Nordic Tec · first model with DN80 flanges
Fa-210-120 – flanged plate heat exchanger 3" DN80 with 25.20 m² area
From this model on, the Fa-210 series switches to DN80 flanges. The larger connection bore and 120 plates are the choice for systems in which DN65 pipework is no longer sufficient and the heat demand has already reached industrial scale.

DN65 or DN80 flange – what changes?
The Fa-210-120 heat exchanger has 120 plates and at the same time a larger connection than the models in the same series with fewer plates. The housing and height are the same across the whole series, as all models are based on the same plate size. The difference lies in the size of the flanges (connection flanges) and the number of plates – and therefore in the flow rate and capacity the system can handle.

Which systems is the Fa-210-120 suitable for?
01
Boiler rooms with DN80 pipework. If the main pipes of the boiler room have a diameter of 3", the heat exchanger with DN80 flanges is connected without narrowing the bore and without additional pressure losses at reducers.
02
District heating substations for housing estates and large buildings. System separation between the district heating network and the building installation at high flow rates – e.g. in apartment buildings, office buildings, hospitals or halls.
03
Industrial processes and heat recovery. Separation of process and heating circuits, cooling or use of waste heat – wherever the media are water, water with glycol or similar.

What you need for installation
■ 4 DN80 counter flanges according to EN 1092-1, PN10 or PN16
■ DN80 flat gaskets plus bolts with nuts
■ Shut-off valves and strainers on both circuits
■ level floor or foundation for the support legs (included)
Operating conditions – what to bear in mind
The Fa-210-120 works exclusively in liquid-liquid systems. It is not intended for gases, F-gases and refrigerants, nor for media that attack stainless steel or copper – untreated water, well, rain, river, salt or demineralised water. It is not used in swimming pool systems – for those, pool heat exchangers (shell-and-tube heat exchangers) should be used.
Questions about the Fa-210-120
Can I connect the Fa-210-120 to a system with DN65 pipes?
Technically yes – using DN80/DN65 flange reducers. However, if the entire system has a DN65 bore, the Fa-210-108 is usually the better choice, as it has DN65 flanges and requires no reduction – provided its other properties, especially the heat transfer area, are taken into account.
How does a DN80 flange differ from a DN65 flange?
The DN80 flange has an outer diameter of 200 mm and a bolt circle of 160 mm (DN65: 185 and 145 mm). The larger bore reduces the flow velocity of the medium and the resistance at the connections.
What is the next model in the series?
The Fa-210-132 with 132 plates and 27.72 m² of area, also with DN80 flanges. The largest model, the Fa-210-156, has 32.76 m².
