80 Gallon 45 Degree Cone Bottom Inductor Tank: Complete Buyer's Guide
At 80 gallons this is the largest of the 45-degree induction cones — a half-ton of working chemistry on a single steep cone that drains to a 2-inch tip. The wide 16-inch lid turns it into a true mixing station rather than a charging port, while the seamless Norwesco shell keeps the seam count where it belongs: zero.
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
When a mixing line needs both volume and a clean drain, the 80 Gallon 45 Degree Cone Bottom Inductor Tank is where those two demands meet. The 45-degree cone is steep enough to evacuate sticky concentrates and fast-settling solids completely, and at 80 gallons it carries enough blend to feed a sustained eductor run or charge a sizable downstream batch without constant recharging.
This tank is broader and more substantial than the small benchtop inductors — 32 inches in diameter and 37 inches tall — built to be a fixed station rather than something you reposition between jobs. It is light to handle empty at 34 pounds, but a full 80-gallon charge at the 1.5 specific-gravity rating loads roughly 1,035 pounds onto the stand. That is the headline number for installation: a half-ton, transferred entirely through the cone, demands a stand engineered for it.
The fittings reflect the larger duty. A 2-inch NPT outlet at the tip moves a thick blend or a partly dissolved slurry without choking, and the 16-inch lid is wide enough to mount an agitator, charge bulk chemical, and reach in to scrub the cone between formulations. Translucent white walls keep the blend visible from outside, and Norwesco's seamless rotational mold means there is no weld line anywhere for an aggressive concentrate to exploit.
This is dedicated chemical-handling equipment. It inducts, blends, and meters agricultural and industrial solutions within its density rating — it is not a drinking-water tank — and the shell carries Norwesco's manufacturer warranty against defects.

Installation and Setup Guide
An 80-gallon inductor is a fixed installation, and the entire job hinges on supporting roughly a half-ton through a single cone.
Stand and Support
The stand must be rated for the full loaded weight — about 1,035 pounds at 1.5 specific gravity. This is the heaviest of the 45-degree inductors, so a stand that handled a 35- or 60-gallon unit is not automatically adequate; check the rating against the number. Anchor the stand to a level concrete floor, confirm all legs share the load, and let the broad cone hang square so it drains evenly to the tip. The apex carries the 2-inch outlet and is never a support point — bearing the half-ton load there will split the cone.
Plumbing the 2-Inch Outlet
Plumb the 2-inch NPT tip outlet with a full-port valve and the shortest practical run to your pump or eductor. With 80 gallons standing above a steep cone, the head pressure clears a thick blend fast — do not throttle it with reducers or long horizontal pipe where slurry can settle. Take the first connection in chemical-rated flex hose to absorb thermal movement from the taller, heavier column.
Ventilation and Agitation
The 16-inch lid makes this a genuine mixing station, so plan for agitation: mount any mixer so its shaft is centered and the cone is not loaded sideways. Charge and mix in a ventilated area, keep the lid seated during agitation to contain the larger splash, and fit a vent matched to the chemistry rather than a plain screen. Position eyewash within reach of the working face.
Maintenance and Long-Term Care
The bigger the inductor, the more it pays to keep the cone clean and the working parts fresh — a half-ton batch is an expensive thing to contaminate or spill.
Between-Batch Inspection
- Cone evacuation: Verify the 45-degree cone drains completely to the tip. On a wide cone, product left in one quadrant usually means the stand is no longer level or a leg has settled.
- 2-inch valve: Cycle the full-port tip valve and check the seat. The wide outlet passes more abrasive slurry per batch than a small port, so wear accumulates faster.
- Agitator interface: Inspect the mixer mount and shaft seal at the lid — a leaking seal drips concentrate down the outside of the tank and onto the stand.
- Wall and stand: Backlight the translucent wall for crazing, and confirm the stand still carries the full 1,035 pounds square and uncorroded.
Decontamination Between Chemistries
Flush and decontaminate the body, cone, agitator, and 2-inch outlet per the chemical manufacturer's procedure before switching products. An 80-gallon vessel with an agitator holds residual concentrate in more places — the cone, the shaft, the lid underside — so a thorough decon protects the larger downstream batches this tank exists to feed. It is never returned to potable service.
Long-Term Care
Indoors and shaded, the shell ages slowly; on a high-volume mixer the wear lands on the tip valve, the agitator seal, and the lid gasket. Keep those spares stocked so a worn consumable is a quick swap rather than a halted line.
Alternatives and Comparisons
The 80 Gallon 45 Degree Cone Bottom Inductor Tank is the high-capacity choice in the 45-degree cone family, and the comparison is about throughput versus footprint.
Why size up to 80 gallons: If your line is recharging a smaller inductor too often, 80 gallons buys longer runs between charges and enough volume to feed a real eductor circuit. The cost is footprint and weight — this is a fixed station carrying a half-ton when full, not a movable bench tank.
Cone angle: The 45-degree slope is well suited to sticky or fast-settling chemistry, draining cleanly where a shallower 40-degree cone might leave a film. If you need still more aggressive evacuation of dense solids and can accept a taller tank, a 60-degree cone clears faster; for most blends, 45 degrees is the practical optimum at this capacity.

Frequently Asked Questions
How long will the 80 Gallon 45 Degree Cone Bottom Inductor Tank last?
With compatible chemistries, a stand rated for the full half-ton charge, and shelter from direct sun, this shell readily exceeds 15 years. On a high-volume inductor the duty cycle, not the plastic, sets the pace: the 2-inch tip valve and the agitator seal wear from abrasive slurry, and an over-aggressive concentrate can craze the wall. Thorough decontamination and a post-batch cone check keep the tank itself at the long end of its life.
What chemicals can I store in this tank?
This is chemical-mixing equipment rated to 1.5 specific gravity, built to induct and blend agricultural and industrial concentrates within that density — liquid fertilizers, surfactants, wettable powders, and water-based cleaning chemistries. It is not for drinking water and never for fuels, solvents, or flammables. Verify every new product against a polyethylene compatibility chart, because certain oxidizers and hydrocarbons attack poly even at moderate strength.
Does this tank come with a warranty?
Yes — Norwesco backs the shell with a manufacturer warranty against material and workmanship defects when used within its ratings, covering molding flaws such as pinholes and voids. It does not cover chemical attack from an incompatible product, a cone damaged by tip-loading, or wear to valves, seals, and gaskets, which are normal-service items on a mixing tank. Keep your invoice and a photo of the tank seated correctly in its stand.
Can I install this tank underground?
No. The steep, thin-walled cone that drains so well is the worst possible shape for resisting soil pressure — backfill would crush it, and burial voids the warranty. This is an above-ground mixing station. For below-grade storage, use a purpose-built underground cistern with ribbed, reinforced walls designed for burial loads.
Buying Considerations
Three checks before ordering the 80 Gallon 45 Degree Cone Bottom Inductor Tank. First, the stand — rated for the roughly 1,035-pound full charge, which is heavier than smaller inductors require; the cone transfers all of it and cannot stand alone. Second, the agitation plan — the 16-inch lid invites a mixer, so confirm you can mount it centered and ventilate the larger charge. Third, compatibility — verify your concentrates are poly-safe and within the 1.5 specific-gravity limit, since this is chemical-process gear and never a water tank. At 34 pounds empty it ships UPS or FedEx ground in 5 to 7 business days.
