From September on NRF further expanded and improved their Bar & Plate product range. 80mm core thickness is now available as express core for water, oil and charge air.
On top of that all NRF Bar & Plate cores are equipped with the NRF hemmed fin.
The hemmed fin significantly increases the strength of the leading and trailing edges by a factor greater than just the doubling of the material. It endures far more aggressive cleaning pressures without measurably increasing the air pressure drop. It greatly reduces the current risk of conventional fin damage during cleaning trackside or scheduled service intervals.
