Cogeneration generator sets

Sustainable and efficient
cogeneration

We design custom cogeneration generator sets that maximise energy efficiency and thermal recovery. The high efficiency of cogeneration plants and generator sets lies in using the heat generated as a by-product of electricity production, thereby saving the system’s primary energy. By producing electricity and consuming it within the same facility, energy loss is avoided, achieving greater overall efficiency.

One system for several types of energy

Cogeneration means the simultaneous production of two or more types of energy in a single integrated process. Typically, electricity and heat are produced, although mechanical energy, heating and/or cooling are also possible. Cogeneration has applications in both industrial processes – heat- and electricity-intensive – and large buildings where the heat can be used for heating, cooling through absorption systems, or the supply of domestic hot water. It is common in shopping centres, hospitals, hotels, or administrative complexes.

Generator sets for interconnected cogeneration

We offer solutions for interconnected cogeneration, where generator sets operate in parallel with the power grid. These systems continuously optimise energy performance, providing maximum reliability and control. In industrial facilities or large buildings with high energy consumption, such systems guarantee efficiency, stability, and reduced operating costs.

Maximum performance

In a cogeneration process using a reciprocating internal combustion engine, fuel efficiency can exceed 80%, compared with the 35% efficiency obtained when used solely for mechanical energy (later converted into electricity). Cogeneration generators therefore significantly improve the overall performance of the installation.

Maximum efficiency

These systems, smaller compared to large combined cycles (gas and steam turbines with efficiencies around 65%), are increasingly being used. Their high efficiency and ability to meet basic energy needs (electricity, heating, and cooling) close to the point of consumption prevent the need for large installations and transmission losses, thus increasing overall efficiency.

We provide the right solution for every case, from complex emergency systems to industrial cogeneration generator sets. We always study your needs, design customised products, and deliver highly specialised after-sales support.

Development of a cogeneration set

In line with the energy needs of the client’s installations, each and every one of the main components of the equipment is calculated and sized: engine, alternator, heat exchanger for engine cooling, heat exchanger for engine exhaust gases, pumping systems, operation and handling controller, all with a view to maximising the energy efficiency of the fuel used.

Depending on the energy requirements, priority is given to electricity generation via the alternator, low-temperature heat generation from the engine or high-temperature heat generation from the exhaust gases.

Standard components of a cogeneration set:

Internal combustion engine (diesel, natural gas, LPG, biogas, biomethane, syngas, etc.)
Alternator to generate electric current
Liquid/liquid plate heat exchanger for energy utilisation of engine heat (low temperature)
Gas/liquid heat exchanger for energy recovery from exhaust gas heat (high temperature)
Control panel with integrated controller
Electric starter batteries
Fuel tank or mains-fed system
Supporting base of the set
Anti-vibration mounts
