Protect Product, Qualify Pharma Lanes, Pass Every Audit

Refrigerated semi truck transporting temperature-sensitive products

Temperature mapping verifies equipment performance under real-world operating conditions. Whether validating a refrigerator, freezer, cold room, or refrigerated truck trailer, our studies:

  • Identify worst-case temperature zones
  • Determine and recommend permanent monitoring sensor locations
  • Evaluate performance under expected operating conditions
  • Deliver audit-ready documentation suitable for GDP and GMP compliance

GDP- and GMP-Compliant Mapping Studies

Our temperature mapping studies are conducted in full alignment with Good Distribution Practice (GDP) and Good Manufacturing Practice (GMP) requirements and include:

  • Demonstrated temperature uniformity throughout the trailer under controlled test conditions
  • Verification of performance under steady-state, door-open, and simulated power-failure scenarios
  • Comprehensive documentation suitable for regulatory audits and quality reviews
  • Use of calibrated, NIST-traceable temperature sensors to ensure data integrity and defensibility

These studies provide objective evidence that equipment can maintain required temperature ranges, supporting lane qualification, validation, and ongoing compliance.

Trailer Temperature Mapping

Qualify your refrigerated trailers to meet pharmaceutical Good Distribution Practice (GDP) expectations. Our temperature mapping documents how a refrigerated trailer performs across real-world operating conditions. We provide audit-ready trailer temperature mapping for carriers transporting pharmaceuticals, medical devices, vaccines, and other temperature sensitive products.

Qualify your refrigerated trailers to meet pharmaceutical Good Distribution Practice (GDP) expectations. Our temperature mapping studies document how refrigerated trailers perform under real-world operating conditions. We deliver audit-ready data that demonstrates temperature uniformity, identifies worst-case locations, and supports compliant monitoring practices.

We provide trailer temperature mapping services for carriers transporting:

Why American Thermal Instruments

Efficient report turnaround

We have in-house quality professionals and scientists. This allows us to deliver completed, audit-ready temperature mapping reports faster than traditional providers. Our streamlined data collection, processing, and reporting workflows eliminate manual bottlenecks that commonly delay report issuance.

Competitive project cost

By optimizing how temperature data is captured, analyzed, and transferred into validated report formats, we reduce internal labor and administrative overhead. These efficiencies are passed directly to customers through lower total project costs.

Audit-ready documentation

Reports are delivered in a format aligned with pharmaceutical GDP expectations and are designed to be shared directly with quality teams, pharmaceutical customers, and auditors — without rework or reformatting.

Proven protocols and methodology

We use structured, repeatable mapping protocols that evaluate steady-state performance, door-open recovery, and power-failure recovery across all required temperature ranges, generating defensible compliance data.

Minimal operational disruption

Mapping studies are executed efficiently at the carrier’s facility with clear setup instructions and defined timelines, minimizing trailer downtime and operational impact.

FAQ

WHEN SHOULD TRAILERS BE MAPPED?

  • New trailers are added
  • After repair or significant change has occurred to trailer
  • Customer request or in line with customers’ audit schedule
  • Current trailers should be mapped on an annual basis

WHAT CRITERIA ARE USED?

We document GDP/GMP-aligned criteria in the protocol and include pass/fail tables and statistics in the report.

CAN MAPPED TRAILERS BE USED TO QUALIFY LANES FOR VACCINES?

Yes — mapping demonstrates trailer performance and is often required by pharmaceutical shippers before lane approval.
