Expansion Tank Reflex NG 35L for Heating and Cooling Systems

The expansion membrane tank of the N, NG series manufactured by Reflex (Germany) has a metal case, divided by a rubber membrane into two chambers: water and air. The air chamber contains air pre-charged under a certain pressure. When the system is heated, expanding water enters the water chamber, and as it cools, it is squeezed back into the system. Water enters and leaves the expansion membrane tank through a threaded connecting pipe.
