Thermal Mapping Services
Thermal Mapping Services in Pakistan
On-site temperature mapping across Pakistan for warehouses, cold rooms, freezers and controlled storage. Share your site location and area details for a study plan and quotation.
Mapping applications
Temperature mapping for storage areas, equipment and distribution routes.
The study design should match the controlled space, operating range, load condition, access pattern and purpose of the mapping exercise. EPC can also support related calibration services and validation services when included in the agreed scope.
Cold Room Mapping
Mapping support for cold rooms based on dimensions, set limits, load state, door activity and operating conditions.
Freezer and Chiller Mapping
Study planning for freezers, chillers and low-temperature equipment within the feasible operating range.
Vehicle Mapping
Temperature distribution review for selected transport vehicles and insulated distribution spaces under agreed conditions.
Chamber Mapping
Mapping support for stability chambers, incubators and selected controlled environmental equipment.
Refrigerator Mapping
Temperature mapping for refrigerators and selected storage equipment used for controlled products or samples.
Temperature requirements
Thermal mapping for your required temperature range.
Need a study below 30°C, 25°C, 20°C or 0°C? Start with the product's required storage conditions. The options below help define a mapping enquiry; they are not universal storage standards or a guarantee of equipment capability.
Below 30°C mapping
For a requirement that specifies storage below 30°C. Share the exact label wording, any lower limit and the warehouse layout so the study can assess the intended storage positions.
Below 25°C mapping
Use this option when the specified upper threshold is 25°C. “Below 25°C” does not by itself define a 15–25°C range; confirm any lower-temperature or no-freezing requirement separately.
Below 20°C mapping
For a product or process specification requiring temperatures below 20°C. Provide the full acceptance limits and normal operating conditions; this threshold alone does not define a refrigerated range.
15–25°C storage mapping
Where the approved requirement is 15–25°C, both the lower and upper boundaries matter. Ask for the location-based records to be reviewed against both limits, not only the room average.
2–8°C cold-room mapping
For cold rooms with a specified 2–8°C storage requirement. Confirm the load condition, access pattern and both acceptance limits before deciding the study arrangement.
Below 0°C freezer mapping
Sub-zero enquiries need an exact operating range. A reading below 0°C does not establish suitability for every frozen product. EPC must review the required limits and logger capability before confirming feasibility.
A set point is not an acceptance range. Include the required lower and upper limits, any humidity requirement, area dimensions and site location. EPC can then review an appropriate mapping scope and quotation.
Discuss your temperature range →Range selection reference: WHO guidance on temperature mapping of storage areas. Apply the relevant product requirements and approved site protocol; the example categories above do not replace them.
Understanding the results
What does a temperature mapping study show?
Thermal mapping records temperature at different positions over an agreed period. It helps identify warmer and colder locations and assess how storage conditions compare with defined limits. The findings depend on the layout, load, operating cycle and conditions recorded during the study.
What your mapping report can include
Confirm the following deliverables in your quotation and approved study scope before deployment:
- Study setup: the area, agreed limits, study period, load conditions and logger-location plan.
- Temperature records: location-based readings and trends for review against the agreed limits.
- Findings: observed hot and cold locations, excursions and recommendations where included in the scope.
- Supporting records: logger identification and the calibration documentation agreed for the study.
Discuss additional analyses and qualification documents separately. Report conclusions apply to the conditions assessed; product-release decisions remain with your responsible quality team.
Discuss your report requirements →Mapping and monitoring do different jobs
Mapping studies temperature distribution across a space for a planned period. Ongoing monitoring tracks conditions at selected locations during routine operation. Mapping findings can help inform where monitoring devices should be placed; they do not replace continuous monitoring.

A practical reading example
Read the location, not just the room average.
Imagine a warehouse with an agreed study range of 15–25°C. The invented readings below show how different locations can raise different questions during report review.
Illustrative example only — not an EPC client report. All readings and position labels are fictional. The range is an example, not a universal storage limit. Three rows do not represent a complete logger-placement plan.
| Example point | Minimum / maximum | What the summary tells you |
|---|---|---|
| A — middle rack | 17.6°C / 23.8°C | Both extremes fall within the assumed range; this alone does not qualify the whole warehouse. |
| B — upper rack | 19.2°C / 26.1°C | The maximum is 1.1°C above the example upper limit. Review when it occurred and the surrounding records. |
| C — lower rack | 14.4°C / 21.9°C | The minimum is 0.6°C below the example lower limit. Review the location and operating context. |
What this example cannot tell you
Minimum and maximum values alone do not show excursion duration, repeated events or missing data. Request the time-series records before drawing those conclusions. A single extreme also does not establish a persistent hot or cold spot.
Turn a finding into a review question
Was a door opened? Did the load or cooling cycle change? Which logger and rack height produced the reading? These questions help make a report useful. Product-release decisions require the responsible quality team and applicable product information.

Study design matters
Logger quantity and placement depend on dimensions, layout and risk points.
Details for scope review
Share the controlled area, limits and expected study conditions.
Photographs, drawings or a simple sketch help EPC understand racks, doors, airflow paths and equipment that may affect temperature distribution.
- Area or equipment name and internal dimensions
- Required temperature range and acceptance limits
- Empty, loaded or representative operating condition
- Study duration and normal operating schedule
- Door locations, racks, cooling units and known risk points
- Site location, access and report requirements
Mapping lifecycle
A controlled route from protocol planning to final report.
The exact method depends on the area and client requirements, but study decisions should be documented before logger placement.
Area Review
Dimensions, layout, use, limits and operating conditions are collected.
Study Plan
Duration, logger placement, conditions and acceptance approach are agreed.
Deployment
Loggers are positioned according to the approved study arrangement.
Data Review
Recorded data is organized and reviewed for temperature distribution.
Reporting
The study report presents the agreed results, observations and records.
Plan the right study
Which operating conditions should mapping represent?
Choose the question before choosing the test. EPC reviews the proposed study conditions with your facility team before confirming the service scope.
Empty and loaded conditions
An empty-area study and a study with representative stock answer different questions. Document the loading arrangement and intended use so the report's conclusions stay within the conditions actually assessed.
Seasonal temperature mapping
Weather-sensitive storage may need warm- and cool-season comparison. This is not automatically the same requirement for every cold room or freezer; assess external influence and the facility's applicable protocol.
Door-opening and power events
Agree any challenge, observation period and safety controls in advance. Do not deliberately interrupt a live storage system simply to collect data without the site's authorization and product-protection arrangements.
Changes and repeat mapping
Reconsider the study after significant layout, loading or cooling-system changes, or unexplained monitoring excursions. Review what changed instead of assuming an old result covers the new operating arrangement.
Planning reference: WHO guidance on temperature mapping of storage areas. This overview does not replace a site-specific protocol or establish EPC accreditation or WHO endorsement.
Risk factors
Mapping should reflect the conditions that can change temperature distribution.
Known risks help determine study design, logger placement and the operating context recorded in the report.
Doors and AccessOpening frequency, loading activity and nearby traffic can affect local conditions.
Racks and Product LoadStorage configuration may influence airflow and temperature response.
Cooling and AirflowSupply, return and circulation paths can create warmer or colder locations.
External ExposureWalls, roofs, sunlight and adjacent spaces may affect seasonal performance.
Defrost and CyclingEquipment cycles can produce expected short-term temperature movement.
Power and AlarmsKnown interruptions or alarm events should be recorded with the study context.

Thermal mapping FAQ
Common questions before a mapping study.
What areas can EPC review for thermal mapping?
EPC reviews warehouses, cold rooms, freezers, refrigerators, chambers and selected vehicle or transport applications. Feasibility depends on dimensions, operating range, access and study requirements.
How many data loggers are required?
Logger quantity cannot be confirmed from area name alone. Dimensions, layout, racks, doors, cooling arrangement, risk points and any client protocol requirements must be reviewed first.
How long should a thermal mapping study run?
Duration depends on the controlled area, operating cycle, product or process requirement, client procedure and purpose of the study. It should be agreed during protocol planning.
Can mapping be performed under loaded conditions?
Yes, where the study scope requires it and operations can support the planned arrangement. The selected load condition should be documented before deployment.
What is included in the thermal mapping report?
Report content depends on the approved scope and may include study details, logger arrangement, recorded data, observations and conclusions appropriate to the agreed protocol.
