Confidence in your temperature-controlled environment
Thermal mapping is more than placing sensors, collecting data and issuing a report. The results need to demonstrate that your controlled environment is genuinely suitable for the products, materials or processes it supports.
Normec provides thermal mapping and requalification for temperature-controlled equipment and storage environments. Our specialists help identify temperature variations, assess critical areas and provide clear, traceable evidence of performance.
Where issues are identified, we look beyond the measurement itself to help understand what is causing the problem and what needs to be addressed.
What we map
Thermal mapping across controlled environments
Our thermal mapping and requalification services include:
- Fridges and freezers
- Cold rooms and controlled temperature units
- Incubators and stability chambers
- Warehouses and large-scale storage areas
- Automated warehouses with complex airflow zoning
- Humidity and environmental mapping where required
- Summer and winter studies
- Seasonal requalification
- Post-modification remapping
Mapping that reflects real operating conditions
A useful thermal mapping study needs to reflect how equipment or a storage environment actually operates. Sensor positioning, seasonal conditions and operating patterns can all affect the quality and relevance of the results.
Our specialists take these factors into account when planning and executing mapping studies, helping ensure that the resulting evidence provides a meaningful representation of performance.
This can be particularly important following equipment or facility modifications, changes in use or where previous mapping results have raised questions about environmental performance.
A structured approach to thermal mapping
- Define requirements
- Develop protocol
- Map
- Analyse
- Investigate
- Report
- Requalify
Our specialists develop mapping protocols around your product, process and operating environment. Using UKAS-traceable instrumentation, we collect and analyse temperature and, where relevant, humidity data and provide clear, audit-ready reporting.
Where results fall outside the defined acceptance criteria, our specialists can investigate the findings rather than simply documenting a failed result.
Technical expertise when results need explanation
A thermal mapping study should provide more than a pass or fail result.
When unexpected temperature variations or other issues occur, understanding the cause is essential. Our engineering specialists understand regulated environments and can help investigate unexpected results and determine where further assessment may be required.
This provides stronger evidence for quality and compliance teams and helps support informed decisions about the continued use or requalification of equipment and storage environments.
Our specialists can support you with:
- Initial thermal mapping and qualification
- Periodic or seasonal requalification
- Summer and winter mapping studies
- Mapping following equipment or facility modifications
- Reassessment following unexpected or inconclusive results
- Humidity or environmental mapping where required
- Mapping of new or modified warehouse environments
Reliable evidence for audits and inspections
Thermal mapping provides the evidence needed to demonstrate that temperature-controlled environments perform as intended.
With Normec's support, you benefit from:
- UKAS-traceable instrumentation
- Protocols tailored to your product and process
- Mapping across equipment and large-scale storage environments
- Support in investigating results that fall outside acceptance criteria
- Clear and audit-ready reporting

FAQ Thermal Mapping
-
Thermal mapping is the process of measuring and analysing temperature distribution within temperature-controlled equipment or storage environments. It helps demonstrate whether the environment is suitable for the products, materials or processes it supports.
-
Thermal mapping can be performed for fridges, freezers, cold rooms, incubators, stability chambers, controlled temperature units, warehouses and automated storage facilities. Humidity and wider environmental conditions may also be mapped where required.
-
Initial thermal mapping establishes how a temperature-controlled environment performs. Requalification confirms that the equipment or environment continues to perform as intended, for example following a defined period, seasonal change, modification or change in use.
-
Remapping or requalification may be required periodically, during summer or winter conditions, following equipment or facility modifications, after a change in use or when previous results have raised questions about environmental performance.
-
Seasonal conditions can affect temperature distribution within warehouses, storage areas and temperature-controlled equipment. Summer and winter studies help assess performance under different environmental conditions and operating scenarios.
-
A structured thermal mapping study generally includes defining requirements, developing a protocol, positioning sensors, collecting data, analysing the results, investigating unexpected findings, reporting and completing requalification where applicable.
-
Sensor positioning is based on the equipment, storage environment, product requirements, airflow, operating patterns and potential critical areas. The objective is to collect data that provides a meaningful representation of actual operating conditions.
-
When results fall outside the defined acceptance criteria, Normec’s specialists can investigate the finding rather than simply recording a failed result. This can help identify potential causes and determine whether further assessment, corrective action or requalification is required.
-
Yes. Normec uses UKAS-traceable instrumentation to collect temperature and, where relevant, humidity data. The results are presented in clear, audit-ready reports.
-
A thermal mapping report should provide clear and traceable evidence of environmental performance. It should document the study approach, collected data, analysis, identified variations, results against the acceptance criteria and any findings requiring further investigation.
