The development of NPF, a cooling tower fill, is described. This has low fouling characteristics whilst retaining thermal performance. NPF consists of PVC sheets bounded together into blocks. The sheets have triangular primary corrugation. Each sheet also has small-scale secondary ridges. The first installation has recently taken place in a 300MW cooling tower at Didcot Power Station, England. This demonstration installation and improvements achieved over the packing previously installed in that tower will be described.
