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 30 Gallon 57 Degree Cone Bottom Inductor Tank doubles the batch capacity of the 15-gallon model while keeping the same purpose: it is a mixing and chemical-induction vessel for blending, dissolving, and metering, not a storage tank. The 57-degree cone drives every batch toward the bottom outlet for complete discharge, so solids and slurry leave cleanly instead of settling on a flat floor.
It is molded as one seamless piece of virgin linear polyethylene rated to 1.5 specific gravity, capable of the heavier induction chemistries up to 12.5 pounds per gallon. Like all cone-bottom tanks, it has no flat base to stand on; it is built to be carried in a stand or leg set that bears the load through the rim and skirt, leaving the cone apex free for the outlet.
Standing 28 inches tall over a 24-inch span, it weighs 20 pounds empty and about 395 pounds with a full 1.5-SG mix — still compact enough for a cart or skid station. The 16-inch lid opens wide for charging dry product, mounting a mixer or eductor, and reaching in to clean the cone between runs.

Installation and Setup Guide
Like every inductor, this 30-gallon tank lives in a stand — its 57-degree cone has no flat bottom, so it is supported by its rim and skirt while the cone hangs free, and it must never bear on the apex. Fix the stand to a level, rigid bench, cart, or skid rated for the full batch, and make sure the framework leaves the bottom outlet clear so a valve and drain line can hang beneath it.
Site Preparation
Set it up as a process station with room to work above and below. Above, leave clearance to charge dry chemical through the 16-inch lid and to fit the mixer or eductor your batching requires; below, keep the cone outlet reachable for valving and drainage. At about 395 pounds full, the design driver is a stiff, level, vibration-resistant mount rather than a heavy foundation — mixing forces, not static weight, are what stress an inductor stand.
Placement and Connections
Plumb the cone outlet for full, trap-free discharge, since the entire value of the 57-degree geometry is that contents drain to one low point and out. Use piping compatible with the specific chemistry, keep the run short and downhill, and fit a valve at the outlet. Hand-tighten the poly threads a quarter turn past snug — the boss on a cone outlet is easy to crack with a wrench under the leverage a stand provides.
Venting
Charging and recirculating chemicals shifts air in and out of the tank, so vent it through the lid. An open screened vent serves typical batch work; for volatile or off-gassing chemistries, fit a pressure/vacuum relief vent matched to the chemical. With a faster eductor pulling 30 gallons through quickly, an unvented tank can pull a real vacuum, so never seal it shut during recirculation.
Maintenance and Long-Term Care
As a 30-gallon process vessel, this tank sees batches, chemical swaps, and routine cleaning, so its upkeep is about the cone, the outlet, and decontamination between runs — the maintenance mindset of mixing equipment, not of a tank that simply holds liquid for months.
Quarterly Inspection Checklist
- Cone drain check: After batches, confirm the 57-degree cone empties completely through the outlet; clinging residue points to a restriction or a chemistry that needs a more thorough flush.
- Stand and seating: Verify the stand is solid and the tank still rests on its rim and skirt, with no load on the cone tip.
- Connection check: Hand-snug the outlet valve and process fittings, which mixing vibration loosens over time.
- Vent verification: Make sure the lid vent or pressure/vacuum relief is open, clean, and rated for the current chemistry.
Cleaning
Treat cleaning as decontamination, not just rinsing: follow the chemical manufacturer's guidance whenever you switch between incompatible chemistries in this tank. The 57-degree cone helps by draining fully through the outlet, and the 16-inch lid gives direct access to scrub the cone walls and clear any film between runs. This is a chemical-mixing vessel and must not be used for potable or drinking water.
UV and Weather Protection
Where the station sits outdoors or under strong light, the resin's UV stabilizer protects the wall, but inspect the exposed face occasionally for chalking. Most 30-gallon induction setups are indoor cart or skid stations, where UV plays no part and the tank's longevity is dictated by the chemistries it mixes and how it is cleaned.
Alternatives and Comparisons
At 30 gallons, this inductor splits the difference between the small benchtop 15-gallon unit and the larger 60-gallon model, all sharing the 57-degree drain cone. For bigger batches, step up to the 60-gallon; for true bulk chemical storage rather than mixing, a vertical liquid tank is the right vessel. Choose by batch size first, then by whether you are inducting or storing.
Cone Bottom vs. Flat Bottom: Cone bottom tanks allow complete drainage without tilting or pumping. The trade-off is you need a stand, which adds height and cost. If your application doesn't require 100% drainage between batches, a flat-bottom tank is simpler and cheaper.

Frequently Asked Questions
How long will the 30 Gallon 57 Degree Cone Bottom Inductor Tank last?
This inductor's working life is governed by the chemicals it processes and the care it gets between batches more than by its age. Run within the 1.5 SG rating, cleaned to chemical guidance, and supported properly on its stand, the seamless wall lasts for years of service; incompatible or aggressive chemistries, not time, are what wear it out.
What chemicals can I store in this tank?
Rated to 1.5 specific gravity, it handles heavier induction chemistries up to 12.5 pounds per gallon, but every specific chemical must be checked against a polyethylene compatibility chart before use. No fuels, solvents, or flammables should ever go in. It is a chemical-mixing tank and is not intended for potable water.
Does this tank come with a warranty?
Yes — the manufacturer covers it against defects in materials and workmanship under normal use, meaning factory faults rather than damage from incompatible chemicals, exceeding 1.5 SG, resting the tank on its cone tip, or impact. Keep the purchase receipt accessible for any claim later on.
Can I install this tank underground?
No. A cone-bottom inductor has no flat base and is built to hang in a stand for mixing and discharge, not to resist burial loads. It is an above-ground process vessel only; for storage, choose a flat-bottom tank, and for below-grade needs an underground cistern.
Buying Considerations
Buy this for a mixing process, not for storage: confirm a level, rigid bench or skid rated for a full 30-gallon batch, ensure the stand carries the cone on its rim and skirt, and plan the bottom-outlet plumbing and venting around the chemistry you will run. If you only need to hold liquid, a flat-bottom tank is cheaper and self-supporting.
