Product Description

Product Description

One machine for multiple purposes: Ingeniously designed, the vacuum boiler boasts dual hot water outputs, elegantly providing simultaneous hot water with varying temperatures. Its advanced dual-circuit or single-circuit systems operate independently for unmatched versatility.
High thermal efficiency: Experience top-tier thermal efficiency with our vacuum chamber's intricate heat exchange. Crafted from premium imported stainless steel, the heat exchanger offers remarkable energy savings and outstanding heat transfer capabilities.
Absolute safety: Operating under a consistent negative pressure, our boiler eradicates explosion risks. Engineered with temperature sensors, safety valves, and comprehensive overheat protections, we ensure an exceptional safety net, covering all possible hazards.

Intelligent control: Harness advanced digital control through a sophisticated LCD interface with user-friendly Chinese display. Freely adjust the temperature as real-time data on furnace temperature, vacuum levels, and more are displayed. Automated logs of combustion times and faults ensure seamless operations, demanding no manual oversight.
Eliminate the trouble of registration procedures: Shipped fully assembled and operating under negative pressure, our boiler circumvents expansion or explosion risks, thus exempting it from regulatory inspections. Simplifying installation and bypassing tedious registration, this model cuts costs significantly.

Energy saving: With minimal heat medium water, and efficient heat exchange in a vacuum chamber, enjoy quick, warm water production at set temperatures in just ten minutes. Our energy-saving design minimizes preheating losses and maximizes efficiency.
Long life: Made from superior stainless steel, our heat exchanger ensures rapid heat transfer and outstanding corrosion resistance. Flanged pipe ends allow effortless maintenance, while the vacuum state of the furnace body prevents corrosion and scale build-up, significantly prolonging service life.
Insulation structure: Featuring a robust 100mm double-layer insulation, this structure keeps the boiler's touch temperature at ambient levels, enhancing safety while dramatically boosting thermal efficiency.
Imported low-nitrogen burner: Our burner offers efficient combustion with minimal noise and low emissions, perfectly aligning with national first-class area standards.
