Product Overview
The 16mm 2.4MHz piezo atomizer of glass glaze, identified under the model code ATD16-2400GSW, belongs to the Glass Glaze/Ultrasonic Atomization Sheets product line manufactured by Gd SWT Smart Tech Co., Ltd.(www.swt99.com), operating under the brand name SWT (Dongguan Sweetsound). This product line is positioned around high-power nebulization for humidifiers and landscaping, and the 16mm variant is engineered as a large output piezo atomizer designed to meet the demands of humidification systems as well as agricultural applications such as farms and animal husbandry. For buyers researching compact, high-throughput atomization components, this model represents a specialized entry point into SWT's broader ultrasonic atomization portfolio, distinguishing itself from the company's medical-grade microporous mesh atomizers by focusing on volume output rather than micron-level particle precision.
Technical Specifications and Driving Method
At its core, the ATD16-2400GSW carries a 16mm form factor, with the "2400" designation in its model code reflecting its 2400 kHz (2.4MHz) operating frequency — a key differentiator from the companion ATD20-170GSW model, which is sized at 20mm. This frequency positioning is central to how the atomizer converts electrical energy into fine mist output for humidification and horticultural use.
The driving method behind this atomizer follows a structured circuit design: the ultrasonic humidifier circuit consists of a power supply circuit, an oscillator circuit, and a water level control circuit. In operation, AC voltage is stepped down by a transformer and then passed through a bridge rectifier filter circuit, which supplies the working voltage needed for both the water level control circuit and the oscillator. The oscillator simultaneously emits the corresponding frequency signals required to drive the piezoelectric element, enabling consistent and controlled nebulization output.
Manufacturing Process and Supply Chain Integration
SWT's approach to producing glass glaze atomization sheets reflects the company's broader manufacturing philosophy of integrated supply chain control, covering front, middle, and rear processes of piezoelectric ceramic production. For thin sheet formation, the company applies tape casting (flow casting), while thick sheet formation relies on dry pressing. The complete processing sequence includes squeezing, laminating, sintering, polarizing, and automated testing — a self-developed and self-manufactured workflow accumulated over 25 years of cumulative experience.
This full-chain capability is supported by substantial production infrastructure: SWT operates over 400 sets of instruments and equipment, including large-scale automatic tunnel furnaces and automated assembly machines, contributing to an annual shipping capacity of approximately 250 million pieces for piezoelectric ceramic elements. This scale of production infrastructure underpins the company's ability to serve high-volume humidifier and atomization component orders consistently.
Application Scenarios: Humidification, Agriculture, and Multi-Head Systems
The glass glaze atomization sheet category, including the 16mm 2.4MHz variant, is specifically suited to humidification systems and has also found application in farms and animal husbandry. A notable feature of this product line is its adaptability to multi-head configurations, supporting setups with 2, 4, 6, 8, 10, or 12 heads, allowing integrators to scale nebulization output according to the size of the humidification or agricultural environment being served. This multi-head compatibility positions the ATD16-2400GSW as a flexible component for system designers who need to match atomization capacity to variable spatial or throughput requirements, whether in residential humidifiers, greenhouse landscaping systems, or livestock housing environments.
Within SWT's broader business scope, this aligns with the company's coverage of Smart Home & Appliances, where feedback sounders and humidification components serve white goods and USB humidifiers, as well as Industrial & Maritime contexts involving ultrasonic-based sensing and output components.
Quality Certifications and Compliance Standards
Products within SWT's ultrasonic atomization series, including the glass glaze atomization sheets, are matched against a defined set of compliance standards: ISO13485, ISO14001, ISO9001, IATF16949, RoHS, REACH, MDR (EU2017/745), and FDA Requirement. This certification framework reflects the company's IATF 16949:2016 Automotive Quality Management System certification obtained in 2023, alongside its long-standing ISO9001 and ISO14001 certifications first obtained in 2003, providing buyers with a documented compliance foundation when evaluating supplier reliability.
R&D Capabilities Behind Piezoelectric Ceramic Production
The atomization sheet's underlying piezoelectric ceramic material benefits from SWT's dedicated Dongguan Piezoelectric Ceramic Research Center, which focuses on breaking through traditional empirical manufacturing limitations through artificial intelligence, machine learning, and high-throughput computing. Supporting technologies developed within this research framework include an intelligent piezoelectric ceramic manufacturing system built on a "perception-decision-execution" closed loop, an in-situ sintering shrinkage testing system capable of contactless dimension monitoring from room temperature to 1250°C with a sampling frequency of 1 Hz, and an embodied intelligent agent for piezoelectric ceramic powder weighing that achieves batching precision of ±0.05% with an average prediction error of only 1.60%. These capabilities collectively support consistency in the ceramic materials that feed into finished atomization products like the ATD16-2400GSW.
Company Background and Industry Standing
Gd SWT Smart Tech Co., Ltd. traces its production roots to 1991, when it commenced professional buzzer production and technology accumulation, later adopting the SWT brand name in 2002 upon relocating to Dongguan City. The company began production of microporous atomization sheets in 2006, marking its entry into the ultrasonic atomization category that the glass glaze product line now extends. Over time, SWT has been recognized as a National High-Tech Enterprise, a Specialized and Innovative "Little Giant" Enterprise in Guangdong Province and Dongguan City, and a recipient of the National Patent Award (Excellence Award) as well as the Dongguan Excellent Patent Award. The company also serves as a draft unit for China Electronic Components Association standards, including official drafting responsibilities for "Piezoelectric Sounders and Piezoelectric Buzzers" and "Electromagnetic Sounders and Electromagnetic Buzzers" standards.
Client feedback documented by the company highlights SWT's "professional problem-solving," "excellent quality," and "strong service awareness" as recurring reasons cited for decades-long partnerships across automotive, consumer electronics, and home appliance sectors.
Conclusion
For buyers seeking a 16mm 2.4MHz piezo atomizer of glass glaze construction, the ATD16-2400GSW from SWT offers a combination of defined technical specifications, a documented driving circuit design, multi-head scalability for humidification and agricultural applications, and a manufacturing foundation built on integrated supply chain control, substantial production capacity, and continuous R&D investment in piezoelectric ceramic materials. Backed by compliance credentials spanning ISO13485, IATF16949, RoHS, REACH, MDR, and FDA requirements, this product line reflects SWT's accumulated experience in ultrasonic atomization since entering the category in 2006.
