Catch Reefer Problems Before Cargo Is Lost
Catch reefer excursions before cargo is lost — wireless temperature and door alerts on every trailer, with audit-ready history for customers and QA.
One temperature excursion can mean a rejected load, an insurance claim, and a customer you may not get back. Most fleets still discover problems at delivery — not while there is time to fix the reefer or reroute the load.
The challenge
Cargo loss is expensive
produce, pharma, and frozen goods have narrow safe ranges
Reefer faults hide
a unit can drift out of spec hours before anyone notices
Door events matter
an open door at the wrong stop can ruin an otherwise good run
Audit gaps
customers and regulators expect timestamped proof, not driver notes
Who this is for
Reefer and cold-chain carriers
hauling food, beverage, pharma, or chemicals
Fleet managers
responsible for FSMA, GDP, or customer QA programs
Dispatch teams
that need to intervene before product is lost, not after rejection
Mixed fleets
adding temperature visibility without rewiring every trailer
What you gain
Early warnings
phone alerts when interior temperature drifts out of range
Door correlation
see whether a stop, door opening, or reefer fault caused the excursion
Audit-ready history
timestamped logs for customers, insurers, and regulators
No trailer wiring
wireless BLE sensors pair to a solar-powered tracker
One dashboard
location and temperature on the same map your dispatch already uses
Real-world use cases
Produce hauls
catch a reefer set-point error before pallets warm up in transit
Pharmaceutical freight
document continuous temperature for GDP and chain-of-custody reviews
Multi-drop routes
flag unexpected door openings between scheduled stops
Seasonal reefer fleets
add sensors to peak-season trailers and move them as contracts change
How Valentir helps
ValenSolar mounts on the trailer with solar charging — no wiring run. BLE temperature and door sensors relay data wirelessly to the tracker and ValenInsights. You get location, temperature history, and alerts from the same platform you use for the rest of your fleet.
Getting started
Tell us how many reefer trailers you run, what you haul, and who needs the audit trail (customers, QA, or regulators). We will recommend sensor placement and a rollout plan that fits your lanes and loading patterns.
