Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Crafted with a unique and innovative design, the vacuum boiler is engineered to perform dual functions effortlessly, providing two streams of hot water with varying temperature differences simultaneously. With the flexibility of a dual-circuit or a standalone single-circuit system, you have the freedom to use each independently, ensuring versatility and efficiency in every application.
High thermal efficiency: The heat exchange system operates within a completely sealed vacuum chamber, allowing for exceptional thermal performance. Constructed with top-grade imported stainless steel, the heat exchanger achieves remarkable heat transfer efficiency, resulting in significant energy savings and outstanding thermal output.
Absolute safety: Operating under consistent negative pressure, the boiler eradicates the risk of explosions. A comprehensive safety suite including temperature sensors, safety valves, overheat protection, and vacuum control switches ensures a fortress of safety, meticulously addressing every potential hazard to provide peace of mind.
Intelligent control: Experience cutting-edge digital control with an LCD display offering a clear Chinese interface. The advanced control system allows for custom temperature settings, real-time monitoring of furnace temperature and vacuum levels, automatic logging of combustion times, and fault detection. This level of automation ensures effortless operation, making manual intervention unnecessary.
Eliminate the trouble of registration procedures: Arriving fully assembled and ready to operate under negative pressure, this boiler negates the risks of expansion or explosion. As a result, it bypasses the need for supervision and inspection, effectively eliminating the cumbersome registration processes and significantly cutting down on your costs.
Energy saving: With minimal heat medium water required, the vacuum chamber's negative pressure steam efficiently conducts heat exchange, reaching the desired water temperature within just ten minutes. This rapid heating eliminates preheating losses and ensures a substantial energy-saving impact, making it a highly efficient solution.
Long life: Designed for longevity, the stainless steel heat exchanger excels in heat transfer and resists corrosion. Easy maintenance is facilitated by flanged pipe connections. Operating in a vacuum state prevents corrosion and scaling, while the tube bundle's isolation from flames or flue gas significantly extends the boiler's lifespan.
Insulation structure: Featuring a robust 100mm double-layer insulation, this structure minimizes external heat loss, keeping the boiler's surface at room temperature. This not only enhances safety but also substantially boosts the boiler's thermal efficiency, ensuring optimal performance.
Imported low-nitrogen burner: Enjoy high-efficiency combustion with minimal noise and emissions. This advanced burner meets stringent environmental standards, aligning perfectly with the regulations of first-class areas, and delivering an eco-friendly heating solution.
