The Challenge
What Sealants and Caulk Production Demands
Sealants and caulk must be heated to their flow temperature, held steady and filled into pails, tubs and containers.
The WaxMelters Solution
Waterless PRIMO Heating, Sized to the Batch
PRIMO USA stainless steel tanks are the world's fastest, even-heating, most energy efficient melting tanks: 2-3x faster melting using half the electricity, with digital temperature control and no water jacket to maintain. Add Thermal Conditioning for a stable hold, EZ-T heated transfer to feed the line, and heated filling where product goes into containers.

Frequently Asked Questions
What equipment do Sealants and Caulk manufacturers use?
Most start with a PRIMO stainless steel melting tank sized to the largest batch, add Thermal Conditioning when the material needs a stable hold, and add EZ-T heated transfer or heated filling to feed the line.
How fast does the equipment ship?
Most PRIMO tank sizes, EZ-1, AutoShot and transfer systems usually ship within 3 to 5 days. PRIMO 350 to 1000 usually ship within 7 days, and QUATTRO and OCTO usually ship within 7 to 21 days.
Can I get an application review before I buy?
Yes. Send your material, batch size, operating temperature and voltage, and the factory team will confirm sizing, options and freight with a formal quote. A mutual NDA is available.

Short answer: Sealants and caulks that must be warmed to flow need a tank that holds them at a stable temperature and viscosity, heated transfer, and a filler with a high-viscosity pump. WaxMelters recommends PRIMO Thermal Conditioning for controlled heated holding, from the PRIMO 25 TC ($2,900) to the PRIMO 1000 TC (950 gal, $37,995); heated tilting kettles such as the PRIMO 40 gal pot tipper ($6,495) for batch heating and controlled pouring; and the AutoShot ($8,495) with high-viscosity pump, or QUATTRO and OCTO, for filling pails, tubs and containers.
How to Choose Sealant and Caulk Heating Equipment
- Know the flow temperature. Standard PRIMO and Thermal Conditioning tanks run up to 212°F / 100°C; an X-Treme high-temperature configuration runs up to 400°F / 204°C, for example +$250 on the PRIMO 25 and +$1,250 on the PRIMO 1000. Heated fillers run up to 212°F / 100°C as standard, with an optional X-Treme range of up to 300°F / 149°C.
- Hold steadily. PRIMO Thermal Conditioning is built for stable viscosity and extended heated holding.
- Add agitation or recirculation where the formulation needs uniform temperature and flow.
- Plan for viscosity. EZ-1 and AutoShot offer a high-viscosity pump (+$1,000) and a variable-speed pump (+$695); QUATTRO (+$2,000) and OCTO (+$4,000) also offer a high-viscosity pump. Final specifications depend on your product, so send its details to WaxMelters to confirm the configuration.
- Choose the container. Fill ranges run 1/8 to 20, 4 to 45 and 20 to 128 oz. Send your container, including cartridges, so WaxMelters can confirm the configuration.

Which PRIMO family fits the process?
WaxMelters builds three waterless PRIMO heating families. For this industry the recommended starting point is PRIMO Thermal Conditioning. Sealants and caulks need stable viscosity and a controlled heated hold.
- Standard PRIMO melters (25 lb to 60,000 lb): efficient melting and production holding of waxes and solid ingredients.
- PRIMO Thermal Conditioning (3.5 to 7,979 gal): controlled heating and extended heated holding when stable temperature and viscosity matter most.
- PRIMO Rapid-Cycle: fast recovery when frequent reloading or repeated batches are the bottleneck.
Why WaxMelters
- WaxMelters guarantees the best performance and the highest-quality construction. Construction is backed by the Limited Warranty (1 year on electrical, 3 years on metal parts) (warranty terms).
- Industry leader and US manufacturer: every system is designed, built, tested and supported in Ronkonkoma, New York.
- Fastest melting and heating: waterless PRIMO heating is 2 to 3X faster using half the electricity.
- The most energy efficient: fast heat-up on half the electricity.
- Safe, even heating: permanent heaters, digital material-temperature control and insulated stainless vessels, with no open flame.
- Saves money, time and energy.
