Overview: A 16mm 2.4MHz Piezo Atomizer Built for High-Output Nebulization
For manufacturers seeking a 16mm 2.4MHz high quality piezo atomizer built on glass glaze technology, Gd SWT Smart Tech Co., Ltd. (Dongguan Sweetsound) offers a purpose-engineered solution through its Glass Glaze/Ultrasonic Atomization Sheets product line. Positioned specifically for high-power nebulization, this category is designed to serve humidifiers, landscaping systems, and agricultural applications where consistent, large-volume liquid output is required. Within this line, the ATD16-2400GSW model represents the 16mm variant, engineered with the naming convention that reflects its 2400 KHz (2.4MHz) operating frequency—placing it firmly in the higher-frequency segment of SWT's atomization sheet portfolio.
This model sits alongside the 20mm ATD20-170GSW within the same product family, giving buyers a choice between compact, higher-frequency configurations and larger-diameter alternatives depending on droplet size and output volume requirements. The 16mm form factor is particularly suited to applications where installation space is limited but nebulization performance cannot be compromised.
Product Specifications and Core Features
The Glass Glaze/Ultrasonic Atomization Sheets category is explicitly positioned for high-power nebulization for humidifiers and landscaping. Beyond standard humidification, SWT documents that this large-output piezo atomizer line is also applied to farms and animal husbandry, indicating a design tolerance for continuous-duty, high-volume operating environments rather than light consumer use alone.
A defining structural advantage of this product line is its multi-head compatibility. The atomizer sheets are suitable for configurations ranging from 2 heads, 4 heads, 6 heads, 8 heads, 10 heads, and 12 heads, allowing system integrators to scale nebulization output by adding atomizer units rather than redesigning the entire liquid delivery system. This modularity is a meaningful differentiator for OEMs building humidification arrays or agricultural misting systems that need to scale output based on room size or livestock housing density.
The driving method behind these atomizers is also clearly defined in SWT's technical documentation. The ultrasonic humidifier circuit consists of three integrated subsystems: a power supply circuit, an oscillator circuit, and a water level control circuit. In operation, AC voltage is first stepped down by a transformer, then passed through a bridge rectifier filter circuit to generate the working voltage required by both the water level control circuit and the oscillator. The oscillator simultaneously emits the corresponding frequency signal needed to drive the piezo element—in this case, the 2.4MHz signal appropriate to the 16mm atomizer's resonant characteristics. This closed-loop circuit design ensures the atomizer receives a stable, correctly matched drive signal rather than an unregulated input, which is a key factor in achieving consistent mist output over extended operation.
Manufacturing Backbone: Integrated Supply Chain and Quality Systems
SWT's ability to deliver a 16mm 2.4MHz glass glaze piezo atomizer at scale is rooted in its integrated supply chain, which maintains comprehensive control over the front, middle, and rear processes of piezoelectric ceramic production—including film squeezing, casting, and dry pressing. This vertical integration means the company is not dependent on third-party ceramic suppliers for the core piezoelectric elements that drive atomization performance.
This manufacturing depth is supported by substantial physical infrastructure. SWT operates a Dongguan Headquarters spanning 24,000 square meters, housing plant, dormitory, and canteen facilities with 170 staff members, alongside a Guizhou Branch in Bijie City covering 4,000 square meters with 40 staff members. Across these facilities, the company maintains over 400 sets of instruments and equipment, including large-scale automatic tunnel furnaces and automated assembly machines. This equipment base supports an annual shipping capacity of approximately 250 million pieces for piezoelectric ceramic elements, a scale that reflects the company's standing as a massive production scale manufacturer within mainland China for specific piezoelectric components.
SWT also functions as an industrial authority in this space, serving as a primary drafter of Chinese industry standards for buzzers, ultrasonic atomizers, and piezoelectric sensors. This standard-setting role, formally recognized by the Quality and Technical Supervision Bureau of Guangdong Province, positions the company's technical specifications—including those governing atomizer sheet performance—as reference points for the broader industry rather than proprietary claims alone.
Certifications and Regulatory Compliance
Products within the Ultrasonic Atomization Series, including the glass glaze atomizer sheets, are manufactured to match a defined compliance framework: ISO13485, ISO14001, ISO9001, IATF16949, RoHs, REACH, MDR (EU2017/745), and FDA Requirement. This breadth of certification—spanning medical device quality management (ISO13485), automotive quality systems (IATF16949), environmental management (ISO14001), and both EU and US regulatory frameworks (MDR, FDA)—signals that the atomizer sheet production process is built to satisfy requirements across multiple end-use industries, not solely consumer humidification.
At the corporate level, these product-specific certifications are reinforced by company-wide credentials, including IATF 16949:2016 (obtained in 2023), ISO 9001:2015, and ISO 14001:2015, along with 42 certified patents, of which 9 are invention patents.
Real-World Application Scenarios
The documented application scope for this atomizer sheet line spans Smart Home & Appliances, where SWT supplies feedback sounders for white goods and components for USB humidifiers, as well as broader Industrial contexts. Historically, SWT's appliance-sector relationships include a long-term supplier relationship with Whirlpool, established in 2010 and maintained continuously since, supporting customized acoustic and appliance-related solutions for international markets. The company also began cooperation with Panasonic and Casio in 2005 and established a long-term supplier relationship with Sanyo in 2007, relationships that have persisted for over 18 years with what the company documents as zero-defect quality performance.
Market Validation and Client Recognition
Client feedback captured in SWT's records consistently emphasizes "professional problem-solving," "excellent quality," and "strong service awareness" as the reasons behind decades-long partnerships. The company's client roster spans multiple regions and Fortune 500 organizations, including CASIO (over 15 years of partnership), LG, Reckitt, Dyson, and CHAMBERLAIN GROUP, reflecting sustained demand across consumer electronics, home appliance, and industrial sectors. SWT has also been recognized as a Guangdong Province Specialized and Innovative Enterprise and ranks within the top 3 within its industry segment, alongside honors such as the National Patent Award (Excellence Award) and status as a National High-Tech Enterprise.
Conclusion
For buyers evaluating a 16mm 2.4MHz glass glaze piezo atomizer, SWT's ATD16-2400GSW offers a documented combination of multi-head scalability, a clearly engineered oscillator-driven circuit design, and manufacturing supported by an integrated, vertically controlled supply chain. Backed by ISO13485, IATF16949, MDR, and FDA-aligned production standards, and validated by long-standing relationships across automotive, appliance, and consumer electronics sectors, this atomizer sheet reflects SWT's broader positioning as a standard-setting supplier of piezoelectric ceramic and ultrasonic components.
