REFRIGERATED

Why refrigerated vehicles need tracking

Temperature excursions can happen without the driver noticing: a door left open at a stop, a failing unit, a longer than planned delay. A cold chain tracking device records the trip continuously, so when a customer complains or an inspector asks questions, you have a timeline instead of guesswork. It also discourages unnecessary stops and detours that add time outside the controlled temperature range.

How to choose the right tracker

For refrigerated trucks, the practical choice is a unit that reads directly from the vehicle through CanBUS or supports external temperature sensors, since this is what turns a simple locator into a real temperature monitoring GPS tracker. Consider:

• CanBUS support for engine and reefer unit data, as in the Teltonika FMC150 4G and Teltonika FMB140 with CanBUS
• Input/output capacity for door sensors or external temperature probes
• Power supply suited to trucks, since these vehicles run long hours and sometimes idle with the engine off
• A rugged, easy to hide installation point, important on larger chassis with more wiring

Models such as the Teltonika FMB920, Teltonika FMC130 4G and Teltonika FMB920 cover simpler monitoring needs, while the Teltonika FMB900 is a lower cost 2G option for fleets that do not need every sensor input. The Teltonika TAT140 4G can serve as a backup tracker, reporting independently if the main unit loses power.

Installation and subscription

Installation on a refrigerated truck usually means connecting to a permanent power source, running any sensor cables neatly along the existing harness, and placing the unit where it is protected from moisture and vibration. We install trackers ourselves or guide installers who already work on your fleet.

Every tracker from Entopizo works with our own SIM card and our tracking platform on a subscription, which includes data transmission, access to the web platform and mobile apps, geofencing, and alerts for events such as unplanned stops, route deviation or power disconnection. A tracker without subscription can still store or transmit basic position data, but you lose live tracking, automatic alerts, and in many cases, the technical and customer support that keeps the device reporting correctly over time. Our subscription is designed so the device, the SIM and the platform work as one system, not three separate problems.

Real use cases

A distributor delivering dairy and frozen goods across Attica uses tracking to confirm delivery windows and settle disputes about delayed drop-offs. A pharmaceutical logistics company uses CanBUS data alongside temperature sensors to document that refrigeration never stopped during transport. A smaller operator with two or three trucks uses the lower cost options to keep basic visibility over the fleet without unnecessary features.

Frequently asked questions

Can a GPS tracker also monitor temperature?

The tracker itself reports location and vehicle data. To monitor temperature directly, it needs to be paired with a compatible temperature sensor or read data from the refrigeration unit through CanBUS, where supported.

Do I need CanBUS for a refrigerated truck?

It is not mandatory, but it is recommended, since it lets the tracker report engine status, fuel and other vehicle data alongside location, which is valuable for cold chain documentation.

What happens if the tracker loses power?

A backup unit such as the Teltonika TAT140 4G can continue reporting independently for a period, which is useful if the main power supply is cut or fails.

What does the subscription actually include?

It includes the SIM card and data connection, access to the live tracking platform and mobile apps, geofencing, and alert notifications. It does not require you to manage a separate SIM contract.
