A complete solution for the monitoring, regulation, and performance management of HVAC systems and district heating networks

User-friendly Remote Terminal Units

Dedicated to HVAC network management, SOFREL’s remote controllers integrate communication modems and rely on their specialized ‘Heating’ functions to monitor sites 24/7, alert in case of anomalies, manage, and manage and automate technical facilities.

With SOFREL telemetry devices, contract operators can remotely control their HVAC facilities, act on motors, pumps, or valves, and even automate their facilities’ processes.


IoT Sensors and LoRaWAN Gateway

We offer LoRaWAN IoT sensors and probes to monitor CO2, temperature and humidity levels in industrial, public, collective, and tertiary buildings.
A LoRaWAN IoT gateway enables the creation of a private network for seamless communication with S4TH remote controllers.


SOFREL LX SCADA HVAC

Integrated Platforms for the Centralization and Supervision of HVAC Systems

Our LX SCADA and LX CONNECT solutions are dedicated to the centralization and supervision of HVAC system networks.

The LX SCADA supervisor ensures efficient and optimized management through remote monitoring of equipment, operational data analysis, and real-time alert management.

The LX CONNECT platform centralizes the management of equipment and users, orchestrates cybersecurity, and provides a 360° view of the deployed fleet.

Together, these solutions offer smooth, secure, and intuitive management for the remote operation of Heating, Ventilation, and Air Conditioning systems.


Centralization, Gateways, and Communication Servers

The management of HVAC networks relies on the centralization of data from various installations. Our data communication solutions link on-site equipment to supervisory platforms.

We offer a complete ecosystem of gateways and communication servers, designed to ensure the reliability and security of information exchanges.
