SWT 16mm 1.7MHz Glass Glaze Piezo Atomizer for Humidifiers

Overview: A High-Output Piezo Atomizer Built for Precision Humidification

For manufacturers seeking a high-power nebulization component that can deliver consistent mist output across humidification, agricultural, and landscaping systems, the 16mm 1.7MHz Glass Glaze/Ultrasonic Atomization Sheet from Gd SWT Smart Tech Co., Ltd. (Dongguan Sweetsound) — operating under the SWT brand registered in 2002 — represents a technically mature solution. This product line is positioned specifically for high-power nebulization for humidifiers and landscaping, and its 16mm variant, model ATD16-2400GSW (16mm, 1700KHz), is engineered to meet the demands of large-output applications where reliability and mist consistency are non-negotiable.

Product Specifications and Core Technology

The core of this product line centers on two key models: the ATD16-2400GSW (16mm, 1700KHz) and its larger counterpart, the ATD20-170GSW (20mm, 1700KHz). Both share the same 1700KHz (1.7MHz) operating frequency, giving buyers flexibility to select the diameter that best fits their device footprint without sacrificing the atomization frequency that defines mist particle behavior.

A defining feature of this product family is its driving method, which follows a well-defined circuit architecture: the ultrasonic humidifier circuit consists of a power supply circuit, an oscillator circuit, and a water level control circuit. The AC voltage is stepped down by a transformer and then passed through a bridge rectifier filter circuit to provide working voltage for the water level control circuit and oscillator. Simultaneously, the circuit emits corresponding frequency signals to drive the oscillator to operate. This structured driving approach ensures that the atomization sheet performs predictably once integrated into a finished humidifier or nebulization device, reducing engineering guesswork for OEM and ODM partners.

Manufacturing Excellence and Quality Assurance

SWT's ability to deliver this product at scale stems from 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 is a core differentiator: rather than sourcing ceramic elements from fragmented suppliers, SWT self-develops and self-manufactures across all processes, drawing on 25 years of cumulative experience.

The company's annual output reaching approximately 250 million units places it among the largest producers of specific piezoelectric components in mainland China. This scale is supported by over 400 sets of instruments and equipment, including large-scale automatic tunnel furnaces and automated assembly machines, ensuring that high-volume orders for atomization sheets can be fulfilled without compromising unit consistency.

For buyers in regulated markets, the glass glaze/ultrasonic atomization series matches an extensive certification set: ISO13485, ISO14001, ISO9001, IATF16949, RoHs, REACH, MDR(EU2017/745), and FDA Requirement. This certification breadth reflects SWT's broader quality infrastructure, which also includes IATF 16949:2016 automotive quality management certification (obtained in 2023) and ISO 9001:2015 and ISO 14001:2015 management system certifications company-wide.

Application Versatility: From Humidifiers to Agriculture

The glass glaze atomization sheet is not limited to household humidification. According to SWT's product documentation, this is a large output piezo atomizer for humidification systems, also applied to farms and animal husbandry. Critically, the product line is suitable for multi-head configurations, including setups with 2 heads, 4 heads, 6 heads, 8 heads, 10 heads, and 12 heads, giving system integrators the flexibility to scale mist output for anything from a single-room humidifier to a larger agricultural misting installation.

This multi-head adaptability, combined with the shared 1.7MHz frequency across the 16mm and 20mm models, allows manufacturers to standardize their driving circuitry while adjusting physical scale to match project requirements — a practical advantage for companies designing humidification systems that must serve both consumer and industrial-scale use cases.

Company Background and Industry Authority

SWT's positioning as a professional acoustics solution provider and high-tech enterprise is rooted in its focus on the R&D, manufacture, and marketing of electronic ceramic materials, smart materials, and electroacoustic transducer components. The company's stated mission — "To give everything touch and perception by providing piezoelectric ceramic ultrasonic and electroacoustic solutions" — directly informs how its atomization products are engineered, with an emphasis on precision and reliability across every process stage.

This authority is reinforced by SWT's role as a primary drafter of Chinese industry standards for buzzers, ultrasonic atomizers, and piezoelectric sensors, including official recognition from the Quality and Technical Supervision Bureau of Guangdong Province for drafting industry-wide standards for electroacoustic devices. The company has also been recognized as a National High-Tech Enterprise (China) and a Specialized and Innovative "Little Giant" Enterprise in Guangdong Province and Dongguan City, alongside a National Patent Award (Excellence Award) and 42 certified patents, including 9 invention patents.

Behind these credentials sits a dedicated technical infrastructure: SWT operates specialized centers for acoustics, nano-powder, inorganic chemistry, and electronic drive circuits, staffed by 70–85 R&D and engineering personnel out of a total workforce of over 200 people. An in-house reliability laboratory equipped for acoustic curve testing and environmental stress screening supports quality validation for products like the glass glaze atomization sheet before they reach mass production. On the service side, SWT offers sample lead times of 3–7 days and bulk production lead times of 15–20 days, with 24-hour on-site response within the Pearl River Delta region — a practical benefit for engineering teams needing rapid iteration on humidifier or misting-system designs.

Market Validation and Customer Trust

SWT's atomization and broader acoustic component history dates back to 2006, when the company began production of microporous atomization sheets, building over a decade and a half of accumulated process knowledge in ultrasonic nebulization technology. This experience has translated into long-standing commercial relationships, including partnerships with global brands such as Whirlpool, with cooperation initiated in 2010 for customized acoustic solutions across premium appliance lines — a relevant reference point for companies evaluating humidifier and appliance-integrated atomization components.

Customer feedback documented in SWT's client relationships consistently highlights the company's "professional problem-solving," "excellent quality," and "strong service awareness" as reasons behind decades-long partnerships. Combined with SWT's standing as a Guangdong Province Specialized and Innovative Enterprise recognized for high technical barriers and market leadership in professional segments, these factors position the 16mm 1.7MHz glass glaze piezo atomizer as a well-supported, technically validated component for manufacturers building humidification, agricultural misting, or animal husbandry nebulization systems that require both scale and certified quality assurance.
