Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: With its innovative design and unique structure, the vacuum boiler excels in versatility by offering dual hot water outputs. This advanced machine can simultaneously deliver hot water at varying temperature differences using its sophisticated dual-circuit system or a singular circuit system, each functioning independently to meet diverse needs.
High thermal efficiency: Inside a fully sealed vacuum chamber, the heat exchange process circulates with remarkable efficiency. Crafted from premium imported stainless steel, the heat exchanger boasts exceptional heat transfer capabilities, translating into outstanding energy savings and heightened thermal performance.
Absolute safety: Designed for peace of mind, the boiler operates under a consistent negative pressure, eliminating explosion risks. Equipped with state-of-the-art safety features, including temperature sensors, safety valves, overheat protection, and vacuum control switches, it ensures a comprehensive safeguarding against any potential hazards.
Intelligent control: Embracing cutting-edge technology, the boiler features digital controls with an intuitive LCD screen display in Chinese. The advanced control system allows effortless temperature customization, real-time monitoring of furnace temperature, vacuum levels, and other critical parameters. Automated logs of combustion times and operational diagnostics simplify operations and support unmanned functionality.
Eliminate the trouble of registration procedures: Delivered fully assembled, the boiler operates under negative pressure, negating the risks of expansion or explosion. This design exempts it from regulatory supervision and inspection, sparing you the hassle and cost associated with complex registration procedures, streamlining installation with significant cost reductions.
Energy saving: Featuring minimal heat medium water, the vacuum chamber's negative pressure steam ensures efficient heat exchange, quickly producing hot water at the desired temperature in under ten minutes, without preheating losses. The energy-saving benefits are pronounced, maximizing efficiency.
Long life: Engineered using the finest stainless steel, the heat exchanger delivers rapid heat transfer and robust corrosion resistance. Flange connections at pipe ends facilitate easy maintenance and replacement. The vacuum-sealed furnace body prevents corrosion and scaling, and the heat tube bundle avoids direct exposure to flame or flue gas, significantly prolonging its lifespan.
Insulation structure: Incorporating a 100mm double-layer insulation design, this structure minimizes the external surface temperature of the boiler to ambient levels, enhancing safety and significantly boosting the boiler's thermal efficiency.
Imported low-nitrogen burner: Achieving high-efficiency combustion with minimal noise and low emissions, the burner meets the most stringent national standards for first-class areas, aligning with environmental and regulatory requirements.
