Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: With its uniquely innovative design and structure, this vacuum boiler offers the incredible ability to deliver dual hot water outputs. Whether through a dual-circuit system or a single-circuit system, this machine can independently provide hot water with varied temperature differences simultaneously, enhancing versatility and functionality.
High thermal efficiency: This boiler's heat exchange process is ingeniously circulated within an entirely sealed vacuum chamber, crafted from top-quality imported stainless steel. Boasting exceptional heat transfer efficiency, the heat exchanger promises outstanding energy conservation and a powerful heat exchange performance that marks a significant leap in energy-saving technology.
Absolute safety: By operating consistently under a negative pressure state, this boiler eliminates the risks associated with explosions. Equipped with an array of safety features including temperature sensors, safety valves, overheat protection, and vacuum control switches, it comprehensively addresses all potential safety concerns, ensuring peace of mind and reliable performance.
Intelligent control: The boiler is equipped with a state-of-the-art digital control system, featuring an LCD screen with Chinese display. This advanced control system allows free temperature setting, with real-time display of furnace temperature, vacuum degree, and other crucial parameters. Additionally, it automatically records combustion time and operational faults. The operation is straightforward, enabling worry-free operation and minimal human intervention.
Eliminate the trouble of registration procedures: Operating under negative pressure, this boiler is delivered fully assembled and inherently safe from expansion or explosion risks. Consequently, it is not subjected to supervision and inspection. During installation, you benefit from exemption from the burdensome registration procedures of functional departments, significantly lowering your costs and simplifying the process.
Energy saving: With minimal heat medium water, the heat exchange occurs efficiently in the vacuum chamber using negative pressure steam. This design achieves rapid warm water production at the desired temperature within ten minutes, eliminating preheating losses and delivering impressive energy-saving results.
Long life: Crafted from stainless steel for optimal heat transfer, the heat exchanger offers swift heat conduction and resistance to corrosion. The pipe ends are conveniently connected with flanges for easy maintenance and replacement. Operating in a vacuum state, the furnace body resists corrosion and scale, while the heated tube bundle remains untouched by flame or flue gas, substantially extending its service life.
Insulation structure: Featuring a robust 100mm double-layer insulation structure, this design minimizes the external touch temperature of the boiler to room temperature. This not only enhances safety but also significantly boosts the boiler's thermal efficiency, providing an impressive balance of security and performance.
Imported low-nitrogen burner: Equipped with a high-efficiency burner, this boiler delivers remarkable combustion with minimal noise and low exhaust emissions, meeting the stringent requirements of the nation's first-class areas.
