Product Description

Product Description

One Machine for Multiple Purposes: Thanks to its innovative design and unique structure, our vacuum boiler stands out by delivering dual hot water outputs. It effortlessly supplies hot water at different temperature variations simultaneously through a versatile dual-circuit or single-circuit system, which can function independently. This cutting-edge system ensures maximum flexibility and utility.
High Thermal Efficiency: Experience superior heat exchange within a fully enclosed vacuum chamber. Crafted from premium imported stainless steel, our heat exchanger boasts unprecedented heat transfer efficiency. This results in exceptional energy savings, making it not only effective but also environmentally conscious.
Absolute Safety: Safety is our top priority. Operating under a constant negative pressure, our boiler eradicates explosion risks. Complemented by temperature sensors, safety valves, overheat protection, and vacuum control switches, the multi-layered safety systems comprehensively address all potential hazards. Rest assured of unparalleled peace of mind.

Intelligent Control: Elevate your experience with our state-of-the-art digital control featuring an intuitive LCD screen and Chinese display. With advanced technology, effortlessly set your desired temperature while viewing real-time parameters such as furnace temperature and vacuum levels. The system also logs combustion times and operating faults, ensuring a smooth, user-friendly, hands-off operation.
Eliminate Registration Procedure Hassles: Our boiler arrives fully assembled, operating under negative pressure. This design eliminates expansion or explosion risks, freeing you from the burden of regulatory supervision and inspection. Simplify your installation process as you bypass cumbersome registration processes, significantly reducing associated costs.

Energy Saving: Experience remarkable energy efficiency, thanks to the minimal heat medium water requirement. Heat exchange occurs within the negative pressure vacuum chamber swiftly, heating water to your set temperature in less than ten minutes without preheating loss. Revel in significant energy savings.
Long Life: Built for durability, our heat exchanger utilizes top-grade stainless steel known for excellent heat transfer and corrosion resistance. The flanged pipe connections facilitate easy maintenance and replacement. Operating in a vacuum state prevents corrosion or scaling, and the separation of the tube bundle from flame or flue gas considerably extends service life.
Insulation Structure: Featuring a robust 100mm double-layer insulation structure, our design minimizes external surface temperature to room levels, augmenting safety while significantly enhancing thermal efficiency.
Imported Low-Nitrogen Burner: Our advanced burner achieves high-efficiency combustion with low noise and minimal exhaust emissions, adhering to the stringent standards of premier national areas.
