Fa-210-156 – flanged plate heat exchanger 3" DN80 with 32.76 m² area
DN80 flanges and 156 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-210-156 heat exchanger has 156 plates and at the same time a larger connection than the models in the series with up to 108 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.
Below is a comparison of the Fa-210-108 (the largest model with DN65 flanges) with the Fa-210-156 featured in this offer:

Which systems is the Fa-210-156 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-210-156 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-210-156
Can I connect the Fa-210-156 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.
Is there a larger model in the series?
No – the Fa-210-156 is the largest model in the Fa-210 series. If you need a larger heat transfer area, contact us – we will propose a solution, e.g. two heat exchangers operating in parallel.
