Every tool we build for specifying equipment lives here. Run your cursor down the list — each one opens up to show what it covers and what it hands back — then click the one that matches your project. All four are free, need no login, and end in a bill of materials or sizing sheet you can send straight to our engineers.
Field-erected bolted, welded & concrete tanks
Spec a tank that gets built on site. Six steps walk from the offering and coating system through service, diameter and sidewall height, roof type, foundation, the nozzle schedule, and the appurtenances that go on the shell — ladders, platforms, mixers, level instruments.
Ends in a bill of materials and budget summary
Shop-fabricated EnviroBox units on a fixed 8′ width
For tanks that arrive built instead of being erected. The 8-foot module width is fixed, so you set length and height, then material, roof, nozzles, and accessories. Pick this one when the delivery date matters more than hitting an exact diameter.

Doda chopper pumps, mixers, aerators & separators
The rotating equipment that moves and conditions whatever is in the tank. Start from the machine — chopper or transfer pump, propeller or digester mixer, aerator, screw separator — then set drive and power, wetted materials, mounting, and options against your actual service conditions.
Ends in an equipment sheet you can add to a quote
Live 3D sizing with heat, mixing & gas balance
Less a shopping cart than a sizing bench. Drag diameter and sidewall height and the downstream numbers move with them — working volume, feed rate and retention time, biogas yield, heat demand, insulation, mixing power — alongside a 3D model of the shell you are describing.
Ends in a sizing envelope with heat and gas figures
Not sizing equipment? Three more tools sit alongside these: the Lifecycle Cost Calculator for 50-year net present value across tank types, the Why Tanks Fail diagnostic for reading symptoms on a tank you already own, and For Specifying Engineers for editable CSI spec sections and sizing tables.
