Pressure expansion vessel - water supply systems - 100l; 10bar; 1"; vertical with base IVAR.AFV 100 - AQUACOLD

Product detailed description

Pressure expansion vessels are essential components in potable water supply systems where thermal expansion of water must be accommodated. This is particularly relevant in residential and commercial buildings equipped with closed-loop water heating systems. Installers working on such systems must ensure that expansion vessels are correctly sized and positioned to prevent pressure fluctuations and system damage. The IVAR A032L38 is a vertical model designed for integration into these systems, providing reliable performance in a range of environments.

With a working temperature range from -10°C to +99°C, the vessel is suitable for installations where water temperatures may vary significantly. The recommended operating temperature is up to +80°C, making it ideal for domestic hot water systems. The vertical orientation with a base ensures a stable installation, particularly in confined spaces where horizontal models may not be feasible.

Technical parameters

Code	A032L38
Brand	IVAR

The 100L capacity and 10bar pressure rating are critical for determining the vessel's suitability for a given system. These parameters ensure that the vessel can handle the expected volume of thermal expansion without exceeding pressure limits. The 1 inch connection size is standard for many water supply systems and must be matched with the system's piping to ensure compatibility.

Installation and connection

The IVAR A032L38 is installed using a 1 inch connection, typically via a threaded or flanged joint. The vertical orientation requires sufficient clearance for maintenance and inspection. Installers should ensure that the vessel is mounted on a stable base and that all connections are leak-free. Common installation errors include incorrect orientation, failure to secure the base, and improper alignment with the system's pressure relief valve. It is essential to verify that the vessel is installed in accordance with the manufacturer's guidelines and local regulations.

Compatibility and accessories

The vessel is compatible with standard potable water supply systems and can be integrated with pressure relief valves and temperature sensors. Additional components such as mounting brackets or insulation may be required depending on the installation environment. Related models include the IVAR.AC (hanging), IVAR.AFH (horizontal with legs), and IVAR.AFV (vertical with base), which offer alternative mounting options for different system layouts.

Technical background for designers

The vessel operates on the principle of separating the expanding water from the system using a replaceable EPDM membrane. This membrane ensures that the vessel can accommodate thermal expansion without allowing water to enter the air chamber. The EPDM material is resistant to a wide range of temperatures and is suitable for potable water applications. The vessel's integration into the system depends on the system's pressure and temperature dynamics, and designers must account for these factors when selecting the appropriate model. The vessel's service life is influenced by the quality of the membrane and the operating conditions, including exposure to UV light and chemical contaminants.

Service and operation

Routine maintenance includes checking for leaks, inspecting the membrane for signs of wear, and verifying the pressure within the vessel. The replaceable membrane allows for easy servicing without the need to replace the entire unit. Installers should refer to the manufacturer's guidelines for recommended service intervals and procedures. During operation, the vessel should be monitored for any changes in pressure or performance that may indicate a need for maintenance.

Frequently asked questions

Can the IVAR A032L38 be used in systems with higher pressure than 10bar?
No, the vessel is rated for a maximum pressure of 10bar and should not be used in systems exceeding this limit.

Is the EPDM membrane compatible with all types of potable water?
Yes, the EPDM membrane is suitable for potable water applications and is resistant to a wide range of temperatures and chemical conditions.

Can the vessel be installed in a horizontal position?
No, the IVAR A032L38 is specifically designed for vertical installation with a base and should not be used in a horizontal orientation.

What is the recommended operating temperature range?
The recommended operating temperature is up to +80°C, although the vessel can function in environments with temperatures ranging from -10°C to +99°C.
