Novel data logging technology is helping an industry-leading frozen and chilled food distribution company to assure their customers that products are being stored and transported in perfect environmental conditions.

Igloo Thermo-Logistics provides refrigerated transport nationally and throughout Europe, and uses Gemini Data Loggers’ Tinytag loggers to monitor and record the temperature of their customers’ products. Gemini has manufactured the Tinytag range in the UK for the last 19 years, and initially supplied Igloo with small, battery powered stand-alone loggers for widespread use in Igloo’s refrigerated vehicles, providing evidence they are conforming to the specific requirements of their customers.

Following the launch of Gemini’s Radio Logger technology, Igloo incorporated a new system at its facilities in Watford and Leeds. This effective, low cost monitoring and alarm system automatically takes real-time data from multiple points in the company’s cold rooms. Live temperature data can be monitored continuously from any location worldwide, with alarms set to send text and email alerts to key staff if temperature deviations occur.

The Tinytag Radio system consists of a number of radio loggers connected wirelessly to a receiver. The receiver is connected to a central PC running Tinytag Explorer Radio software that continuously collects and stores data from the remote loggers. The radio loggers work together as a ‘mesh network’: if one logger is temporarily unable to communicate with the receiver, its data hops to its nearest neighbour and hence finds a path back to the receiver. If connection is lost with neighbouring loggers and the receiver, data is stored locally until communication is restored. With a 200 metre range and sensor cables that can extend up to 10 meters, the loggers can be strategically positioned to maximise radio connectivity.

Igloo MD Alistair Turner is delighted with the system. He says, “Temperature control is vital for our clients: we initially chose stand-alone Tinytags, after trialing other products, because they proved robust enough to withstand extremes of temperature and physical abuse. Subsequently the radio loggers offered a lower labour requirement with even greater assurance for our temperature control systems.

“The simplicity of the new system meant that costs were very low; we installed the software, connected the receiver and mounted the loggers. Then, with the sensors in position, we turned on the loggers and the system automatically created the mesh network. Alarm levels were configured at the central PC and since then, the system has effectively run itself.”
