All of the portable units now come standard with complete coil height adjust readout controller at no additional charge. The height adjust records the bottle height of each production run, allowing you to track the analog number of each bottle size. When you are sealing multiple height bottles, this feature is extremely beneficial in allowing you to return to the exact coil height necessary every run. All portable systems come with our new, improved coil height handle which easily and quickly rolls your coil up or down into designated position.
