DR850-W-FDGO, DR350-S150-FDG specifications

Bryan Boilers is known for its premium quality heating solutions, and the DR850-W-FDGO and DR350-S150-FDG models exemplify the company's commitment to innovation and efficiency. These two models offer unique features and advanced technologies that cater to various industrial heating requirements.

The DR850-W-FDGO model is engineered as a water-tube boiler, capable of delivering high thermal efficiency while maintaining robust performance. With a maximum output of 850,000 BTUs, this boiler is ideal for large industrial applications. One of its standout features is the double-drum design, which enhances the circulation of water and steam, promoting better heat transfer and minimizing the risk of overheating. The DR850 boasts a compact footprint, making it suitable for facilities with limited space.

In terms of technology, the DR850 utilizes a unique flame retention burner designed to optimize combustion efficiency. This results in lower emissions, reducing the environmental impact and helping businesses comply with stringent regulatory standards. The DR850 is also equipped with advanced control systems that allow for precise monitoring and adjustment of temperature and pressure, ensuring optimal performance even under varying load conditions.

On the other hand, the DR350-S150-FDG model offers a slightly smaller capacity, delivering efficient heating solutions with a maximum output of 350,000 BTUs. This model is also a water-tube boiler, featuring a single drum design that provides reliable thermal performance. The DR350 is particularly noted for its quick startup capabilities, allowing for rapid heating in time-sensitive applications.

Both models share important characteristics such as durable construction designed to withstand harsh operating conditions. They are built with high-quality materials that offer longevity and reduced maintenance requirements. The integration of safety features is paramount, with both models equipped with safety shutoff systems and pressure relief valves to ensure safe operation.

In summary, Bryan Boilers’ DR850-W-FDGO and DR350-S150-FDG models are equipped with advanced technologies that prioritize efficiency, safety, and durability. With their high-output capabilities and innovative designs, they cater effectively to the needs of diverse industries, making them trusted choices for reliable heating solutions.
