PRIMO Soap Production Tanks
Stainless steel waterless production tanks for heating and holding
oils, fats, tallow, butters, glycerin, melt-and-pour soap bases and
compatible heated formulations.
Choose by gallons.
Start with the largest working batch, then allow for required headspace,
mixing displacement, ingredient additions and future production growth.
What Changes the Recommended Size?
Working Batch
Use the largest batch expected during normal production.
Headspace & Mixing
Do not assume total vessel capacity equals recommended working volume.
Daily Production
Refill frequency, batches per shift and downstream use can justify
additional capacity.
Why Soap Manufacturers Choose Waterless PRIMO
No Jacket Water. No Routine Replacement Heaters.
PRIMO Soap Production Tanks have no jacket-water reservoir and use a permanent heating system designed for long service life without
routine replacement heaters under normal intended operation.
No Jacket Water to Maintain
No separate water reservoir to fill before operation, monitor for
proper level or replenish as part of normal water-jacket operation.
Permanent Heating System
PRIMO's heating system is designed to remain
part of the equipment.
Explore Total Operating Requirements
Review connected heating power, footprint, capacity, operating time,
jacket-water requirements and long-term service considerations—not
purchase price or gallons alone.
Ready to choose a PRIMO soap production tank?
Review the same working gallons, material, starting and target
temperatures and process-ready endpoint. Then review the equipment
architecture, connected power, facility footprint and maintenance requirements.

Quick PRIMO Soap Production Sizing
Find Your Current Fit & Growth Fit
Enter the largest working batch you run today.
The calculator provides a current-fit starting point and a larger
growth-oriented PRIMO Soap Production model.
Quick sizing uses a 20% planning allowance above the entered working
batch to provide room for normal operating headspace.
Final equipment selection should also consider formulation behavior,
ingredient additions, mixing or agitation displacement, foaming,
heating requirements, electrical service and downstream production demand.

Model designation is the nominal Soap Production class. Physical vessel
capacity may differ slightly from the model number. Working volume may be
lower depending on headspace, formulation, agitation and process requirements.
