We provide you with reliable and efficient generator sets that comply with EU Stage V emission reduction regulations. We develop the latest technology for cleaner energy.
Stage V generator sets
Versatile, efficient, and sustainable
New technology adapted to your needs and those of the environment
In compliance with emissions regulations, the range of Stage V engines incorporates the most advanced technology to provide cleaner and totally reliable energy. A job carried out from our Distributed Energy Technology Centre (DETC), the R&D+i space from where we conceive innovative and custom-designed generator sets.
What is STAGE V?
For years, the European Union has prescribed limits for emissions of polluting gases and particles. With the aim of improving air quality, in 2016 the European Parliament and the European Council tightened the restrictions on internal combustion engines installed in non-road mobile machinery, a categorisation which include generator sets.
The European Regulation for Non-Road Mobile Machinery Emissions (NRMM) 2016/1628/CE or Stage V regulation, came into force on 1st January 2019, forcing the implementation of an adequate exhaust gas aftertreatment strategy to control and measure engine emissions.

- Aftertreatment systems integrated into the bench.
- Integrated control panel.
What are the features of STAGE V equipment?
Unlike generator sets exempt from complying with regulations, such as emergency stationary installations, Stage V equipment incorporates all the technical solutions required to contain emission levels.
DOC (Diesel Oxidation Catalyst)
Diesel oxidation catalyst specifically designed to reduce carbon monoxide (CO), hydrocarbons (HC) and particulate matter (PM) emissions by converting harmful components in exhaust gases to carbon dioxide (CO2) and water (H2O).
DPF (Diesel Particulate Filter)
Particulate filter that retains polluting particles present in exhaust gases commonly known as soot.
SCR (Selective Catalytic Reduction)
Selective catalytic reduction process that optimises combustion processes through the chemical reduction of nitrogen oxides (NOx) present in exhaust gases.
EGR (Exhaust gas recirculation)
Recirculation or redirection of part of the exhaust gases in order to reduce the nitrogen oxide (NOx) content of the exhaust gases. This system is often used in combination with DOC or DPF aftertreatment systems therefore reducing particulate emissions.
In addition, modifications are required in the equipment designs that allow the integration of these technical solutions, ensuring correct operation. These are some of the new requirements:
- Guarantee adequate ventilation in strategic areas.
- Complete redesign of the exhaust gas outlet system to integrate the new systems (DOC-DPF-SCR).
- More demanding thermal insulation to maintain the temperature of the exhaust gases at adequate values.
- The cabin design, under the premise of a compact product that allows economy of transport, becomes more complex as it is subject to more restrictions.
Regarding the electrical area, the control system must maintain the combustion engine at a minimum load of approximately 25% of the nominal power to ensure that the exhaust gas temperature is always at the minimum value that allows the correct operation of the exhaust gas aftertreatment systems. In order to maintain this minimum load it is very important to:
- Install a load bank at the power output of the generator. This load bank is made up of electrical resistances automatically switched by the generator control system according to the requirements of the system.
- For safety reasons, the generator must also have a circuit-breaker switch so that the loads to be fed from the generator can be isolated in the event of a failure in the exhaust gas aftertreatment system.
In order to know the status of the gas aftertreatment system at all times, communication between the engine electronics and the generator control unit must be perfect. The reason is simple: proper operation of the entire system depends on this communication. The engine needs the external data that the control unit transmits to it, and vice versa. In this way, the engine will always work in the correct way to comply with the emission restrictions, even when the installation that feeds the generator does not need it, and so it is working in isolation.
