Your refrigerator will fail on a night when nobody is there.

National Cold Vault builds a cellular temperature monitor for medical refrigerators — the private-stock vaccines, GLP-1s, insulin, allergen extracts, and biologics you paid for yourself. It runs on its own 4G LTE connection and its own battery, so it keeps working when your Wi-Fi drops, your password changes, or the power goes out.

The fridge the state doesn't cover

If you're a VFC provider, Ohio gives you a logger for the state-supplied vaccine. It does not cover the refrigerator holding the inventory you bought — private-stock flu and Shingrix, GLP-1s, insulin, allergen extracts, compounded preparations. That's the fridge you'd replace out of pocket.

Independent 4G Connectivity

Our hardware bypasses local Wi-Fi networks entirely. Each unit ships with a pre-configured LTE cellular modem, transmitting encrypted telemetry directly to our secure cloud infrastructure.

What happens at 2 a.m.

When a probe reads out of range — or the unit loses power — the system places a phone call. Not a push notification that sleeps with your phone. It calls, then texts.

Alert timing is being measured through September 2026.
