Temperature mapping of chilled storage areas with racking

What do we map?

We use our calibration knowledge and experience to offer a tailored and competitive mapping service for;

  • Temperature Controlled Warehouses
  • Cold stores / Cold rooms
  • Production areas
  • Storage facilities
  • Laboratories
  • Server rooms

Our mapping process is accredited to ISO 17025:2017 standard and our mapping equipment is maintained with UKAS accredited calibration.

As our equipment is wireless, so all areas, of any size, can be mapped simply, cost effectively and in real-time. We analyse the collected data, develop reports, prepare protocols and undertake ongoing routine temperature mapping.​

What is temperature mapping?

Influences such as weather, stock holding, door openings and movement change the efficiency of refrigeration systems. This creates natural variants within a temperature-controlled area.

Temperature mapping shows variances over time allowing for corrective action planning, thus helping to remove risks to products.

Mapping reports provide a full overview of temperature over time allowing identification of areas of concern. To meet compliance, the report highlights these areas so the minimum standard can be met.

5 Steps to achieving Temperature Mapping

TekTroniks mapping studies provide UKAS ISO 17025: 2017 accredited temperature mapping surveys for your warehouse, storage and production areas.

Information required

1. The height, width and length of the area to be mapped.
2. Maximum height at which goods are stocked.
3. The minimum and maximum temperature thresholds for the area.

Steps for achieving a successful thermal mapping study.

Step 1 - Discuss your mapping project

A member of our specialist mapping team will discuss your project. Based on the information you have given us we can determine the most suitable system for your application, the number of mapping sensors required and the timescales to install and remove the sensors. If necessary we can arrange a site visit for one of our team to do a mapping site survey and discuss the project in person.

Step 2 - Mapping quote

We will provide a formal quotation for the work to be carried out.  If you are happy with the costs all you need to do is place an order.

Step 3 - Site visit

We will arrange a site visit to finalise the mapping scope document. This lays out in detail the mapping study including the number of points to be mapped, sensor locations, storage envelope and mapping period. We will also agree the date at which the mapping will take place.

Step 4 - Install mapping sensors

We will attend site and install the mapping sensors and logging equipment. This is left on site for the designated mapping period. We will then return to site to remove the equipment and extract the mapping data.

Step 5 - Present mapping report

We review all of the recovered data, complete a mapping report and return to site to present the mapping findings & report. Along with the mapping report we will issue a UKAS certificate for the mapping study.

Frequently asked questions

Is your temperature mapping process accredited?

Our mapping processes are designed around the WHO mapping standard and is accredited by UKAS to ISO 17025:2017.

We are accredited to complete temperature mapping in enviroments covering a temperature range of -45°C to 30°C.

On completion of the mapping study we issue a comprehensive mapping report together with a UKAS tracable calibration certificate.  Click here to see our UKAS accreditation schedule.

All our mapping sensors have a UKAS certificate.

What is the purpose of temperature mapping?

The purpose of temperature mapping is to determine if the storage area can maintain temperature within defined limits to demonstrate that it is suitable for the storage of temperature sensitive products.

Climatic conditions, air flow, footfall, load, machinery operation and door openings all have an effect on the areas temperature variation.

Temperature mapping gives greater insight into the temperature variations over these conditions to verify that the correct temperature levels are met in all situations.

Is temperature mapping a legal requirement?

Technically no, but if you operate in certain market sectors then it will be a requirement of the auditing bodies and must be completed.

Medical storage covered by the MHRA, FDA, CQC and other bodies have a requirement for mapping to be carried out. Documentation supporting mapping is usually reviewed as part of audit processes.

When should temperature mapping be performed?

The MHRA guidelines advise that a temperature mapping exercise should be carried out before use, under representative conditions.

It is good practice to complete mapping in each season phase or when the storage area has been reconfigured. The greatest effect to the performance of storage areas is external ambient temperatures.

We recommend mapping in 2 cycles, Winter/Summer & then Spring/Autumn.

Often this cycle would be a week, within these months;

Year 1 - January/February & July/August

Year 2 - April/May & October/November

Some audit bodies require on-going mapping while some require just a single year mapping over 2 periods.

We offer fixed term mapping contracts so cost can be budgeted if on-going mapping is a requirement. Or we can schedule a programme to suit your needs if one off mapping is needed.

How many sensors should I use for temperature mapping?

Though many regulatory bodies require mapping none say how to map, to meet their requirements. There are a number of sources on how to map but we base our process on those defined by the World Heath Organisation, see Temperature Mapping of Storage Areas (technical report series, no. 961, 2011) Annex 9.

The mapping area is defined as a grid layout with the calculation for the number of sensors based on variants including; length, width and height. We see sensor volumes of 12 to 300 plus, depending on area size.

As part of our ISO 17025:2017 accreditation mapping process we complete a site visit to; review the area to be mapped, agree the mapping scope, define the number of sensor and complete a drawing of the proposed mapping points. This scope document is agreed upon, signed and forms an important part of the documented process for audit purposes.

How long to perform a temperature mapping exercise?

The minimum mapping period is one week, including one full weekend.

For most applications a week is adequate, however should audit or legislative requirement mean mapping for longer then that would be agreed as part of the scope.

Sensor placement in temperature mapping?

For an effective mapping study the sensors should be placed to cover the entire space in a geometric pattern ensuring that the sensors are placed in area that will experience the extreme high and low temperatures.

Temperature mapping sensor grid layout

This information can then be used to ensure that the sensors used in continuous monitoring are placed in areas of most concern.

Humidity mapping for storage areas?

The specification of the goods being stored will determine whether you need to map humidity. The manufacturer will specify the humidity limits.

Our humidity & temperature mapping process is generally the same. We can map each factor individually or both at the same time.
