Expansion Vessel Kaps C413503035 – Horizontal Open 35 L with Handles for Heating (35 l)

The Kaps Expansion Vessel C413503035 is a horizontal open-type 35-liter vessel designed for heating systems that require an open expansion container. Constructed for installation in residential and light-commercial boiler setups, this model provides a fluid reserve and accommodates volume changes caused by temperature variations. The horizontal orientation and integrated handles simplify positioning and handling during installation, making it suitable for systems where an open expansion vessel is specified.

Advantages

This expansion vessel offers a compact 35 l capacity that balances space efficiency with adequate reserve volume for small to medium heating circuits. The horizontal design allows for low-profile mounting, while the built-in handles facilitate transport and precise placement. Being an open-type vessel, it is compatible with installations that require an atmospheric connection and straightforward maintenance. The product’s construction supports reliable accommodation of thermal expansion and helps maintain system hydraulic stability.

Suitable for

• Residential central heating systems requiring an open expansion container
• Light-commercial boiler installations with moderate fluid volume changes
• Systems where horizontal mounting or limited vertical space is needed
• Applications that benefit from easier handling during installation and servicing

Key specifications

• Type: Horizontal open expansion vessel
• Capacity: 35 liters
• Orientation: Horizontal with integrated handles for handling and positioning
• Application: Heating systems (open-loop or installations requiring atmospheric expansion)
• Suitable installations: Residential and light-commercial boiler systems

How to use

Mount the vessel on a stable surface or bracket that supports horizontal orientation and allows access to the handles for positioning. Connect the vessel to the heating system at the designated expansion point, ensuring the open top or atmospheric connection is installed as required by system design and local regulations. Fill and commission the system according to the boiler manufacturer’s instructions and observe safe filling and venting procedures. Regularly inspect the vessel and surrounding connections for leaks, corrosion, or blockages that could impair performance.

Usage recommendations

Install this horizontal open expansion vessel in systems specified for open-type expansion, follow local codes for atmospheric connections, and ensure routine inspections. Use the integrated handles to assist safe handling during installation and maintenance; do not use handles as the sole support for long-term mounting. For best results, pair installation with correct system venting and correct placement relative to the boiler and piping layout.
