Off-grid vaccine refrigerator that also freezes PCM packs, so one unit covers the health post and outreach. Ships complete with solar kit, battery and two 4 L carriers.
Ships complete as a kit. Program and quantity pricing on request.
Eliminates cold spots and holds vaccines at the right temperature.
More than 3,000 cycles and a minimum 10-year service life, with battery monitoring and load control.
Sized for just 2.0 kWh/m²/day of sun, well below the 3.5 commonly used, so a 310 Wp kit is enough. The panels go on a normal roof or ground mount, with no east-west array or pole mount. On rainy days it keeps vaccines cold for 136 hours.
2 USB and 4 barrel ports for lights and phone charging (optional on some models).
Ships with battery, panels and mounting. Swap in your own components if your program requires it.
Warranty: 2-year replacement parts warranty and a 7-year limited prorated warranty on the LiFePO4 battery. Replacement parts only; freight, duties, installation and field labour are not included.
