Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Crafted with precision and innovation, our vacuum boiler boasts a unique design and structure that allows it to provide dual hot water outputs simultaneously. Thanks to its versatile dual-circuit or single-circuit system, it serves to deliver distinct temperature differences, operating independently to meet diverse needs with unmatched efficiency.
High thermal efficiency: Designed for superior performance, the heat exchange process transpires within a completely sealed vacuum chamber. Utilizing top-tier imported stainless steel, celebrated for its exceptional heat transfer properties, this heat exchanger achieves remarkable thermal efficiency while offering substantial energy savings.
Absolute safety: Operating perpetually under negative pressure, our boiler is engineered to eliminate any explosion risk. It is fortified with an array of safety features, including temperature sensors, safety valves, overheat protection, and vacuum control switches, all meticulously designed to mitigate any potential hazards.
Intelligent control: Experience the future of boiler management with our state-of-the-art digital control system. The intuitive LCD screen with Chinese display offers real-time insights into parameters such as temperature and vacuum levels. Effortless operation is guaranteed with customizable temperature settings, automated fault recording, and the option for unattended operation.
Eliminate the trouble of registration procedures: Shipped fully functional and operating under negative pressure, our boiler circumvents traditional supervision and inspection requirements. This translates to a streamlined installation process, free from cumbersome registration procedures, significantly cutting down on costs and administrative burdens.
Energy saving: Harnessing the power of highly efficient heat exchange within a negative pressure vacuum chamber, our system delivers water at the desired temperature in mere minutes. This process minimizes preheating losses and maximizes energy savings, underscoring our commitment to sustainability.
Long life: Constructed with stainless steel known for superior heat transfer and corrosion resistance, the heat exchanger promises rapid heat transfer and durability. The vacuum state of the furnace body prevents corrosion and scaling, while flange connections ensure easy maintenance, collectively extending the boiler's operating life.
Insulation structure: Adopting a robust 100mm double-layer insulation structure, our boiler keeps its external touch temperature at ambient levels. This design not only enhances safety but also significantly boosts the boiler's thermal efficiency, optimizing performance.
Imported low-nitrogen burner: Achieve high-efficiency combustion with our imported low-nitrogen burner, designed for minimal noise and reduced exhaust emissions, aligning with the strict regulations of the nation's top-tier areas.
