As stated in its opening paragraph, CTI Standard 201... "sets
forth a program whereby the Cooling Technology Institute will
certify that all models of a line of water cooling towers offered for
sale by a specific Manufacturer will perform thermally in
accordance with the Manufacturer's published ratings..." By the
purchase of a "certified" model, the User has assurance that the
tower will perform as specified, provided that its circulating water is
no more than acceptably contaminated-and that its air supply is
ample and unobstructed. Either that model, or one of its close design
family members, will have been thoroughly tested by the single
CTI-licensed testing agency for Certification and found to perform
as claimed by the Manufacturer.
CTI Certification under STD-201 is limited to thermal operating
conditions with entering wet bulb temperatures between 12.8°C and
32.2°C (55°F to 90°F), a maximum process fluid temperature of
51.7°C (125°F), a cooling range of 2.2°C (4°F) or greater, and a
cooling approach of 2.8°C (5°F) or greater. The manufacturer may
set more restrictive limits if desired or publish less restrictive limits
if the CTI limits are clearly defined and noted in the publication.
