## Long description

Kaps C413501040 is a 40-liter open horizontal expansion vessel designed for central heating (CO) systems. Made for horizontal installation, this open-type tank receives excess heating water during thermal expansion, helps prevent pressure surges and air locks, and contributes to stable operation of residential and light-commercial heating circuits where open expansion vessels are specified.
Advantages
The vessel provides a compact horizontal layout that simplifies placement in boiler rooms and tight spaces. Its 40 l capacity matches typical small to medium heating circuits, offering sufficient buffer volume to reduce water hammer and limit pressure variation. As an open expansion tank, it supports gravity or low-pressure systems and enables visible free-surface operation, which can simplify maintenance and inspection.
Suitable for
Residential central heating systems with open expansion requirements
Light-commercial heating circuits and small boiler rooms
Gravity-fed or low-pressure heating installations
Systems where horizontal mounting is preferred due to space constraints
Key specifications
Volume: 40 liters
Orientation: horizontal
Type: open expansion vessel for central heating
Application: designed for heating water thermal expansion and pressure stabilization
Installation environment: indoor boiler rooms and heating circuit locations
How to use
Install the expansion vessel in a horizontal position according to the system design and local installation rules. Connect the vessel to the heating circuit at the appropriate expansion point so the tank can accept expanded water from the system. Ensure the tank is mounted securely on a stable support and that pipework connections are properly sealed. Regularly inspect the open vessel for correct water level, signs of corrosion, blockage in vents, or sediment accumulation, and follow local regulations for open-vented systems, including provision of an appropriate feed and overflow arrangement.
Usage recommendations
For reliable operation, match the 40 l capacity to the total water volume and expected temperature range of the heating circuit, and position the vessel where it is accessible for inspection and maintenance. Ensure compliance with local codes for open expansion tanks, keep the vent and feed lines free from obstructions, and check the installation periodically for leaks or corrosion.
