The co.’s PUR hot-melt units are designed for the delivery of PUR (polyurethane reactive) hot melt. They feature a locking-lid assembly and a nitrogen or dry-air kit. Each time the lid is opened and closed, there is a burst from the nitrogen kit that injects a blanket of nitrogen or dry air onto the top of the molten adhesive to keep it from curing inside the melt tank. The melt units are available in 16- and 30-L capacities, with multiple gear pumps and up to 6 hose/gun outputs. They can be used with a range of standard hoses and are typically used with zero-cavity or hot-melt valves and short engagement nozzles.
