Vacuum Hot Water Boiler (T7)

Vacuum Hot Water Boiler (T7)

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.
