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

high and low temperature, drum
low and drum empty, runaway,
and more
Automated process
integration
• Discrete I/O feature provides
remote control inputs and
outputs for integration with
other automated equipment

Point-of-Use Resin Heating
Industry Snapshot: Advanced
Composites Applications
Demand for advanced composites is growing on a global scale.
The industry wants faster cycle rates, higher capacity, and is
turning to faster curing resins to speed turnaround times.
Benefits of point-of-use resin heating
1. Heat only the resin you need – when you need it
Therm-O-Flow provides precise thermal control
with individual heat zones.
2. Reduce resin waste
Therm-O-Flow eliminates the need for conventional ovens
or drum heaters, which can cause material degradation
from heat aging.
3. Improve logistics
Therm-O-Flow delivers material directly to metering
and dispensing systems– creating a “just in time”
ready supply of thermally conditioned resins.
4. Faster cycle times
Manufacturers can use innovative, faster-curing resins
for decreased curing times – a key requirement for fast
cycle rate mass production.
