1. An apparatus for cooling air and/or water, said apparatus comprising:
a first reservoir for holding a first water volume;
a second reservoir for holding a second water volume, wherein the first and second reservoir are in fluid communication with each other;
a heat rejection unit comprising at least one evaporative media, wherein air entering the heat rejection unit first passes through the at least one evaporative media before being exhausted;
a cooling unit comprising at least one evaporative media and at least one pre-cooler;
a first water circuit fluidly connecting the at least one pre-cooler and the at least one evaporative media of the cooling unit, the heat rejection unit, the first reservoir and the second reservoir;
a second water circuit fluidly connecting the at least one evaporative media of the cooling unit and the first reservoir and/or the second reservoir; and
a means for adjusting the water flow rate and/or volume through the first and second water circuit,
wherein the heat rejection unit and cooling unit are contained within separate housings, wherein each housing comprises one or more inlets for intake airflow and one or more outlets for exhaust airflow.
