Marani offers units Marani ORCwhich are capable of generating electricity in the power range from 10 kWe to 500 kWe and heat-driven jet cooling systems reaching up to 200 kW of cooling capacity.
Marani gyms ORC mogą współpracować z silnikiem spalinowym zasilanym gazem ziemnym kopalnianym pochodzącym odmetanowanie kopalń i wyrobisk korytarzowych, który pracuje jako silnik napędowy dla generatora elektrycznego lub sprężarki powietrza. Spaliny z silnika gazowego, które są nośnikiem energii cieplnej w tym procesie i zarazem odpadem mogą zostać wykorzystane jako heat source for ORC plant. Marani offers comprehensive solutions for the recovery of heat from flue gases using high-temperature installations operating with an intermediate loop of thermal oil. A configuration with direct evaporation of the working medium is also possible.
The heat stream received is converted into electricity, either fed back into the grid or consumed for own use. An additional advantage is the possibility of cogeneration operation and the additional production of useful heat.
Zastosowanie technologii MARANI ORC w odzysku ciepła odpadowego ze spalin silnika gazowego increases the energy efficiency of the system and makes it possible to reap additional profits from electricity generation.
The exhaust gas of the gas engine can also be used to drive MARANI refrigeration systems. In the case of a high-temperature heat source, it is possible to obtain a higher COP of cooling systems than in the case of low-temperature sources. It is also possible to utilise the low-temperature heat from the oil system of the aforementioned gas engines, which makes it possible to use both MARANI solutions working together with a single heat source.
The cooling capacity can be used for standard cooling with chilled medium parameters of 6oC/12oC or high-temperature cooling, e.g. 16oC/19oC. This temperature can be customised, which can also have a positive impact on the performance of the chiller.
The use of the above technology also increases the efficiency of the plant by utilising waste heat, as well as enabling additional savings by, for example, replacing traditional energy-intensive air conditioning systems.
ORC advantages:
- additional electricity production - without burning additional fuel
- reduction in CO2 emissions
- increasing energy efficiency indicators
- no interference with the technological process

- can be installed in container and mobile housing
Advantages of jet cooling systems:
- providing cooling capacity, reducing the electricity consumption of standard cooling systems
- reduction in CO2 emissions
- increasing energy efficiency indicators
- no interference with the technological process
- wide adaptability of parameters of cooled medium
- high COP of the cooling system achievable both by utilising waste heat from the hot engine exhaust gases and from the gas engine cooling oil
- can be installed in container and mobile housing
