A reefer that drifts out of range at 2 a.m. does not announce itself. Too often you find out at the customer's dock, when the load is refused and the driver is already headed to the next stop.
Geotab cold chain puts reefer temperature monitoring on the same map as your trucks, trailers and drivers, in near real time, from the dock to the door. For food and beverage fleets running dozens of reefers out of one warehouse or many, this is the difference between catching a problem on the road and hearing about it from the customer.
Multi-Zone Reefer Temperature Monitoring in MyGeotab
A mixed load is not one temperature. Frozen rides in one compartment, chilled in the next. The Geotab IOX-COLD add-on reads each compartment on its own, with readings for up to 3 zones per reefer, so a warm rear zone never hides behind a cold front one.
Everything lands on one Cold Chain page in MyGeotab: each zone's temperature beside its setpoint, with door status and reefer data alongside, next to the location and trip history for the same truck. Your team checks temperatures where it already checks everything else, with no second system to log into.
We hold Geotab cold chain certification, and every unit ships configured and Plug-N-Play, so your reefers report from day one.
Cold Chain Alerts When a Zone Drifts Out of Range
Monitoring pays off only when someone acts on it. Each zone gets its own out-of-range rule: you set the safe band and how long a reading can sit outside it before the alert fires. A quick door-open spike at a delivery stays quiet. A unit losing ground on the highway does not.
With Geotab custom alerts, each warning goes to the person who can act on it, by email or in-app notification: the driver, the dispatcher, the operations manager at that branch. Alerts cover reefer unit trouble as well as temperature, so word of a failing unit reaches your team while the load is still on the truck. Nobody has to watch a dashboard all night.
Cold Chain Fleet Tracking: Trucks, Trailers and Drivers on One Map
A temperature reading means more when you also know where the load is and who is driving it. Geotab GPS vehicle tracking puts every truck live on one map with trips, stops and driver behavior, so dispatch answers an ETA call and a temperature call from the same screen.
Trailers stay visible too. IOX-COLD puts reefer trailers on the map, and Geotab GO Anywhere covers the dry vans and unpowered trailers waiting at a dock or drop yard. It runs on one battery with nothing to wire or recharge, and it checks in hourly.
Drivers run hours of service, inspections and messages in the Geotab Drive app, so the whole day sits on one record beside the load.
Watching your own trucks on the map beats reading about it. Get a free demo device, configured before it ships.

When a customer questions a load, the conversation should end with data, not memory. Geotab keeps the temperature history in MyGeotab, so your team pulls any trip zone by zone and answers with proof of delivery.
The same traceable record backs you up when an auditor or a key account asks to see it. It settles internal questions just as fast: which branch, which unit, which hour.
Over time the pattern matters as much as the single load. Units that drift often and routes that run warm show up in the history long before they show up in a claim.
Built for Multi-Site Distributors and Public Fleets
Food and beverage distribution rarely runs out of one building. With Geotab enterprise fleet management, each branch, depot or region gets its own users, rules and reports, while leadership sees the whole operation on one login. A new branch joins the same account, so growth never means a second system.
Public fleets that move food get the same discipline. School nutrition programs and correctional food service answer for every load, and every route carries the same zone-by-zone record. A district running several central kitchens sees every truck, every zone and every stop on one account, with each site seeing its own.
Geotab Cold Chain Setup and Support
We have served fleets since 1999, and it starts with a free demo device on your own vehicles. When you roll out, we build your groups, zones and rules before the first device ships, and we stay on the phone until every device reports.
After that, a dedicated U.S.-based team answers in minutes. Once your contract is signed, our Fixed Pricing Guarantee locks your price for the rest of it. Trucks, reefers and trailers all come from one team and report into one account.
FAQ
How many temperature zones can Geotab monitor on a reefer?
Geotab cold chain monitors up to 3 temperature zones per reefer, each with its own safe range and alert rule. That covers multi-temp loads, frozen and chilled, on the same trailer.
What happens when a reefer zone goes out of range?
MyGeotab sends an alert when a zone stays outside the safe range you set for longer than the time you allow. The alert goes by email or in-app notification to the people you choose, so the driver or dispatcher can act while the load is still on the truck.
Can I show a customer the temperature history for a delivery?
Yes. Geotab cold chain keeps the temperature history for each trip in MyGeotab, with proof-of-delivery reporting, so you can show a customer the readings behind a delivery. The same record answers auditors and key accounts.
Does Geotab track trailers that have no reefer?
Yes. Geotab GO Anywhere tracks dry vans and unpowered trailers on one battery, with nothing to wire or recharge. It checks in hourly, and every trailer shows on the same map as your trucks and reefers.
