Vacuum Hot Water Boiler Advantage

1. Safe and reliable: Vaccum hot water boiler adopt phase change working principle. its medium circulation system pressure below the atmospheric pressure, internal absolute pressure is 0.02 ~ 0.08 MPa, so that it can’t explode.

2. High thermal efficiency: adopt three pass structures, the second return pipe is currugated pipe, which increase the heating surface.the third return pipe adopt the light pipe, which effectively reduce the flue gas flow resistance. Thermal efficiency reach 92%.

3. Long service life: because of internal special medium, there is no other medium add during operation. boiler scale do not occur within the boiler. This increase the service life of boiler, General life of vaccum hot water boiler is 2times of normal hot water boilers.Heat exchanger are made of corrosion resistance stainless steel pipe, design service life is more than 20 years.
4. Control accurate: according to load change, vaccum hot water boiler will automatic adjust. Hot water temperature can be set freely between 20 ~90 ℃

5. High qullity component: boiler combustion and control system components adopt imported high quality accessories, such as: Germany weishaupt burner or Italy Baltur, RIELLO burner ;German SEMIENS touch screen, PLC programmable controller.

6. Convenient installation: built-in heat exchanger system do not require external devices such as water treatment and heat exchanger, the cost for installation is reduced greatly.
7. Meet environment protection requirement: the fuel combustion, low carbon;The secondary combustion, effective inhibition of NOX formation;Burning low noise, low back pressure in chamber.
