Pre-Assembled Low Nox Gas Vacuum Boiler No Registration Required

Product Description

Product Description

One machine for multiple purposes: Due to the special design and structure, the vacuum boiler has dual hot water outputs and can provide dual hot water with different temperature differences at the same time, using a dual-circuit system or a single-circuit system that can be used independently of each other.
High thermal efficiency: The heat exchange is circulated back and forth in a completely closed vacuum chamber. Because it is made of imported stainless steel materials with extremely high heat transfer efficiency, The heat exchanger has high heat exchange efficiency and significant energy saving effect.
Absolute safety: The boiler is always in a negative pressure state during operation, and there is no risk of explosion. It is equipped with temperature sensors, safety valves, overheat protection and vacuum control switches and other multi-layer protection measures to take all aspects of potential safety hazards into consideration. 

Intelligent control: digital control, LCD screen, Chinese display, the control system is increasingly advanced, the temperature can be set freely, the furnace temperature, vacuum degree and other parameters are displayed on the screen in real time, the combustion time and operating faults are automatically recorded, the operation is simple, and it can be realized No one is operating.
Eliminate the trouble of registration procedures: The boiler is shipped complete and operates under negative pressure. There is no possibility of expansion or explosion and it is not subject to supervision and inspection. During installation, you can be exempted from the complicated registration procedures of the functional departments, thus reducing your costs as much as possible.

Energy saving: Due to the small amount of heat medium water, heat exchange is carried out in the vacuum chamber with negative pressure steam, which is highly efficient and produces warm water of the set temperature within ten minutes without preheating loss, and the energy-saving effect is significant.
Long life: The heat exchanger is made of stainless steel with the best heat transfer effect, which has fast heat transfer and corrosion resistance; the pipe ends are connected with flanges for easy maintenance and replacement.The furnace body is in a vacuum state, and there is no corrosion or scale. The heated tube bundle does not come into contact with the flame or flue gas, and relatively extends the service life.
Insulation structure: The 100mm double-layer insulation structure is adopted to reduce the external touch temperature of the boiler to room temperature, which not only increases safety but also greatly improves the thermal efficiency of the boiler.
Imported low-nitrogen burner: high-efficiency combustion, low noise, low exhaust emissions, in line with the requirements of the first-class areas of the country.
