What to do if ABB TPS48-F32 has charge air pressure too low?
- CCharles HubbardSep 3, 2025
If the charge air pressure is too low, there could be several reasons. The air receiver or the gas piping between the engine and the turbine might be leaking. A poorly adjusted injection system also can cause this issue, so correct it. The manometer display might be providing a wrong reading, so replace the manometer, or the line to the manometer might be leaking, so repair the leak. A contaminated filter silencer causing excessive loss of pressure can also be the reason, so clean it. In some cases, the compressor/turbine might be damaged, which requires contacting an ABB Turbocharging Service Station. High exhaust counterpressure can also cause low charge air pressure, so clean or repair the boiler or exhaust silencer.
