A Temperature mapping service is designed to determine the temperature profile of equipment or facilities where temperature sensitive products are stored. Mapping will then provide data to support product placement and contingency plans.
A number of sensors are placed around the area to be monitored. Typically for smaller items of equipment 10 sensors are used. 9 sensors are placed internally; 4 in the bottom corners, 4 in the top corners and 1 in the centre. A 10th sensor is used to measure the ambient value outside the equipment. For larger storage devices and environments form sensors may be required.
Britannia's Mapping protocol involves initially carrying out 24 hour test with the environment empty, turned on and with the door or access remaining closed. This provides the user with data for product placement when the environment is in a stable condition.
The equipment is then monitored under a number of changing conditions. A power off test is performed - This test identifies the temperature decline over time to identify potential "hot spots" within the environment, where temperatures rise most quickly once power is lost, while ensuring the temperature remains within acceptable limits for the duration of the test.
Next door opening tests - This test identifies areas near the door as potential "hot spots" and by placing temperature sensors strategically around the door opening to monitor temperature fluctuations during door openings, while also considering the duration of door openings to accurately assess the impact on overall temperature; this helps to determine if the environment can maintain proper temperature even with regular access.
The 24 hour test, power off and door opening tests can then be repeated with the environment filled with packaging and simulation products to provide additional data.
Once mapping is completed this data can then be analysed to indicated third party sensor placement and develop alarm thresholds and emergency plans in the event of a worst-case scenario such as knowing the duration the freezer can maintain the required safe environment.
Mapping should be completed on new equipment and repeated at regular intervals to monitor deterioration.
