15 Gallon 60 Degree Cone Bottom Inductor Tank: Complete Buyer's Guide
Fifteen gallons, a 60-degree cone, and a 2-inch tip — the most aggressive drainer in the lineup, shrunk to a benchtop. That near-funnel slope means even thick, fast-settling concentrate slides straight to the outlet, making this the precision spot-mixer for the chemist who hates leaving anything behind.
Specifications at a Glance
Every figure below is pulled straight from the live product record for this exact tank — the same data on the product page, so what you read here and what you buy never disagree.
Standards & Materials
- ASTM D1998 — Standard Specification for Polyethylene Upright Storage Tanks. Governs wall-thickness and hydrostatic design for vertical rotomolded poly tanks of this class.
- FDA 21 CFR 177.1520 — Olefin polymers. The food-contact regulation the FDA-grade resin in this tank is compounded to meet.
- Specific gravity rating 1.5 — the tank is engineered for liquids up to 1.5× the density of water (water is about 8.34 lb/gal). Confirm your fluid’s SG before storage.
Product Overview
The 60-degree cone is what makes this little tank special. Where a 40- or 45-degree inductor compromises between drainage and height, the 15 Gallon 60 Degree Cone Bottom Inductor Tank goes nearly all-in on evacuation — a 60-degree slope is almost a funnel, steep enough to clear the heaviest, stickiest slurries to the tip with nothing clinging to the walls. For applications where carryover between batches is unacceptable, that angle is the whole reason to buy it.
This is the smallest inductor in the family: 19 inches in diameter, 23 inches tall, and just 13 pounds empty — light enough to pick up in one hand and move between work cells. It is purpose-built for small, precise batches: dissolving a measured additive, charging a metering eductor, or pre-mixing a potent concentrate before it joins a larger run. Filled to 15 gallons at the 1.5 specific-gravity rating it weighs only about 201 pounds, the lightest full charge in the range, but the cone-bottom rule still applies — that weight rides on a stand.
For such a compact tank the fittings are deliberately stout. A 2-inch NPT outlet at the tip will dump a viscous 15-gallon batch in seconds, and an 8-inch lid is sized for charging measured chemical and inspecting the cone rather than for bulk access. Translucent white walls let the operator watch a small, precise blend develop, and the seamless Norwesco mold means no weld seam to fail under repeated aggressive cycling.
Small as it is, this is chemical-process equipment. It blends and meters concentrates within its density rating — not drinking water — and is backed by Norwesco's 3-year manufacturing warranty.

Installation and Setup Guide
Even the smallest cone-bottom tank obeys the cone-bottom rules: support the body in a stand and keep all weight off the tip.
Stand and Support
Set the tank in a cone-bottom stand rated for the full charge — only about 201 pounds at 1.5 specific gravity, but the tip still cannot bear it. A 60-degree cone tapers to a sharp, narrow apex around the 2-inch outlet; rest the tank on that point and you concentrate the load on the most fragile geometry on the whole vessel. Level the compact stand on a hard bench or floor and confirm all legs touch so the steep cone drains true.
Plumbing the 2-Inch Outlet
A 2-inch outlet on a 15-gallon tank is intentionally oversized — paired with the 60-degree cone it lets even a thick, fully charged slurry clear in one quick drain. Fit a full-port 2-inch valve at the tip and keep the line to the eductor or pump short. Use chemical-rated flexible hose for the first connection; the small poly cone still flexes through fill-and-drain cycles, and rigid pipe would crack the boss.
Ventilation
Charge concentrate through the 8-inch lid in a ventilated work cell and reseat the lid before agitating. Even a small batch of potent concentrate produces vapor, so fit a vent matched to the chemistry rather than a bare screen, and keep eyewash within arm's reach — precision work with strong concentrate is exactly where a splash happens.
Maintenance and Long-Term Care
A precision spot-mixer earns its keep by leaving nothing behind, so its maintenance centers on keeping that 60-degree cone and 2-inch valve spotless between batches.
Between-Batch Inspection
- Cone clearance: A 60-degree cone should self-clear almost perfectly. Any clinging film signals either a chemistry far stickier than expected or a fouled tip — in a precision application, even a trace of carryover matters.
- 2-inch tip valve: Cycle the full-port valve and check the seat. The oversized outlet on a small tank passes concentrated, sometimes abrasive slurry, so inspect it often.
- Wall scan: Hold the small tank to the light and look for crazing or swelling — concentrated chemistry in a small volume can be deceptively aggressive.
- Stand and tip: Confirm the stand still supports the body fully and the sharp cone tip is not contacting anything that loads it.
Decontamination Between Chemistries
For a precision mixer, decontamination is non-negotiable: the entire value of a steep cone is zero carryover, and a film of the previous concentrate ruins that. Flush the body, cone, and 2-inch outlet to the chemical maker's procedure before each new formulation. This equipment is never sanitized and returned to potable use.
Long-Term Care
Out of direct sun the poly ages slowly. On a frequently cycled precision tank the 2-inch valve and the lid gasket are the consumables — keep spares so a worn part never compromises a measured batch.
Alternatives and Comparisons
The 15 Gallon 60 Degree Cone Bottom Inductor Tank is the smallest, steepest member of the cone family, and the comparison comes down to one trade: drainage versus height.
60 degrees vs. shallower cones: A 60-degree cone is the most aggressive drainer made — choose it when even a trace of carryover is unacceptable or when your chemistry is thick and fast-settling. The cost is height relative to diameter; a near-funnel cone stands tall. If your product flows freely, a 40- or 45-degree cone gives most of the drainage at a lower profile.
Capacity: At 15 gallons this is a precision spot-mixer, not a production blender. When batch volume grows past what a small charge supports, step up to a 35-, 60-, or 80-gallon cone; stay here when accuracy, zero carryover, and a one-hand-portable footprint are what the job demands.

Frequently Asked Questions
How long will the 15 Gallon 60 Degree Cone Bottom Inductor Tank last?
With compatible chemistries on a proper stand and out of direct sun, this small shell readily reaches 15-plus years. Because it handles concentrated product in a small volume, the aggressiveness of the chemistry — not age — is the main risk: strong concentrate can craze poly, and abrasive slurry wears the 2-inch valve. Decontaminate after every batch and inspect the cone, and the tank body will outlast many rounds of valve seats and gaskets.
What chemicals can I store in this tank?
This is chemical-process equipment rated to 1.5 specific gravity, built to dissolve, blend, and meter concentrated agricultural and industrial chemistries within that density — additives, surfactants, fertilizer concentrates, and water-based cleaning solutions. It is not for drinking water and never for fuels, solvents, or flammables. Concentrated product is harder on poly than dilute, so always confirm compatibility against a polyethylene chart before charging.
Does this tank come with a warranty?
Yes — Norwesco's 3-year warranty covers material and workmanship defects when the tank is used within its ratings, including molding flaws around the 2-inch outlet boss. It excludes chemical attack from an incompatible or over-concentrated product, a cone cracked by tip-loading, and normal valve and gasket wear. Keep your invoice and a photo of the tank seated in its stand.
Can I install this tank underground?
No. A 60-degree cone is the thinnest, most steeply tapered geometry in the lineup — the exact opposite of what resists soil pressure. Burial would crush the cone instantly and void the warranty. This is above-ground precision equipment. For underground storage, use a ribbed, reinforced cistern built to take backfill loads.
Buying Considerations
Before ordering the 15 Gallon 60 Degree Cone Bottom Inductor Tank, confirm three things. First, the stand — even at a light 201-pound full charge the tank cannot rest on its sharp 60-degree tip, so you need a matched cone-bottom stand. Second, the cone angle — verify 60 degrees suits the job; it is the most aggressive drainer for zero carryover but stands tall for its diameter. Third, compatibility — concentrated product is hard on poly, so check every chemistry against a polyethylene chart and stay within the 1.5 specific-gravity rating; this is a chemical mixer, never a water tank. At 13 pounds empty it ships UPS or FedEx ground in 5 to 7 business days.
