Condenser - This coil takes the superheated vapor from the compressor and cools that vapor down to saturation. It then completely condenses all of the vapor into liquid, and continues to subcool the resulting liquid to a desired temperature below saturation.

Reheat - This is a hot gas reheat coil which takes the superheated vapor from the compressor and cools the vapor down to saturation. It then continues to condense a requested percentage of that vapor to a liquid.

Desuperheater - This coil takes the superheated vapor from the compressor and cools that vapor down to a requested temperature above saturation.
