Pick your method. We will point you to the tanks, kettles and filling equipment that method actually uses, so you are not guessing from a parts list.
Bar soap, no cook
Blend your heated oils with lye solution, bring to trace, then pour to mold. No cook. You need a way to melt oils, mix the batch and prep lye safely.
Oil melting · Batch mixing · Lye prep
Bar soap, cooked
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.
Heated cook · Mix & tilt · Lye prep
Uses KOH, not NaOH
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.
Heated cook · Dilute & hold · Bottle filling
Pre-made base, no lye
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.
Base melting · Hold at temp · Mold filling
| Your method | What the process needs | Equipment |
|---|---|---|
| Cold ProcessBar soap, no cook | Melt oils and fats, mix in lye solution to trace, pour to mold | Production Tanks, Lye / NaOH Tanks, Mixing & Tilting Kettles |
| Hot ProcessBar soap, cooked | Cook the batch with heat, then mold | Mixing & Tilting Kettles (heated), Lye / NaOH Tanks, Production Tanks |
| Liquid SoapUses KOH, not NaOH | Cook paste, dilute, hold, then bottle | Complete Systems, Filling & Transfer, Production Tanks |
| Melt & PourPre-made base, no lye | Melt base, hold at pour temp, fill molds or containers | Complete Systems, Filling & Transfer, Production Tanks |
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.
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.
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.
No separate water reservoir to fill before production, monitor for proper level or replenish as part of normal water-jacket operation.
PRIMO uses permanent heating elements designed so routine replacement heaters are not required under normal intended operation.
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.
Open any topic below for sizing, workflow and selection detail.
The best equipment decision begins with the actual production constraint, including the heating method itself. Use these questions as a quick production self-assessment.
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.
Heat-up time · Jacket thermal mass · Process-ready time
Why Waterless PRIMO? →Do not review heater wattage alone. Review connected heating power, measured or modeled kWh, operating time, footprint and the same production requirement.
Connected kW · kWh · Facility cost
Run the PRIMO Savings Calculator →If ingredient incorporation or emptying the vessel consumes too much labor, evaluate powered mixing or tilting equipment.
Mixing · Batch uniformity · Discharge
Explore Mixing Equipment →If operators move product in pitchers, pots or buckets, connect the production vessel to heated transfer or filling equipment.
Less handling · Heated flow path · Cleaner workflow
Choose Filling / Transfer →If heated material is ready faster than it can be dispensed or packaged, the downstream filling step, not the tank, may be limiting daily output.
Fill rate · Container size · Automation
Explore Filling Systems →If capacity, connected power, equipment footprint or disconnected production steps are constraining growth, evaluate the system as a whole.
Growth · Footprint · Line balance
Build a Complete System →Soap Production models are selected in gallons. Use this quick tool as a starting point before reviewing headspace, mixing, recovery and downstream demand.
Enter the working volume you run today. The calculator provides a current-fit starting point and a larger growth-oriented PRIMO Soap Production class.
Soap manufacturing can involve several separate thermal and material-handling steps. Build only the stages your formulation requires, then connect them as production grows.
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.
Use the same engineering and production-planning tools across the Soap Production equipment line.
Review gallon capacity, practical headspace, current production and future growth.
Size a Soap Production Tank →Review footprint, connected heating power, capacity and facility economics against another system.
Run the PRIMO Savings Calculator →Determine whether the downstream process requires operator dispensing, measured filling, heated transfer or a combination.
Choose the Right System →Review the complete installed and supported system, not only the advertised equipment price.
Purchase from the company that designs, manufactures and supports the equipment.
Qualifying equipment may be eligible for Section 179 or bonus depreciation

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.
Start with the largest working batch in gallons, then account for practical headspace, mixing displacement, ingredient additions, daily production and expected growth. Capacity is not automatically the recommended working batch.
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.
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.
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.
Use the dedicated Lye / NaOH equipment section. Caustic-solution equipment requires review of concentration, wetted materials, seals, valves, working volume and facility handling procedures.
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.
Upgrades and options (such as X-Treme high temperature, longer hoses and other add-ons) usually ship within 7 days.

Melt a ready-made base, hold at pour temperature, fill molds or containers. No lye handling. Start with a PRIMO soap production tank and add heated filling when volume grows.
Melt oils, mix in NaOH solution to trace, pour to mold. You need oil melting, safe lye prep and batch mixing. Pair soap tanks, lye tanks and tilting kettles.
Same start as cold process, then cook with heat before molding. A heated tilting kettle is the workhorse so you can mix and tip without a second pour vessel.
Cook paste (often KOH), dilute, hold and bottle. Plan heated tanks plus soap filling or melt and pour machines.
Discount Soap Equipment, SoapEquipment and Willow Way mainly sell water-jacketed oil tanks in roughly 6 to 125 gallon classes, with jacket water to maintain and, on some builds, multi-week lead times. WaxMelters manufactures waterless PRIMO soap tanks in a far wider gallon range, adds heated tilting kettles that heat-mix-pour in one vessel, heated lye tanks, and heated filling and transfer that finish the line. Facts already on this site: USA built in Ronkonkoma, NY since 1999, BBB A+, customers from growing makers to Fortune 500s, government agencies and NASA.
WaxMelters PRIMO soap production tanks are the shortlist pick when you want USA-built waterless stainless tanks with digital control, published sizes from bench to plant scale, and the same factory for mixing, lye and filling.
Size to your largest working batch, then allow headspace for mixing and additions. Small shops often start in the PRIMO 3 to PRIMO 25 range. Growing daily production moves into PRIMO 50 to PRIMO 500. See the soap tank sizing guide and product cards for gallons and prices.
If you want to avoid jacket water maintenance and faster heat-up on less connected power, choose waterless PRIMO. If a specification requires a water jacket, WaxMelters also builds PW water-jacketed tanks. Most soap makers choosing WaxMelters pick PRIMO.
Yes. PRIMO tanks melt and hold melt-and-pour base, oils, butters and many lotion-related phases. For thick fills, add heated filling or transfer rather than relying on a cold ball valve alone.
Tell us your method (melt and pour, cold process, hot process or liquid), largest batch gallons and what you fill into. We will point you to the real PRIMO models and options.
