Colder Products Company”s DrumQuik PRO is a closed chemical dispensing system designed to facilitate safe, easy, and economic extraction of chemicals from plastic drums, jerry cans, and IBCs. This chemical management system is comprised of two major components; a low-cost and recyclable drum insert assembly that combines a bung closure and a dip-tube. The drum insert assembly seals the container for transport from chemical packager to the end -user site. The second component is a rugged, reusable quick-disconnect coupler (dispense head) that is installed at the point-of-use. The coupler incorporates an automatic shutoff valve, which prevents chemical media from leaking out when it is disconnected from the drum insert during container change-outs. It also ensures that both sides are sealed from point-of-origin to point-of-use. The coupler also incorporates a vent port for controlled venting of the container.
