Survey Information

Surveys are normally carried out once in summer and once during winter, additional surveys may be required as follows:-

• After the installation of new racking.
• When existing racking is moved or
• When major adjustments have been made to the existing heating/ventilation systems as these adjustments will affect the airflow within the storage area.

The survey will reveal the location of any hot and cold spots within the facility, identifying potential irregularity in the heating/refrigeration systems. Once an irregularity has been found it may be necessary to avoid storing products at that specific location or take remedial action to rectify the situation. The survey will also identify the effects on the ambient temperatures of doors opening and closing, particularly relevant where there is vehicle entry and exit. The data will identify the recovery time of the installation to its normal operating parameters and can be used to help determine the ideal distances of racking from these access points.

Temperature loggers are placed throughout the facility by TeDaC and are left in situ typically for a minimum of 7 days, during which time normal facility operations are unaffected during the mapping process. The loggers are then collected and the information downloaded to PC from which a full report is produced.

All temperature loggers are calibrated on a six monthly basis and calibration is traceable to UKAS, copies of the calibration certificates are provided within the report. 3 point calibration is used as standard; however, more points can be included if required. It is also possible to carry out pre and post survey calibration if specified by the client.

The price of each mapping survey is dependant on a variety of factors including the size of the facility and the number of calibration points required. TeDaC would be happy to discuss your requirements and provide a free no obligation quote.
