Product Description
Gas Vacuum Hot Water Boiler
One machine for multiple purposes: Our ingeniously designed vacuum boiler offers versatile functionality with its dual hot water outputs. This advanced system delivers hot water with varying temperature ranges simultaneously, thanks to its unique dual-circuit or independent single-circuit operation.
High thermal efficiency: Experience exceptional energy efficiency with our heat exchange process, operated in a fully sealed vacuum chamber. Crafted from premium imported stainless steel, our heat exchanger boasts remarkable heat transfer capabilities, ensuring significant energy savings and superior performance.
Absolute safety: Our boiler operates under a consistent negative pressure, eliminating explosion risks. Equipped with state-of-the-art safety features such as temperature sensors, safety valves, overheat protection, and vacuum control switches, it comprehensively addresses all potential safety concerns, ensuring peace of mind.
Intelligent control: Featuring cutting-edge digital controls with an intuitive LCD display in Chinese, our advanced system allows users to freely set temperatures. Real-time monitoring of furnace temperature, vacuum level, and other parameters, along with automatic logging of combustion time and operation issues, simplifies operation. Enjoy the convenience of fully automated operation without manual intervention.
Eliminate the trouble of registration procedures: Designed for maximum convenience, our boiler is shipped fully assembled and operates under negative pressure, eliminating expansion or explosion risks. This design exempts you from burdensome registration procedures, saving time and reducing costs significantly.
Energy saving: Our system's efficient design minimizes heat medium water usage, conducting heat exchange with negative pressure steam within the vacuum chamber. This delivers water at the desired temperature swiftly within ten minutes, without preheating losses, showcasing a profound energy-saving advantage.
Long life: Constructed from top-quality stainless steel, our heat exchanger excels in rapid heat transfer and corrosion resistance. Flanged pipe ends ensure easy maintenance, while the vacuum furnace body prevents corrosion and scaling. The lack of direct contact with flames or flue gases extends the system's lifespan significantly.
Insulation structure: Our boiler features a robust 100mm double-layer insulation, lowering external surface temperatures to room level. This innovative design enhances safety while dramatically boosting the boiler's thermal efficiency, ensuring optimal performance.
Imported low-nitrogen burner: Our imported burner ensures high-efficiency combustion with minimal noise and low emissions, meeting the stringent standards of first-class national areas while promoting environmental sustainability.
