Presenting at Chillventa 2026:
SELPRO | From analogue control to digital EC fan management
Solutions designed to simplify the installation, configuration, diagnostics and maintenance of EC fan systems in HVAC/R applications, from analogue 0–10 V control to digital Modbus communication.
Visit SELPRO at
Hall 7 - Stand 7-412
From 13 to 15 October in Nuremberg, SELPRO will demonstrate its solutions for controlling and managing EC fans in HVAC/R systems.
Chillventa 2026 spotlight
From the simplicity of analogue signals to the capabilities of Modbus
At Chillventa, SELPRO will demonstrate how EC fan management can evolve without making installation more complicated, while enabling more advanced control, diagnostics and monitoring functions.
The solutions cover everything from 0–10 V analogue signal distribution to Modbus RS-485 communication, supporting both new equipment designs and retrofit projects involving existing systems.
Four solutions for different application requirements
At Chillventa, visitors will be able to see four SELPRO solutions for managing ventilation systems equipped with EC motors. Detailed product information is available for each solution.
Plug & Play digitalisation
MODULO
Brings digital EC motor management to existing systems, enabling Modbus communication without unnecessary configuration complexity or the need to replace the main controller.
Each fan can be managed individually, providing access to operating data, diagnostics and information that supports system monitoring and maintenance.
Application-specific control
ECpro
A specialised controller for fan-assisted heat exchangers equipped with EC motors, developed for applications such as condensers, dry coolers and gas coolers.
Coordinates fan control and operation through application-specific control logic, simplifying the management of the complete fan system.
Multifunction digital control panel
ECD
A multifunction digital master control panel designed for single-phase and three-phase EC fan motors.
A compact solution that brings EC fan control and management together, simplifying the design and organisation of the unit's electrical control system.
Advanced analogue control
EDDY
A device designed for adaptive management of electronic equipment connected through 0–10 V and PWM analogue control networks.
Enables control signals to be managed and adapted, facilitating the integration of electronic devices into both new and existing installations.
Digitalisation spotlight
MODULO: digital management without additional system complexity
MODULO introduces digital communication capabilities into EC fan management while keeping installation and retrofit operations straightforward.
Plug & Play
Designed to simplify EC fan configuration and commissioning.
Data and diagnostics
Access to individual motor operating data to support monitoring and fault diagnostics.
Retrofit
Enables existing systems to be upgraded to digital EC fan management.
From field devices to system supervision
More operating data for advanced EC fan management
Digital communication goes beyond basic fan speed control, providing access to valuable information about EC motor operation.
The available data can support system supervision, diagnostics and maintenance, enabling more informed management of the ventilation system.
