Distribution manifold Afriso KSV 125-5 for heating systems, up to 70 kW, 5 circuits

Afriso KSV 125-5 distribution manifold for heating systems is designed to provide centralized supply and return for up to five heating circuits. Intended for installations with total heating output up to 70 kW, the manifold simplifies the hydraulic layout by grouping pipe connections and enabling separate circuit control. The compact assembly supports clear piping routes and easier commissioning in residential and light-commercial boiler systems.

Advantages

The manifold offers organized distribution of flow and return lines for five circuits within a single unit, reducing installation complexity and saving space in the plant room. It supports hydraulic balancing and uniform heat delivery across circuits, contributing to improved system performance. Constructed for typical heating installations, the unit allows straightforward integration with pumps, valves and temperature sensors, enabling professional-level control and diagnostics.

Suitable for

• Multi-zone residential heating systems with up to five independent circuits
• Small commercial or light-commercial boiler plants requiring separate circuit control
• Renovation projects where centralized distribution and clearer piping are needed
• Heating systems with total output up to 70 kW

Key specifications

• Maximum supported total heating output: up to 70 kW
• Number of circuits: 5 separate supply and return connections
• Function: centralized distribution manifold for supply and return headers
• Compatibility: designed for integration with standard heating pumps, zone valves and temperature sensors
• Installation: wall- or bracket-mounted arrangement for compact plant-room layouts

How to use

Install the Afriso KSV 125-5 manifold according to local regulations and the system design, mounting it securely and aligning supply and return connections with the boiler and circuit piping. Connect each circuit to its dedicated pair of supply and return ports, fit required zone valves or balancing valves, and install pumps and sensors as specified by the hydraulic scheme. Perform hydraulic balancing and check for leaks, then commission the system by gradually bringing it up to operating temperature while monitoring flow and differential pressure.

Usage recommendations

Ensure compatibility with the planned pump sizes and valve types; use appropriate balancing devices and follow manufacturer's installation clearances. Regular inspection of joints and valves and periodic balancing checks will help maintain efficient operation. For installations near the maximum capacity, verify system design calculations to confirm that the manifold and connected components meet the required flow and head conditions.
