Cleaning Results

Photographic Analysis

These photos of a pipe's inner surface before and after cleaning with ptcsystem distinctly show its outstanding efficiency. Metal shavings and other impurities are clearly visible before cleaning.

Optical Analysis of Residual Contamination by Means of Membrane Filter.

This analysis compares the amounts of residual contamination rinsed from three ½-inch (DN12) pieces of hydraulic hose, each cut on both ends. The first piece of hose was not cleaned before rinsing, the second blown out with condensed air and the third cleaned with ptcsystem.

The particles dislodged during the respective rinsings are filtered from the mediums using 8 µm membrane filters. The amount of residual contamination collected from each hose and subsequently caught in the respective filters is then optically evaluated.

The following photos of the membrane filters leave no room for doubt concerning ptcsystem's efficiency: The filter from the untreated hose shows heavy contamination, mainly rubber grit and shavings. Blowing the hose out with compressed air proves insufficient as well, as distinct contamination is still apparent. The filter from the hose cleaned with ptcsystem, on the other hand, shows only minimal residue.

Gravimetric Analysis of Residual Contamination

The gravimetric analysis expands on the optical evaluation of the membrane filters resulting from the analysis described above. It employs highly sensitive scales to weigh the debris particles caught in the membranes, thus determining the weight of each component's residual contamination before rinsing. The following diagram shows a gravimetric analysis carried out by HYDAC International on a DN12 hydraulic hose cut on both ends. Each hose was cleaned with different projectile types.
