Shenyang Baoruitong Automation Equipment Co., Ltd. was founded in 2012 and is located in Shenyang, Northeast China's traditional equipment manufacturing base. With a registered capital of RMB 5 million, the company specializes in the R&D, manufacturing, sales, and service of testing equipment. Our products are widely used in construction engineering, fire protection, HVAC, energy-saving,environmental protection, and water-saving fields. We have developed over ten product series with more than one hundred models, including building testing, HVAC testing, fire testing,coating testing, curtain wall and glass testing, and PVC pipe testing. With reliable and stable performance, our products remain highly competitive and are trusted by customers across various industries.
Are You a Manufacturer or a Trading Company?
Shenyang Baoruitong is a professional manufacturer of testing equipment, not a trading company. With more than ten years of experience in developing automated testing systems, we provide complete solutions covering product design, hardware development, software integration, manufacturing, installation, and after-sales service.
Our proprietary technologies achieve measurement precision of up to ±0.001 mm, while our modular engineering approach allows rapid customization to meet specific customer requirements. Certified under ISO 9001 and CE standards, our products are exported to more than 30 countries worldwide.
What Is Your Production Capacity?
Our company operates a standardized manufacturing facility covering 3,000 square meters, with an annual production capacity exceeding 500 units of testing equipment.
Supported by a dedicated R&D team of more than 20 engineers and specialists, we have successfully completed large-scale projects for the solar energy, building energy efficiency, and fire safety industries, ensuring reliable product quality and on-time delivery.
What Certifications Do Your Products Have and How Is Quality Ensured?
All product lines are manufactured under the ISO 9001 Quality Management System. Core testing equipment is CE certified and supported by independent third-party testing reports where applicable.
Our quality assurance process includes:
- 100% incoming raw material inspection
- Three-stage quality control during production
- Comprehensive performance testing before shipment
- 24-hour continuous operation testing to ensure stable performance
Is the Equipment Difficult to Operate? Is Training Required?
No. The equipment features an intuitive bilingual Chinese-English touch-screen interface with one-click testing procedures, making operation simple and user-friendly.
We provide free online and on-site training. Most users can operate the equipment independently within one to two days. Detailed user manuals, video tutorials, and remote technical assistance are also available whenever support is needed.
Are Operating Costs High? Is Maintenance Complicated?
Operating costs are low thanks to energy-efficient hardware that typically consumes around 30% less power than comparable industry equipment.
Daily maintenance is straightforward. The modular design allows quick replacement of components and consumables, while routine maintenance generally involves only basic cleaning and periodic consumable replacement.
We provide comprehensive maintenance documentation and lifetime technical support to ensure long-term equipment reliability and performance.
