Product Description

Product Description

One machine for multiple purposes: Ingenious Design Excellence: Thanks to its unique design and structure, our vacuum boiler boasts dual hot water outputs, functioning seamlessly with either a dual-circuit or a single-circuit system. This allows for simultaneous provision of dual hot water streams with varying temperature differences, catering to a spectrum of user needs independently.
High thermal efficiency: Unrivaled Thermal Performance: Within a perfectly sealed vacuum chamber, the heat exchange process is meticulously conducted back and forth. Crafted from premium imported stainless steel materials, our heat exchangers excel in heat transfer efficiency, delivering outstanding energy savings and unparalleled heat exchange effectiveness.
Absolute safety: Uncompromised Safety Assurance: Operating under a consistent negative pressure state, our boiler mitigates any explosion risks. It is fortified with temperature sensors, safety valves, overheat protection, and vacuum control switches, all designed to preemptively address potential safety hazards with robust multi-layer protection.

Intelligent control: Advanced Control Systems: Featuring a sophisticated digital control interface with an LCD screen and Chinese display, our control system is at the forefront of technological advancement. Users enjoy the freedom to set temperatures, while real-time displays of furnace temperature, vacuum degree, and other parameters ensure seamless operation. Automatic recording of combustion time and operating faults enhances user experience, enabling efficient operation without continuous oversight.
Eliminate the trouble of registration procedures: Streamlined Installation Process: Designed to operate under negative pressure, our boiler eliminates the possibility of expansion or explosion, exempting it from stringent supervision and inspection. This simplifies the installation process, bypassing the tedious registration procedures typically required by regulatory departments, thereby minimizing costs significantly.

Energy saving: Remarkable Energy Efficiency: The minimal heat medium water quantity ensures that heat exchange occurs within a vacuum chamber using negative pressure steam, achieving optimal efficiency. This results in warm water production at the desired temperature in under ten minutes, with no preheating loss, offering a substantial energy-saving advantage.
Long life: Durable and Resilient Design: With heat exchangers crafted from superior stainless steel for optimal heat transfer and corrosion resistance, our boilers boast swift heat transfer capabilities. Flange connections at pipe ends facilitate easy maintenance. In a vacuum state, the boiler body is immune to corrosion and scaling, ensuring the heated tube bundle remains untouched by flame or flue gas, thus significantly extending the boiler's service life.
Insulation structure: Enhanced Thermal Insulation: Featuring a 100mm double-layer insulation structure, our boiler minimizes external surface temperatures to align with ambient room levels. This not only elevates safety standards but also substantially boosts the boiler's thermal efficiency.
Imported low-nitrogen burner: Eco-friendly Combustion Technology: Our imported low-nitrogen burner excels in efficient combustion with minimal noise and exceptionally low exhaust emissions, meeting the stringent environmental standards of first-class areas nationwide.
