Nordic Tec · largest model with DN65 flanges
Fa-210-108 – flanged plate heat exchanger DN65 with 22.68 m² area
108 plates is the maximum the Fa-210 series offers with 2.5" connections. If the system already has DN65 pipework and fittings, the Fa-210-108 delivers the largest possible heat transfer area – without converting the pipework to DN80.

Fa-210-108 DN65 compared with the smaller Nordic Tec flanged heat exchangers
All four models have the same flanges, the same connection spacing and the same height. They differ in the number of plates – and therefore in heat transfer area and depth.
When is the Fa-210-108 flanged heat exchanger the right choice?
Upgrading a boiler room with DN65 pipes
You are replacing an old heat exchanger or increasing the capacity of the substation, while the DN65 pipework and fittings remain. The heat exchanger is installed without modifying the fittings.
Area reserve at low temperatures
With a small temperature difference between the circuits, more heat transfer area is needed. 22.68 m² helps maintain the output even at a lower flow temperature.
High hot water demand
Apartment buildings, hotels, sports facilities and production plants with high domestic hot water consumption.

Plate material
AISI 316
Stainless steel with added molybdenum and higher corrosion resistance than standard 304 steel. It is recommended where the water quality in the system is harder to maintain. However, it does not replace water treatment. The product is not intended for groundwater.
What data do we need for the selection?
1Required heat exchanger capacity in kW
2Flow and return temperatures on the primary and secondary side
3Type of medium – water or glycol (type and concentration)
4Permissible pressure drop on both sides
Operation and safety
Cleaning. Thanks to the flanges, the heat exchanger can easily be disconnected for chemical flushing. Shut-off valves on both sides keep this to a minimum. Regular descaling protects against loss of performance and leaks.
Media. For liquid-liquid circuits only. The classic application is water or water with glycol. The heat exchanger is not intended for gases, F-gases and refrigerants, nor for untreated water, well, rain, river, salt or demineralised water. It is also not intended for heating swimming pools.
Questions about the Fa-210-108
Why is there no DN65 model with more plates?
This is how the Fa-210 series is structured: models up to 108 plates have DN65 flanges, from 120 plates larger DN80 flanges are used to suit the larger plate packs.
I need more than 22.68 m² – which model?
Next up is the Fa-210-120 with DN80 (3") flanges and 25.20 m². The largest model in the series, the Fa-210-156, has 32.76 m².
How much space is needed for installation?
The plate pack itself measures 319 × 736 × 275 mm, and the footprint with support legs is 358 mm wide. The flanges protrude at the front and rear – so also allow space for the counter flanges and free access to the bolts on both sides.
