PET bottles are transported from a blower moulding machine or from a PET bottle de-palletizer to the bottle filling machine via air conveyors. The bottles are supported on a neck guide being part of a closed conduct conveying system pressurised by blowers installed alongside the conveyor track.

Often bottles get jammed as result of oscillations and/or at joining queuing bottles.
These problems are likely to occur even more frequently as the average empty-bottle weight decreases and bottles do become more slim lined.

These blockings cause manpower costs but mainly result in significant reductions of the overall line efficiency.

In 2004 CHP developed the unique DLAC system for the micro lubrication of the interface between the neck guide wear strip of the conduct and the underside of the bottle neck.

We recommend to apply the food industry approved Dry Lubricant DLT-333®.

We do apply the “direct contact” principle, so no brushes nor spraying systems, to achieve the highest lubrication efficiency and to exclude any risk of traces of lubricant entering the bottle.
