Horizontal Tanks
Horizontal Tanks — Low Profile. Rock-Solid Stability.
Height is tight. Loads are heavy. We spec horizontal tanks that won’t slosh, crack, or loosen fittings — matched to your chemistry and duty cycle, so you get safe storage and clean transfers without downtime.

Why Horizontal — and Why Specs Matter
Choose horizontals for height-restricted rooms, mobile builds, skid/saddle mounting, nurse service, and any process needing a lower center of gravity. Get the geometry, resin, SG and restraint right — avoid stress cracks, spills, and compliance headaches.
- Low profile = safer handling on trailers, skids, and under mezzanines.
- Slosh control & support via engineered hoops/cradles (mandatory on many leg tanks ≥ ~730 gal).
- Compliance-fit resins (HDPE/XLPE; PP where heat/chemistry demands).
- Food/Water compatible options (FDA 177.1520 and NSF/ANSI 61 where required).
- UV-stabilized for long outdoor duty; opaque builds for outdoor oxidizers.
- We specify wall thickness, SG rating, tie-downs, hoops, and fittings to your load case & chemistry.

Horizontal Storage (Low Profile)
30–535 gal up to ~3,400 gal lines
Best for: Indoor installs with height limits, small skid day tanks.
Notes: Translucent walls w/ gallon marks; 1¼–2″ outlets; up to 1.9 SG.
Horizontal Leg Tank (with Hoops)
~730–3,400 gal
Best for: Mobile/nurse service; bulk transfer; trailer/truck mounting.
Notes: Hoop assemblies required; tie-downs & skid padding; 1.5 or 1.9 SG.
Elliptical Leg Tank
~3,000 gal class (often 1.5 SG)
Best for: Lower center-of-gravity on trucks/trailers; more stable transport.
Notes: Hoops required; choose SG for route roughness & contents.
PCO / Utility Horizontal
30–325 gal
Best for: Pest control, small service trucks, washdown, light chem/water.
Notes: Often 1.9 SG; compact footprints; 6–18″ lids; ¾–2″ outlets.
Style Selector — What to Choose When
| Style | Height limit? | Mobile? | Typical Range | Best For | Must-Have |
|---|---|---|---|---|---|
| Horizontal Storage (low profile) | ✅ | ➖ | 30–535 gal, up to ~3,400 | Indoors, mezzanine/low headroom, day tanks | Proper SG, right outlet, opaque/insulated for bleach outdoors |
| Horizontal Leg Tank | ➖ | ✅ | ~730–3,400 gal | Nurse/transport, field transfers | Hoops/bands/J-bolts, skid padding, valve guards |
| Elliptical Leg Tank | ✅ | ✅ | ~3,000 gal | Trailer stability, lower CG | Hoops/bands; route-appropriate SG |
| PCO / Utility | ✅ | ✅ | 30–325 gal | Service vehicles, pest control, washdown | 1.9 SG, compact footprint, correct outlet size |
What to Tell Us — So We Nail the Spec
| Parameter | What we need | Why it matters |
|---|---|---|
| Contents | CAS/trade name, concentration, pH, SG | Resin + SG rating + gasket/fitting materials |
| Use | Stationary vs mobile; trailer/truck dims; headroom | Hoops/bands count, tie-downs, geometry |
| Flow | Fill/empty method, pump rate, outlet size | Outlet, valve guards, slosh control |
| Codes | NSF/ANSI 61, food contact, wind/seismic, containment | Compliance assurance + restraint kit selection |
| Environment | Indoor/outdoor, sun exposure, freeze/dewpoint risk | UV block-out, insulation/heat trace packages |
| Accessories | Hoops, skids, ladders, level sensors, mixers, heat trace | Complete install package + submittals |
Specifically Engineered for Your Use Case
- SG rating: 1.35 / 1.5 / 1.9 — selected for density + slosh loads + transport.
- Hoops & restraints: Required on many leg tanks ≥ ~730 gal; we size hoop count and bolt kits; add saddle bands and skid padding.
- Tie-downs & wind/seismic: 150 mph wind & IBC/ASCE style restraint logic available — tell us your jurisdiction.
- Fittings & outlets: Heavy-duty bolted fittings standard on many ≥ ~550 gal lines; PP/PVDF/SS + EPDM/Viton per chemistry.
- UV & outdoor duty: UV-stabilized resin; opaque block-out or insulated packages for outdoor oxidizers.
- Level indication: Translucent walls + gallon marks; add sight tubes or sensors as needed.
- Access & mobility: 6–24″ lids; side manways on fabricated builds; skids, forklift pockets, lift lugs as required.
- Thermal: Heat-trace & insulation when freeze protection or dewpoint control matters.
Specs that Pass Audits
- Chemistry-first design: resin, SG, fittings, restraints tied to load case.
- Drawings & submittals: dimensional drawings with fitting callouts & restraints.
- Install package: hoop/band count, torque specs, pad material, anchor layout, startup checklist.
- 30+ years, 100+ mobile builds — zero spec failures.
