Product Description

Product Description

One machine for multiple purposes: Our specially designed vacuum boiler elevates versatility to new heights, offering dual hot water outputs with varying temperature differences simultaneously. Whether you choose a dual-circuit or a single-circuit system, enjoy unparalleled flexibility as each operates independently, catering perfectly to your distinct needs.
High thermal efficiency: Experience unparalleled thermal efficiency within a closed vacuum chamber. Crafted from premium imported stainless steel, our heat exchanger ensures exceptional heat transfer efficiency. This advanced design translates into substantial energy savings and superior performance.
Absolute safety: Operate with peace of mind as our boiler maintains a constant negative pressure, eliminating any risk of explosion. Featuring comprehensive safety measures including temperature sensors, safety valves, overheat protection, and vacuum control switches, we've meticulously addressed every potential safety concern.

Intelligent control: Experience cutting-edge digital control with our sophisticated system. A vibrant LCD screen displays all essential parameters like temperature, vacuum degree, and more, in real-time. Effortlessly set temperatures, monitor combustion, and record operational data, all with simplicity and precision, enabling seamless automation.
Eliminate the trouble of registration procedures: Say goodbye to cumbersome registration procedures with our hassle-free boiler. Shipped fully assembled and functioning under negative pressure, it negates any expansion or explosion risk, exempting you from regulatory inspections and significantly cutting down costs.

Energy saving: Our innovative design minimizes heat medium water usage, optimizing energy efficiency. By conducting heat exchange in a negative pressure vacuum chamber, it quickly produces warm water within ten minutes without preheating loss, delivering remarkable energy savings.
Long life: Constructed with top-tier stainless steel, our heat exchanger boasts rapid heat transfer and exceptional corrosion resistance. Flange-connected pipe ends simplify maintenance, while the vacuum state prevents corrosion and scale buildup, prolonging the furnace's lifespan.
Insulation structure: Embracing a 100mm double-layer insulation, our boiler maintains external temperatures at room level, enhancing safety and significantly boosting thermal efficiency. This advanced insulation design ensures optimal performance and energy conservation.
Imported low-nitrogen burner: Enjoy high-efficiency combustion with our imported burner, designed for low noise and reduced emissions, perfectly aligning with national first-class area standards for a cleaner, quieter operation.
