Pressure vessel AQUA OLA 200l with manometer vertical - standing

Product detailed description

Vertical expansion tanks are essential components in water supply systems where pressure stability is required. This model is commonly installed in residential properties, pumping stations, and industrial facilities to maintain consistent pressure and reduce pump cycling. The tank is designed to work with all pump types that do not exceed the maximum working pressure of 6 bar. The EPDM bladder ensures compatibility with potable water systems and minimises the need for additional air management components.

When integrating this tank into a system, the installer must consider the system's pressure requirements and the tank's capacity. The 200L volume is suitable for larger installations where frequent pump starts need to be minimised. The tank's vertical orientation allows for efficient space utilisation in mechanical rooms or utility areas. The tank is supplied with a pre-charged air pressure of 2 bar, which should be verified during installation.

The 200L capacity and 6 bar maximum working pressure are critical for proper system sizing. A larger tank volume reduces the frequency of pump starts, which in turn extends the system's lifespan. The 6 bar limit ensures compatibility with standard domestic and industrial pump systems. The EPDM bladder is suitable for potable water and requires periodic air pressure checks to maintain optimal performance.

Installation and connection

To install the AQUA OLA 200L expansion tank, first ensure the location is accessible for maintenance and has sufficient clearance for the tank's dimensions (112 x 58.5 cm). The tank should be mounted vertically on a stable surface. Connect the tank to the system using appropriate pipe fittings that match the inlet and outlet dimensions. The tank's internal bladder is pre-charged to 2 bar, but this should be verified with a pressure gauge before commissioning. Common installation errors include incorrect orientation (horizontal instead of vertical) and failure to check the initial air pressure. Always ensure the tank is fully drained before maintenance and repressurised to the correct level after installation.

Compatibility and accessories

This expansion tank is compatible with all pump systems that operate within the 6 bar pressure range. It is suitable for use with domestic water supply systems, pressure boosting stations, and industrial water circulation systems. No additional accessories are required for basic installation, but a pressure gauge may be added for monitoring purposes. The tank is not compatible with systems that require higher pressure ratings than 6 bar. Related products include standard and high-pressure expansion tanks from the same manufacturer.

Technical background for designers

The AQUA OLA 200L expansion tank operates on the principle of separating water and air using an EPDM bladder. The bladder expands and contracts in response to pressure changes in the system, maintaining a stable pressure without the need for additional air management. The steel construction provides structural integrity and durability, while the EPDM material ensures compatibility with potable water and resistance to chemical degradation. The tank's vertical orientation allows for efficient use of space in mechanical rooms. The service life of the tank is influenced by the frequency of pressure fluctuations, the quality of the water in the system, and the regularity of air pressure checks. Proper sizing of the tank is essential to prevent excessive pump cycling and to ensure long-term system reliability.

Service and operation

Regular maintenance of the AQUA OLA 200L expansion tank includes checking the internal air pressure every six months. If the pressure drops below the initial 2 bar setting, it should be recharged using a suitable air pump. The tank should be inspected for signs of wear or damage to the bladder and outer shell. During inspection, ensure that the tank is fully drained and that all connections are secure. No other maintenance tasks are required under normal operating conditions. If the tank is not used for an extended period, it should be drained and stored in a dry location to prevent internal corrosion.

Frequently asked questions

Can the AQUA OLA 200L tank be used with a 5 bar pump system?
Yes, the tank is compatible with pump systems that do not exceed the 6 bar maximum working pressure. A 5 bar pump will function within the tank's operating range.

Is the EPDM bladder suitable for hot water applications?
Yes, the EPDM bladder is suitable for potable water and can handle typical domestic water temperatures. However, it is not designed for high-temperature applications beyond standard water supply systems.

Can the tank be installed in a horizontal position?
No, the tank is designed for vertical installation only. Horizontal installation may affect the internal pressure distribution and reduce the tank's efficiency.

How often should the air pressure be checked?
The air pressure in the tank should be checked approximately every six months to ensure it remains at the initial 2 bar setting. This helps maintain optimal performance and extends the tank's service life.
