Experience the flexibility of providing two different temperature levels simultaneously with either a dual-circuit system or a versatile single-circuit system, each functioning independently to suit your unique needs.
High thermal efficiency: Revolutionary Heat Exchange Efficiency: Experience unparalleled heat exchange as the heat circulates within a fully sealed vacuum chamber. Crafted from the finest imported stainless steel, this system ensures exceptional heat transfer efficiency, delivering outstanding energy savings while maximizing heat exchange performance.
Absolute safety: Robust Safety Measures Ensured: The boiler consistently operates under a negative pressure state, eliminating any risk of explosion. Equipped with a comprehensive array of safety features—including temperature sensors, safety valves, overheat protection, and vacuum control switches—every potential safety hazard is meticulously addressed to guarantee peace of mind.
Intelligent control: Cutting-Edge Intelligent Control: Featuring a digital control system with an intuitive LCD screen and Chinese display, this advanced system allows for seamless operation. Easily set temperatures while conveniently viewing real-time readings of furnace temperature, vacuum degree, and more. Automated recording of combustion time and operational faults simplifies use, enabling effortless hands-free operation.
Eliminate the trouble of registration procedures: Hassle-Free Operation Unlocked: Delivered as a complete unit and functioning under negative pressure, this boiler eradicates any potential for expansion or explosion, exempting it from stringent supervision and inspection. Simplify your installation process by bypassing cumbersome registration procedures, significantly reducing costs and ensuring efficient setup.
Energy saving: Remarkable Energy Efficiency: Utilizing a minimal amount of heat medium water, this system conducts heat exchange in the vacuum chamber using negative pressure steam. Achieve your desired water temperature within a mere ten minutes, all while minimizing preheating losses. Enjoy substantial energy savings with this highly efficient solution.
Long life: Durable Construction for Longevity: Made from high-quality stainless steel, the heat exchanger boasts rapid heat transfer and exceptional corrosion resistance. Flanged connections at the pipe ends facilitate easy maintenance and replacement. With its vacuum state protecting against corrosion and scale, and the heated tube bundle shielded from flame or flue gas, this design significantly extends the unit's service life.
Insulation structure: Enhanced Efficiency with Insulation: Employing a robust 100mm double-layer insulation structure, this design minimizes external touch temperatures, aligning them with room temperature. This not only amplifies safety but also dramatically enhances the boiler's thermal efficiency, setting a new standard for operational excellence.
