Product Description

Product Description

One machine for multiple purposes: With its innovative design and sophisticated structure, our vacuum boiler stands out with dual hot water outputs. Imagine having the luxury of dual hot water streams at differing temperatures simultaneously, thanks to its advanced dual-circuit system. Whether you choose to use the dual or single circuit, each functions independently, offering you unmatched versatility.
High thermal efficiency: Experience unparalleled thermal performance with a heat exchange process that's ingeniously looped within a completely sealed vacuum chamber. Crafted from premium imported stainless steel, our heat exchanger boasts extraordinary heat transfer efficiency, delivering not just high thermal performance but also impressive energy savings.
Absolute safety: Engineered for peace of mind, our boiler operates under a constant negative pressure, ensuring zero explosion risk. Enhanced with a suite of protective features including temperature sensors, safety valves, overheat protection, and vacuum control switches, every possible safety concern is meticulously addressed.

Intelligent control: Step into the future with our advanced digital control system. Featuring an intuitive LCD screen with Chinese display, it offers effortless operation with customizable temperature settings. Monitor furnace temperature, vacuum degree, and more, all in real-time. With automatic logging of combustion time and faults, operational simplicity reaches new heights, enabling seamless unattended functioning.
Eliminate the trouble of registration procedures: Simplify your operations with our fully assembled boiler that functions under negative pressure, eliminating any risk of expansion or explosion. Enjoy exemption from tedious registration procedures from regulatory bodies, cutting down installation hassles and optimizing your costs significantly.

Energy saving: Our system's efficient use of minimal heat medium water in a vacuum chamber optimizes heat exchange with negative pressure steam. It produces warm water at your desired temperature in just ten minutes, with no preheating loss, ensuring exceptional energy savings.
Long life: Constructed with high-grade stainless steel, our heat exchanger guarantees rapid heat transfer and resistance to corrosion. Easier maintenance is assured with flange connections at pipe ends. The vacuum-sealed furnace body prevents corrosion and scaling, and with the heated tube bundle isolated from flame and flue gas, the lifespan of your equipment is extended remarkably.
Insulation structure: Our robust 100mm double-layer insulation structure minimizes external boiler surface temperature to room levels. This not only enhances safety but significantly boosts thermal efficiency, maximizing performance.
Imported low-nitrogen burner: Experience optimum combustion efficiency with our imported low-nitrogen burner. It delivers powerful performance with minimal noise and reduced exhaust emissions, meeting the stringent standards of top-tier regions.
