Product Description

Product Description

One machine for multiple purposes: This ingeniously designed vacuum boiler, with its unique structure, offers dual hot water outputs. It magnificently provides two different temperature variations simultaneously, utilizing either a dual-circuit system or a single-circuit system, each capable of independent operation.
High thermal efficiency: Experience unparalleled thermal efficiency as heat exchange occurs in a fully sealed vacuum chamber. Crafted from imported stainless steel renowned for its superior heat transfer efficiency, the exchanger ensures outstanding heat exchange performance, leading to remarkable energy savings.
Absolute safety: Operating under a constant negative pressure, this boiler eliminates any risk of explosion. Equipped with a spectrum of safety features including temperature sensors, safety valves, overheat protection, and vacuum control switches, it meticulously addresses all potential safety concerns.

Intelligent control: With digital control and an intuitive LCD screen displaying in Chinese, the advanced control system allows for customizable temperature settings. Real-time monitoring of furnace temperature, vacuum degree, and other vital parameters is at your fingertips, with automatic logging of combustion and operational issues, ensuring hassle-free, operator-less functionality.
Eliminate the trouble of registration procedures: Pre-packaged and operating under negative pressure, this boiler negates any chance of expansion or explosion, thus exempting it from oversight and inspection. Installation becomes a breeze as you sidestep cumbersome registration procedures, effectively cutting down on associated costs.

Energy saving: Thanks to the minimal heat medium water required, heat exchange takes place in a vacuum chamber utilizing negative pressure steam, ensuring efficient operation. Within just ten minutes, warm water reaches the set temperature without preheating losses, showcasing significant energy conservation.
Long life: Constructed from premium stainless steel, the heat exchanger boasts exceptional heat transfer and corrosion resistance. Flange-connected pipe ends facilitate maintenance and replacement. In a vacuum state, the furnace body remains free from corrosion or scaling, while its heated tube bundle avoids direct flame or flue gas contact, thereby prolonging its lifespan considerably.
Insulation structure: Employing a 100mm double-layer insulation structure, the boiler minimizes external touch temperature down to room level, enhancing safety and significantly boosting thermal efficiency.
Imported low-nitrogen burner: Designed for high-efficiency combustion with minimal noise and reduced exhaust emissions, this burner meets the stringent standards of top national zones.
