Product Description

Product Description

One machine for multiple purposes: Unlock the versatility of our innovative vacuum boiler system, engineered to offer adaptable and multifunctional solutions. With its exceptional design, this vacuum boiler features dual hot water outputs, enabling it to deliver varying temperature hot water simultaneously. Choose between a dual-circuit or a single-circuit system, both operating independently, ensuring flexibility and control for diverse needs.
High thermal efficiency: Harness the power of superior heating with our boiler's remarkable efficiency. The heat exchange process is conducted within a fully enclosed vacuum chamber, utilizing imported stainless steel for outstanding heat transfer efficiency. This results in superior energy savings and a significant reduction in energy consumption, making it a perfect choice for cost-effective operations.
Absolute safety: Our commitment to safety is unwavering, guaranteeing peace of mind during operation. Operating under negative pressure, the boiler eliminates explosion risks and integrates comprehensive safety features such as temperature sensors, safety valves, overheat protection, and vacuum control switches. Every potential hazard is meticulously addressed, ensuring unparalleled safety.

Intelligent control: Seamlessly integrate technology into your heating operations with our advanced control systems. Leverage digital control via an LCD screen with Chinese display, offering highly advanced system management. Freely set your desired temperature, monitor real-time parameters like furnace temperature and vacuum degree, and automatically log combustion times and operational faults. Simplified operation facilitates hands-free management.
Eliminate the trouble of registration procedures: Simplify your setup with our hassle-free, regulation-exempt design. Delivered fully assembled and operating under negative pressure, our boiler negates the risk of expansion or explosion, exempting it from standard oversight and checks. This streamlined installation process cuts down on bureaucratic hurdles and minimizes associated costs effectively.

Energy saving: Optimize your energy consumption with our highly efficient boiler system. Featuring minimal heat medium water and conducting heat exchange under negative pressure steam in a vacuum chamber, it rapidly delivers warm water at the desired temperature within ten minutes, minimizing preheating losses and maximizing energy efficiency.
Long life: Invest in the durability and longevity of your heating solution. Our heat exchanger, crafted from premier stainless steel, ensures excellent heat transfer and resistance to corrosion. With flanged pipe ends for straightforward maintenance, the vacuum furnace body prevents corrosion and scaling, safeguarding the system against flame or flue gas contact and significantly extending its lifespan.
Insulation structure: Redefine efficiency with superior insulation technology. A robust 100mm double-layer insulation structure minimizes external boiler temperature to ambient levels, enhancing safety and significantly boosting thermal efficiency for optimal performance.
Imported low-nitrogen burner: Embrace eco-friendly operation with our high-performance burner. Enjoy high-efficiency combustion with minimal noise and emissions, complying with stringent national standards for first-class areas, ensuring sustainable and quiet operation.
