35 Gallon 45 Degree Cone Bottom Inductor Tank: Complete Buyer's Guide
The 45-degree cone on this 35-gallon inductor is steep by design — it sheds clingy powders and fast-settling slurries that a shallower cone would leave behind. A factory 2-inch NPT outlet at the tip and an 8-inch charging lid make it a tidy, fully draining mix vessel for tight benches.
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
Cone angle is the spec that defines this tank. At 45 degrees, the cone on the 35 Gallon 45 Degree Cone Bottom Inductor Tank is appreciably steeper than the 40-degree designs — and that extra slope is the whole point. Sticky concentrates, wettable powders that want to cling, and solids that drop out of suspension fast all evacuate more completely down a 45-degree wall, leaving the tank genuinely empty rather than coated.
This is the compact end of the inductor range: 23 inches across and 29 inches tall, light enough at 17 pounds to lift onto a stand single-handed. It is built for the operator doing precise, repeatable small batches — spot-mixing a concentrate, charging an eductor, or pre-blending an additive before it joins a larger run. A full 35-gallon charge at the 1.5 specific-gravity rating comes to about 455 pounds, all of which the stand carries.
The fittings suit deliberate work. A 2-inch NPT outlet is molded and leak-tested at the cone tip, sized to dump a viscous blend quickly or feed a transfer pump without throttling. The 8-inch lid is a charging and inspection port rather than a walk-in opening — appropriate for a tank this size, where you are adding measured chemical, not climbing inside. Translucent white walls let the operator track the blend by eye, and the seamless one-piece Norwesco mold leaves no weld line for aggressive chemistry to find.
As with every cone-bottom inductor, this is chemical-process equipment. It blends and meters agricultural and industrial solutions within its density rating — not drinking water — and is backed by Norwesco's 3-year manufacturing warranty.

Installation and Setup Guide
A small inductor is quick to set up, but the rules are the same as any cone-bottom tank: the stand carries the weight, and the tip is never a foot.
Stand and Support
Seat the tank in a cone-bottom stand rated for the full charge — about 455 pounds at 1.5 specific gravity. Even on a compact 35-gallon unit, resting the cone tip on the bench instead of supporting the body in a stand will eventually split the apex around the 2-inch outlet. Level the stand on a hard floor and check that all legs bear evenly so the steep cone drains symmetrically to the tip.
Plumbing the 2-Inch Outlet
The factory 2-inch NPT tip outlet is generous for a 35-gallon tank, which is exactly what you want with a steep cone — it lets a thick blend or a slurry of partly dissolved powder clear in one fast drain. Fit a full-port 2-inch valve at the tip and keep the run to the pump or eductor short and straight. Use chemical-rated flexible hose for the first connection so the poly cone can flex through fill-and-drain cycles without cracking the threaded boss.
Ventilation
Charge chemical through the 8-inch lid in a ventilated area and reseat the lid before agitating to contain splash. Match the vent to the product — many concentrates require a pressure/vacuum relief vent rated for the chemistry rather than a bare screen — and keep eyewash within reach of the charging station.
Maintenance and Long-Term Care
A small inductor cycles fast and often, so its upkeep is brisk: clear the cone, mind the 2-inch valve, and never carry residue from one chemistry into the next.
Between-Batch Inspection
- Cone clearance: A 45-degree cone should drain bone-dry. If product hangs on the wall, the chemistry is clingier than expected or the tip valve is restricting flow — investigate before the next charge.
- 2-inch tip valve: Cycle the full-port valve and feel for grit; the wide outlet passes more abrasive slurry than a small port, so inspect the seat regularly.
- Wall scan: Backlight the translucent wall and look for crazing or swelling that signals an over-aggressive concentrate.
- Stand contact: Verify the compact stand has not crept or lost a leg's contact; even small tanks tip product to one side when the cone hangs off-axis.
Decontamination Between Chemistries
Because this tank is built for spot-mixing and frequent product changes, decontamination is the routine, not the exception. Flush the body, cone, and 2-inch outlet to the chemical maker's procedure before each new formulation; a steep cone drains liquid well but can still hold a film that contaminates the next blend. This is process equipment and is never sanitized back to potable use.
Long-Term Care
Kept indoors and out of direct sun, the shell ages slowly. On a high-cycle small inductor the consumables — the 2-inch tip valve and the lid gasket — wear first; keep replacements on hand so a worn seat never holds up a batch.
Alternatives and Comparisons
The 35 Gallon 45 Degree Cone Bottom Inductor Tank is the small-batch member of the cone-bottom family, and the comparison is really about cone angle and capacity.
45 degrees vs. shallower cones: The steep 45-degree slope here is the right call for sticky or fast-settling chemistry — it self-clears where a 40-degree cone might leave a film. The trade is height: a 45-degree cone stands taller for the same diameter, so a steeper cone always costs a little overhead. If your product flows freely and stays in suspension, a shallower cone would do and sit lower.
Capacity: At 35 gallons this is for measured, repeatable small batches rather than bulk blending. Step up to a 60- or 80-gallon cone when batch volume grows; stay here when precision and a tidy bench footprint matter more than throughput.

Frequently Asked Questions
How long will the 35 Gallon 45 Degree Cone Bottom Inductor Tank last?
With compatible chemistries on a proper stand and out of direct sun, this shell readily passes 15 years. On a frequently cycled small inductor, the wear shows up at the 2-inch tip valve and the lid gasket long before the poly itself gives out — abrasive slurry is hard on a valve seat. Decontaminate between products and inspect the cone after each batch, and the tank body will outlast many rounds of consumables.
What chemicals can I store in this tank?
This is chemical-process equipment rated to 1.5 specific gravity, built to mix and meter agricultural and industrial concentrates within that density — fertilizers, surfactants, wettable powders, and water-based cleaning chemistries. It is not for drinking water, and never for fuels, solvents, or flammables. Confirm any new product against a polyethylene compatibility chart first, since some oxidizers and hydrocarbons attack poly.
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 like pinholes around the 2-inch outlet boss. It does not cover chemical attack from an incompatible product, a cone cracked by tip-loading, or 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 45-degree cone is thin and steeply tapered for drainage, not for resisting the inward crush of soil — burial would collapse it and void the warranty. This is above-ground process equipment. For underground storage, choose a ribbed, reinforced cistern engineered to take backfill and groundwater loads.
Buying Considerations
Before ordering the 35 Gallon 45 Degree Cone Bottom Inductor Tank, line up three things. First, the stand — rated for the roughly 455-pound full charge, because the cone cannot stand on its own. Second, the cone angle — confirm 45 degrees suits your chemistry; it is the steeper choice that self-clears clingy powders but stands a little taller for the same diameter. Third, compatibility — verify your concentrates are poly-safe and within the 1.5 specific-gravity rating, since this is a chemical mixer and not a potable-water tank. At 17 pounds empty it ships UPS or FedEx ground in 5 to 7 business days, no liftgate needed.
