Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Thanks to its innovative design and unique structure, the vacuum boiler boasts dual hot water outputs, allowing it to deliver hot water with varying temperature differences simultaneously. Whether using the dual-circuit system or opting for the single-circuit setup, these systems can function independently, providing versatile usage options.
High thermal efficiency: Within a perfectly sealed vacuum chamber, heat exchange undergoes a continuous cycle. Crafted from premium imported stainless steel, renowned for its superior heat transfer efficiency, the heat exchanger guarantees outstanding heat exchange performance and a remarkable energy-saving impact.
Absolute safety: Operating under a consistent negative pressure state, this boiler eliminates explosion risks. Equipped with an array of protective measures, including temperature sensors, safety valves, overheat protection, and vacuum control switches, every potential safety concern is meticulously addressed for utmost safety.
Intelligent control: With a cutting-edge digital control interface, featuring a user-friendly LCD screen and Chinese display, the system offers unparalleled control. Users enjoy the freedom to set temperatures, monitor real-time parameters like furnace temperature and vacuum degree, and have combustion times and operational faults automatically logged, all with effortless operation and the convenience of remote automation.
Eliminate the trouble of registration procedures: Delivered fully assembled and operating under negative pressure, this boiler is exempt from typical expansion or explosion concerns and thereby not subject to customary supervision and inspection. This streamlined approach eliminates the need for cumbersome registration processes, ensuring cost savings during installation.
Energy saving: Utilizing a minimal amount of heat medium water, the vacuum chamber's negative pressure steam facilitates highly efficient heat exchange. This results in the rapid production of water at the desired temperature in under ten minutes, with virtually no preheating losses. The energy savings achieved are undeniably impressive.
Long life: Constructed of stainless steel for unparalleled heat transfer and resistance to corrosion, the heat exchanger ensures rapid and efficient heat transfer. The flange connections at pipe ends allow for straightforward maintenance and replacement. Operating in a vacuum environment, the boiler body resists corrosion and scaling, while its heat tubes remain untouched by flame or flue gases, significantly extending its lifespan.
Insulation structure: Incorporating a 100mm double-layer insulation design, the boiler's exterior temperature is minimized to match room conditions. This not only enhances safety but also substantially boosts the thermal efficiency of the boiler.
Imported low-nitrogen burner: Experience optimal combustion efficiency with minimal noise and reduced exhaust emissions, ensuring compliance with the stringent standards of first-class areas nationwide.
