Localized Bulk Chemical Delivery
Self Contained, Low Cost, Ideal Wet Processing Solution

DrumChem
(55-gallon drum, self-contained)

Chemical Distribution Equipment: A self-contained bulk delivery system featuring modular, drum chemical delivery and recapture with on-demand controls. Multiple DrumChem systems can operate from a single remote kiosk or individually as a standalone system utilizing a dedicated controller. An integral 5-gallon reserve/day tank provides continuous chemical delivery during drum changes.

 

MEI‘s DrumChem Bulk chemical delivery systems are pumped or pressurized chemical delivery systems. Standard systems are designed for front and side access to components. They are configured for either one or two 55-gallon drums for acid, base, or solvent systems with internal drum hook-up. The units are modular with right or left internal component profile designs for easy maintenance access.
