A new brochure details the manufacturer's low-leakage insulated control damper (Model ICD). Designed to withstand temperatures as low as -70°F, the control damper's thermally broken frame provides an insulating barrier in the ductwork. Ideal for outdoor air intake systems, Model ICD provides greater value in a building by significantly reducing the transfer of heat or cold and virtually eliminating condensation, states the company. The brochure includes damper performance testing criteria, construction features, and frame options.
