Cold chain: monitoring your refrigerated trailers

A pharmaceutical or food load does not forgive approximation: two degrees too high for an hour, and the pallet goes in the skip, with a dispute on top. Real-time monitoring completely changes the carrier's position.

The problem is not the fridge unit, it is the blind spot

Modern refrigeration units are reliable. What costs money is the blind spots: the door left ajar at the dock, the unit that stops over the weekend break, the thermostat knocked out of adjustment after servicing, the trailer plugged into a faulty socket. Without continuous measurement, you discover the problem at delivery, when there is nothing left to save.

How our monitoring works

Bluetooth temperature and humidity sensors are placed inside the body, with no wiring, and report their readings through the trailer's tracker. You set your thresholds by type of goods; if a reading drifts, the alert goes out immediately, to dispatch or to the driver. Door-opening detection completes the setup: a door opening away from a planned site, at 3 a.m., is known straight away.

Everything lives on the same platform as the rest of your fleet: positions, temperatures and events in one place, trailer by trailer. The hardware details are on our asset tracking page.

The history that closes disputes

The temperature of every journey is recorded and timestamped, exportable in one click. Faced with a claim, you produce the complete curve for the transport: loading, journey, delivery. Either it clears you, or it pinpoints the link that failed. In both cases the discussion is short, and your principals appreciate receiving the proof without having to ask for it.

Three frequent use cases among our customers

  • Pharma and food: strict thresholds, immediate alerts, compliance reports per delivery.
  • Subcontracted trailers: the temperature stays visible even when the trailer is pulled by a third-party tractor unit.
  • Idle fleet: an alert if a unit stops on a loaded trailer over the weekend.

Sensor battery life is measured in years, fitting in minutes. The longest part is choosing the thresholds.
