Therm-O-Flow 200

The Therm-O-Flow 200 is an industrial bulk hot melt system that outperforms the competition with great production throughput, better process monitoring and reliable, efficient operation.

Improve process efficiency
Keep your production running with automatic electric crossover when using tandem units

Improve production capability
Highest throughput capability in the industry when tested and compared to leading competitor using PSA and butyl
Capable of melt rates up to 11 lb/min (5 kg/min)

Reduce energy costs
Inactivity shutoff and temperature setback reduces energy costs

Support factory environmental initiatives
Graco NXT Air Motors operate around 87 decibels while other comparable motors operate up to 103 decibels
