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 comprises a main housing unit comprising a vent for air intake, a primary refrigeration system, consisting of 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 of the present invention comprises a secondary refrigeration system to remove heat resulting from the blower and may further comprise an additional tertiary refrigeration system located downstream of the secondary system to provide further cooling or heating to achieve the desired air temperature, and an outlet for connection to parked aircraft. The apparatus can provide independent temperature, air pressure and airflow to two aircraft or provide appropriate temperature, air pressure and airflow to one aircraft.
