The Department of Homeland Security, specifically the U.S. Coast Guard, is seeking quotations for the procurement of five heat exchangers, identified by NSN 3040-12-382-2887, from the manufacturer Zahnradsfabrik Friedrichshafen. The procurement requires strict adherence to packaging and marking standards, including compliance with MIL-STD-2073-1E and ASTM-D-6251, to ensure the items are protected during transit and storage. These heat exchangers are critical components for the Coast Guard's operational readiness, and the contract will be awarded based on the lowest price technically acceptable criteria. Interested vendors must submit their quotations by October 28, 2024, at 10:00 AM EST, and direct inquiries to Yvette R. Johnson at YVETTE.R.JOHNSON@USCG.MIL.
