4,500-gallon liquid storage tank built for agricultural chemical and fertilizer storage. Manufactured by Chemtainer from virgin linear polyethylene (HDPE) rated to handle liquids up to 12.5 pounds per gallon. Translucent white walls allow visual level monitoring without opening the tank and reflect sunlight to keep contents cooler.
The 4500 Gallon Plastic Vertical Liquid Storage Tank is designed for commercial operations, agricultural producers, and industrial facilities with serious storage demands. With 4,500 gallons of storage capacity, this tank serves as the backbone of serious agricultural chemical and fertilizer storage operations. It handles the volume demands of commercial and agricultural applications where running out of supply is not an option.
Constructed from virgin linear polyethylene (HDPE) using a single-piece rotational molding process that eliminates seams, weld lines, and potential leak points. Rated to 1.5 specific gravity, this tank handles liquids up to 12.5 pounds per gallon — covering the full range of agricultural chemicals, liquid fertilizers, and most industrial solutions. The wall thickness is engineered specifically for this density range. 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 156 inches tall with a 95-inch diameter, requiring 49.2 square feet of level ground. Empty weight is 1150 pounds. At full capacity with a 1.5 SG liquid, expect approximately 57,445 pounds on the foundation. Requires an engineered reinforced concrete foundation designed by a structural professional for the full loaded weight. Install on a level, compacted surface. Ensure adequate clearance above for lid access and around the perimeter for plumbing connections and visual inspection.
Comes equipped with a 2" 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 16" lid opening provides ample access for interior inspection, cleaning, and installation of float switches, level sensors, or submersible pumps. Install schedule 80 PVC or stainless steel piping on all 2" NPT connections. Full-port ball valves, expansion loops for thermal movement, and proper pipe support are essential at this scale.
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.
