State of the art
The turbocharger is designed and manufactured according to the state of the art and is safe
to operate.
Perfect condition
The turbocharger must only be used when it is in a technically flawless condition and oper-
ated in compliance with its intended use.
Turbo Systems excludes any liability for damage resulting from unauthorized modifications
to the turbocharger or improper operation.
2.6 Deflagration on gas engines
ABB turbochargers can tolerate a deflagration with a transient pressure increase of 12bar.
After a deflagration event ABB recommends verifying the following points on the turbochar-
ger:
¡ Position of the turbine and compressor casings to the bearing casing
¡ Shifting of the bearing casing in relation to the bracket
¡ Cracks in casings
If during external inspection anomalies are found or if a particularly strong deflagration
event has taken place, it is also recommended to check the bearings of the turbochargers
before the next start. A Turbo Systems service station should be instructed to carry out this
inspection.
