Biobanking where the grid is unreliable
Field stations, research vessels and rural collection sites rarely enjoy stable mains power. A portable −86 °C freezer that also runs on 24 V DC lets a biobank operate from solar-buffered batteries, a vehicle, or a generator without a fragile AC inverter chain.
Designing a resilient field freezer setup
- Size to your cadence. The 13 L unit is enough for daily collection; larger 45 L banks suit weekly courier pickups.
- Minimise lid openings. Stage samples and batch them to protect the cold sink.
- Secure the chain of custody. A lockable lid and logged temperature record matter as much as the cooling itself.
Why Stirling for the field
With no oil in the cold head and only 120–280 W draw, the free-piston Stirling engine tolerates tilt, transport and intermittent power far better than a traditional compressor. That is why we see it adopted for remote biobanking and expedition research.
