Pressure vessel AQUA OLA 100l, standing

Product detailed description

Vertical expansion tanks are essential components in water supply systems where pressure fluctuations and water storage requirements demand reliable and efficient solutions. This model is commonly used in residential, commercial and industrial settings, particularly in systems where a stable water supply is critical. Installers working with pump stations, pressure boosting systems and domestic water supply networks will find this tank suitable for integration into systems with a maximum operating pressure of 6 bar. The tank is designed to reduce the number of pump start-stop cycles, thereby increasing the overall system lifespan and reducing maintenance requirements.

When selecting an expansion tank, it is important to consider the system's pressure range and the volume of water that needs to be stored. The tank's internal EPDM bladder ensures compatibility with potable water and prevents direct contact between the water and the steel tank body. The tank is pre-charged with air at 2 bar from the factory, which can be adjusted depending on the system requirements. The tank is not suitable for pressures exceeding 6 bar, as this could lead to mechanical failure and bladder rupture over time.

The capacity of 100 litres is suitable for systems with moderate to high water demand, ensuring a buffer that reduces the frequency of pump operation. The dimensions (99 x 46 cm) indicate a vertical orientation, which is ideal for installations with limited horizontal space. The operating pressure range up to 6 bar means the tank can be used with a variety of pump types, provided the system does not exceed this limit. The factory pre-charge of 2 bar is a baseline for initial system setup and should be adjusted based on the specific system pressure requirements.

Installation and connection

Installation of the AQUA OLA 100l tank should be carried out in a location that allows for easy access to the air valve for periodic pressure checks. The tank is connected to the system using standard pipe fittings, and the connection size must be verified to ensure compatibility with the system's piping. The tank should be mounted vertically, with the air valve positioned at the top for accurate pressure adjustment. It is important to ensure that the system pressure does not exceed the tank's maximum operating pressure of 6 bar, as this can lead to premature failure. A common mistake during installation is neglecting to adjust the pre-charge pressure to match the system's operating pressure, which can result in inefficient operation and increased pump cycling.

Compatibility and accessories

The AQUA OLA 100l tank is compatible with a wide range of pump types and pressure control systems, provided the system pressure remains within the specified operating range. It is suitable for use with domestic water supply systems, pressure boosting stations and industrial water handling applications. No additional accessories are required for basic operation, but it is recommended to install a pressure gauge and air valve for monitoring and maintenance purposes. The tank's EPDM bladder ensures compatibility with potable water systems, making it suitable for applications where water quality is a priority.

Technical background for designers

The tank operates on the principle of separating water and air using an internal EPDM bladder. The bladder expands and contracts in response to changes in system pressure, allowing the tank to store and release water as needed. The steel tank body provides structural integrity and resistance to internal pressure. The EPDM material is chosen for its compatibility with potable water and its resistance to degradation from water and common disinfectants. The tank's efficiency is influenced by the accuracy of the pre-charge pressure and the system's overall pressure dynamics. A larger tank volume reduces the frequency of pump operation, which in turn reduces wear and extends the system's service life.

Service and operation

Periodic maintenance is required to ensure the tank operates efficiently. The air pressure inside the tank should be checked every six months and adjusted if necessary to match the system's operating pressure. A drop in pressure can indicate a leak in the bladder or air valve. No other maintenance tasks are required for normal operation. The tank's design minimises the need for complex maintenance procedures, making it a low-maintenance solution for water supply systems.

Frequently asked questions

Can the AQUA OLA 100l tank be used with a system operating at 5 bar?
Yes, the tank is suitable for systems with operating pressures up to 6 bar. A system operating at 5 bar is within the tank's capacity and will function as intended.

What happens if the system pressure exceeds 6 bar?
If the system pressure exceeds 6 bar, the tank may experience mechanical stress that could lead to failure. The internal bladder may stretch beyond its limits, resulting in rupture and system malfunction.

Is the EPDM bladder suitable for potable water?
Yes, the EPDM bladder is specifically designed for use with potable water and is resistant to degradation from water and common disinfectants.

How often should the air pressure be checked?
The air pressure should be checked every six months to ensure it remains at the correct level. A drop in pressure can affect the tank's performance and increase pump cycling.
