These AQUASYSTEM expansion tanks are suitable for closed heating and air conditioning systems, offering the ability to replace the membrane and featuring a repair flange. The most important feature is the interchangeable EPDM membrane, offering replacement and maintenance capabilities, achieving the longest lifespan. The use of these membranes avoids any closing or clogging issues of the supply port, ensuring full discharge of the tank from the contained fluids. With the same nominal volume and under the same temperature and pressure conditions, the tank with an interchangeable membrane moves a larger volume of water in each operating cycle, achieving greater efficiency and fewer pump interventions.
