Pressure Maintaining Device with Deaeration and water make-up

Effectively adjust the pressure fluctuation caused by the expansion or contraction of the system water due to temperature change;
Pressure replenishment and pressure relief are carried out inside the equipment, which can effectively prevent the waste caused by the overflow and supplement of the system water.
It can effectively avoid the rapid aging of the equipment caused by the uninterrupted operation of the water pump;
Closed structure to ensure water quality from external pollution;

The diaphragm tank keeps the pressure in the tank consistent with the atmospheric pressure, and uses Henry's law to remove the gas in the water.
No additional manual maintenance is required after installation, and regular routine inspection is required to ensure the normal operation of the equipment.
The pure closed structure completely solves the open system easy to be affected by external factors such as air and installation of high expansion tank problems.
