A test code for air-cooled fluid coolers — more commonly referred to as dry coolers — has been published by Houston-based Cooling Technology Institute. Its application is limited to the sensible cooling of water, aqueous glycol solutions and other homogeneous, single-phase process fluids. ATC-105DS applies to testing in both field and laboratory settings.

“This new test code will help owners and operators of dry coolers confirm that the actual performance matches both the thermal and pressure drop performance as stated by the manufacturer as well as complies with applicable energy-efficiency requirements,” said Jennifer Hamilton, chair of CTI’s 105DS Task Group.

Members of the task group that developed the document included representatives from all stakeholder groups, including owners and operators of heat-rejection equipment, manufacturers, test agencies and certification organizations. ATC-105DS is now available for a nominal charge.
