Coils
The airside coil is connected to the heat pump
compressor(s) and is the primary vehicle for heating
and cooling of the building. A reheat coil is optionally
available and is installed in the supply airstream
adjacent to the airside coil. The reheat coil is also
connected to the heat pump but is used only when the
unit is in cooling mode.

Energy Wheel
The energy wheel rotates through both the outdoor air
and the exhaust airstreams, removing both sensible
(heat) energy and latent moisture from one airstream
and transferring it to the other airstream. The energy
wheel itself is comprised of segments which can be
removed for servicing.
