Product Description

Product Description

One machine for multiple purposes: Thanks to its unique design and architecture, our vacuum boiler offers dual hot water outputs, easily delivering water at varied temperature differences simultaneously. It features a versatile dual-circuit system or a standalone single-circuit system tailored to your specific needs with unmatched flexibility.
High thermal efficiency: Our heat exchange system, enclosed in a fully vacuum-sealed chamber, showcases extraordinary thermal efficiency. Engineered from top-grade imported stainless steel, the heat exchanger boasts both exceptional heat transfer capabilities and remarkable energy-saving performance.
Absolute safety: Operating under a continuous negative pressure state, our boiler eliminates explosion risks entirely. Equipped with state-of-the-art safety features like temperature sensors, safety valves, overheat protection, and vacuum control switches, it provides comprehensive protection, ensuring unparalleled operational safety.

Intelligent control: With advanced digital control, an intuitive LCD screen, and a user-friendly Chinese display, our control system is designed for sophistication. Effortlessly set the temperature, view real-time parameters like furnace temperature and vacuum, and benefit from automatic record-keeping of combustion times and operational issues, all without manual oversight.
Eliminate the trouble of registration procedures: Our boiler's innovative negative pressure operation negates any risk of expansion or explosion, exempting it from mandatory supervision and inspection. This allows for seamless installation without cumbersome registration processes, significantly reducing your operational costs.

Energy saving: Utilizing minimal heat medium water, our boiler conducts efficient heat exchange within a negative pressure vacuum chamber. It rapidly produces warm water at your desired temperature in mere minutes, minimizing preheat losses and delivering outstanding energy savings.
Long life: Constructed from premium stainless steel for optimal heat transfer and corrosion resistance, our heat exchanger ensures fast heat transfer. Flange-connected pipe ends allow for easy maintenance and replacement. The vacuum-sealed furnace body prevents corrosion and scale, while the design ensures tubes avoid direct contact with flame or flue gases, significantly extending the boiler's lifespan.
Insulation structure: Our boiler features a 100mm double-layer insulation structure that minimizes external touch temperatures to ambient levels, enhancing safety while significantly boosting the boiler's thermal efficiency.
Imported low-nitrogen burner: This high-efficiency burner ensures optimal combustion, low noise output, and minimal exhaust emissions, meeting the stringent requirements of top-tier environmental standards.
