Plate Heat Exchanger NORDIC Ba-115-110 2" 3900kW

The Nordic Tec heat exchanger with 110 plates is designed for counter-flow operation

During the installation of the heat exchanger mentioned above, whether in a heating or cooling system, it's important to remember that this is a classic counter-flow heat exchanger, like all Nordic Tec plate heat exchangers. This means that for the supply connection, we can choose any channel, but regardless of this choice, the fluid in the second channel must flow in the opposite direction to the supply channel. In other words, the fluids in the two channels of the plate heat exchanger must flow in opposite directions.

Ignoring the counter-flow principle remains a common mistake in heat exchanger installations and primarily leads to reduced heat transfer capacity. It's estimated that a plate heat exchanger connected in so-called "parallel" mode (with both fluids flowing in the same direction) loses about 30-40% of its efficiency. Only heat exchangers specifically designed for parallel flow should be connected this way, and the manufacturer should clearly specify this.
