Double Level Counterflow Cooling Tower Conversion

Patented in 1989, this design effectively increases the cooling capacity of a Cross Flow Cooling Tower by converting the tower internals to a counterflow configuration. Internally, what was originally a cross flow cell is converted to 3 counterflow cells. New supply piping is run off the existing return header to supply water to each of these cells. The larger, bottom level, cell has the same cooling capacity as the original cross flow cell, and it’s air is supplied by the existing fan. The 2 smaller cells, installed in the upper elevations, with additional fans installed at the original location of the hot water decks, add additional cooling capacity. Water which flows out of these smaller cells drains directly to the basin.
