Field of application

The HerzMag is installed in the heating circuit. It is used to filter out iron impurities and bleed off air. This prevents malfunctions and damage to heating and cooling systems. High efficiency for the whole heating system is ensured. Using the HerzMag ensures permanent, trouble-free air venting.

Functional principle OPERATION

The air vent is integrated into HerzMag for the separation of air. The shape of the HerzMag has been specially developed in order to reduce sensibly the flow speed. As a consequence air and microbubbles can raise and are evacuated through the air vent. In the same way, the iron impurities are directed to the outlet located on the bottom of the device, which is equipped with a drain valve. This is also supported by the magnet, whose position allows a perfect catching function.

It is preferably installed on the return circuit upstream after the radiator before the boiler and circulation pump so that the particles can be caught before they reach the boiler and circulation pump. When installing in the system, it is necessary to consider the flow's direction, which is shown on the brass T - piece.

Operating data

Operating temperature	0-90°
Medium	Heating water quality according to ONORM H5195 or VDI-Standard 2035. The use of ethylene or propylene glycol in a mixing ratio 25- 50% is allowed. Please refer to manufacturers documentation when using ethylene glycol roducts for frost and corrosion protection. Please note that EPDM gaskets will be affected by Mineral oils lubricants and thus lead to failure of the EPDM seals in the valves that use EPDM seals. The HERZ ball valve for heating and chilled water is not suitable for usage of agressive medium (such as: acids, alkalis, combustible and explosive gases..) because it can destroy sealing components.
Operating pressure	PN 3 bar

Special product features

1. Air Separator and dirt Separator: The velocity of the liquid when entering the filter is significantly reduced due to the
specially designed construction of the housing and the inner insert. This allows dirt and metal particles to accumulate on
the bottom of the housing. At the same time, air bubbles are formed, which accumulate on the top of the housing. Only
these are released from the housing with the venting valve.
2. Integrated Magnet: for the collection of ferromagnetic particles, which are in the water. Separation without draining
the system is possible.
3. Rotatable Connector: the separator can be mounted in any angle of the pipeline.
4. T piece with 360 degree adjustment: heavy duty construction made from high quality brass
5. Drain and filling valve: it is rotatable 360° and it serves to drain, clean or fill the heating system.
