## Long description

The Afriso hydraulic separator KSV 125-3 is a compact hydraulic coupling intended for installations with three heating circuits and a heat source capacity up to 70 kW. It provides hydraulic separation between the primary and secondary circuits to stabilize flow and temperature, reduce interaction between circuits, and simplify system commissioning. When combined with appropriate air and dirt separation accessories, the unit also supports removal of entrained air and particulate contaminants to maintain efficient operation of radiators, underfloor heating and other distribution branches.
Advantages
The design enables reliable hydraulic decoupling of three secondary circuits from a single primary source, supporting consistent flow distribution and stable temperature control across the installation. Its compact form factor allows integration in residential and small commercial boiler rooms where space is limited. Compatibility with standard air and dirt separators and straightforward pipe connections ease installation and maintenance without altering the core hydraulic balance of the system.
Suitable for
 Residential heating systems with multiple zones
 Small commercial buildings requiring up to 70 kW heat input
 Installations combining radiators and underfloor heating circuits
 Refurbishment projects that need hydraulic decoupling for existing boilers
Key specifications
 Capacity: for heat sources up to 70 kW
 Number of secondary circuits: 3
 Function: hydraulic separation between primary and secondary circuits
 Design: compact, space-saving body suitable for boiler-room installation
 Integration: compatible with air separator and dirt separator accessories for deaeration and filtration
How to use
Install the hydraulic separator in the piping layout between the heat source and the three secondary circuits, following the system schematic and local plumbing regulations. Provide inlet and outlet connections according to the flow direction markings and ensure correct orientation and support to avoid stress on pipe joints. Fit recommended air and dirt separation devices at the designated ports to remove entrained air and particles. Commission the system by purging each circuit, setting pump curves or flow controls as required, and verifying temperature stability and flow balance across all circuits.
Usage recommendations
Use compatible air and dirt separators to maximize system cleanliness and deaeration. During commissioning, balance flows in the three secondary circuits gradually and monitor differential temperatures to ensure proper hydraulic separation. Schedule periodic inspection of separators and flushing of collected debris according to local maintenance practices.
