Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Thanks to its innovative design and unique structure, the vacuum boiler boasts dual hot water outputs. This versatile marvel provides hot water at varying temperature levels simultaneously, utilizing either a dual-circuit or single-circuit system. These systems can function independently, offering unparalleled flexibility in application.
High thermal efficiency: Experience superior energy efficiency with our heat exchanger that circulates within a completely sealed vacuum chamber. Crafted from high-grade imported stainless steel, it ensures exceptional heat transfer efficiency. This results in reduced energy consumption, promoting significant energy savings.
Absolute safety: Engineered for safety, the boiler operates under constant negative pressure, eliminating explosion risks. It is fortified with an array of safety features, including temperature sensors, safety valves, overheat protection, and vacuum control switches. These comprehensive safety measures address all potential hazards, ensuring peace of mind.
Intelligent control: Our cutting-edge control system features digital management, an advanced LCD display, and a Chinese interface. Users enjoy the convenience of freely setting temperatures, while real-time monitoring of furnace temperature and vacuum levels is displayed. The system logs combustion times and faults automatically, enabling seamless operation without the need for manual oversight.
Eliminate the trouble of registration procedures: Simplify your setup with our boiler that arrives fully assembled. Operating under negative pressure, it negates the risk of expansion or explosion and is exempt from governmental supervision and inspection. This feature allows for a hassle-free installation, freeing you from intricate registration processes and minimizing costs.
Energy saving: Discover remarkable energy efficiency with minimal heat medium water requirements. The system's heat exchange occurs in a vacuum chamber filled with negative pressure steam, quickly delivering water at your desired temperature in less than ten minutes, all while minimizing preheating losses and optimizing energy savings.
Long life: Constructed from stainless steel renowned for superior heat transfer and corrosion resistance, our exchangers ensure rapid heat transmission. Flanged pipe connections simplify maintenance, while the vacuum environment prevents corrosion or scaling. The innovative design extends the service life by minimizing direct contact with flames or flue gases.
Insulation structure: Equipped with a 100mm double-layer insulation structure, the external surface temperature of the boiler remains at room temperature. This not only enhances safety but also significantly boosts thermal efficiency, making it an ideal choice for energy-conscious environments.
Imported low-nitrogen burner: Our advanced low-nitrogen burner ensures high-efficiency combustion and operates with minimal noise and emissions. It adheres to the stringent requirements of the nation's first-class areas, providing an environmentally friendly solution.
