Hot-melt adhesive system features automatic elevator

The Thermadose system encompasses bench mounted tank-style controllers designed to handle pellet, brick and flake hot-melt adhesives in 12, 14 and 34 lb capacities as well as heavier duty 5 gallon and 55 gallon drums. These include a smooth easy-clean heating platen or an optional spiral-grid that increases the surface area and improves heating efficiency and control for high-flow and hard to melt materials. The design features an automatic elevator which raises the drum during operation, eliminating safety handling issues and providing easy drum change without residue blow-out. All models are also available in versions to apply non-adhesive substances requiring sterile conditions. Crossover configurations for constant product flow are offered either as 55/5 gallon or 55/55 gallon configurations with simple to learn controls. When coupled to a range of heavy-duty heated accessories, the tank controller becomes part of a system that can be manually configured, for example, with a hand-gun or interfaced to a robot for fully automatic operation. Each hot-melt tank controller consists of a heated melt tank with an integral heat grid. Tanks are coated with an approved food contact material. Ergonomic and lightweight balanced dispensing guns have an integrated hanger for suspension hook up and incorporate hot-melt dispensing nozzles for fitting to applicator valves, manifolds and flow heads for swirl assemblies and pattern nozzles. Event timers are available in a 2-Event and 4-Event non-speed compensated models with independently selectable channels. Electric and air operated applicator valve heads are designed for mounted installation and feature a fast snap function solenoid valve with precise needle-and-seat action which produces a clean cut-off to preventing drips, e.g. when using edge dispensing manifold applicators - commonly used in corrugated or folded carton applications to dispense hot-melt in either horizontal or vertical modes. Accessories are available for angled dispensing. Thermadose hot-melt pail pump systems are available in 5 gallon and 55 gallon models. Connection is via hoses which incorporate a PTFE core, a reinforced stainless steel braid and high temperature insulation, with a durable polyester braid cover for abrasion resistance. These heated hoses are both electrically and mechanically attached to hot melt controllers via easy access front connector.
