Product Description

Product Description

One machine for multiple purposes: Our ingeniously designed vacuum boiler offers unparalleled versatility with its dual hot water outputs. Delivering varying temperature differences simultaneously, it features a dual-circuit system or an independent single-circuit system, all thanks to its unique structural innovation.
High thermal efficiency: Experience superior efficiency with our heat exchange system that operates within a fully sealed vacuum chamber. Crafted from premium imported stainless steel, our heat exchanger boasts exceptional thermal efficiency, ensuring significant energy conservation and an impressively high rate of heat transfer for your needs.
Absolute safety: Engineered for unmatched safety, our boiler functions under negative pressure, completely eliminating explosion risks. It comes fully equipped with an array of protective features like temperature sensors, safety valves, overheat protection, and vacuum control switches, addressing every conceivable safety concern comprehensively.

Intelligent control: Advanced digital control is at your fingertips with our intuitive LCD screen featuring a language-friendly Chinese display. Effortlessly customize temperatures while real-time data on furnace temperature, vacuum degree, and more is displayed, facilitating easy, autonomous operation and precise fault monitoring.
Eliminate the trouble of registration procedures: This boiler's complete assembly and negative pressure operation mean you're free from the hassle of extensive registration and inspections. By bypassing these cumbersome procedures, you can focus on cost-efficiency, minimizing expenses while maximizing productivity.

Energy saving: Benefit from remarkable energy efficiency as our vacuum chamber utilizes minimal heat medium water, generating your desired water temperature rapidly within just ten minutes. This eliminates preheating losses and significantly augments the energy-saving credentials of your operation.
Long life: Constructed from the finest stainless steel, our heat exchanger stands out for its exceptional corrosion resistance and rapid heat transfer. Flange connections ensure ease of maintenance and replacement, while the vacuum state guards against corrosion and scale, extending the lifespan of the system considerably.
Insulation structure: Our boiler incorporates a robust 100mm double-layer insulation structure, reducing external surface temperatures to ambient levels. This not only enhances safety but also significantly boosts the thermal efficiency, securing superior performance and energy conservation.
Imported low-nitrogen burner: Delivering efficient combustion with minimal noise and emissions, our low-nitrogen burner complies with stringent first-class environmental standards, ensuring a clean and peaceful operational experience.
