GasTOPS MetalSCAN is the most effective early detection & warning system of bearing status available today. GasTops MS4000 is designed for early detection and on-line debris monitoring of the progression of bearing condition in aero-derivative gas turbines. MS4000 can safe your engine and more likely, your entire production.

Early detection of bearing damage

Bearing damage cannot be actively prevented or predicted. The best option is to monitor bearing status and detect bearing damage at an early stage. GasTops MetalSCAN MS4000 is all about providing that reliable warning ahead of a potential event. One of the great benefits of this system is that you can choose to decrease power output and reduce the chance of engine damage. Another significant benefit is that it provides time to plan a scheduled engine stop.

GasTOPS MetalSCAN MS4000

GasTOPS MetalSCAN MS4000 bearing monitoring is the most advanced solution for early detection of bearing damage in aero-derivative gas turbines. MetalSCAN provides 24/7 online monitoring of the health status of all main bearings in your gas turbine.

MetalSCAN MS4000 has been developed to serve the energy market and stands out from other alert systems. MetalSCAN information allows operators to proactively plan the bearing replacement in order to minimize engine downtime and prevent secondary engine damage.

VBR Turbine Partners are the authorized GasTOPS partner

VBR Turbine Partners are the exclusive and authorized distributors for GasTOPS in Europe. MetalSCAN is provided as a dedicated service to monitor the gas turbine’s bearing condition. In conjunction with VBR’s Remote Monitoring and Diagnostics system DECIDE we are able to identify bearing condition against the back ground of all engine variables and signals. The combined input of information sources and our modelling software enable us to identify potential root causes faster. The condition of gas turbines is monitored and analysed continuously to reduce failure risks.

Simple solid state and reliable design

GasTops MetalSCAN has no moving parts. It has been designed for heavy industrial use and to withstand high temperatures year in and year out. MetalSCAN monitors lube oil debris at a particle level and is able to detect bearing damage in a very early stage. It uses a through-flow inductive sensor that is installed in-line within the turbine lubrication oil system. The sensor is capable of detecting and categorizing ferrous and non-ferrous particles by size and type. MetalSCAN has been designed to be maintenance free and it does not indicate ‘false positives’.

Early warning prevents secondary damage

As soon as MetalSCAN detects the smallest amount of bearing wear particles it generates a warning signal. From this moment on MetalSCAN will provide real time trending information about the development of the damage. This information can be monitored by operators themselves. VBR can provide assistance analysing the data and advise on maintenance preparation and planning. With MetalSCAN installed as part of our solution DECIDE Remote Maintenance Support VBR is able to analyse & interpret the data in the broader context of other engine-specific data enabeling more specific recommendations to be identified. With MetalsSCAN operators can proactively identify & plan the necessary maintenance actions scheduling an outage for repair.

The most effective solution

MetalSCAN provides a second warning before the risk of secondary damage becomes critical. As a result the engine can be brought to a controlled stop. Based on MetalScan data maintenance can be planned and the issues can be addressed before a second warning comes up. In general this second warning is a reliable indication that secondary damage is imminent. Experience has taught the second warning of the GasTops system comes before warnings from any other monitoring system. When compared to systems like vibration monitoring, temperature measurement, chip detectors or any other means GasTops MetalScan beats them all. Other warning systems do not specify the root cause of the alarm. This makes MetalSCAN far superior in early detection of bearing damage.


The MetalSCAN benefits are:
Proactively plan a bearing exchange;
Prevention of secondary damage;
Planning & minimizing engine downtime;
Reduce costs and save money;
Peace of mind.
