Which PRIMO System Is Right for Your Process?

Start with what your material and production process actually require. The standard PRIMO platform handles a wide range of wax, honey and compatible heated-process applications. Thermal Conditioning and Rapid-Cycle systems are selected when the process requires a different thermal priority.

Important: Thermal Conditioning is not the “food-grade version” of a PRIMO. Standard PRIMO equipment is already used for compatible food-contact waxes, beeswax, honey, cosmetic waxes and other applications. Thermal Conditioning is selected only when the thermal behavior of the process requires a more specialized conditioning and holding approach.
Start With the Process Requirement

Three PRIMO Thermal Priorities

Capacity naming may change by industry, but the underlying equipment selection should be based on the material, required heating rate, holding requirements and production cycle.

Standard PRIMO
PRIMO Melter / Wax Melter

For Melting, Heating and Production Holding

The standard PRIMO platform is the starting point for most compatible wax, honey and general heated-process applications. It efficiently melts or heats material and maintains the required operating temperature for production.

Best For
  • Solid wax melting
  • Batch melting and reheating
  • Honey warming and processing
  • Production holding
  • Supplying pouring, pumping or filling equipment
Common Applications
Candle wax Beeswax Honey Cheese wax Depilatory wax Cosmetic wax Paraffin Soy wax

Specialized Conditioning
PRIMO Thermal Conditioning

For Gentle Conditioning and Extended Precision Holding

Select Thermal Conditioning when the process requires greater moderation of heat input, extended holding, viscosity stability or protection of a temperature-sensitive formulation.

Best For
  • Long heated holding periods
  • Temperature-sensitive formulations
  • Viscosity-critical materials
  • Materials susceptible to scorching or separation
  • Staging before pumping, filling or transfer
Common Process Examples
Chocolate Creams Lotions Emulsions Specialty formulations Viscosity-sensitive compounds

Maximum Cycle Speed
PRIMO Rapid-Cycle

For High Throughput and Short Recovery Cycles

Select Rapid-Cycle when production speed is the dominant requirement and the material is compatible with the system's higher-intensity heat-transfer approach.

Best For
  • Repeated production batches
  • Very short recovery targets
  • Continuous or frequent material loading
  • High-throughput operations
  • Compatible robust process materials
Common Process Examples
High-volume wax Recovery processes Industrial compounds Fast batch production

Capacity Naming

Pounds or Gallons? Use the Language of the Industry.

Capacity terminology is a merchandising convention and does not necessarily indicate a different PRIMO heating platform.

Candle & Wax Production

Size Primarily by Pounds

Candle manufacturers traditionally purchase melters by approximate wax weight, so PRIMO candle and general wax-melting models should continue to use familiar pound-based model names.

Gallon vessel capacity can still be shown as a secondary specification.

Honey & Beekeeping

Size Primarily by Gallons

Honey and beekeeping customers generally work in vessel volume. These systems can use the same standard PRIMO heating technology while being marketed and selected by gallons.

A gallon-based model name does not mean the unit requires Thermal Conditioning.

Thermal Conditioning

Size by Working Gallons

Thermal Conditioning systems serve many materials with different densities. Gallons provide the clearest basis for working volume, headspace, mixing, drawdown and downstream process requirements.

Standard PRIMO vs. Thermal Conditioning Is a Process Decision

Beeswax does not require Thermal Conditioning. Honey does not require Thermal Conditioning. A food-contact or cosmetic application does not automatically require Thermal Conditioning either. Standard PRIMO systems can serve these applications when the standard heating profile is appropriate. Thermal Conditioning is reserved for processes that specifically benefit from gentler conditioning, longer precision holding or greater control of material condition.

Side-by-Side Selection

Compare PRIMO System Priorities

On mobile, each system remains a full-width card instead of forcing the customer to scroll sideways through a comparison table.

Standard PRIMO

Primary Objective Efficient melting, heating and production holding
Starting Material Solid, semisolid or compatible liquid material
Production Rhythm Batch melting, holding, pumping, filling or transfer
Sizing Basis Market dependent: pounds for candle/wax applications; gallons for honey, beekeeping and volume-based process markets
Typical Starting Point Choose Standard PRIMO unless the process specifically requires gentler conditioning or accelerated recovery.

Thermal Conditioning

Primary Objective Condition, stabilize and hold material
Starting Material Liquid, semisolid, softened or formulated material
Production Rhythm Extended holds, staging, pumping and filling-line supply
Sizing Basis Working gallons plus required headspace and process reserve
Typical Starting Point Choose when material sensitivity or long-duration conditioning matters more than maximum melt rate.

Rapid-Cycle

Primary Objective Minimize recovery time and maximize throughput
Starting Material Application-compatible material able to tolerate higher heat transfer
Production Rhythm Frequent loading, repeated batches and short turnaround
Sizing Basis Batch load, feed rate, recovery target and hourly throughput
Typical Starting Point Choose only when cycle time is a major production constraint.
Quick Selection Path

Start With Standard PRIMO, Then Evaluate the Process

1
What material are you processing? Identify the material, its starting form, density and operating temperature.
2
Will standard PRIMO heating meet the process? For most wax, beeswax, honey and compatible heated-process applications, Standard PRIMO is the starting point.
3
Does the process require gentler conditioning? Evaluate Thermal Conditioning when long holds, viscosity stability, formulation sensitivity or controlled heat input are important.
4
Is production recovery the limiting factor? Evaluate Rapid-Cycle when reducing batch recovery time can materially increase production.
Separate Process Family

Rapid Boil Is Not Rapid-Cycle Melting

Rapid-Cycle systems are designed to shorten melting or thermal recovery cycles. Rapid-Boil equipment is used when the process intentionally reaches boiling conditions for compatible evaporation, concentration, recovery or distillation operations.

Application & Safety Review

Processes Requiring Engineering Review

Flammable or solvent-bearing materials, pressure, vacuum, classified locations, reactive chemistries, unusual sanitation requirements and materials that may degrade or plate onto heated surfaces require an application and safety review.

PRIMO Selection FAQ

Common PRIMO System Questions

Is Thermal Conditioning the food-grade version of PRIMO?

No. Thermal Conditioning describes the thermal-processing configuration, not whether the equipment is food grade. Standard PRIMO systems are also used in compatible food-contact, honey, beeswax and cosmetic applications.

Do honey or beeswax applications require Thermal Conditioning?

No. Standard PRIMO equipment is used for honey and beeswax processing. These systems may be marketed by gallons because that is how those industries commonly specify tank capacity.

Why are some PRIMO models described in pounds and others in gallons?

Different industries purchase equipment differently. Candle manufacturers commonly describe melting capacity by pounds of wax, while honey, beekeeping and many general process applications are normally specified by gallons. The capacity terminology does not by itself indicate different heating technology.

When should I choose Thermal Conditioning?

Choose Thermal Conditioning when your production process specifically requires more moderated heat input, prolonged heated holding, viscosity stability or protection of a temperature-sensitive formulation.

Is Rapid-Cycle automatically better because it is faster?

No. Rapid-Cycle is most useful when recovery time is a significant production constraint and the material is compatible with the higher-intensity heat-transfer approach.

Can a standard PRIMO both melt and hold material?

Yes. Standard PRIMO systems are designed for melting or heating and controlled production holding. Separate conditioning or day tanks may become useful when production volume, line uptime or formulation requirements justify a dedicated second vessel.
