automatic – includes an automatic control unit that starts the genset in case of mains failure (it can be started manually too), main circuit breaker, differential protection and all auxiliary controls and alarms, button for emergency stop, changeover genset / mains (ats) on request.

synchronization – automatic control cabinet for synchronization more generating sets and / or main electricity network and parallel operation. additional and special control and switching cabinets for genset on demand.

Standard housing

Standard sound insulated housing, suitable for outdoor and indoor application. It is equipped with four doors with locks for easy maintenance and servicing of the genset. Fixed louvers at the entrance and exit for engine cooling, exterior or interior point for fi lling the fuel tank. All housings are powder coated with primer and cover color (standard color RAL 7035, other colors on request). Standard noise level is 72 ± 3 dB at a distance of 7 m (lower noise levels on request). Possibility of special
housing on request.

Container housing

Container housing for bigger genset, low noise levels and the specific working conditions of generating sets. Container housing standard lengths of 20‘ (6 m) and 40’ (12 m). Fixed louvers at the entrance and exit for engine cooling, exterior or interior point for fi lling the fuel tank. Container housings are painted with primer and cover color. Suitable for outdoor and indoor installation. Possibility of special container housing on request.

Manual cotrol cabinet KO-R MRS

Manual control cabinet can be mounted on genset or delivered separately. It includes the entire control and management of the engine and generator, and remote start of the genset. By pressing a button (key) genset starts and stops (also from a remote location). Genset can also start and stop by signals to be obtained from the outside (remote start).

It consists of a metal electrical cabinet, manual control panel of the genset SMC10, the generator protection circuit breaker, emergency stop key and fuses. The cabinet is ready to connect the power cable for consumers on a copper strip or staples.

Automatic control cabinet KO-A AMF

Automatic control cabinet can be mounted on genset or delivered separately. It includes the entire control and management of the engine and generator, and remote start of the genset. It allows the automatic start of the genset at main power network failure and stop on its return. Automatic control cabinet can operate in the following modes: AUTO / MANUAL / TEST / OFF. Genset management is provided by the keys with mechanical feedback and a large graphic display. Management and control can be run also through remote computer (PC). It is possible to connect generating sets in the network.

It consists of a metal electrical cabinet, automatic control panell of the genset SAC35, the generator safety switch, emergency stop key and fuses. The cabinet is ready to connect the cable of the consumers on a copper strip or staples.

Paralel synchonization control cabinet KO-P AMF

Automatic sync control cabinet can be mounted on genset or separately. It includes the entire control and management of the engine and generator, and remote start of the genset. It enables the automatic start of the genset when main power network fails and stops on its return. It also enables synchronization of network and genset and parallel operation of the genset and main electric network. The parallel synchronization control cabinet can also cover electrical spikes. In  case that the designated facility needs additional electricity, genset in parallel operation can add this deficit to the main electrical grid. Genset can also cover a specific part of the power so that is no need  to be collected from the main electricity network and pay credits at a higher rate.  Genset performs uninterrupted switching between the network and genset. It is also possible for uninterrupted test of the genset at full or partial load. Genset management is possible by keys with mechanical feedback and a large graphical display. Management and control can be run also through remote computer (PC). It is possible to connect generating sets in the network.
