Graco's Viscon heaters maintain optimal temperatures to provide consistent control of fluid viscosity. With a wide temperature operating range, Viscon heaters are excellent for any coating, sealant, adhesive or lubricant you need to pump.

Viscon HF High Flow Fluid Heaters
- Designed for high flow rates, with more power for faster material heating

Viscon HF Fluid Heaters for Explosive Atmospheres
- Developed to handle the highest viscosity coatings such as 100% solids epoxies coatings and epoxy fireproofing materials

Viscon HP High Output Fluid Heaters
- Offers high pressure (7250 psi/500 bar) for use with most pumps
