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 Pulsavant helps
PulseSolar mounts on the trailer with solar charging — no wiring run. BLE temperature and door sensors relay data wirelessly to the tracker and PulseInsights. 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.
