The company covers an area of 130,000 square meters and is located within the Dezhou Economic and Technological Development Zone. It boasts advanced gas boiler product production lines and fully equipped manufacturing and processing assembly lines. With state-of-the-art, standardized, and systematic gas boiler and solar product production technologies, our products are certified from research and development to production, strictly operating in accordance with the ISO9001-2000 quality management system. The company has also achieved numerous certifications in the application of atmospheric boilers and solar products. **Product Description:** Residential Atmospheric Gas Boiler - This high-performance atmospheric cast iron boiler provides heating for homes, villas, and small commercial spaces. Equipped with an atmospheric burner, it operates silently. With an efficiency of over 92%, this product is highly suitable for installation and use in residential buildings. Unlike conventional wall-hung boilers, the atmospheric burner directly exhausts waste gases outdoors through the flue, ensuring reliable performance and low failure rates. **Product Reliability:** The boiler body is made using ductile iron casting technology, offering strong corrosion resistance and high heat exchange efficiency, with a lifespan of over 50 years. The efficient heat exchange provides rapid, stable, and balanced heat for the boiler water. The internal design of the heat exchanger plates uses baffle-style design to increase the disturbance of the boiler water, enhancing the heat exchange indicators. This allows the boiler water to heat up quickly and distribute absorbed heat more evenly, providing customers with a durable, efficient, and trouble-free operation. **Technology:** 1. Utilizes Dutch S-PRODUSTS high-precision temperature and pressure gauges. 2. Equipped with an original imported ceramic core Taco pump from the United States. 3. Features a reliable original imported (Honeywell) ignition control system. **Safety Protection:** 1. Automatic shutdown protection device: Automatically closes the internal gas valve within 60 seconds of any gas supply interruption, preventing gas leaks and ensuring that the boiler can only be restarted and returned to normal operation. 2. Over-temperature protection device: Automatically closes the internal gas valve when the boiler body temperature is abnormally high (e.g., due to insufficient water in the heat exchanger or excessive temperature regulation), providing a safety measure. 3. Fan failure and reverse airflow detection function: Automatically closes the gas valve in case of fan failure or exhaust pipe blockage and reverse airflow. The valve opens after 8 seconds once the fault is resolved and reverse airflow stops, allowing normal operation.
