Weld-Free Construction Eliminates Leak Points

Weld-Free Construction Eliminates Leak Points

Rotationally molded from a single piece of HDPE or XLPE, the CRMI Open Top Cone Bottom Tank eliminates weld seams that fail under chemical stress. A 2.0 specific gravity rating means it handles liquids twice as dense as water without structural compromise. For operations where one leak means fines, cleanup costs, and downtime, this tank is curated to meet commercial-grade expectations. The XLPE option adds superior heat resistance, stress cracking resistance, and corrosion protection over standard HDPE. Tank Vault verifies every unit for real-world performance before listing it.

Complete Drainage Reduces Waste and Downtime

Complete Drainage Reduces Waste and Downtime

The conical bottom design channels stored chemicals directly to the 2-inch Polypro outlet fitted with an EPDM gasket. This setup enables full drainage, eliminating residual chemical pooling that leads to contamination between batches or unnecessary waste disposal costs. The open top configuration simplifies visual inspection, cleaning, and refilling without specialized equipment. Available in seven sizes from 450 to 1,750 gallons, you can match capacity to your throughput requirements without overpaying for unused volume. An optional tank stand elevates the outlet for gravity-fed dispensing into smaller containers.

Material Options Match Your Chemical Profile

Material Options Match Your Chemical Profile

HDPE provides high impact resistance and a high melting point for general chemical storage applications. XLPE upgrades performance with superior heat and chemical resistance, stress cracking resistance, and low temperature impact strength. Both materials come in natural white for easy level visibility. Choosing the right material upfront protects your investment by preventing premature tank failure and the resulting operational disruption. Tank Vault carries both variants so you can specify the exact configuration your application demands rather than settling for a one-size-fits-all approach.

Ensure Proper Fitment

Verify your facility requirements before selecting your tank size and material.

  • Requires adequate floor space for selected gallon capacity diameter
  • Verify ceiling clearance exceeds total tank height with optional stand
  • Confirm stored chemical compatibility with HDPE or XLPE material

★★★★★
“We replaced a failing welded tank with the 775-gallon XLPE model. The cone bottom drains completely between batches, and the open top makes inspection straightforward. No leaks, no stress cracks after eight months of daily use with sodium hydroxide solution. This is the kind of tank that doesn't become a problem.”
