Operating limits and replacement intervals The recommended replacement intervals and the corresponding operating limits in chapter 3 are jointly defined with the enginebuilder. This information is specific to the product. Non-observance of the recommended replacement intervals and the operating limits increases the risk of unpre- dictable component failures.

1 Safety / 1.6 Deflagration on gas engines Deflagration on gas engines Low-pressure stages from ABB Turbo Systems can tolerate a deflagration with a transient pressure increase of 12 bar (guideline value). High-pressure stages from ABB Turbo Systems can tolerate a deflagration with a transient pressure increase of 15 bar (guideline value).
The locations of the rating plates are defined in the Operation Manual, Chapter 4 Product description. Periodic check of the pressure vessels The pressure vessels used by ABB Turbocharging, such as those for wet or dry cleaning, are so-called "simple pressure vessels". ¡...

Non-insulated low-pressure and high-pressure stages can cause serious in- juries to personnel (burns). ABB Turbo Systems supplies the low-pressure and high-pressure stage with or without insulation in accordance with the purchase order received from the enginebuilder. If supply is without insulation, the enginebuilder is re-...

Do not clean the compressors of the different high and low-pressure stages at the same time, but one after the other. On V-engines with several low-pressure and/or high-pressure stages per engine, ABB Turbo Systems recommends the parallel cleaning of the LP compressors as well as the parallel cleaning of the HP compressors.
