Norwesco 200 Gallon Horizontal Elliptical Cradle Tank in White

The low one of three, and why the height decides it

The sheet names two other records and they separate almost entirely on height. The N-41305 holds the same 200 gallons at the same 82 lb but in a 61 x 24 x 48 shell: narrower by a long way and eighteen inches taller. The N-40327 holds 300 gallons in a 70 x 48 x 36 shell at 114 lb. This record is the flattest of the three at 30 inches tall, and that single number is why people buy it. Thirty inches is bench height, truck-bed height, under-a-shelf height, the height at which a lid is reachable without standing on anything and a tank does not block a sight line across a yard. If your constraint is a ceiling, a shelf or a structure to slide under, this is the record in the family; if your constraint is floor width, the N-41305 does the same 200 gallons in a 24 inch wide body and asks for headroom instead. The N-40327 is the one to look at if you would rather make one trip than two, and it costs you six more inches of height and eight more inches of width to get there. The other reason to choose this record over its siblings is on the fittings line: it is the only one of the three whose sheet publishes an inlet as well as an outlet, and both are described identically. A published inlet is worth real money on an installation where the fill is plumbed rather than poured, because it means the fill point is designed in rather than improvised through the lid. Size the volume against the work with the tank sizing calculator and read the usable-volume section of the tank sizing guide before settling on 200 gallons, because on an elliptical shell the top few inches hold much less per inch than the middle does. The honest limitation is support. A 66 inch elliptical body is not a self-supporting shape: it has to lie in a cradle or a bed shaped to it along the full length, and this record publishes no cradle, no frame and no support specification.

Three records, three shapes, two capacities

The two 200 gallon records weigh the same 82 lb and hold the same volume in completely different envelopes, which is the clearest illustration you will find of why capacity is the last column to read. One is 40 inches wide and 30 tall; the other is 24 inches wide and 48 tall. Neither is better. The one that fits the space you actually have is better. When you step up to the N-40327 the pattern continues: 300 gallons arrives as more width and a little more height rather than more length, so the extra volume costs you floor rather than run. Take a tape to the site before you take a view on gallons, and write down the three numbers that cannot change: the clear height above the bed, the clear width between whatever the tank has to sit between, and the length of bed you can actually build.

The only vented lid in this family

Air is usually the thing a tank record leaves to you, and this one does not, which is worth starting with. The lid field reads 8 inch threaded vented lid. That word is doing real work: it says the opening is intended to let air move as well as let liquid in. Keep the vent path clear, check it every time the lid comes off and goes back on, and do not seal over it because something splashed. Drawing 200 gallons out through a 1-1/4 inch port against a blocked vent will pull a 66 inch elliptical shell out of shape, and the vented lid is the feature that stops that happening. Everything else on the fittings list assumes that path is open.

• Outlet: 1-1/4 inch PP female NPT bulkhead fitting, as the sheet describes it. That sets your valve size, your line size and the realistic drain rate for the whole tank.
• Inlet: 1-1/4 inch PP female NPT bulkhead fitting, described identically. Both ends take the same size, so a single line stock covers the installation.
• Fit a full-bore valve tight against the outlet bulkhead and a union immediately below it, so future pipework changes happen below the union and never load the shell.
• Carry the pipe weight on the bed or the wall. A horizontal tank sits low, which makes it easy to hang a heavy line off a bulkhead without ever noticing you have done it.
• Access: an 8 inch threaded vented lid, with the lid size field also reading 8 inches. Eight inches takes a light, a hose and a hand; it does not take an arm to the far end of a 66 inch body, so cleaning is a flushing job.
• Service limit 120 F / 48 C, density field 1.5, maximum contents 2502 lb, warranty field blank.

The install specific is the bed. Support the body continuously along all 66 inches with the contour of the ellipse followed, no point loads under the belly, and nothing bearing on the two ends. Set it empty, fill it once, and then look again: 1668 lb of water finds every part of a bed that was only nearly touching.

Bench height bulk

The product application field reads cradle storage tanks. In practice this is the size and shape that replaces a cluster of drums in a shop, a wash bay or a service building: a fixed 200 gallons at a height you can work over, plumbed in at both ends, drawn down by pump or by gravity depending on where the bed sits. It suits a day tank feeding a metering pump, a rinse or make-up supply beside a bench, a low-profile reserve under a mezzanine or a shelf, and any duty where the tank has to be part of the room rather than the largest thing in it. What it does not suit is anything that has to empty absolutely clean between products, because a flat-bellied elliptical shell holds a film across a large area where a cone bottom would not, and anything above the published 120 F / 48 C service line. If the liquid is heavier than water, check it against the 1.5 density figure and the 2502 lb maximum contents figure on this record before you order, and call us if either number is close.

Six plants, six states, 82 pounds

Six plants are named on this record: Lancaster, Ohio; Griffin, Georgia; Tooele, Utah; Sheldon, Iowa; Hanford, California; and Fairfield, Texas. The ship-from list reads California, Georgia, Iowa, Ohio, Texas and Utah, which matches the plant list state for state; that one-to-one agreement is unusual enough on a Norwesco sheet to be worth noting, and it means the origin of your tank is genuinely predictable. Freight class and ship mode both read LTL, the NMFC field is 156600-03, and the shipping weight repeats the 82 lb empty figure. The freight cost estimator will price the lane to your ZIP, and the listed price is before freight. At 82 lb in a 66 inch body this travels as a light, awkward item rather than a heavy one, so the receiving risk is handling rather than equipment: take it off the truck by the body with two people rather than dragging it by the lid collar or a bulkhead. Check that the 8 inch vented lid turns freely before the tank leaves the dock, because a lid cross-threaded in transit is far easier to settle with the driver still standing there than a week later. Keep one spare gasket for the outlet fitting on the shelf; it is the part that fails on a holiday.
