Product Description

Product Description

One machine for multiple purposes: Crafted with a unique design and sophisticated structure, our innovative vacuum boiler stands out by delivering dual hot water outputs. It elegantly manages to provide water at varying temperature levels simultaneously, utilizing a dual-circuit system or a single-circuit system, both of which operate independently to seamlessly cater to your distinct needs.
High thermal efficiency: Experience unparalleled energy savings with our vacuum chamber's advanced heat exchange system, which circulates heat efficiently. Constructed from premium imported stainless steel, our heat exchanger provides extraordinary heat transfer capabilities, ensuring outstanding thermal performance and significant energy conservation.
Absolute safety: Operating perpetually under a negative pressure state, our boiler eliminates explosion risks, safeguarding your environment. It is meticulously equipped with an array of safety features including temperature sensors, safety valves, overheat protection, and vacuum control switches, offering comprehensive protection against potential safety hazards.

Intelligent control: Our state-of-the-art digital control system features an intuitive LCD screen with a Chinese interface that allows you to set temperatures freely. Displaying real-time parameters such as furnace temperature and vacuum degree, the system automatically logs combustion times and operational faults, simplifying operations to the extent that no manual supervision is required.
Eliminate the trouble of registration procedures: Arriving fully assembled and operating under negative pressure, our boiler is exempt from expansion or explosion risks, thus bypassing the need for rigorous inspections. Consequently, you can avoid the burdensome registration processes with functional departments, thereby minimizing your costs significantly.

Energy saving: Thanks to its minimal heat medium water and efficient heat exchange within the negative pressure vacuum chamber, our boiler achieves the set water temperature in mere minutes, without any preheating losses. This efficiency translates into substantial energy savings, highlighting its eco-friendly credentials.
Long life: Constructed with the finest stainless steel for optimal heat transfer and corrosion resistance, our heat exchanger promises longevity and top-notch performance. Flange connections facilitate easy maintenance while the vacuum state prevents corrosion or scaling. Without direct flame or flue gas contact, the heated tube bundle enjoys an extended service life.
Insulation structure: Our boiler features a robust 100mm double-layer insulation structure, reducing the external surface temperature to room level. This enhances safety and boosts thermal efficiency, ensuring that your boiler operates at peak performance while maintaining a cool touch exterior.
Imported low-nitrogen burner: Delivering high-efficiency combustion with minimal noise and low emissions, our burner adheres to the stringent environmental standards of first-class areas, leading the way in eco-friendly technology.
