100-gallon natural white cone bottom tank built for full-drain mixing and batch processing. Manufactured by Chem-Tainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 15.8 pounds per gallon. FDA approved for contact with potable water, ensuring safe storage for drinking water and food-grade liquids.
The 100 Gallon Chem-Tainer Cone Bottom Tank with Poly Stand is designed for chemical processors, water treatment plants, and agricultural operations requiring complete tank drainage. At 100 gallons, this cone bottom tank is sized for batch processing, chemical mixing, and applications where complete drainage between cycles is non-negotiable. The cone geometry eliminates the dead volume that flat-bottom tanks leave behind.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. The 1.9 specific gravity rating means this tank is built with significantly heavier wall sections than a standard water tank — necessary to safely contain liquids weighing up to 15.8 pounds per gallon. That extra wall thickness is not optional when you are storing aggressive industrial chemicals. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler. UV stabilizers are compounded directly into the resin — not a surface coating — for outdoor service life that lasts the full warranty period and beyond.
This tank measures 48 inches tall with a 31-inch diameter, requiring 5.2 square feet of level ground. Empty weight is 80 pounds. At full capacity with a 1.9 SG liquid, expect approximately 1,665 pounds on the foundation. Set on a flat, level pad of compacted gravel or a concrete slab at least 4 inches thick. Must be installed on the manufacturer-supplied or compatible stand rated for the full loaded weight. Never rest a cone bottom tank directly on its apex.
Comes equipped with a 1.5" NPT outlet fitting installed at the factory. No inlet fitting is included — drill and install a bulkhead fitting at your preferred height for your specific plumbing layout. The 8" Threaded Vented Lid lid accommodates fill lines, vent connections, and basic interior access for inspection. Standard garden hose adapter or direct NPT connection works well for tanks this size.
Chem-Tainer Industries has manufactured chemical-resistant polyethylene tanks in the USA since 1957. Their tanks are specifically engineered for chemical storage applications with wall thicknesses and resin formulations matched to the demands of aggressive chemicals. Backed by a 3-year manufacturer warranty from Chem-Tainer against defects in materials and workmanship under normal use conditions. FDA approved for contact with potable water and food-grade liquids. Every tank is inspected before it leaves the production floor — and we inspect it again before it ships from our facility.
