KRONOS 10 mechanically controlled |
|
Simple mechanical air fuel ratio control system consisting of a throttle valve, a Venturi based gas/air mixer and a mechanical gas main adjusting screw. |
Good solution for all sizes of engines from 25 kW to 3 MW where precise control of emissions is not required. | |
| KRONOS 20
electronically controlled |
|
|
For Lambda 1 and lean operation up to 1 MW and for higher emission quality requirements. |
|
| Option with Annular Gap Gas Mixer |
|
Electronically controlled AFR control system. All KRONOS 20 functions integrated in annular gap gas mixer. | ||
| KRONOS 30 M
full authority |
|
Full authority system including speed/load control. Flexible modular concept can be extended to accommodate applications with larger variations in gas, engine and ambient parameters. |
For multi-gas and high gas quality or lambda fluctuations with power range 200 kW to 3 MW. | Leaflet KRONOS Manual KRONOS 30 |
| KRONOS 40
injection based |
|
Speed/load control system for gas engines with gas injection valves controlled by solenoid valves. Individual cylinder injection and exhaust gas temperature sensing, which makes precise gas metering possible. |
The system can handle cylinder outputs from 100 to 600 kW and up to 20 cylinders. Basic system used on injection engines in leanburn mode.
