Important Notes:

  • All dimensions are internal (usable) dimensions
  • Volumes calculated using rectangular prism formula: L × W × H
  • Actual working capacity typically 90-95% of total volume
  • Containerised tanks engineered for ISO container compatibility (width = 2,400mm)
  • Free-standing tanks can be customised beyond standard dimensions
  • Wall thickness varies based on material, pressure, and chemical compatibility
