Gefran

Gefran is an Italian technology company specializing in automation equipment, industrial sensors, drives, and HMI systems for the manufacturing industry. The company, founded in 1969 in Provaglio d'Iseo, Italy, develops and produces a broad portfolio of products for industrial process control and machine configuration. At Verkopershulp.nl, more than 749 Gefran products are available for direct delivery.

The Gefran range includes PID temperature controllers and process controllers, pressure transducers and pressure transmitters, position sensors and linear positioning systems (LVDT sensors), power drives (DC and AC) for electric motors, thyristor-controlled power regulators, HMI operator panels and graphic displays, and servo drives for precise positioning.

Gefran is known in the plastics processing industry for its components specifically designed for injection molding machines and extruders. The WRG series pressure transmitters, designed for measuring melt and injection pressure in plastic processing machines, have become the industry standard. These sensors withstand temperatures up to 350 degrees Celsius and pressures up to 2500 bar and offer exceptional accuracy in the most demanding process conditions.

The Gefran GFX series HMI graphic displays and touchscreens provide operators with an intuitive interface for machine operation and process monitoring. They are available in screen sizes from 4.3 inches to 15 inches and support communication via PROFIBUS, CANopen, EtherNet/IP, and Modbus. The robust IP65/IP66 housings make them suitable for installation in dusty and wet industrial environments.

At Verkopershulp.nl, you will find the complete Gefran range for direct ordering. Our technical team advises you on the correct product specification and configuration for your industrial automation application.

Gefran has further expanded its technology expertise through the acquisition of Siei Drives, a manufacturer of AC servo drives and power converters. This has enabled Gefran to offer a complete automation portfolio, from sensor to drive, including the required process control and HMI interface. For plastic injection molding machines, the combination of Gefran pressure transmitters, temperature controllers, and servo systems has become the market standard.

The Gefran Siei ADV series drives and GFD series servo drives offer state-of-the-art motor control with advanced field-oriented control (FOC) and synchronous motor capabilities. Gefran supports its customers with extensive technical documentation, online parameterization tools, and a professional support team for drive and automation applications. At Verkopershulp.nl, you benefit from our knowledge of the Gefran product program for fast advice and delivery of the right components.

History

Gefran was founded in 1969 in Provaglio d'Iseo, Brescia, Italy. The company started as a manufacturer of industrial temperature controllers and grew rapidly through its focus on the Italian plastics processing industry. In the 1980s, Gefran expanded its range to pressure transmitters for plastic machines and positioning systems. The introduction of power drives and HMI systems in the 1990s completed the automation portfolio. Today, Gefran has more than 1,000 employees and offices in more than 40 countries, with production facilities in Italy, Germany, and the USA. Gefran has systematically expanded its international presence through acquisitions, including Siei Electric for drive technology and ABO Wind for wind energy electronic controls. Today, Gefran is listed on Euronext Milan and operates with offices in more than 40 countries, with production facilities in Italy, Germany, India, and the USA serving global customers.
