Our solutions

Connected solutions dedicated to improving performance and reducing
the environmental impact of refrigeration installations.


The DNI - Intelligent Level Detector - is an expert system for detecting leaks, using an indirect measurement method.


Sentinelle is the web interface for managing and monitoring the DNI and its modules. Sentinelle compares, analyzes, advises and alerts.

Energy module

The energy module is an energy monitoring tool capable of measuring the actual consumption of an installation. It analyzes and compares performance and alerts in the event of energy drift or risk of breakdown.

HPF Module

The Floating HP (High Pressure) Module varies the condensing pressure as a function of the outside temperature in order to improve the energy performance of the installations.

An effective response to complex regulations

The European community strengthened regulations on fluorinated greenhouse gases in April 2014 with a new regulation (EU) No 517/2014. This new regulation commonly called "F-Gas" came into effect on January 1, 2015.

The objective of this regulation is to regulate the sale and use of refrigerants with a strong environmental impact. The progressive reduction of the quantities placed on the market and the reinforced leakage control of the installations are pillars of this European regulation.
