Precision drawn profiles, or spacer bars, are used in plate-and-bar heat exchangers. Such heat exchangers can be built entirely in aluminium. This versatile concept is typically used in heavy equipment, due to its ability to withstand relatively high wear and tear, and for its high corrosion resistance.
The aluminium spacer bar is extruded and drawn under carefully controlled conditions. We usually supply these parts in long lengths, in a temper that allows you to handle the parts without bending them. You then cut the parts into the length needed.
The technology offers this solution high degrees of flexibility, so that the heat exchanger can be fitted to the actual need, even in low volumes.
The plates are used as building blocks in plate-and-bar heat exchangers. They are normally the final pieces added. Consequently, achieving the dimensional tolerances is critical, because any deviations from the nominal target will be multiplied by the number of profiles used in the application.
In typical plate-and-bar designs, you will adjust the length of the “block” to fit the depth of the heat exchanger, and adjust the “long bar” to the length.
