Therm-O-Flow Guns – Dispense applicators for hot melt materials

Description

Therm-O-Flow guns

The Therm-O-Flow guns are manual and automatic dispense applicators for applying hot melt materials.

Perfect for high pressure, high flow sealant and adhesive applications, Therm-O-Flow Guns are available with electric switches so they can be used in conjunction with automated equipment.

 

Therm-O-Flow guns – Product features

  • Precise temperature control from PID control panel
  • Piston-actuated ball and seat design for positive shut off
  • Light trigger pull
  • Rugged all metal construction

The most advanced technology on the market

With throughput capability 200% better than the leading competitor, Therm-O-Flow® bulk hot melt systems from Graco outperform the competition time after time and provide the best performing industrial bulk melt systems on the market. Therm-O-Flow’s advanced temperature control capability virtually eliminates overheated material, resulting in better adhesive quality and reduced rework due to degraded material. Graco offers a complete line of Therm-O-Flow bulk hot melt systems and “point of use” melt systems – each can be configured to fit your specific application.

ADVANTAGES
