An apparatus for providing preconditioned air to at least one aircraft parked on the ground wherein internal heat exchangers lower or raise the discharge air temperature. The apparatus uses a main housing unit having a vent for air intake, a primary refrigeration system using a primary intake coil to precool or preheat the air in a primary intake plenum serving two blower intakes and two separate and independent blowers. Each blower discharge is then directed to a separate secondary plenum. Each secondary plenum uses a secondary refrigeration system to remove heat resulting from the blower and may further use a tertiary refrigeration system located downstream of the secondary system to provide further cooling or heating to achieve the desired air temperature. Each secondary plenum has an outlet for connection to parked aircraft. The apparatus can provide independent temperature, air pressure and airflow to two or more aircraft or provide appropriate temperature, air pressure and airflow to one aircraft.
