Product Description

Product Description

One machine for multiple purposes: Ingeniously designed with a unique dual-circuit or single-circuit system, our vacuum boiler facilitates dual hot water outputs simultaneously, catering to varying temperature needs. This flexibility allows each system to function independently, offering unprecedented versatility.
High thermal efficiency: Engineered for superior performance, the heat exchange process occurs within a fully sealed, vacuum chamber made from premium imported stainless steel, ensuring exceptional heat transfer efficiency. This results in remarkable energy conservation and superior heat exchange capability.
Absolute safety: With its operation in a constant negative pressure state, our boiler eliminates explosion risks. It comes equipped with an array of safety features including temperature sensors, safety valves, overheat protection, and vacuum control switches, ensuring comprehensive protection against potential hazards.

Intelligent control: Featuring cutting-edge digital control and an intuitive LCD display with Chinese language support, this advanced system enables precise temperature settings. Real-time display of furnace temperature, vacuum degree, and parameter readings simplifies operations, while automatic fault recording ensures seamless operation without the need for constant supervision.
Eliminate the trouble of registration procedures: Pre-assembled for maximum convenience, this boiler's operation under negative pressure ensures it bypasses traditional expansion and explosion risks, freeing you from cumbersome supervision and inspection processes. This translates into significant cost reductions during installation.

Energy saving: Designed for maximum efficiency, the system's minimal heat medium water, combined with negative pressure steam in the vacuum chamber, enables rapid heat exchange. It delivers water at the desired temperature efficiently within minutes, drastically cutting preheating losses and enhancing energy savings.
Long life: Built with top-grade stainless steel, the heat exchanger offers rapid heat transfer and robust corrosion resistance. Flange connections at pipe ends simplify maintenance, while the vacuum state of the furnace body prevents corrosion and scaling, significantly extending the service life.
Insulation structure: Our advanced 100mm double-layer insulation system reduces the external boiler temperature to ambient levels, enhancing safety and substantially boosting thermal efficiency.
Imported low-nitrogen burner: Embrace the future with our high-efficiency, low-noise burner that minimizes exhaust emissions, meeting stringent environmental standards of first-class regions in the country.
