AAON is implementing a new Modulating Hot Gas Reheat Strategy, using Parallel Reheat in place of the standard Series Reheat.
Their new piping sequence allows the Reheat Coil to be parallel to the Condensing Coil, taking the Condenser out of the loop. This leads to more capacity out of the Reheat Coil, while easily maintaining head pressure.
AAON can also reheat using all compressors, or just the LAG Compressor. This gives greater control of cooling during dehumidification.
