Product Description

Product Description

One machine for multiple purposes: Thanks to its innovative design and structure, this vacuum boiler excels at versatility. With dual hot water outputs, it can simultaneously deliver hot water at varying temperature differences using either a dual-circuit or single-circuit system, both of which operate independently. This ensures unparalleled adaptability for diverse applications.
High thermal efficiency: Experience superior thermal performance with our advanced heat exchange system, which circulates heat within a fully enclosed vacuum chamber. Crafted from premium imported stainless steel, this heat exchanger boasts exceptional heat transfer efficiency, significantly reducing energy consumption while maximizing savings.
Absolute safety: Prioritizing your safety, our boiler maintains a negative pressure state during operation, eliminating explosion risks. Equipped with comprehensive safety features such as temperature sensors, safety valves, overheat protection, and vacuum control switches, it provides robust, multilayered protection against potential hazards, ensuring peace of mind.

Intelligent control: Embrace cutting-edge technology with our digital control system featuring an LCD screen with Chinese display. Effortlessly set temperatures while monitoring furnace temperature, vacuum degree, and more in real-time. With automatic record-keeping of combustion times and operating faults, the system simplifies operation and supports seamless, unattended functionality.
Eliminate the trouble of registration procedures: Our boiler's complete shipment and negative pressure operation negate the risk of expansion or explosion, exempting it from regulatory supervision and inspection. This means you can bypass cumbersome registration processes, thus dramatically cutting down on costs and administrative burdens.

Energy saving: Leveraging a minimal amount of heat medium water, our boiler conducts efficient heat exchange within a vacuum chamber filled with negative pressure steam. This process swiftly produces warm water at your desired temperature within just ten minutes, eliminating preheating losses and delivering remarkable energy savings.
Long life: Built to last, our heat exchanger utilizes the finest stainless steel for optimal heat transfer, ensuring rapid heat conduction and superior corrosion resistance. With flange-connected pipe ends for easy maintenance, and a vacuum-sealed furnace body free from corrosion or scale, the system prevents contact between the heated tube bundle and flames or flue gas, significantly extending its lifespan.
Insulation structure: Our boiler incorporates a 100mm double-layer insulation structure to maintain external touch temperature at room level, thereby enhancing safety and considerably boosting thermal efficiency.
Imported low-nitrogen burner: Achieve optimal combustion with our imported low-nitrogen burner, delivering high efficiency, reduced noise, and minimal exhaust emissions, compliant with the stringent standards of the nation's most regulated areas.
