Customized sealed non-contact ultrasonic atomization spraying is precision equipment designed for cleanrooms, vacuum chambers, or environments requiring strict isolation from samples. Utilizing ultrasonic transducers for micrometer-level atomization, it delivers droplets to target surfaces through non-contact methods. The sealed atomization chamber prevents cross-contamination and external environmental influences, making it ideal for high-cleanliness applications in semiconductors, microelectronics, optical films, pharmaceuticals, and biomaterials.

• Sealed Isolation: Complete atomization chamber with sealed design supporting evacuation and nitrogen purging. Features quick-opening doors, visible windows, and sealed flange interfaces (CF/KF or customized) for clean room and vacuum requirements.
• Non-contact Spraying: Ultrasonic atomization creates stable mist flow guided to workpiece surfaces by controlled airflow or electric field. Eliminates nozzle-to-workpiece contact to prevent surface damage and cross-contamination.
• Micron-level Droplet Control: High-frequency transducers (optional 100 kHz, 110 kHz, 120 kHz) combined with precision liquid supply achieve micrometer-level atomized particles adjustable by solvent and process requirements.
• Vacuum/Inert Atmosphere Operation: Supports operation from atmospheric pressure to low vacuum (10⁻²-10³ Pa, customizable range) with nitrogen or argon purging for oxygen-sensitive or volatile solvent systems.
• Precise Liquid Supply & Flow Control: Micro injection pump with flow range from µL/min to mL/min. Supports pulse or continuous liquid supply with liquid level detection and anti-dry operation protection.
