Vacuum hot water boiler is absolutely safe and is praised as the
boiler without explosion forever because it operates in the
negative pressure. During the operation process of the boiler, the
hot media (water in boiler) doesnt make any change; it only stays
in the vacuum chamber and transfers heat between heat-exchanging
tube and heat exchanger. The hot media in the furnace is completely
deoxy purified water, so there is no corrosion and incrustation
which makes boilers useful life can reach up to twenty years or
even longer. Besides, it has easy installation, convenient
maintenance and other features which meet the environmental
requirements.
Vacuum hot water boiler is widely used for supplying water for
central air conditioning, sanitary hot water, hot water processing
etc.
The pressure of the medium circulation system is lower than the
atmospheric pressure and the inner absolute pressures from 0.*2 to
0.*8MPa when the boiler in the operation condition, which keep the
unit in the vacuum status, so that the boiler running safely
without explosion.
There is no incrustation inside the boiler to increase boilers
service life which is 1.5 to 2 times than ordinary boilers. The
heat exchanger is made of stainless steel tube which is corrosion
resistant with the lifetime more than *0 years.
Such series boiler adopts three pass structure and wet back
reversal chamber structure. Besides, it uses high-quality aluminum
silicate to preserve heat to make the heat loss of the machine fall
down to limit value and the overall thermal efficiency up to
*2%.
One boiler can be equipped with several heat exchangers for
supplying hot water with different temperature and different
application. For example, the water for central air conditioning,
sanitary hot water, hot water processing etc.
