To ensure its distinctive square plastic bottles are properly dried prior to labeling, Highland Spring has installed a Secomak PowerStrip airknife drying system at its Perthshire bottling plant.

Because the blow moulded bottles are filled with cold Highland Spring Natural Mineral Water directly from the spring, condensation often forms on the bottles' surface. This has to be effectively moved prior to labeling.

After looking at a number of options, Highland Spring opted for a Secomak PowerStrip drying system, consisting of two customised air knives within an enclosed acoustic cabinet. Because the conveyor moves at high speeds it is neccesary to expose as much of the bottles' surface to the drying effect in as short a time as possible. The existing conveyor guide rails obstructed the air flow, so they were removed and replaced with the Secomak special container guidance system.
