What Is a Solar Refrigerator-Freezer Used For?
Immunisation outreach depends on two things at the base clinic: a cold, safe store for vaccines and a steady supply of frozen water packs to keep cold boxes and vaccine carriers cool on the road. This appliance provides both from one solar-powered unit. The refrigerator section keeps 36 litres of vaccine, while the freezer section freezes water packs at 1.8 kg per day and holds a stock of 29 packs of 0.6 L ready for the next session.
Plan freezing a day or more ahead of outreach, rotate packs so the oldest frozen ones are used first, and condition frozen packs according to your programme's cold-chain guidelines before packing vaccines that must not freeze. Keep the unit in a shaded room within +5°C to +43°C. For clinics that cannot justify two separate appliances, it replaces a stand-alone laboratory refrigerator and freezer pair with one off-grid unit.
What to Specify When Ordering
- The number of units and the sites where they will be installed.
- How many 0.6 L water packs you need in addition to the unit's own storage.
- Site room temperatures and solar conditions, compared with the +5°C to +43°C range and the 3.5 kWh/m² per 24 hours reference.
