Vacuum boiler is consists of combustion chamber, heat transfer tubes, heat medium, vacuum chamber and heat exchanger, etc. The boiler operates under negative pressure, so it is absolute safety. The heat medium is pure water that is completely deoxidized. It only transfers heat in the vacuum chamber, and it has no corrosion and no scale, so the life of the boiler is greatly extended.

Advantage

If you have any questions, you can contact us now.
  • The pressure of the medium circulating system is lower than atmospheric, the boiler operates under negative pressure, no risk of expansion or explosion.
  • There is no scaling inside the boiler and the heat exchanger is made of stainless steel. The design life exceeds 20 years.
  • Vacuum Boiler adopts horizontal type three pass structure. Small in size, easy to install, saves a lot of installation materials.
  • One boiler can be equipped with multiple heat exchangers to supply hot water of different temperatures and different uses.
  • Highly automation. The boiler can automatically control the start and stop and burn time through program settings.
