55 Gallon Bulk Hot Melt Drum Unloader Systems

Uniflow Hot Melt Drum Unloaders are used in a wide array of industries and with a large selection of hot melt adhesives, but one thing is consistent. No other drum unloader can match the performance of a Uniflow. Why? Because Uniflow platens are machined from a solid piece of aircraft-grade aluminum, and then enables us to produce 6,000 square inches of heat transfer surface. That’s double the surface area of other platens, and it is why our melt rates and production rates eclipse the competition. When customers around the world want to improve their production rate without increasing their cost, they turn to Uniflow. And when they want to pump highly viscous hot melt materials, they can count on Uniflow.
