Pressure expansion vessel - heating and cooling systems - 500l; 10bar; 5/4"; vertical with base. IVAR.ERCE 500 - AQUAHOT

Product detailed description

Pressure expansion vessels are essential components in closed heating and cooling systems, where thermal expansion of the fluid must be accommodated safely. The IVAR A112L55 is designed for use in a range of building types, including residential, commercial and industrial installations. It supports systems operating within a wide temperature range, making it suitable for both traditional and modern heating solutions. Installers working with closed-loop systems, including those with antifreeze mixtures, will find this vessel appropriate for maintaining system pressure and preventing overpressure conditions.

Correct sizing and selection of an expansion vessel are critical to system performance. The vessel must be able to handle the maximum expected expansion volume of the system fluid under normal operating conditions. The 500L capacity of the A112L55 is suitable for larger systems, while the 10bar pressure rating ensures compatibility with high-pressure applications. The 5/4 inch connection is a standard size for such vessels, allowing integration with typical system piping. The operating temperature range of -10°C to +99°C allows for use in both heating and cooling applications, although the recommended operating temperature is up to +80°C.

Brand	IVAR

The technical parameters of the IVAR A112L55 are crucial for proper system integration. The 500L capacity indicates the volume of fluid the vessel can accommodate for expansion, while the 10bar pressure rating ensures it can handle high-pressure environments. The 5/4 inch connection is a standard size for such vessels, and the operating temperature range of -10°C to +99°C allows for use in both heating and cooling systems. The recommended operating temperature of up to +80°C is important for ensuring long-term reliability.

Installation and connection

Installation of the IVAR A112L55 requires careful attention to system layout and connection points. The vessel should be mounted vertically with its base in contact with a stable surface. The 5/4 inch connection must be aligned with the system piping, and all joints should be checked for tightness and correct sealing. Common installation mistakes include incorrect orientation, which can affect the vessel's performance, and improper sealing, which can lead to leaks. It is important to ensure that the vessel is installed in a location that allows for easy access for maintenance and inspection.

Compatibility and accessories

The IVAR A112L55 is compatible with a range of heating and cooling systems, including those with antifreeze mixtures up to 50% concentration. It is designed to work with the IVAR.ER - AQUAHOT model for hanging installations and the IVAR.ERCE - AQUAHOT model for vertical installations with a base. When ordering, it is important to ensure that all necessary accessories, such as mounting brackets and sealing materials, are included to facilitate a secure and leak-free installation.

Technical background for designers

The IVAR A112L55 operates on the principle of separating the system fluid from the compressed air or gas within the vessel using an SBR membrane. This membrane is resistant to the effects of thermal expansion and contraction, ensuring that the vessel can accommodate changes in fluid volume without allowing the fluid to come into direct contact with the air. The SBR material is chosen for its durability and resistance to the effects of antifreeze mixtures. The vessel's integration into the system is critical for maintaining stable pressure and preventing overpressure conditions. Factors that can affect the service life and efficiency of the vessel include the quality of the installation, the operating temperature, and the concentration of antifreeze in the system.

Service and operation

Regular maintenance of the IVAR A112L55 is essential for ensuring long-term performance. This includes checking for leaks, inspecting the membrane for signs of wear, and verifying that the pressure within the vessel remains within the specified range. While the brief does not specify service intervals, it is recommended to perform routine inspections as part of the system's overall maintenance schedule. Any signs of damage or wear should be addressed promptly to prevent system failure.

Frequently asked questions

Can the IVAR A112L55 be used with antifreeze mixtures?
Yes, the vessel is suitable for use with antifreeze mixtures up to a maximum concentration of 50%. This makes it appropriate for systems where freeze protection is required.

Is the IVAR A112L55 suitable for hanging installations?
Yes, the vessel is available in a version for hanging installations (IVAR.ER - AQUAHOT). However, the model described here is a vertical design with a base (IVAR.ERCE - AQUAHOT).

What is the maximum operating temperature for the IVAR A112L55?
The recommended operating temperature is up to +80°C, although the vessel can operate within a wider range of -10°C to +99°C.

Can the IVAR A112L55 be used in cooling systems?
Yes, the vessel is suitable for both heating and cooling systems due to its wide operating temperature range.
