Kaps CO Vessel Open Horizontal with Handles 30 Litre

Kaps CO Vessel Open Horizontal with Handles 30 Litre is a compact, non-pressurised open expansion and buffer vessel designed for central heating and hot-water systems. The horizontal steel container provides 30 litres of capacity and integrated side handles to assist with manual positioning and installation. The unit is intended to accommodate thermal expansion or to act as a small buffer for system fluid in installations where an open vessel is required.

Advantages

The horizontal design and integrated handles simplify handling and placement in confined plant rooms or boiler cupboards. Being non-pressurised and open to atmosphere, the vessel provides reliable expansion space without the need for additional pressurised expansion components. Its compact footprint suits installations with limited vertical clearance, and the steel construction offers durable containment of heating or hot-water system fluid when installed according to standard plumbing practice.

Suitable for

• Small to medium central heating systems requiring open expansion capacity
• Hot-water systems that need a buffer or expansion vessel open to atmosphere
• Plant rooms or service cupboards with limited vertical space
• Retrofit projects where a compact horizontal vessel is preferred

Key specifications

• Capacity: 30 litres
• Orientation: Horizontal
• Construction: Non-pressurised, open vessel made of steel
• Handles: Integrated side handles for manual handling
• Application: Designed for central heating and hot-water systems

How to use

Install the Kaps CO Vessel Open Horizontal with Handles 30 Litre in a location that remains open to atmosphere and provides safe access for filling, inspection and maintenance. Connect the vessel to the system's expansion or buffer circuit using appropriate piping and fittings, ensuring connections are leak-tight and supported. The vessel must be mounted and levelled on a stable surface; use the integrated handles for manual positioning during installation but secure the unit in place with appropriate brackets or supports if required by the installation. Do not operate the vessel under pressurised conditions; it is intended only for open systems.

Usage recommendations

Follow local regulations and industry standards for open expansion vessels and hot-water system installations. Ensure safe placement to prevent contamination and provide frost protection if installed in unheated spaces. Regularly inspect connections and the vessel for corrosion or leaks and perform maintenance as part of routine system checks.
