Many repair technicians know the problem: A used turbocharger is reconditioned with genuine parts, then balanced with the highest possible accuracy - first for TBcomfort and then for TBcore or TBsonio, and directly following the installation there already is the first error message: Either the boost pressure is too high or too low, the motor has no power, or it even switches to the emergency program. These errors frequent appear in reconditioned turbochargers if they are installed without calibrating the variable turbine geometry. In most cases, the reason is that permissible tolerances are exceeded which leads to engine malfunction. Resolving the issue not only takes a lot of time but is also costly: Disassembly, shipping, calibration, and return to the customer can quickly increase costs and reduce profit.

With the VISCOM Flow Bench, reconditioned VNT/VTG turbochargers can be calibrated with precision easily and quickly in just minutes so that they reliably meet the manufacturer's specifications. The test is quick and straightforward: Simply clamp the turbocharger into the machine with the correct adapter. Thanks to the magnetic adapter, this can be done quickly and without any tools. Next, block the turbocharger on the compressor wheel side to prevent it from turning inadvertently and connect the pneumatic or electric boost pressure actuator. After entering the turbocharger model on the touchscreen, the measurement run is started. After a few seconds, the measurement is complete and you will see whether the charger is within the manufacturer tolerance. If it is outside the tolerance, the turbocharger can be recalibrated directly without removement - and this can be done very comfortably while the measurement is running.
