The modular characteristics and mechanics of the MDI engine lends itself to be extremely adaptive and this adaptability has been harnessed to employ the engine to generate electricity.
- For an Emergency Electricity Generator (EEG) the mono-energy engine is utilised. In the event of power failure the unit is actuated automatically, using only the compressed air to run the engine that drives the generator. Operational range is directly related to the size the air tanks. When the power returns to normal, the engine runs in compressor "mode" to refill the tanks. Starter battery or fuel is not required, therefore the maintenance is reduced to the absolute minimum.
- For Electricity Production Generator (EPG) the engine is operated by continuous external combustion (in a similar manner to the dual-energy CATs engines) using the least expensive fossil or bio-fuel, LPG or gas. The unit continuously compresses the air that runs the engine.
A large range of power levels :

A wide range of power levels can be provided because of the modular nature of the MDI Engine, both mechanical and electrical.
- The MDI Engine can be mechanically coupled horizontally to form 4 and 68 cylinders, allowing incremental power to be produced varying in range from 12 kilowatts to 60 kilowatts. With this outstanding mechanical modularity, manufacturing process can be industrially rationalized by producing only one type of twin-cylinder engine.
- Additionally, the engines can be electrically coupled in racks, the whole unit being controlled by an energy plant able to produce several hundred kilowatts. With this particular arrangement, the engines can be started sequentially, according to the power requirement.
This versatility can be deployed to provide power for an individual requirement or for a wider application. In the rack structure has a tremendous advantage that the maintenance or repairs can be carried out without interrupting electricity production.
Co-generator units :
Furthermore, because of the inherent design of the MDI engines, they can generate both heat and cold as the principle is based on compression and expansion of a gas (in this case air), calories can simply be recovered where they are produced. The modularity is similar to that of the generator units, thus allowing individual or network applications. For example, in heating or air-conditioning premises.
