The DNI
The DNI - Intelligent Level Detector - is an expert system for detecting leaks, using an indirect measurement method.
Sentinelle
Sentinelle is the web interface of the DNI and its modules. Remote monitoring, data analysis, alerts and technical advice make it a powerful technical tool.
The Energy Module
the Energy Module measures the energy consumption of a refrigeration installation and thus calculates its actual Coefficient of Performance (COP). It also alerts in the event of energy drift or risk of compressor failure.
The Floating HP Module
The Floating HP (High Pressure) Module adapts to the outside temperature and acts directly on the installation in order to save energy.
Our customers testify
They trusted Matelex for the surveillance of their installations,
here are their testimonies :
« We have installed several DNIs on mass distribution facilities and we are very satisfied with the product, it perfectly meets our needs and those of our customers. »

« Within my agency we have equipped ten installations with the DNI system. We are much easier to detect even small refrigerant leaks on our large installations. The equipment is simple to install, the touch screens are intuitive and easy to use for the customer and the technician. »

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.
