Product Description

Product Description

One machine for multiple purposes: Thanks to innovative design and a sophisticated structure, our vacuum boiler boasts dual hot water outputs. This allows it to provide hot water with varied temperature differences simultaneously. Whether you opt for a dual-circuit or single-circuit system, both can operate independently, offering unparalleled flexibility.
High thermal efficiency: Experience superior heat exchange in our completely sealed vacuum chamber. Crafted from imported stainless steel materials, known for their exceptional heat transfer efficiency, our heat exchanger delivers outstanding performance and significant energy savings.
Absolute safety: Operating under a constant negative pressure, our boiler eliminates any explosion risks. It is fortified with an array of safety features including temperature sensors, safety valves, overheat protection, and vacuum control switches, ensuring comprehensive safety from all potential hazards.

Intelligent control: Our advanced digital control system, featuring an intuitive LCD screen with Chinese display, allows for easy and precise temperature adjustments. Real-time display of parameters such as furnace temperature and vacuum degree ensures seamless operation. With automatic recording of combustion times and operational faults, the system enables effortless, unmanned operation.
Eliminate the trouble of registration procedures: Delivered fully assembled and working under a negative pressure, our boiler negates expansion or explosion risks and is free from regulatory supervision. This allows for a streamlined installation process, exempting you from complex registration procedures with functional departments, ultimately reducing your installation costs.

Energy saving: Utilizing minimal heat medium water, our vacuum chamber conducts highly efficient heat exchange with negative pressure steam. This process ensures rapid production of warm water at your desired temperature within just ten minutes, minimizing preheating losses and maximizing energy savings.
Long life: Constructed from top-grade stainless steel, our heat exchanger guarantees swift heat transfer and robust corrosion resistance. Coupled with flange-connected pipe ends for easy maintenance, and operating in a vacuum state to prevent corrosion or scaling, our boiler's lifespan is significantly extended as the heated tube bundle remains unaffected by flame or flue gas.
Insulation structure: Employing a 100mm double-layer insulation structure, our boiler reduces the external touch temperature to ambient levels, enhancing safety while significantly boosting thermal efficiency.
Imported low-nitrogen burner: With high-efficiency combustion and reduced noise, our burner meets national first-class area standards for low exhaust emissions.
