Description
12NA33 Wessels Series NA Hydronic Expansion Tank 23012033, 15 Gal. Wessels NA series are ASME plain carbon steel expansion tanks. They are designed to absorb the expansion forces and control the pressure in heating/cooling systems. This tank is the oldest style that has been used in this system. It works well when the air is controlled and kept in the tank, not in the system. The common face between this air cushion and the water in the tank allows the air to be absorbed by the water.

The expansion tank uses compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. Some tank designs incorporate a diaphragm or bladder to isolate the expanded water from the pressure controlling air cushion, which is pre-charged at the factory and can be adjusted in the field to meet critical system requirements. The design and operation of this style of expansion tank allows the designer engineer to reduce tank sizes up to 80%.
