Heatexchangers
are used for heating or cooling of process media. There are various types available. We would like to introduce those out of our range of products: shell &
tube, brazed plate, plate & frame, plate heatexchanger panels as well as air blast coolers.
 The process fluid on Shell & tube heatexchanger is usually installed to the
shellside, whilst the cooling fluid is being connected to the tubeside; normally water (depending on the application) fresh-, sea- or brackish water.
The cooling fluid dissipates the heat of the process fluid by circulating counterflow through the tubeside via the inner surface of the tubes. These types of heatexchangers are available with an integrated expansion tank as well.
 Brazed plate heatexchangers consist of numerous profiled singleplates; special arrangement of these plates causes turbulent velocities, rendering them less prone to
fouling. There are two different kinds: brazed and plate & frame type heatexchangers. The way they are functioning is almost identical. Brazing forms an
integral unit, whilst at the plate & frame type uses gaskets instead.
 Airblast coolers are being used when there is no water for cooling available By using air as cooling medium it should be well considered that the
temperature, in dependence on the climate conditions, can be variable. The fans are propelled by electric motors. “Sucking type” fans are fitted, thus
obtaining better dissipation capacity. The amount of generated air is always proportional to the fan blades diameter and not to the speed of the same.
In contrast to the above mentioned design,
plate heatexchanger panels (PHP) can be fitted/ hanged directly into the process fluid,
clamped on from the outside, or even become a part of the vessel. They are manufactured from two two sheets of metal by laser or resistance welding, forming a series of passes through which the heating
or cooling media flows. The profile being created depends on the customer´s demand.
