Cone Bottom Tanks — 100% Drainage. Zero Residue.
Choose cone bottoms when complete drain-out is critical—like sodium hypochlorite or sludge-heavy wastewater. A James Riggins–spec’d system dials in cone angle, resin, stand, and fittings so you avoid sludge, cleanouts, and fines—and get a 20+ year life.
The James Factor: Cone Specs You Don’t Have to Second-Guess
James pairs the right cone angle, resin, stand, and drain outlet so you get 100% drainage, clean audits, and maximum uptime.

- Range: ~12–20,000 gal (varies by model)
Design Note: Full Drainage Depends on Angle, Outlet, and Stand
Cone bottom tanks require a correctly engineered cone angle, drain outlet (e.g., IMFO®), and factory stand. Get one wrong and you’ll see residue buildup, stress cracking, or even a voided warranty.
James’ approach: specify the right angle (15°/30°/45°), resin (HDPE/XLPE/PP), outlet (IMFO® when purity and zero residue matter), and the approved stand—then integrate containment and controls so operators get clean batches and long service life.

Cone Bottom Tank FAQ
When should I use a cone bottom vs. a flat bottom tank?
Use a cone bottom when 100% drainage is critical—like sodium hypochlorite, biodiesel, or any sludge-bearing liquid. Full drain prevents residue, costly cleanouts, and batch contamination.
What is an IMFO® tank?
IMFO® (Integrally Molded Flanged Outlet) is a Poly Processing design where the outlet flange is molded into the tank’s bottom for full drainage with no internal fittings that can leak or fail.
What’s the most important part of a cone bottom spec?
The stand. It must be factory-engineered for the tank diameter, cone angle, specific gravity, and seismic zone. The wrong stand can void the warranty and jeopardize safety.
Which resin should I choose—HDPE, XLPE, or Polypropylene?
PP is the high-temperature option (to ~200°F water / 180°F chemicals) and resists pH 0–14; XLPE improves stress-crack resistance for some oxidizers; HDPE covers standard duty. James matches resin to chemistry, temp, and SG.
Can Liberty integrate pumps, skids, and monitoring?
Yes. Liberty provides single-point accountability—tanks, feed skids, transfer pumps, and SCADA-ready controls—all spec’d by James.
