Best Petroleum Jelly and Ointment Melting, Holding and Filling Equipment
Short answer: Petroleum jelly, ointments and other semisolids need gentle, controlled heating to a fillable viscosity, a stable heated hold, and a heated filler with a high-viscosity pump. WaxMelters recommends PRIMO Thermal Conditioning as the starting point: the PRIMO 25 TC (26 gal, $2,900), PRIMO 100 TC (110 gal, $7,320) or PRIMO 500 TC (495 gal, $18,995). For product that is already prepared and flowable, the PRIMO heated holding and dispensing tanks run from 14 gal ($1,995) to 83 gal ($4,195). Fill jars and tins with the AutoShot ($8,495) plus high-viscosity pump, or 4 and 8 at a time with QUATTRO and OCTO.
How to choose ointment and petroleum jelly equipment
- Define the validated process window. Select temperature, residence time and agitation around the material and your documented production requirement.
- Hold without unnecessary cycling. PRIMO Thermal Conditioning maintains a stable process condition for extended holds.
- Specify cleanability. Surface finish, sanitary fittings and cleaning method are configured separately from the PRIMO heating family; include them in your request.
- 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.
- Protect the product to the point of fill. Heated transfer and a heated filling path keep the material in condition from vessel to container.

Which PRIMO family fits the process?
WaxMelters builds three waterless PRIMO heating families. For this industry the recommended starting point is PRIMO Thermal Conditioning. It is generally the starting point when stable viscosity and a controlled heated hold are required. Standard PRIMO suits compatible wax-based or solid ingredients that mainly need melting.
- 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.

What is the best heated tank for petroleum jelly or ointment?
WaxMelters recommends PRIMO Thermal Conditioning for stable heated holding of semisolids: PRIMO 25 TC (26 gal, $2,900), PRIMO 100 TC (110 gal, $7,320) or PRIMO 500 TC (495 gal, $18,995).
What is the best filling machine for petroleum jelly?
The AutoShot ($8,495) with the high-viscosity pump option (+$1,000) for automated single-head fills; QUATTRO ($29,995) or OCTO ($52,995) for 4 or 8 containers per cycle. Fill ranges run 1/8–20, 4–45 or 20–128 oz.
When is a heated holding tank enough?
When the product is already prepared and flowable and only needs to stay warm until filling. PRIMO heated holding and dispensing tanks run from 14 gal ($1,995) to 83 gal ($4,195), 800 W.
Can the tanks be configured for my cleaning requirements?
Yes. Surface finish, sanitary fittings and cleaning method are specified separately from the PRIMO heating family. Include them in your request.
How do I move ointment from the tank to the filler?
Use heated transfer such as the EZ-T ($2,995, 1, 3, 5 or 10 GPM), which offers a high-viscosity pump option (+$1,000).
