The Cooling Technology Institute announced its thermal performance certification program for adiabatic fluid coolers is anticipated to launch this summer as part of its existing certification program based on CTI Standard 201.
This well-established program currently includes open- and closed-circuit cooling towers and dry fluid coolers. Both forced and induced draft, adiabatic pad-type fluid coolers will be covered by this new certification program, cooling either water or aqueous glycol solutions. By purchasing a CTI-certified model, an owner/operator has assurance their heat rejection device will perform thermally as specified.
Currently, there are 113 manufacturers along with 34 private brand affiliates participating in the Thermal Certification Program across the globe. The program covers 305 certified open- and closed-circuit cooling tower and dry cooler product lines available to the market, comprising a total of over 93,000 individual models. All manufacturers that are interested in certifying either their cooling tower, dry cooler or adiabatic fluid cooler product lines are invited to do so by filling out the thermal certification inquiry form.
The current versions of STD 201 OM (operations manual) and STD 201 RS (ratings standard) documents are available for a nominal charge on the CTI Marketplace. Also available are the associated Acceptance Test Codes (ATC), such as ATC 105 DS for dry coolers and ATC-105 Adiabatic for adiabatic fluid coolers.
