The use of hydropneumatic dampers, following a precise analysis of the system and subsequent dimensional determination of the damper, can reduce these pulsations. This means that the utilisation of HYDAC hydraulic dampers brings economic advantages and process reliability. These advantages include: Reduction of pressure pulsations,
In chimney vented residential boilers, both steam and hot water, it is common for manufacturers to include an electrically operated flue damper between the boiler and chimney. By closing the flue pipe between heating cycles, less warm room air was pulled up the chimney through the flue diverter, allowing them to claim a higher efficiency.
