About Testing
CTI STD-201 sets forth a program whereby the Cooling Technology Institute will certify that all models of a line of Evaporative Heat Rejection Equipment offered for sale by a specific Manufacturer will perform thermally in accordance with the Manufacturer's published ratings.
By purchasing a CTI Certified model, the owner/operator has assurance that the tower will perform as specified. Either that model, or one within its model line, will have been thoroughly tested by a CTI-licensed testing agency and found to perform as claimed by the manufacturer.
