Retrofit system for melters

The system replaces manual melter monitoring and refilling with an automatic, controlled process, decreasing exposure to hot surfaces, molten adhesive and repetitive lifting of adhesive. The system is closed to ambient air, preventing adhesive contamination by dirt, dust or other debris. Includes a vibrating vacuum wand to help prevent adhesive from sticking in the tote container; an external control box with membrane panel, a fill/fault indicator, and a disposable filter, for easy maintenance. Pre-assembled and pre-calibrated components.
