Therm-O-Flow Supply Systems
Graco Online Training – TOF Supply Systems • • System Overview Pump Selection • • System Identification Electronics • • Platen/Wiper Selection Tandem Systems • • Ram Selection Accessories Improve Process Efficiency – Automatic electric crossover eliminates downtime with tandem units – keep your production running while drums/pails are being changed. – 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 preventative maintenance scheduling. Improve Production Capacity – Patented Mega- Flow™ 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 – User downloadable operating data to monitor and control your process, reducing unplanned downtime and increasing process efficiency. Reduce Energy Costs – Throughput capability 200% greater than the leading competitor. – 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.
