The ESTES EST-P Series is an advanced high-pressure leak testing system designed for empty aerosol cans, delivering highly accurate and reproducible results. An infeed star wheel guides each empty can into the test chamber. Inside, a pressure of 8 to 12 bar is applied. Even micro-leaks in the can create a measurable pressure drop within the chamber. This pressure variation is precisely detected by a high-accuracy pressure transmitter and measurement system. When a leaking can is identified, the system automatically triggers an ejection mechanism to blow the defective can out of the production line at the exit point. The entire process is fast, automated, and non-destructive, making it an excellent alternative to traditional water bath testers. The EST-P Series is the ideal replacement for traditional water bath testing, offering faster, cleaner, and more reliable performance for modern aerosol can production lines.
