Walk-In Freezer Mapping & Validation Services
Defrost cycles are the freezer’s secret life — mapping catches what they do to your product zones.
ACS Calibration offers NIST-traceable walk-in freezer mapping and validation services at your facility across the Southeast. Studies evaluate temperature distribution and stability throughout the agreed study area.
Thermal mapping and validation studies are specialized NIST-traceable profiling services performed with calibrated data loggers; studies are conducted outside ACS Calibration’s ISO/IEC 17025 accredited calibration scope.
Cold Enough, Everywhere, Even Mid-Defrost
Walk-in freezers cycle through defrost events that briefly reshape the whole thermal map — and product near the evaporator or door experiences those swings hardest. A control sensor reading -20 °C on average can coexist with zones that spend defrost periods somewhere your spec never approved.
We map walk-in freezers with calibrated loggers through the storage volume and across multiple defrost cycles — uniformity, excursion behavior, and recovery documented against your acceptance criteria. See also walk-in coolers and freezer mapping studies.
What You Receive With Your Study
- Study setup and data logger locations.
- Recorded temperature data and study conditions.
- Temperature distribution and stability results.
- Evaluation against agreed acceptance criteria, where included in the study.
- Identification of the data loggers and their calibration references.
