medical transport

Uneven temperature distribution

Standard cooling units without dedicated cooling programs create inhomogeneous temperature profiles. The result is varying final temperatures of the cooling packs.
Lack of process reliability

Without validated cooling programs, reproducible conditioning to defined target temperatures cannot be ensured.
Trade-off: energy efficiency vs. process reliability

Conventional solutions require significantly undershooting the target temperature to safeguard the process – resulting in increased energy consumption.
High operating costs

The use of dry ice leads to considerable procurement and storage costs and involves significant handling risks.
Environmental impact

Dry ice releases CO₂ during use and has a lasting negative impact on the environment.

The solution

AIRFROSTER®: Two cooling chambers, precise temperature control, validated processes

The AIRFROSTER® features two independently controllable cooling chambers for the parallel conditioning of cooling packs to different target temperatures – validated, reproducible, and with complete temperature documentation up to the point of pack removal.

This ensures perfect passive cooling for the last mile and guarantees that recorded temperature values are accurate and reliable. All without compromising efficiency or sustainability: as an alternative to dry ice, the AIRFROSTER® reduces CO₂ emissions by around 90% – GDP compliance and environmental responsibility are not mutually exclusive, but complementary.

Two independent cooling chambers

Parallel conditioning of cooling packs to different target temperatures (e.g. +5 °C and −20 °C) – two temperature ranges, one system.

Precise temperature control

Adjustable target temperature range from −35 °C to +15 °C. Uniform pack temperature at removal ensures reproducible conditioning and minimizes the risk of temperature fluctuations during transport.

Validated cooling performance & process reliability

Includes documented process qualification for quality management – carried out as a real-world test prior to commissioning. Continuous monitoring, programmable control with time stamps, and complete documentation ensure audit-ready validation.

Energy-efficient & sustainable

Precise conditioning to the target temperature eliminates energy-intensive overcooling. Reusable cooling packs replace dry ice – reducing CO₂ emissions by up to 90% in comparison.

Ergonomic & user-safe

Magnetically locking pack basket trolley enables low-effort loading and unloading. 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 long-term operational reliability and minimize downtime.

Temperature-controlled transport of blood products

Blood units and plasma products require a continuous temperature range of +2 °C to +8 °C during transport. The AIRFROSTER® conditions cooling packs in a validated manner to the defined target temperature – regardless of external conditions.

Temperature-controlled transport for laboratory samples

Biological samples, tissue samples, and diagnostic materials are subject to specific temperature requirements. The two independent cooling chambers of the AIRFROSTER® enable parallel conditioning for different sample materials with varying target temperatures.

Safe vaccine logistics

Vaccines require different temperature ranges depending on the product type – from +2 °C to +8 °C for standard vaccines to −20 °C or lower for mRNA vaccines. The two independent cooling chambers of the AIRFROSTER® allow parallel preparation of cooling packs for different temperature requirements.

Validated cold chains for temperature-critical medical goods

Blood products, biological samples, and vaccines require seamless, documented temperature control throughout the entire transport process.

The AIRFROSTER® ensures process-reliable conditioning of cooling packs for passive cold chains in medical transport.

✓ Validated temperature control
✓ Quality management documentation included
✓ Reproducible conditioning
✓ Risk minimization for temperature-critical transports
