The U.S. Coast Guard requires five fan coil units (NSN: 4120-01-F20-6132) for use on 154' WPC vessels, with delivery to Baltimore, MD 21226. Only genuine OEM parts from Walter Roller GmbH & Co. or its authorized distributors are acceptable, and substitute parts are not allowed. Quotations must be FOB Destination, and strict military-standard packaging, packing, marking, and bar-coding are mandatory—standard commercial packaging will be rejected. The government intends to award a single firm-fixed-price purchase order on a lowest price technically acceptable basis, with a response deadline of two calendar days from the notice posting. Interested parties must be registered in SAM, provide a valid DUNS number, and include an OEM authorization letter verifying they can supply genuine parts.
