Improved means for powering and increasing evaporative cooling in an indirect-direct evaporative cooling (IDEC) apparatus are disclosed. Sustainable energy from solar energy mixed with grid power, when needed, power the IDEC device. These DC and AC power sources are seamlessly merged in a unique diode interconnect unit. Improved means for evaporative cooling include a rayon-based flocking on the wet side of molded plastic indirect evaporative cooling plates. Separate wet and dry passages through those plates are facilitated by a unique means for clamping the upper ends of the plates.
