NSnappy® Cool LWEU-N cooling transmitter

NSnappy® Cool is a cooling transmitter designed for accurate and automated measurement and monitoring cooling duration.

The NSnappy® Cool cooling transmitter is mounted on the GN container of the blast chiller and the probe is inserted in the food being cooled. NSnappy® Cool is activated by movement and temperature to automatically measure the cooling process. The temperature profile and cooling duration of the cooling process are automatically stored in the NSnappy® services over a LoRaWAN radio connection. In the NSnappy® service, you can add details on the foodstuffs that have been cooled and a batch code, for example.

In normal use, NSnappy® Cool operates for more than a year on its battery. The measuring device comes with the NSure continuous warranty for IoT measuring devices, which involves calibrating the unit regularly and replacing the battery.
