Spoilage & write-offs
An undetected breach turns a full load into a write-off. By the time the depot notices, the truck is already at the customer — and the freight is past the point of no return.
Cold Chain · Temperature-Critical Fleets
Every degree, every
minute, every load.
Multi-zone Bluetooth temperature sensors integrated with Fleet Destiny — for pharmaceutical, food, and fresh-produce fleets that can't afford a thaw.

The Reality
Cold chain is unforgiving.
One temperature excursion can cost hundreds of thousands — in spoiled stock, regulatory fines, or a lost contract.
Customer records & claims
Customers often ask for a clear temperature history before accepting a disputed load. Manual records are slow, incomplete, and difficult to match with the vehicle, route, or exact delivery time.
No visibility in transit
Once a reefer leaves the depot, most fleets are flying blind. Door openings, compressor glitches, and route deviations go unnoticed until something goes wrong — and by then, the cost is already locked in.

Advanced vehicle intelligence · FMC150
The bridge between the load, the vehicle and your control room.
For advanced cold-chain deployments, the FMC150 combines live location, built-in CAN data processing and external sensor inputs in one compact 4G device. That means temperature, cargo-door activity, driver identity, fuel use and vehicle health can share one operational timeline.

Case Study
Representative18-vehicle reefer fleet · Western Cape produce distributor
Zero temperature excursions in 8 months — and audit prep dropped from 2 hours to 10 minutes.
A Western Cape produce distributor supplying fresh fruit and vegetables to a major supermarket chain had recently absorbed a R280,000 loss and a compliance warning from a single missed temperature breach. After deployment, the operation maintained a perfect cold-chain compliance record across 18 reefer vehicles — three temperature zones per truck, monitored continuously, exported to retailer audit format on demand.
18 vehicles monitored across 3 temperature zones each
Audit documentation cut from 2 hours to 10 minutes
