Rated By Mark C.

“Before purchasing Uniflow equipment, we started out using cold press, an incredibly labor-intensive process. As demand increased, we moved over to using a roll coater with a 5-gallon pail unloader. Over time, demand continued to increase, and it occurred to us that the labor involved in changing a 5-gallon pail was not much different than changing a 55-gallon drum, so we purchased a Uniflow hot melt drum unloader. I was, at first, reluctant to make the capital investment in a larger hot melt unloader, but the Uniflow system has met or exceeded my expectations in every way possible. There has been a significant improvement in productivity from using a 55-gallon drum unloader. The operator interface is simple and clear. The Uniflow team did a fantastic job of training our employees. We were very pleased with the install. The technician, the sales team, and everyone at Uniflow has been very helpful and patient.”
