An expansion tank which contains a bladder is known as a bladder tank. A bladder expansion tank is a system which is used for heating and cooling purposes by absorbing the expansion force. It uses compressed air to adjust with the pressure changes by eliminating or accepting the water volume changes as it expands or contracts due to heating and cooling. A pre-charged bladder tank is an expansion tank which is already charged with air. Bladder expansion tanks offer the benefit of replacing the bladder as and when required.
The bladder separates the expanded water from air. This way, the water does not come into contact with tank and it prevents corrosion by oxygen and rusting. It also increases the pump life by reducing the number of pump cycles. This system prevents water clogging by using an air wall between the interior of the tank and the exterior of the bladder. An Overview of Diaphragm Tanks Diaphragm tanks are water vessels which are subject to a high amount of pressure. These tanks The diaphragm keeps the water and air separate inside the vessel. Diaphragm tanks work in a similar manner as bladder tanks. The key difference lies in the fact that one system uses bladders and the other uses diaphragms. Diaphragms cannot be replaced from a tank. It keeps the system from being waterlogged and prevents absorption of air. This way, it protects water heating and cooling systems. What is the difference between a bladder tank and a diaphragm tank? A bladder tank contains a vinyl tank inside it. A bladder tank can be replaced as and when required. On the other hand, a diaphragm tank contains a rubber flat diaphragm, a butyl tank or a vinyl tank that is mounted on it. The diaphragm is kept attached in the internal area of the tank. Therefore, it cannot be replaced. Both the tanks, bladder and diaphragm, have the same functionality. For more info contact wates pressure vessel supplier in uae or call us at +971 4 252 2966
