Soap tank sizing

Size Soap Tanks to Working Batch and Method

Soap production tanks should fit your largest oils/butter or melt-and-pour batch with mixing headspace. Pair tanks with lye prep, tilting kettles or heated fill as the method requires.

01

Melt-and-Pour

PRIMO melt and hold sized to pour sessions.

02

Cold / Hot Process

Oil melt tanks plus lye and tipping capacity.

03

Liquid Soap

Plan cook, dilute, hold and bottle volumes.

04

Growth

Leave a clear next tank size when daily batches rise.

Process temperature and viscosity

What Viscosity Means Here

Soap and lotion viscosity at process temperature decides when heated fill is required. Size the tank for batch mass first.

01

What It Is

Thickness at the temperature you melt, hold, dip, transfer or fill.

02

Why Heat Matters

Heat lowers viscosity so material moves without setting in tanks, hoses or heads.

03

What We Size

Tank, voltage, dip chamber or heated path around viscosity at operating temperature.
