The Plettenburg Heat Exchanger in operation

The Plettenburg heat exchangers can be installed either inside or outside the barn.

For both options, shapes, sizes and dimensions are chosen to achieve an optimal heat recovery.

The centrifugal fan moves the outside air. This outside air passes through a stainless steel filter, through the inside of the plastic tubes towards the end of the heat exchanger. During its transportation through the system, the air is heated or cooled as desired.  When the outside air needs to be heated, the axial flow fans exhaust the warm shed air along the outside of the plastic tubes.
