Greenheck Fan Corp.: Insulated Control DampersAvailable with a thermally broken frame, the ICD Series of insulated control dampers consists of ultra low-leakage dampers with thermally broken insulated blades. According to the manufacturer, the thermally broken frame provides an insulating barrier in the ductwork and the thermally broken blades separate the warm and cold air inside the ductwork. Four frame types are available: quick connect for easy connection to duct, channel, single flange, and reversed flange. The dampers are ideally suited for applications where minimal leakage and thermal transfer are required or when condensation on the damper blades is a concern, the company said. They have earned Air Movement and Control Association (AMCA) Intl. Inc.’s new certified energy-efficiency rating. This test method, which is found in American National Standards Institute (ANSI)/AMCA Standard 500D-12, assigns a damper a thermal efficiency ratio by comparing its thermal performance with the thermal performance of a standard reference damper. It is also AMCA-certified for pressure drop and leakage.
