Thermal power: 1-20 t/h
Thermal efficiency: >105%
Introduction:Vacuum hot water boiler is an ideal solution for heating supply. Gas is available to be used in the heating boiler. There is completely deoxy purified water in the furnace, so there is no corrosion and incrustation. Working in the negative pressure, vacuum hot water boiler has none explosion in record.Chat Online Messages Email
Boilers are high temperature resistant, and can be used in areas with high environmental difficulties such as high cold and high altitude.
Intelligent PLC automatic control system, high-color touch screen, with dynamic graphic display, multi-level pop-up menu, automatic fault recording and other operating modes, simple and clear.
Boiler installation design, in-plant commissioning, user site can be used only by installing water and electricity.
|Item||Fangkuai super-cooling vacuum boiler||Normal vacuum boiler|
|Heat exchanger structure||Straight tube could be washed easily from doors of the ends of water room; no damage to heat exchanger||U-type tube is hard to wash; huge damage to heat exchanger|
|Heat transfer technique||Special material plus special structure design make heat transfer area 5 times bigger; high efficiency||Normal material and structure leads higher smoke temperature; low efficiency|
|Test method||Helium Mass SpectrometerLeakDetector; Less than 3×10-8m³pa/s||Water leak detection; About 1.3~5.4×10-4 m³pa/s|
|Safety device||Mechanical safety device; Explosion-proof valve;
|Electrical control device; Solenoid valve; Unstable operation|
|High efficiency condenser||Made of silicon-aluminum alloy; Not easy to scale and easy to clean; Long service life||Traditional fin tube; Easy scaling but not easy to clean; Short service life|
|Packaging appearance||Square structure; Movable door; Easy removal;||Lack of movable door; Hard removal;|
