Brass magnetic dirt separator 3/4" for central heating boilers, fixed connection

Product detailed description

Magnetic dirt separators are essential components in central heating systems where boiler efficiency and longevity depend on clean circulating water. In residential and commercial buildings with conventional heating boilers, these devices help prevent damage from suspended ferromagnetic particles. Installers commonly encounter magnetite and other metallic debris in heating circuits, which can accumulate in heat exchangers and reduce thermal efficiency. This compact 3/4 inch model is ideal for smaller heating systems where a 1 inch body would be oversized.

When integrating into a central heating system, the separator is typically installed on the return line just before the boiler. This positioning ensures that all circulating water passes through the magnetic field before reaching sensitive components. The fixed connection design eliminates the need for additional fittings, streamlining installation in tight mechanical rooms or boiler houses.

Technical parameters

Type	Magnetic dirt separator, fixed
Connection thread	3/4 inch
Max. temperature	≤ 110°C
Max. pressure	≤ 1.0 MPa (10 bar)
Code	SEP.MAG.3/4S
Brand	Hydroland

The maximum operating temperature of 110°C and pressure rating of 10 bar make this model suitable for standard central heating applications. The 3/4 inch thread size is appropriate for smaller pipe diameters typically found in residential and compact commercial systems. These parameters are critical for ensuring compatibility with existing pipe sizes and system operating conditions.Installation and connection The fixed 3/4 inch threaded connection requires no additional adapters for standard central heating pipe sizes. Installers should ensure the separator is positioned on the return line with the flow direction indicated on the body. A common mistake is installing the unit on the supply line, which can reduce its effectiveness. Verify that the installation location allows for easy access during maintenance. The unit should be installed with a slight slope to facilitate debris collection at the bottom of the magnetic chamber.

Compatibility and accessories

This magnetic dirt separator is specifically designed for central heating circuits and is not suitable for domestic hot water systems. It is compatible with standard brass pipe fittings and valves of 3/4 inch size. No additional accessories are required for operation, as the unit has no replaceable filter inserts. Installers should ensure that the boiler system is sized appropriately for the separator's flow capacity.

Technical background for designers

The operating principle is based on magnetic attraction: ferromagnetic particles in the circulating water are captured by the internal magnet. The brass body provides good corrosion resistance for long-term use in closed heating systems. The fixed connection ensures a secure seal without the need for gaskets or O-rings. The efficiency of the unit depends on the flow velocity and the concentration of ferromagnetic particles in the water. Proper integration into the system ensures continuous protection of heat exchangers and circulators.

Service and operation

During boiler service, the collected debris can be manually removed from the magnetic chamber. The unit has no replaceable parts, so it can be immediately returned to service after cleaning. No scheduled maintenance intervals are specified, but it is recommended to inspect the unit during routine boiler servicing. A visual inspection of the magnetic chamber will indicate the need for cleaning.

Frequently asked questions

Can this separator be used in a domestic hot water system?
No, it is specifically designed for central heating circuits and is not suitable for domestic hot water applications.

Does the unit require a filter insert for operation?
No, it has no filter insert and relies solely on the magnetic field to capture ferromagnetic particles.

Can this model be installed on the supply line of a boiler?
It is recommended to install the unit on the return line just before the boiler to ensure all circulating water passes through the magnetic field.

Is this model suitable for high-pressure heating systems?
It is rated for a maximum pressure of 10 bar, making it suitable for standard central heating systems.
