Soap Production Equipment
Heating, Mixing, Transfer & Filling Systems for Soap Manufacturers
Improve the part of soap production that is limiting output.
Start with ingredient heating, soap production tanks, mixing,
lye preparation, heated transfer, filling or a complete integrated system—
then size the equipment around your formulation, working gallons and daily production.
Same start as cold process, but you cook the batch with heat to drive saponification, then mold. The workhorse is a heated tilting kettle you can mix in and tip out.
Cook the paste, dilute it, then bottle. Built around KOH, not bar-soap lye. You need heated tanks to cook and hold, plus filling to fill bottles cleanly.
Melt a ready-made base, add color and scent, pour to mold. No lye handling. You need a clean melter to hold base at pour temp and equipment to fill molds or containers.

One note on lye. Cold and hot process bar soap use sodium hydroxide (NaOH). True liquid soap uses potassium hydroxide (KOH). Our Lye / NaOH tanks are built for caustic-solution prep either way. Tell us which you run and we will spec it right.
A Different Soap-Tank Heating Architecture
Why Soap Makers Choose PRIMO Waterless Soap Tanks
PRIMO soap tanks heat with no jacket-water reservoir. Before choosing by price or gallons alone, review heat path, connected heating power, footprint, usable capacity and operating requirements.
The best equipment decision begins with the actual production constraint—including the heating method itself. Use these questions as a quick production self-assessment.
Waiting for the Tank—or Jacket Water—to Heat?
If production is delayed while a jacket and the material come up to process temperature, review the complete heat-up path and time to process-ready condition.
Do not review heater wattage alone. Review connected heating power, measured or modeled kWh, operating time, footprint and the same production requirement.
PRIMO Soap Production Tanks have no jacket-water reservoir and use
permanent heating elements designed to remain part of the
heating system under normal intended operation.
01
No Jacket Water to Fill or Maintain
No separate water reservoir to fill before production,
monitor for proper level or replenish as part of normal
water-jacket operation.
02
Permanent Heating Elements
PRIMO uses permanent heating
elements designed so routine replacement heaters are not required
under normal intended operation.
03
Explore the Complete Operating Cost
Review more than purchase price and gallons. Review connected
heating power, footprint, usable capacity, operating time and long-term service considerations.
Choosing a PRIMO soap production tank?
PRIMO soap production tanks have no water jacket to heat, maintain or service. They use permanent heating elements while
digitally controlling the temperature of the production material.

The calculator provides a current-fit starting point
and a larger growth-oriented PRIMO Soap Production class.
Planning tool only. Final equipment selection should also consider
material behavior, practical headspace, mixing or agitation,
heating requirements, available electrical service and downstream production demand.
Build the Production Workflow
From Raw Ingredients to Controlled Filling
Soap manufacturing can involve several separate thermal and
material-handling steps. Build only the stages your formulation requires,
then connect them as production grows.
1
Heat
Oils, fats, tallow, butters or soap base
2
Prepare / Mix
Incorporate ingredients and formulate the batch
3
Hold
Maintain required process temperature
4
Transfer
Move material without repeated manual carrying
5
Fill
Supply molds, containers or downstream packaging
Do not size only the tank.
A larger production vessel does not solve the problem if mixing,
transfer or filling is already slower than upstream heating.
Size the equipment around the complete production sequence.
Production Planning Tools
Size, Configure and Plan the System
Use the same engineering and production-planning tools across
the Soap Production equipment line.
Soap Production Tank Sizing
Review gallon capacity, practical headspace,
current production and future growth.
Start with the largest working batch in gallons, then account
for practical headspace, mixing displacement, ingredient additions,
daily production and expected growth. Physical vessel capacity is
not automatically the recommended working batch.
Can these tanks heat oils, fats, tallow and butters?
PRIMO Soap Production Tanks are intended for compatible heated
soap-production ingredients including oils, fats, tallow, butters,
glycerin and melt-and-pour soap bases. Final configuration should
match the material, temperature and viscosity.
Do I need a Soap Production Tank or a mixing kettle?
Choose a production tank when the primary requirement is heating,
melting or holding. Evaluate a mixing tank or tilting kettle when
active ingredient incorporation, batch uniformity or controlled
batch discharge is a major part of the process.
Can filling equipment connect directly to the Soap Production Tank?
Many configurations can supply dispensing, heated transfer or
filling equipment from the production vessel. Valve size, viscosity,
temperature, pump requirements and downstream consumption should be reviewed.
What if I need lye / NaOH processing equipment?
Use the dedicated Lye / NaOH equipment section. Caustic-solution
equipment requires review of concentration, wetted materials,
seals, valves, working volume and facility handling procedures.
Can I start with one machine and expand later?
Yes. A production system can begin with ingredient heating or
a Soap Production Tank and later add mixing, transfer, dispensing
or filling as the bottleneck moves downstream.
Tell Us What You Make and Where Production Slows Down
Send the formulation or material type, largest working batch in gallons,
operating temperature, current process, daily output and production goal.
We will help identify the appropriate tank, mixing, transfer, filling
or complete-system configuration.
