With measurements every two to three seconds, the DNI conducts full leak detection, continuously. Tested on a panel of well-adjusted positive and negative installations in superstores and hypermarkets, the DNI permitted a 79% saving in refrigerant compared with traditional detection (Ademe report of February 2011), with a return on investment of less than a year.
In the event of a leak, an alert is triggered and the operator is warned by local alarm and email so that action can be taken as quickly as possible.
Installing a DNI reduces the frequency of leak detection (according to EU Regulation no. 517/2014 Art.4).
The energy module of the DNI calcules the energy consumption of the installation and calculates the actual COP.
The floating HP module saves energy.
Sentinelle, the online interface for DNI management, is a complete monitoring and traceability tool for refrigeration installations.
