Flawless condition
The turbocharger must only be used when it is in a technically flawless
condition and operated in compliance with its intended use.
ABB Turbo Systems excludes any liability for damage resulting from un-
authorized modifications to the turbocharger or improper operation.
ABB turbochargers can tolerate a deflagration with a transient pressure
increase of 12 bar.
ABB Turbo Systems recommends subjecting the turbocharger to a visual
inspection after a deflagration event. As part of the inspection, the posi-
tion of the turbine casing and the position of the compressor casing to
the bearing casing must be checked, and the bearing casing must be ex-
amined to see if it has shifted in relation to the bracket. A crack inspec-
tion of the casings and the bellows is also recommended. The nearest
ABB Turbocharging Service Station should be instructed to carry out this
inspection and assessment.
