Application-configured heated vessels for compatible processes that must intentionally reach boiling conditions, generate vapor or remove a volatile component through controlled atmospheric evaporation or distillation.

Boiling is a process requirement—not a marketing synonym for fast
Choose Rapid-Boil Only When the Material Must Reach Its Boiling Process
This category is for evaporation, concentration, vapor generation or distillation. A faster wax melter does not automatically require a rapid-boil design.
1
Atmospheric Distillation
Heat a compatible liquid to generate vapor for routing through an appropriately designed vapor path, condenser and receiver.
2
Evaporation
Remove water or another approved volatile component from a compatible process stream under controlled conditions.
3
Concentration
Increase solids or active-component concentration by removing an approved volatile fraction from the batch.
4
Water-Based Botanical Processing
Evaluate hydrosol, steam-assisted botanical or aqueous extraction workflows that use compatible materials and complete vapor handling.
The heated tank is one part of the process
Distillation Requires a Complete Vapor Path
A vessel that boils liquid is not automatically a complete or safe distillation system.
2. Vapor SpaceHeadspace, disengagement area, entrainment control and a vapor outlet sized for the process.
3. CondenserHeat-exchanger capacity based on vapor rate, inlet temperature and available cooling utility.
4. Receiver & VentingCollection vessel, nonblocked vent path, controls and safe handling of condensate and noncondensables.
Never operate a boiling process in a sealed vessel. Pressure, vacuum, flammable vapor and solvent recovery are specialized engineering scopes and are not implied by a standard atmospheric tank.

Primary goal
Typical temperature behavior
Choose when
PRIMO Thermal Conditioning
Gentle holding and viscosity stability
Remain below damaging or phase-change limits
Material is sensitive and must stay production-ready
PRIMO Wax Melter
Melt solid feedstock efficiently
Reach and hold a controlled liquid temperature
The job is phase change, not vapor generation
PRIMO Rapid-Cycle
Reduce batch and recovery time
High heat-transfer rate without intentional boiling
Throughput is limited by melt or heat recovery
Rapid-Boil
Generate vapor or remove a volatile component
Reach and sustain an approved boiling condition
Evaporation, concentration or distillation is the actual process

Initial & Final Volume
Starting gallons, desired final concentration, expected residue and allowable working headspace.
Evaporation Rate
Pounds or gallons per hour to remove, target cycle time and required production schedule.
Operating Conditions
Atmospheric, pressure or vacuum; starting temperature; boiling point; elevation and ambient conditions.
Vapor Handling
Condenser type, cooling-water temperature and flow, vapor-line routing, receiver and venting.
Foaming & Entrainment
Boil-over tendency, agitation, antifoam use, solids and need for demisting or disengagement space.
Materials of Construction
Compatibility of vessel, heater, seals, valves, gaskets, condenser and receiver with liquid and vapor.
Electrical & Facility
Voltage, phase, connected load, ventilation, area classification, utilities and local code requirements.
Required safety positioning
Rapid Boil Must Be Engineered Around the Vapor
The current page should no longer imply that one stock tank is suitable for every distillation or extraction process. Suitability depends on the complete chemistry, vapor generation rate, condenser capacity, pressure relief/vent path, controls, material compatibility and facility classification.
Standard electric equipment must not be represented as suitable for flammable solvents or hazardous locations unless specifically engineered and documented.
A boiling vessel must have an unobstructed, correctly sized vapor path.
Pressure or vacuum operation requires equipment designed and rated for those conditions.
Food, cosmetic or pharmaceutical use requires separate review of finish, fittings, sanitation, documentation and plant requirements.
Rapid-boil FAQ
Distillation and Evaporation Tank Questions
Is the heated tank a complete distillation system?
Not by itself. A complete system may require a vapor outlet, condenser, cooling utility, receiver, venting, controls, instrumentation and process-specific safety provisions.
Can this equipment be used with alcohol or other flammable solvents?
Not as a standard assumption. Flammable-solvent service requires chemical, electrical-area and code review and may require specialized equipment beyond the standard category.
Is Rapid Boil the same as a Rapid-Cycle Melter?
No. Rapid-Cycle is for fast melting or thermal recovery. Rapid Boil intentionally reaches a boiling condition for evaporation, concentration or vapor generation.
Can the vessel operate under pressure or vacuum?
Only if it is specifically engineered, fabricated, rated and documented for that condition. A standard atmospheric vessel must not be pressurized or pulled under vacuum.
How is the heater size selected?
From the batch mass, composition, sensible-heat requirement, latent heat, desired evaporation rate, heat losses, available power and process-control limits.
