Thermal Mapping

Temperature and humidity distribution studies for storage areas, cold rooms, freezers, warehouses and transport vehicles per WHO guidelines.

Overview

What thermal mapping means with QCS

The purpose of a thermal mapping study is to document and control the temperature distribution within a storage area, cold room, freezer room or other temperature-controlled store.

Temperature mapping is essential for organisations handling temperature-sensitive products — medicines, vaccines, biochemical products, fresh and treated foods, frozen goods, dairy and meat — and is supported by ongoing monitoring systems.

Scope of work

What is covered

Each engagement is scoped in writing before any engineer arrives on site.

01

Warehouse & store mapping

Sensor grid design, empty and loaded studies, summer and winter cycles with hot/cold spot identification.

02

Cold rooms & freezers

Distribution and stability studies including door-opening and power-failure excursion testing.

03

Transport vehicle mapping

Qualification of refrigerated vehicles and shipping lanes per WHO GDP guidelines.

04

Monitoring system setup

Placement of permanent monitoring sensors and alarm limits based on mapping results.

What you receive

The paperwork is the product.

An engagement is not finished when the engineer leaves — it is finished when your quality unit has the records in hand.

  • Mapping protocol with sensor layout drawings
  • Calibrated data-logger certificates
  • Graphical temperature/humidity profiles
  • Hot & cold spot report with monitoring-point recommendations
FAQs

Thermal Mapping — common questions

Thermal mapping documents and controls the temperature distribution inside a storage area, cold room, freezer or vehicle. It is required for organisations handling temperature-sensitive products — medicines, vaccines, biological products and foods — and identifies the hot and cold spots where permanent monitoring sensors must be placed.

A typical study runs a minimum of 24 to 72 hours per condition. Warehouses are usually mapped empty and loaded, and in both summer and winter conditions, to cover the worst case across the year.

Yes. We qualify refrigerated vehicles and distribution lanes as per WHO GDP guidelines, including door-opening and power-failure excursion studies.
