Energy Industry - Nuclear
EVG fan systems are used both before and after the combustion process for conveying media in the energy industry.
Single or double inlet centrifugal fans made of steel or stainless steel can be implemented – as fresh air fans, for example. The axial fans, with fibre composite or stainless steel blades that can be adjusted when stationary, have many uses in the area of energy production. For the exhaust gas side, we also supply customised fans for up to 1,000 °C.
A special characteristic of EVG fan systems is the chemical resistance against corrosive components in the exhaust gas, such as HCl, SOx, HCl, HF, HBr, SOx, Cl, fluorine and CO. To protect against dust and other abrasive and sticky residues from the combustion process (soot, fibre residues or tar), we cover the impellers as well as the other housing parts that come into contact with the media with hard metals, tungsten carbide, Teflon, Ruby Red or similar.
With the right sealing systems, we can guarantee explosion protection for Zone 1 (21) and Zone 2 (22) in accordance with the ATEX Product Directive 2014/34/EU (formerly 94/9/EC). This also includes mechanical shaft seals, stuffing boxes or contact-free turbo labyrinth seals, also using sealing gas or return systems.

MAN wind-diesel power plant - Garabito, Costa Rica
In the world's largest wind-diesel power plant in Garabito, Costa Rica, which is operated with 11 MAN 18 V 48/60 diesel engines, the EVG hot gas fans prevent the backflow of aggressive sulphurous exhaust gases with temperatures of up to 450 °C into the engine by generating a permanent vacuum during and after operation of the 18,000 kW MAN engines. This reliably prevents internal corrosion in the engine in tropical climates and extends the maintenance intervals and service life of the engines.
Output range up to
- Volume flow: 2,000,000 m³/h
- Pressure: 5,000 Pa
- Temperature: 500 °C
