Product Description

Product Description

One machine for multiple purposes: Thanks to its innovative design and structure, the vacuum boiler boasts dual hot water outputs, enabling simultaneous delivery of water at varying temperatures. This flexibility is achieved through a dual-circuit system or a single-circuit option, providing versatility and independence in operation.
High thermal efficiency: With heat exchange occurring within a fully enclosed vacuum chamber, crafted from superior imported stainless steel, the boiler exhibits unparalleled heat transfer efficiency. This results in outstanding energy conservation and a significant boost in heat exchange performance.
Absolute safety: Operating under constant negative pressure, the boiler eliminates explosion risks. It features a comprehensive safety suite, including temperature sensors, safety valves, overheat protection, and vacuum control switches, addressing every potential safety concern with diligence.

Intelligent control: Offering cutting-edge digital control via an LCD display with Chinese interface, the system provides real-time visibility of parameters such as temperature, vacuum degree, and more. It autonomously records combustion times and operational anomalies, ensuring ease of use and enabling unattended operation.
Eliminate the trouble of registration procedures: Delivered fully assembled and operating under negative pressure, this boiler circumvents the risk of expansion or explosion, thus exempting it from routine supervision and inspection. Installation is streamlined, bypassing cumbersome registration processes and minimizing operational costs.

Energy saving: Optimal heat exchange in the vacuum chamber, powered by minimal heat medium water and negative pressure steam, achieves high efficiency, producing warm water swiftly within ten minutes without any preheating losses, ensuring impressive energy conservation.
Long life: Constructed with premium stainless steel for unmatched heat transfer and corrosion resistance, the heat exchanger is designed for easy maintenance with flange connections at the pipe ends. The vacuum-sealed furnace body is free from corrosion or scaling, significantly prolonging its service life by protecting the heated tubes from direct flame or flue gas contact.
Insulation structure: Featuring a robust 100mm double-layer insulation, the boiler maintains an external temperature equivalent to room temperature, enhancing safety and substantially elevating its thermal efficiency.
Imported low-nitrogen burner: Engineered for high-efficiency combustion with minimal noise and reduced exhaust emissions, this burner meets the stringent environmental standards of the nation's most regulated areas.
