Digital Generator Controls

HEINZMANN has a wide range of products for controlling generators. The multi-functional, digital and cost-efficient XIOSGenSet governor offers a wide range of solutions for controlling generators as well as protection and monitoring functions. It assumes sole, central responsibility for controlling the entire genset system.
The Si-TEC Xtend generator governor is a specialist for controlling steam turbines. Viking35 offers extensive configuration options and is combined with hydraulic actuators from REGULATEURS EUROPA. The tried-and-tested THESEUS governor is suitable for generators operated as islands or in parallel. As an option, it can be combined with HEINZMANN speed governors.

ICENI I/O Modules

The I/O modules in the ICENI range can be used for communicating with a PC or PLC devices, or for expanding the RE Viking35 ECU. The modules are mounted on standardised rails and have been designed with value for money in mind. They can be easily programmed using a touchscreen, without the need for support from a programmer or laptop. ICENI has been designed for high-performance operation under the high temperatures in the engine, but is equally suitable for other applications – whether as an extension of RE control and monitoring solutions or as a product for other original equipment manufacturers.
