TURBO TEST DUO
Combined high-speed core balancing machine and dynamic turbocharger flow bench
Turbo Test Duo combines a high-speed core balancing machine and a turbocharger calibration machine also known as a flow bench. The machine supports the turbochargers of passenger cars, light-duty trucks and heavy-duty trucks.
HIGH-SPEED CORE BALANCING MACHINE
| DESCRIERE | PARAMETRU |

TURBOCHARGER FLOW BENCH
| DESCRIERE | PARAMETRU |
|---|---|
| Maximum turbine inlet air pressure | 250 kPa |
| Air mass flow measurement accuracy | +/- 1 kg/h |
| Maximum mass air flow that can be measured | 450 kg/h at 1 bar turbine inlet pressure at 25°C air injection temperature |
| Maximum volume air flow that can be measured | 380 m³/h at a turbine inlet pressure of 1 bar and an inlet air temperature of 25°C |
| Turbocharger position | Like in a car with an oil drain directed downward to achieve the highest measurement accuracy |
Turbo Test Duo Pro
In addition to the high-speed balancing feature, the machine enables you to calibrate turbochargers by the adjustment of the air mass flow of the turbine section. The measurement can be conducted in a static or dynamic mode. The dynamic mode enables you to measure the rotational speed of turbocharger. As a result it is possible to determine turbocharger’s technical condition and its more precise adjustment than in case of the static mode.
Turbo Test Duo Expert
This model of the machine enables you to restore 100% turbocharger’s performance by its calibration according to turbocharger’s pressure ratio measured under load at high speeds. The pressure ratio is turbocharger’s outlet parameter that defines its performance. It enables the precise determination of turbocharger’s technical condition and its most accurate calibration.
