Norms and Standards for Compressors and Blowers in Biogas / Biomethane Plants
© 2011 Aerzener Maschinenfabrik GmbH Axel Cichon / May 2013
ATEX 94 / 9 EG
The blowers and compressors must be designed according the ATEX directives explosion protection Zone I and or Zone II
DVGW – Merkblatt G 440:Gas Treatment Systems:
Inside the piping system: Zone 1Outside (room): Zone 1 or Zone 2
Gas Injection Systems Inside the piping system: no ZoneOutside (room): Zone 1 or Zone 2
Acc. to the ATEX – directives the costumer has to issue an self – report to the explosion risks.
