Operation Manual / A130-H.. - A140-H..
3 Introduction
For use on pre-mix gas engines with ignitable propellents in the gas control system, the engi-
nebuilder must implement appropriate safety measures for explosion protection [3] (such as
flame barriers in the inlet system, for example) to assure that the turbocharger will only be
exposed to a transient pressure increase up to a maximum of 12 bar as the consequence of
any deflagration.
The turbocharger supplies the engine with the air volume or air/gas mixture and the associa-
ted charging pressure required for operation.
The specific operating limits of the turbocharger were determined on the basis of information
from the enginebuilder about the intended use. These data are given on the rating plate.
ABB Turbo Systems accepts no liability and rejects all warranty claims for any non-intended
uses.
