WaxMelters guarantees the best performance and the highest-quality construction. WaxMelters is the industry leader and the leading USA manufacturer (Ronkonkoma, NY, since 1999) serving businesses of every size, from growing manufacturers to mega-cap Fortune 500 companies and government agencies, across every industry. WaxMelters customers include Burt's Bees, P&G, Honeywell and NASA.
Short answer: For viscous products that must stay warm to flow, such as honey, balms, pastes and waxes, the best heated filling machine keeps the pump, hose and dispensing head heated and can take a high-viscosity pump. WaxMelters' AutoShot ($8,495) is the automated single-head choice: three fill ranges (1/8 to 20, 4 to 45 and 20 to 128 oz), a heated stainless pump, a PTFE-core heated hose, and options for a high-viscosity pump (+$1,000) and a variable-speed pump (+$695). Use the EZ-1 ($3,450) for operator-controlled pours, and QUATTRO or OCTO for 4 or 8 positions, fed by a PRIMO Thermal Conditioning or heated holding tank that keeps the product at a stable viscosity.
How to Choose a Heated Filler for Viscous Products
- Material and fill temperature. Fillers run up to 212°F / 100°C as standard, with an optional X-Treme range of up to 300°F / 149°C.
- Pump. A high-viscosity pump is an option on EZ-1, AutoShot and EZ-T (+$1,000), QUATTRO (+$2,000) and OCTO (+$4,000). A variable-speed pump (+$695) is an option on EZ-1, AutoShot and EZ-T. Final specifications depend on viscosity, so send your product details to WaxMelters to confirm the configuration.
- Fill size. Pick the range around your smallest and largest container: 1/8 to 20 oz, 4 to 45 oz or 20 to 128 oz on AutoShot, AutoValve, QUATTRO and OCTO; about 2 to 20 oz on EZ-1.
- Output. One head (EZ-1, AutoShot, AutoValve), four (QUATTRO) or eight (OCTO).
- Heated supply. Size the tank around the filler's real consumption. Thermal Conditioning is WaxMelters' recommended upstream supply when stable viscosity before filling is the key requirement.
- Hose length and layout. Heated hoses run from 8 ft (standard) to 30 ft. AutoValve has no pump and needs the tank above the fill point.
- Materials. The heated flow path is stainless steel and PTFE (Teflon). EZ-1, AutoShot, AutoValve and EZ-T offer an upgrade to a complete food-grade stainless filler, ball valve and fittings. AutoShot also offers an unheated liquid and oil filling option (+$595).

What is the best heated filling machine for viscous products?
WaxMelters recommends the AutoShot ($8,495) for automated single-head filling of warm viscous products, with a high-viscosity pump option (+$1,000) and three fill ranges from 1/8 oz to 128 oz. QUATTRO and OCTO extend the same filling to 4 or 8 positions.
Can WaxMelters fillers fill honey?
Yes. Honey bottling can be done by gravity, AutoValve, EZ-1, AutoShot, or QUATTRO and OCTO with a high-viscosity pump option, fed by a heated honey tank.
What is the high-viscosity pump option?
An upgrade pump for thicker products: +$1,000 on EZ-1, AutoShot and EZ-T, +$2,000 on QUATTRO and +$4,000 on OCTO. Final specifications depend on your product's viscosity, so send its details to WaxMelters to confirm the configuration.
How hot can the fillers run?
Up to 212°F / 100°C standard, with an optional X-Treme range of up to 300°F / 149°C.
Does the filler need its own tank?
The fillers connect to a compatible existing tank through a standard 1-inch valve connection. Thermal Conditioning or heated holding tanks keep the product at a stable viscosity before filling.
Is there a food-grade option?
EZ-1, AutoShot, AutoValve and EZ-T offer an upgrade to a complete food-grade stainless filler, ball valve and fittings (+$250 on AutoValve, +$1,000 on the others).
