Abstract: An adiabatic condenser or fluid cooler is provided. A condensing or fluid cooling coil is provided. An adiabatic pad is provided wherein water can be used to cool the ambient air before entering or impacting the condensing or fluid cooling coil. Controls are provided that can adjust or eliminate the amount of water flowing over the adiabatic pad. The adiabatic pad may also be physically moved to allow ambient air to directly impact the condensing or fluid cooling coil.

Abstract: Disclosed is a DC electrical power generation system mounted on a rescue vehicle, the rescue vehicle having a prime mover controlled by a prime mover controller and a power take off operable to transfer rotational energy from the prime mover. The DC electrical power generation system comprises a DC electrical generator having a generator input connected to the power take off and operable to produce DC electrical energy at a target voltage when rotated at a target speed. The DC-DC converter has an input connected to the output of the DC electrical generator and is operable to convert a generator output voltage of the DC electrical generator to a voltage suitable for charging an electric vehicle when a battery pack of the electric vehicle is connected to the output of the DC-DC converter.
