## Summary description

Open horizontal expansion vessel by Kaps with 10-liter capacity for heating (CO) systems. Designed to accommodate thermal expansion in closed-loop central heating circuits, this open-type horizontal tank helps maintain pressure balance and protect components from overpressure.

## Long description

Open horizontal expansion vessel Kaps 10 L is designed for heating (central heating/CO) systems to accommodate thermal expansion in closed-loop circuits. With a 10-litre capacity and horizontal orientation, this open-type tank helps maintain pressure balance, reduce stress on pipes and components, and provide a compact solution for residential and small commercial installations where space constraints or plumbing layout favour a horizontal vessel.
Advantages
The horizontal open design allows straightforward venting and connection in low-height installations while providing reliable accommodation of thermal expansion in heating circuits. The compact 10 L volume is suitable for smaller systems and helps limit heat losses compared with larger tanks. Constructed for use in central heating systems, the vessel contributes to maintaining hydraulic stability and protecting pumps, valves and radiators from excess pressure variations.
Suitable for
 Residential central heating systems with limited space
 Small commercial heating circuits
 Retrofit installations that require a horizontal tank configuration
 Systems where open-type expansion vessels are specified for venting and maintenance access
Key specifications
