Product Description

Product Description

One machine for multiple purposes: Our advanced vacuum boiler is ingeniously engineered to cater to diverse heating needs. Its versatile design allows it to seamlessly provide hot water of varying temperature requirements, adapting effortlessly to any situation. Thanks to its groundbreaking design and architecture, the vacuum boiler boasts dual hot water outputs, delivering water at different temperature differences simultaneously. Whether utilizing a dual-circuit or a single-circuit system, each operates independently, offering unparalleled flexibility.
High thermal efficiency: Our vacuum boiler excels in energy conversion, ensuring maximum heat retention and minimal wastage. Within a completely sealed vacuum chamber, heat exchange is continuously recycled. Constructed from premium imported stainless steel, this ensures exceptional heat transfer efficiency, resulting in significant energy conservation and reduced operational costs.
Absolute safety: Your safety is our priority, with built-in features that proactively mitigate risks. Operating under a constant negative pressure eliminates any explosion hazards. Equipped with temperature sensors, safety valves, advanced overheat protection, and vacuum control switches, our boiler is fortified with comprehensive safety measures, addressing every conceivable risk.

Intelligent control: Revolutionize your heating experience with our sophisticated control system, combining technology and user-friendliness. Harness the power of digital control with an intuitive LCD screen and Chinese interface. Set temperatures with ease, monitor parameters in real-time, and track combustion times and system alerts-all with a touch. Enjoy hassle-free, automated operation.
Eliminate the trouble of registration procedures: Simplify your installation experience, cutting through bureaucratic red tape. Shipping fully assembled and operating under negative pressure, our boiler circumvents the need for extensive regulatory inspections and registrations. Seamlessly installed, it empowers you to save both time and costs.

Energy saving: Maximize energy efficiency and minimize costs with our cutting-edge energy-saving technology. The system's minimal heat medium water ensures rapid heat exchange within a negative pressure vacuum, heating water to your desired temperature in mere minutes without preheating losses. Witness a striking reduction in energy consumption.
Long life: Designed for durability, our boiler promises longevity and sustained performance. Crafted from top-grade stainless steel, the heat exchanger guarantees swift heat conduction and superior corrosion resistance. Vacuum-sealed, it avoids corrosion and scaling, extending the lifespan significantly without exposure to damaging flames or flue gases.
Insulation structure: Experience enhanced safety and efficiency with our superior insulation technology. Our 100mm double-layer insulation structure minimizes external heat loss, maintaining the boiler's surface at room temperature. This not only elevates safety standards but also significantly boosts thermal performance.
Imported low-nitrogen burner: Embrace eco-friendly efficiency with our advanced low-nitrogen burner. Delivering high combustion efficiency with minimal noise and reduced emissions, our burner complies with stringent national requirements for first-class environmental standards.
