The PolarBoxmeasures, learns, calculates and alerts in the event of a leak or default
The PolarBox is an intelligent system dedicated to the remote supervisions and leak detection of refrigeration installations. Thanks to a weighing system, pressure and temperature measurements taken every 3 seconds, as well as dedicated algorithms, the PolarBox performs continuous leak detection.
Capable of learning the normal operation of a refrigeration installation, the DNI determines a reference level and thus triggers the right alarm, at the right time. Patented since 2009, it complies with regulatory requirements for leak detection.
The PolarBox is capable of monitoring 4 refrigeration systems simultaneously.
The Matelex PolarBox is suitable for all installations with a HP (High Pressure) liquid tank: vertical, horizontal or horizontal inclined tanks.
The PolarBox works with all refrigerants, and has more than 120 pre-registered fluids, including CO2 and ammonia (NH3).
The PolarBox is connected to the PolarVisor web interface. This secure portal allows remote monitoring of refrigeration installations via performance analysis tools, alerts and technical advice dedicated to optimizing the operation of the installations.
The PolarBox has an integrated 4G connection.
Two types of alarms alert in the event of a leak :
- A classic low level alarm: if the level falls below the threshold determined on site or remotely, an alarm is triggered.
- A so-called "statistical" alarm from learning how the installation works. Once the DNI is installed, it will take a few days to identify normal variations in the refrigerant level and abnormal variations. The DNI is thus able to determine a reference level, and to alert as soon as it moves away from it.
For which type of tanks?
The DNI is suitable for all types of tanks. Whether vertical, horizontal or even
inclined tanks, the DNI is able to calculate the levels and volumes of refrigerant.
Single vertical tanks
Horizontal tanks on outdoor bodied units
Double vertical tanks
Single and inclined horizontal tanks
For which refrigerants ?
the DNI library, including CO2 and ammonia (NH3). It is even possible to create your own mixtures.
How does the PolarBox communicate ?
The DNI is connected to the PolarVisor web interface. Several connection options are available: wifi, ethernet / RJ45 cable or via a 3G / 4G card. The connection to PolarVisor brings many advantages such as assistance with fault identification, automatic updates, an additional year of warranty and an easier after-sales service. Note: the exchange of information between the DNI and PolarVisor is secure thanks to data encryption.

Our open training courses
Would you like to learn more about the DNI and its modules, train yourself in their installation or in the use of Sentinelle?
We organise practical training courses adapted to your needs.
Matelex supports you in the installation of your DNI and its additional modules with a detailed and pictorial installation manual. Our technical support is available by phone or email and offers distance and / or on-site training sessions.
Le DNI est conforme aux exigences réglementaires françaises et européennes. Breveté et testé par des organismes indépendants, le DNI déclenche une alarme dès qu’une fuite se déclare et avant d’avoir atteint les seuils réglementaires.
