Pressure expansion vessel - water supply systems - 50l; 10bar; 1"; horizontal IVAR.AFH 50 - AQUACOLD

Product detailed description

Pressure expansion vessels are essential components in water supply systems to accommodate thermal expansion and maintain stable pressure. This model is commonly used in residential, commercial, and industrial buildings where potable water systems require expansion management. Installers typically integrate these vessels into systems with fixed pressure vessels, ensuring compliance with EU pressure equipment directives. The vessel is designed for operation in environments ranging from -10°C to +99°C, with a recommended service temperature up to +80°C.

Proper sizing and selection of expansion vessels depend on system volume, temperature range, and pressure conditions. The vessel's 50L capacity is suitable for systems with moderate expansion requirements. The 10bar pressure rating ensures compatibility with standard water supply systems. The horizontal orientation and 1 inch connection facilitate integration into existing piping layouts.

The vessel's dimensions (400 mm diameter and 600 mm height) and 50L capacity are critical for determining its suitability for specific system volumes. The 10bar pressure rating ensures compatibility with standard water supply systems. The 1 inch connection size is a standard for many water supply applications. The EPDM membrane is suitable for potable water systems and provides resistance to a wide temperature range.

Installation and connection

The vessel is installed in the water supply system to absorb thermal expansion and maintain pressure stability. The 1 inch connection requires appropriate fittings and thread types to ensure a secure and leak-free connection. Installers should verify the orientation (horizontal) and ensure the vessel is mounted on a stable surface. Common installation mistakes include incorrect orientation, failure to secure the vessel properly, and neglecting to check the pre-charge pressure before commissioning.

Compatibility and accessories

This vessel is compatible with standard water supply systems and can be integrated with pressure-reducing valves and check valves. Additional accessories such as pressure gauges and isolation valves may be required for monitoring and maintenance. The vessel is designed for use with potable water and is CE marked in accordance with EU pressure equipment directives.

Technical background for designers

The vessel operates by separating the water and air chambers with an EPDM membrane. As water expands due to temperature changes, the membrane moves to accommodate the volume change, maintaining system pressure. The EPDM material is resistant to a wide range of temperatures and is suitable for potable water. The vessel's integration into the system depends on the system's thermal expansion characteristics and the required pressure stability. The vessel's service life and efficiency are influenced by the quality of the membrane, the pre-charge pressure, and the system's operating conditions.

Service and operation

Regular maintenance includes checking the pre-charge pressure and inspecting the vessel for signs of wear or damage. The EPDM membrane is replaceable, allowing for long-term service life. The vessel should be checked for leaks and proper operation during routine system inspections. No specific service intervals are provided in the brief, but periodic checks are recommended to ensure continued performance.

Frequently asked questions

Can this vessel be used in systems with temperatures above +80°C?
