Kangbeijing Plasma Online: Safeguarding Healthy Breathing with Technological Innovation — Observing Air Purification Demands in the Post-Pandemic Era through the Procurement Case of the First Affiliat

Amid the rising tide of public health demands, air purification technology has become a key safeguard for indoor environmental safety. The First Affiliated Hospital of Zhejiang University School of Medicine (FAHZU), a top-tier medical institution in China, has always prioritized the health of patients and medical staff. Its high standards and strict requirements for medical services also extend to the control of indoor air quality in the hospital. As a large comprehensive Grade A tertiary hospital integrating medical treatment, teaching, scientific research, prevention, and health care, FAHZU receives a large number of patients from all over the country every day with extremely frequent personnel flow, exposing the hospital environment to severe risks of virus and bacterial transmission. In addition, the hospital has a complex internal structure, and various wards, operating rooms, outpatient areas, and other spaces have different air quality requirements. Traditional air purification methods are difficult to meet its comprehensive and multi-level purification needs.

Against this backdrop, Kangbeijing stood out with its independently developed DBD (Dielectric Barrier Discharge) plasma technology and successfully won the bid for FAHZU's procurement project of fan coil unit plasma disinfectors. As a leading enterprise in China's plasma air purification field, Kangbeijing provided FAHZU with an innovative air purification solution featuring "no consumables, high efficiency, and human-machine coexistence" as its unique advantages.

Kangbeijing's core technology is based on the principle of DBD plasma generation. By applying voltage between two electrodes and using an insulating dielectric to block discharge, it produces high-density active particles (such as electrons, free radicals, and atomic oxygen generated by ozone decomposition). These active components can efficiently decompose pollutants such as viruses, bacteria, and formaldehyde in the air, while avoiding the hidden danger of excessive ozone in traditional electrostatic technology.

Unlike traditional purifiers that rely on filters for passive adsorption, Kangbeijing's plasma can be actively released into the air to form "ion clusters" that act continuously for hours, achieving full-space disinfection without dead corners. It is particularly suitable for crowded places such as hospitals and schools.

By precisely controlling plasma concentration, the equipment ensures that ozone generation is below the national standard of 0.1mg/m³. It adopts a washable micro-electrostatic module, eliminating the need for frequent consumable replacement and reducing long-term use costs by more than 90%.

From central air conditioning ducts in medical institutions to household ceiling-embedded equipment, Kangbeijing provides customized solutions. For example, its fan coil unit purifier has an air resistance of less than 15Pa, adapting to various air conditioning systems, and operates with extremely low noise to meet the silent needs of public places.

FAHZU's procurement project reflects Kangbeijing's irreplaceability in medical scenarios. Hospital ventilation systems need to address both virus disinfection and cross-infection risks. Kangbeijing's equipment achieves a killing rate of up to 99.9% for bacteria and viruses, and can real-time monitor operating status to ensure continuous protection.

For household users, its products integrate formaldehyde decomposition and PM2.5 filtration functions. High-energy electrons bombard pollutant molecules to decompose volatile organic compounds such as formaldehyde into harmless substances, combined with an activated carbon adsorption layer to achieve dual purification.

In the field of industrial deodorization, DBD technology can decompose odor molecules such as hydrogen sulfide and ammonia. In public places such as airports and railway stations, its ceiling-mounted purifiers can continuously inhibit pathogen transmission and reduce the risk of secondary pollution.

With the strict implementation of the "Indoor Air Quality Standard" and the improvement of public health awareness, efficient and low-consumption purification technology has become a rigid demand. Kangbeijing's "zero ozone" and "no consumables" design is in line with the national "dual carbon" goal and green consumption trends.

Kangbeijing is exploring the combination of plasma technology and the Internet of Things. For example, it enables remote control of equipment operating status through a smart APP and integrates PM2.5 sensors for real-time monitoring, promoting the transformation of equipment from "functional" to "intelligent".

By introducing German technology and achieving localized innovation, Kangbeijing has established an independent intellectual property system. Its products are exported to Southeast Asia, Europe, and other regions, becoming a typical case of "Made in China".

From medical institutions like FAHZU to thousands of households, from industrial waste gas treatment to daily breathing environment improvement, Kangbeijing's plasma technology is constantly expanding the boundaries of air purification. Today, with frequent public health incidents and increasingly prominent environmental issues, Kangbeijing's practice of safeguarding healthy breathing with technological strength has set a benchmark for the industry and demonstrated the responsibility of Chinese enterprises in responding to social needs with innovation. In the future, with the continuous deepening of technology and the expansion of application scenarios, Kangbeijing is expected to become a backbone force in the global air purification field, making greater contributions to human health.
