Turbo Technics VTR opens doors for remanufacturing industry

The brand-new Turbo Technics Vane-Flow Test Rig (VTR), launched today at the Automechanika show, is set to open up a whole new range of opportunities for the turbocharger remanufacturing market. The VTR is the first commercially available aftermarket turbocharger variable geometry calibration system and will allow the industry for the first time to calibrate actuation systems and as a result, offer remanufactured variable geometry turbochargers to the end user at significantly lower costs than a brand new item.
Developed using the same experience and expertise that led to the company's range of Vibration Sorting Rigs (VSRs) becoming the global industry standard for dynamically balancing turbochargers, the VTR is aimed at every size of turbocharger remanufacturer. The VTR will allow the recalibration of any form of variable geometry system and on launch, will handle both pressure and vacuum activation while an upgrade to allow recalibration of electronically controlled systems is currently under development.
 
The VTR allows the remanufacturer to set two crucial parameters on variable geometry systems; the minimum opening of the vanes and the operating range of the vane movement. The turbocharger under test is mounted to the VTR and the on-board computer system controls the airflow and measurement through the turbine housing and compares this against the data stored for that turbocharger model.
 
When testing the minimum vane opening, the operator adjusts the unit's mechanical stop until the VTR displays the correct airflow for the minimum opening condition. The machine also carries out a full movement operation on the vane system, measuring airflow throughout the range and comparing it with the data stored in the on-board database, and has built-in ambient temperature and pressure compensation. The VTR will also allow accurate calibration of wastegate actuators, ensuring optimum performance for all turbochargers.
 
Each Turbo Technics VTR will be supplied with the latest version of the Turbo Technics database of flowrates for a range of turbochargers and this is continually updated, firstly at Turbo Technics and then on to VTR users. The company anticipates that a workflow rate of approximately 60 turbochargers per day could be calibrated using the VTR.
 
Commenting on the news, Turbo Technics Managing Director Geoff Kershaw said; "The advent of variable geometry turbochargers is fantastic news for the driver; these systems offer the best of both worlds, by ensuring that gas speed within the exhaust turbine is as high as possible at low engine speeds, minimising the effect of turbo lag but allowing the turbo to operate at its optimum at higher engine speeds.
 
"However, the disadvantage has been that if, for any reason, there is a problem with a turbocharger using variable geometry, the only solution is a brand new unit direct from the manufacturer, at significant cost to the end user. This is because to successfully remanufacture this type of turbo, it is essential that it is flow-tested and this simply has not been possible until now, as no-one other than the manufactures had the technology.
 
"The remanufacturing industry has been demanding a reliable and consistent way to calibrate variable geometry turbochargers for some time and we have developed the Vane-flow Test Rig as a result of that demand. We feel that it is the machine the turbocharger industry has been waiting for and are very excited about it and its launch at Automechanika."
 
The Turbo Technics VTR was unveiled at 10.00am on Tuesday 16th September on the company's stand at Automechanika in Frankfurt, stand E67 in Hall 5.1. The VTR debuted alongside the latest version in the company's respected VSR range, the Mk5P, designed to allow dynamic balancing of turbochargers for commercial applications.
