The Department of Homeland Security, specifically the U.S. Coast Guard, is seeking quotations for the procurement of twenty Terminal Ventilation Ducts, essential components for the ventilation systems of 45-foot RBM vessels. These ducts must meet specific requirements, including an aluminum frame, stainless steel linkage, and silicone rubber blade seals, and are critical for maintaining operational safety and efficiency. The procurement is limited to a sole source, CENTEK INDUSTRIES, INC., due to the proprietary nature of the required specifications and the absence of equivalent products, ensuring compatibility and safety during operations. Interested vendors must submit their quotations by May 5, 2025, and can contact Yannick Kassi at Yannick.A.Kassi@uscg.mil for further details.
