Vehicle Temperature Mapping
Wireless Temperature Mapping
Qualification mapping for refrigerated vehicles and trailers. Documents temperature distribution across cargo zones under loaded and unloaded conditions to verify EN12830 compliance, with annual re-mapping recommended for regulated fleets.
Refrigerated Vehicle Qualification
Regulatory authorities and GDP auditors require documented proof that refrigerated vehicles maintain uniform temperature across the full cargo space under real operating conditions — not just at a single probe near the evaporator. Without a formal qualification study, fleets transporting medicinal products or controlled foodstuffs face non-compliance findings that can halt distribution operations.
How it's deployed
Wireless sensors are placed at a minimum of nine positions inside the cargo compartment — front, middle, rear at three heights — and data is collected under both loaded and unloaded conditions across at least one full delivery cycle. The sensors are battery-powered clip-on units that attach to existing racking without modifying vehicle infrastructure, and they pair to a compact in-cab gateway that buffers data if cellular coverage drops during transit.
Evidence & Reporting
Each vehicle receives an individual EN12830-compliant qualification certificate documenting cargo zone temperature distribution, exceedance events, and a pass or fail determination against the defined temperature range. GDP Chapter 9 requires annual re-qualification of refrigerated transport, so the report is dated and version-controlled to support your fleet re-mapping schedule.

Frequently Asked Questions
GDP guidance and EN12830 require individual qualification for each vehicle because even identical models can differ in insulation condition, door-seal integrity, and evaporator performance. A single reference study cannot substitute for per-unit documentation when transporting medicinal products. For large fleets we can run parallel mapping campaigns across multiple vehicles simultaneously to reduce downtime.
Annual re-mapping is the standard GDP recommendation, but re-qualification is also required after any refrigeration unit repair, body damage, seal replacement, or change in the temperature range the vehicle is approved to carry. We flag approaching re-qualification dates in the delivered report so your logistics team can schedule studies proactively.
Mapping during live delivery runs is possible and often preferred because it captures real-world door-open frequency and ambient exposure that static tests do not replicate. The wireless sensors and in-cab gateway operate without driver involvement and do not interfere with refrigeration controls.
