Since its registration in 2004, the company has undergone decades of development. The current registered capital is 10 million RMB, with a strong financial base. The office is located at No.3 Building, Tianjun Mansion, Alley 31, Anju Street, Wanjiang Community, which was fully purchased and self-constructed by the legal representative of the company for office and R&D purposes. The company now holds a patent for "Composite Scale Inhibitor, Bactericide, and Algaecide" (Patent No.: 201310******.2). In 2013, the company was granted the qualification for chemical corrosion protection construction by the China Chemical Machinery Power Technology Association under the Ministry of Chemical Industry, qualifying it as a Level 2 contractor for corrosion inhibitors, pipeline cleaning, and chemical cleaning (including non-acidic chemical cleaning + RO reverse osmosis technology). Additionally, the China Chemical Machinery Power Technology Association reviewed and issued a national general safety construction license for chemical corrosion protection to our company. In the Pearl River Delta region, due to the significant cleaning effects achieved in industrial circulating water systems, central air conditioning systems, and industrial oil circuit systems, with no corrosion or scaling after cleaning, ensuring safety, the company was designated as a regional supplier in South China by Atlas Copco (Shanghai) Trading Co., Ltd.! At the beginning of 2014, the company became a member of the China Water Treatment Association! Due to the large volume and remarkable effectiveness of air duct cleaning for central air conditioning, the company was admitted as a member of the Guangdong Indoor Environmental Health Association and obtained a C-level professional cleaning institution certification for centralized air conditioning general systems. In terms of human resources, the legal representative, Zhou Cuifang, personally holds a senior chemical inspection certificate, and the company employs one individual with a senior refrigeration certificate, two graduates with bachelor's degrees in chemical analysis, three individuals with junior refrigeration certificates, and several electricians. In the field of industrial circulating water system cleaning, the company has consistently adopted "non-acidic, neutral, environmentally friendly, and low-carbon" cleaning measures, creatively pioneering "non-acidic chemical cleaning + RO reverse osmosis technology" (ion exchange, filtration purification, online pH adjustment, real-time monitoring, etc.) to economically and environmentally address issues such as hard scale, yellow rust water, rust residue, and sludge in circulating pipelines. For special circulating water qualities (high hardness, high alkalinity, high pH), cooling towers that absorb surrounding acidic gases and smoke, mixed materials (steel, copper, aluminum alloys, special mold steel, lead alloys, etc.), and special operating conditions (year-round operation without shutdown), the company ensures that the cleaning process does not require shutdowns, and the annual water quality treatment and maintenance meet production needs and customer satisfaction. The result is that the water system operates under neutral (7.0-7.9) and softened water (hardness ≤ 200mg/l, alkalinity ≤ 200mg/l) conditions, achieving zero annual fouling thermal resistance, a steel corrosion rate ≤ 0.075mm/a, a copper corrosion rate of 0 mm/a, and no corrosion for aluminum foil and special mold steel. The conductivity and pH of the entire water system are visible, and the annual water treatment cost is lower than that of traditional chemical reagents, with no scaling or corrosion, earning consistent praise from customers. This truly demonstrates the "safe, environmentally friendly, and low-carbon" superior quality of our "non-acidic chemical cleaning + RO reverse osmosis" technology in industrial cleaning. In the area of central air conditioning water treatment, the company, relying on decades of water treatment experience and accumulated safe and reliable processes, has independently developed multiple formulas for "non-acidic, neutral, environmentally friendly, and non-corrosive" water treatment chemicals, one of which, a composite scale inhibitor, bactericide, and algaecide, has been patented. Our water treatment chemicals have a high cleaning efficiency for central air conditioning water systems, increasing the cleaning rate of insoluble scales such as sulfates and silicates from 60% (with acid washing) to over 95%, suitable for any water quality and material conditions, without environmental pollution, and applicable to various central air conditioning systems and circulating cooling water systems for scale and sludge cleaning. Additionally, the company has accumulated rich technical research and practical experience in anti-corrosion and corrosion prevention for central air conditioning water systems, elevating chemical cleaning technology to a new level. In the field of industrial oil circuit cleaning, the company has developed various heavy oil cleaners, hard scale cleaners, and aluminum fin cleaners based on different materials, oil residues (carbon deposits), and water scales, successfully cleaning oil and water scales formed during long-term operation of compressors from Atlas, Ingersoll Rand, Chongqing, and Fusheng, gaining recognition from specialized engineers. The company has been specifically designated by Atlas Copco (Shanghai) Trading Co., Ltd. as the subcontractor for all Atlas compressor water and oil circuit cleaning in the South China region. According to customer requirements, the company has also introduced highly intelligent small robots for the full-process cleaning of central air conditioning air ducts, achieving clean results approved by the Dongguan Disease Prevention and Control Center. The company also excels in central air conditioning main unit maintenance, end equipment cleaning and maintenance, and pH adjustment (7.0-8.5) of tap water, earning consistent praise and a good reputation from customers. In 2006, the company passed the ISO14001 environmental management system and ISO9001 quality management system certifications. Every task is carried out in strict accordance with the ISO9001 quality management system, ensuring standardized operations and civilized construction. In the cleaning of industrial circulating water systems, central air conditioning systems, and industrial oil circuits, the company adopts a "quantitative, timed, and assigned personnel" cleaning and management model, with clear division of labor, defined responsibilities and rights, and rapid implementation of quality checks and inspections, supported by a 1-hour quick response mobile team! The company adheres to the business principle of "customer satisfaction at the core," maintaining a service attitude of "service without limits," providing each customer with high-quality, efficient, affordable, and safe cleaning services. The company has two subsidiaries: Shenzhen Tianjun Water Treatment Technology Co., Ltd. and Dongguan Tianjun Water Treatment Mechanical and Electrical Engineering Co., Ltd., with a number of fixed clients. Its business now extends to Shanghai, Tianjin, Jiangxi, Hainan, Hunan, and Fujian provinces, enjoying a high profile and a large customer base in the Pearl River Delta region, providing excellent industrial circulating water cleaning technology to numerous enterprises with complex materials, water qualities, and operating conditions. The company's business philosophy is "neutral, environmentally friendly, professional, and honest," striving to lead in technology, increase profits through innovation, and provide high-quality, efficient, and cost-effective water treatment services to customers. The company would like to express gratitude to both new and old customers who have provided strong support and care for our business over the years.
