The Plettenburg Heat Exchanger in operation
The Plettenburg heat exchangers can be installed either inside or outside the barn.
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.
