The low temperature and cryogenic insulation industry is constantly evolving. For progress and efficiency, high performance thermal insulation systems need to meet requirements from all the classification organisations in order to get Insulation Class Approvals. To verify the insulation is effective, validation tests must be done by recording temperatures at many points throughout the cargo hold. This was achieved using Fourtec MicroLite data loggers.
Application: Marine Cargo Holds for Pharmaceuticals and Food
Organization: MGI THERMO, Thermal Insulation Engineers
About the Customer:
MGI THERMO is a major engineering and contracting company specializing in thermal (cold) insulation of cargo holds for the distribution of pharmaceuticals and food supplies throughout the marine cargo industry. With their Head Office located in Drammen, Norway, they design and develop spray insulation systems for the holds of cargo ships.
Key Customer Challenges:
Marine insulation systems must deal with challenges at cryogenic temperatures which, if not kept in check, can potentially leading to cargo damage and huge financial losses. Hence the necessity for insulation of marine cargo holds, used for distributing perishable goods throughout the cold chain.
MGI THERMO first insulate the entire hold and, on completion of the insulation process, monitor temperature at multiple points to detect deficiencies in the temperature level. This process is to verify the quality of insulation for the ultimate protection of the cold chain cargo. The required temperature levels will vary depending on the content of any one particular cargo shipment.
MicroLite Implementation:
MGI THERMO installed multiple MicroLite LITE5032P- USB temperature logger units sporadically throughout the cargo hold area following completion of each foam insulation process. The units are then set at a sampling rate of 1 sample/min over a 24-36 hour period. Alarms are set, according to the required temperature range of each particular cargo, to measure, monitor and document any discrepancies outside of the set temperature range.
Measurable Results:
The MicroLite product line offers highly accurate, cost effective logging, designed with low power consumption, enabling more points to be monitored within a budget by repeatedly using the same loggers at multiple locations.
The MicroLite product provides high measurement accuracy and real-time sensor readings with a corresponding time stamp, which are displayed on the logger’s LCD screen, along with alarm thresholds to alert of any deviations in temperature in real-time.
The MicroLite device is used to verify that the data is reliable by using the complimentary DataSuite software which indicates any deviations from the defined measurement range. This means that the quality of the insulation work can be easily documented and reported, therefore verifying conditions for the safe shipping of cargo.
