Maximum power, compact design: Gefran presents GRC, the new intelligent power controllers for industrial electric heating

In response to these requirements, Gefran presents GRC, the new series of smart and compact power controllers. Designed to offer high performance in industrial electric heating, they combine power, precision and advanced connectivity via the main communication protocols.

GRCs introduce new standards of scalability in electric heater control. The series is modular and available in single-phase, two-phase and three-phase configurations, with currents from 25 A to 150 A, thus adapting to linear and non-linear resistive loads for high temperatures. Their compact size, combined with integrated fuses, allows for optimisation of space in electrical panels, facilitating the design of more compact systems.

Accuracy in current and voltage readings is another strong point. Thanks to integrated feedback algorithms, GRCs maintain stable power and current even in the presence of electrical disturbances, which is essential in critical processes such as semiconductor production or flat glass processing.

Advanced connectivity completes the series’ features. All devices are native Ethernet and offer two physical ports for immediate access to data, without the need for additional cards or gateways. The integrated WebServer allows complete control of diagnostics and alarms through easy access via browser from any device and remotely. In addition, the front LCD display allows real-time monitoring of system performance, enabling timely intervention in the event of anomalies and optimising operational continuity.

With the dedicated Gefran GF_eXpress software, installation, configuration and maintenance are even faster and more intuitive. Thanks to a smart interface, designed to ensure intuitive diagnostics and support efficient and customisable production processes.

“With GRC, Gefran’s GRx platform is enhanced with compact and functional devices designed to meet complex application requirements. The expansion of the available current range, already planned in the launch roadmap, demonstrates Gefran’s commitment to creating flexible and scalable solutions,” said Guido Zini, Power Controllers & SSR Product Manager at Gefran. “Innovation continues: with the expansion of the range planned for February 2026, advanced features in terms of digitization, efficiency, and sustainability will be introduced.”
