Graco Advanced Fluid Dispense (AFD), a world leader in fluid handling products and systems, announces the Therm-O-Flow® Bulk Hot Melt System, an ideal fit for both primary and secondary sealing applications in the glass industry. With material throughput capability 200 percent greater than the leading competitor, Therm-O-Flow systems have been designed to improve process efficiency and production capacity while reducing energy costs and supporting environmental initiatives.
The Therm-O-Flow 200 is available in configurations specially tailored to the glass and window industry for applying both primary and secondary seal materials. When applying the primary seal for insulated glass, the Therm-O-Flow 200 dispenses hot melt butyl to a spacer sidewall in an offline, automated process. The spacer is then sandwiched between glass panels and hot-applied desiccant or matrix material is automatically dispensed inside the spacer. For the secondary seal, hot-applied butyl material is dispensed behind the glass spacer, either manually or automatically, and around the perimeter of the insulated glass panel. Higher melt and flow rates directly improve productivity in these applications, and precision temperature controls ensure consistent processes.
Adjustable low/empty level sensors are standard on every Therm-O-Flow, so you never run out of material unexpectedly. Other features include an integrated drum air blow-off that reduces downtime by facilitating quick, easy drum changes. Easy-to-use, graphic-based control screens reduce training time, and USB data downloads allow for better process monitoring and control.
