Custom PRIMO Tank Family
Standard, Flat-Tray & Slab Processing Tanks
Standard dip tanks, shallow flat trays, deep immersion tanks, slab melters,
and multi-chamber systems are built from the same core PRIMO technology.
The configuration is determined by the usable internal dimensions, working
depth, material, temperature, part geometry, and handling method.
Submit the dimensions and process requirements below. WaxMelters will
review the application and provide the correct configuration and firm pricing.

Choose the description closest to your process. Exact dimensions and
required features are entered in the same specification form.
Standard or Deep Dip Tank
General-purpose rectangular tanks for deeper immersion, coating, treatment, and heated processing.
- Parts, tools, blocks, molds, and products
- Single or multiple chambers
- Optional screen, basket, lid, stand, and valves
Flat-Tray or Shallow Tank
Wider, lower-profile tanks for trays, broad components, cheese coating, and horizontal workflows.
- Wide usable surface area
- Shallow working material depth
- Custom support and drain arrangements
Slab Melting or Processing Tank
Built around the length, width, thickness, and loading method of slabs, bricks, blocks, or solid material.
- Standard fixed-size slab melter available separately
- Custom slab dimensions
- Optional heated discharge and valves
Engineered for rectangular geometry
Uniform Heating Requires More Than Adding Heaters to a Tank
A rectangular tank cannot be evaluated by wattage, heater size, or
vessel dimensions alone. Its geometry, heating system, temperature
sensing, controls, and insulation must be engineered to operate together.
PRIMO tanks are engineered as complete thermal systems. The heating
design is matched to the vessel geometry so the walls and corner
transitions function as active, controlled heating zones—not
slow-melting, residue-holding, or product-damaging hot spots.
Active Corner Transitions
Rectangular vessels naturally create corner transitions where material
may collect and thermal performance can become inconsistent when the
system is not properly engineered.
PRIMO strategically engineers the heating system around the complete
vessel geometry so these areas participate in the heating process
rather than being left as inactive pockets.
Controlled Material Temperature
The objective is not simply to make the tank wall hot. The system must
control the temperature of the material being processed.
Heating, sensing, insulation, and digital controls are configured
together to support consistent melting, dipping, coating,
conditioning, and holding throughout the usable tank area.
Practical Production Benefits
- More uniform heating throughout the vessel
- Reduced localized overheating
- Less slow-melting material in corners
- Improved draining and material recovery
- Easier cleaning and product changeovers
- More repeatable batch-to-batch processing

Configuration guide
What determines the final tank design?
| Requirement | Why it matters | What to provide |
|---|
| Internal dimensions | Determines usable volume, tank proportions, fabrication, and heater capacity. | Internal length × width × working depth for every chamber. |
| Material and temperature | Determines controls, heat input, construction details, and operating range. | Material name, normal temperature, and maximum temperature. |
| Part or slab geometry | Determines clearance, tank shape, screen or basket size, and loading method. | Largest item dimensions, weight, and number processed at one time. |
| Production environment | Affects stand, casters, washdown construction, controls, lids, and drainage. | Voltage, phase, washdown method, floor-space limits, and desired working height. |

PRIMO Waterless Heating vs. Water-Jacketed Construction
Both are industrial heating methods, but they solve different requirements.
WaxMelters recommends the construction that fits the material, installation,
temperature, controls, and applicable safety classification.
PRIMO Waterless Systems
- Heating is engineered around the vessel geometry and material
- No jacket water level to maintain
- No mineral scale from jacket water
- Insulated construction and digital material-temperature control
- Preferred for most standard non-hazardous applications
Water-Jacketed Systems
- Heat transfers through an intermediate water or thermal-fluid jacket
- Jacket condition and fluid level require management
- Useful when a specification or process specifically requires this construction
- Available for appropriate hazardous-location or legacy requirements
- Application review is required before selection
Performance depends on tank size, material, starting temperature, batch
load, operating setpoint, electrical service, and process conditions.
Publish quantified speed or energy claims only when supported by documented
testing for the compared configurations.
