Why ColdGuard?

Built from the ground up for the harsh environmental and infrastructural realities of rural medical distribution in Ghana.

MKT Math Validation

Calculates Mean Kinetic Temperature using the Arrhenius equation — mathematically proving whether a batch is safe after a "Dumsor" power outage or heat spike.

Offline Store-and-Forward

A true "No Network" protocol — hardware logs to SD Card, nurses sync seamlessly via BLE onto the mobile app, bridging the gap until internet is restored.

Rugged Fail-safes

Capacitive "no-hole" touch sensors, PETG cases for motorbike transit, and active Magnetic Reed Switches to prevent basic human errors like open lids.

Our Impact on the Ground

From the clinic fridge to the furthest village — ColdGuard protects every step of the cold chain.
