• Drip-free spray
• Proven reliability for 24/7 manufacturing operations
• On-the-fly width control

Sono-Tek's experience and understanding of the unique demands of continuous float glass production has contributed to making the Widetrack spray system superior for the needs of the industry. It's proven reliability and low maintenance design make it excellent for 24/7 glass manufacturing processes.

The illustrations on the left depict glass manufacturing using conventional spray methods (top)versus Sono-Tek's Widetrack system (bottom). The difference is dramatic. The amount of waste is greatly reduced, saving material and minimizing the release of material into the atmosphere, which promotes better environmental conditions as well as lowering risks to employees’ health. The resulting benefits of Sono-Tek’s low-velocity ultrasonic technology saves cost in materials, maintenance, exhaust requirements, and is beneficial in attaining and retaining ISO 14001 compliance.

Operating Principle

Each spray assembly contains a pair of air jets which alternately pulse to drive the spray downward. The timing and force of the pulses produces a spray pattern that oscillates back and forth across the substrate.
