20 Ton Hydraulic Drum Unloader – Model 230

Uniflow Model 230 Hot Melt Drum Unloader

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.

Consistently outperforms the competition.

How do we beat the competition? Uniflow platens are machined from a solid piece of aircraft-grade aluminum, and that enables us to produce 4,663 square inches of heat transfer surface. That’s double the surface area of other platens and is why our melt rates and production rates eclipse the competition.

Improves production without increasing costs.

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.

Here’s What Customers Are Saying about the Uniflow Model 230:

“IMMCO made a big improvement on our production speed. The Uniflow Model 230HO gave us double the pump rate of what we were getting from our other hot melt drum unloaders. They make a good piece of equipment, and we would readily buy another one.”
