Product Description

Product Description

One machine for multiple purposes: With its innovative design and unique structure, the vacuum boiler offers dual hot water outputs, delivering two streams of water at different temperatures simultaneously. This is achieved through either a dual-circuit system or a single-circuit system, both of which can function independently, ensuring versatility and adaptability to your specific needs.
High thermal efficiency: Experience unmatched efficiency where heat exchange occurs in a completely sealed vacuum chamber. Constructed from premium imported stainless steel, this boiler exhibits exceptional heat transfer efficiency, leading to unparalleled energy savings while guaranteeing a high rate of heat exchange.
Absolute safety: Operating under a constant negative pressure state, this boiler eliminates any explosion risks. Equipped with state-of-the-art safety features, including temperature sensors, safety valves, overheat protection, and vacuum control switches, it offers a multi-layered safety framework that addresses every conceivable safety concern.

Intelligent control: Featuring a digital control system and an LCD display with Chinese language support, this advanced control setup allows for precise temperature settings. The screen provides real-time monitoring of furnace temperature, vacuum levels, and more. Automated logging of combustion times and operational faults simplifies the user experience, enabling seamless no-touch operation.
Eliminate the trouble of registration procedures: Delivered fully assembled, this boiler operates under negative pressure and presents no risk of expansion or explosion. This design exempts it from stringent supervision and inspection, thereby eliminating the hassle of conforming to complicated registration procedures, ultimately minimizing your overall costs.

Energy saving: Thanks to minimal heat medium water, efficient heat exchange occurs in the vacuum chamber using negative pressure steam. This innovative process swiftly generates warm water at the desired temperature within ten minutes, eradicating preheating losses and emphasizing significant energy conservation.
Long life: Crafted from stainless steel known for its excellent heat transfer and corrosion resistance, the heat exchanger ensures rapid heat transfer. Flanged connections at pipe ends facilitate easy maintenance and replacement. Being in a vacuum state, the furnace body resists corrosion and scaling, while the heat tube bundle remains untouched by flames or flue gases, significantly extending its operational life.
Insulation structure: Incorporating a 100mm double-layer insulation system, this design reduces the boiler's external touch temperature to ambient room levels. This not only enhances safety but also significantly boosts the boiler's thermal efficiency.
Imported low-nitrogen burner: Delivering high-efficiency combustion with minimal noise, this burner emits low exhaust emissions, perfectly aligning with the stringent requirements of the top-tier environmental standards.
