Therm-O-Flow
Bulk Hot Melt Systems
®
Therm-O-Flow. Any Hot Melt Material. Any Time.
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.
Low/Empty Level Sensors
Standard on every system.
Adjustable, so you never run
out of material unexpectedly.
Advanced Display Module
Easy-to-use, graphic-based
control screens reduce training
time. Data downloads allow
for better process monitoring
and control.
Six connection points for the 12 customer defined heat zones
Optional Light Tower
Accessory

Why Therm-O-Flow?
Improve process efficiency
• Automatic electric crossover eliminates downtime with
tandem units – you keep production running while you
change drums or pails
• Sensors signal when drums are getting low or empty,
and more material is needed
• Pump throat seals and plate seals are the only wear
components on Therm-O-Flow and can be changed
in less than one hour
• New packing and pump rod designs extend the
maintenance cycle at least seven times
• Heated platens have cast-in heaters which never need
to be replaced – and carry a lifetime warranty
• Material totalizers simplify preventive maintenance
scheduling
Improve production capacity
• Patented Mega-Flo™ Platen offers greater throughput
while reducing material waste compared to a standard
finned platen
• Eliminates need for lengthy oven melting of solid or high
viscosity resins — melts resins on demand, only what
you need
• Automatic daily startup without delay — Therm-O-Flow
is ready when the shift starts
• Use downloadable operating data to monitor and control
your process, reducing unplanned downtime and
increasing process efficiency
Therm-O-Flow 20 (5 gal)
Reduce energy costs
• Temperature setback conserves energy during
production breaks and prevents material charring
• Inactivity shutoff saves energy costs, promotes safety
and prevents material charring
Support environmental initiatives
• Built-in runaway control automatically shuts down supply
system in event of component failure or empty drum
• The quiet, low-noise NXT Air Motor operates around
87 decibels, while other comparable motors operate
up to 103 decibels
