APRU 6L Autonomous Portable Refrigeration Unit
The Autonomous Portable Refrigeration Unit (APRU) is an FDA-registered and CE-certified device that provides constant cooling for blood products, vaccines, and temperature-sensitive medications, using a standard military battery with a 95-hour operating time. The APRU, also known as “The Delta,” features intuitive on-screen controls and records stored temperature for up to 72 days. Thanks to its heating and cooling capabilities, it maintains stable temperatures in all challenging environments, ranging from military operations and disaster response to emergency medical systems.
The APRU 6L is the new standard for mobile medical refrigeration in extreme conditions. The system is designed for military units and medical teams that depend on absolute reliability during high-risk missions, limited evacuation opportunities, and prolonged evacuation times. The APRU 6L delivers dependable medical cooling for the most demanding operations.

For Special Forces & missions with extended evacuation times
Special Forces often operate outside conventional logistical chains, in environments where temperature control has a direct impact on survival. The APRU 6L ensures:
- 95 hours of autonomous cooling on a single military battery
- A stable temperature of 4.5°C ± 0.8°C, regardless of climate or orientation
- A robust construction resistant to shock, vibration, rain, dust, and saltwater
- 99.9% reliability through advanced dual-mode heating and cooling
The result: temperature-sensitive blood products and medication remain usable even during prolonged infiltrations, deep-reconnaissance operations, or when CASEVAC is not immediately possible.
Indispensable for Special Operations Surgical Teams (SOST)
For medical teams performing life-saving interventions under high pressure, maintaining control over temperature-sensitive medication is essential. The APRU 6L supports SOST teams by:
- Safe transport and storage of blood products (500 ml × 6 units)
- Reliable temperature recording for 72 days
- Intuitive operation with clear on-screen prompts
- FAA/HAA qualification for deployment during air transport and MEDEVAC
This makes the APRU 6L a proven solution that directly contributes to successful damage control resuscitation during austere operations.
Ideal for deployment in disaster zones and humanitarian missions
During natural disasters, large-scale incidents, or conflict zones, a stable temperature supply is often not guaranteed. The APRU 6L operates completely independent of local infrastructure and offers:
- Immediately deployable cooling without an external power source
- Stable performance in temperatures from −32°C to +50°C
- Water and dust resistance according to IP66 / NEMA4X
- Easy implementation by aid organisations and medical teams
Whether it involves transporting blood, vaccines, antivenom, antibiotics, or any temperature-critical medication — the APRU 6L keeps it safe, stable, and life-saving.
