The 19 CES needs an exact brand-name replacement Valent ERU-I energy recovery unit (VXC-112PL-7B-1-A3) to replace the existing VRP-IIO-IOJ-XXE-C-IDX unit in place. A complete quote must include the solicitation with pricing and quote details, plus all required provisions and clauses, though FAR 52.212-3 may be skipped if the annual SAM certification is complete. Vendors must have an active SAM registration at quote submission and maintain a Cage Code in SAM.gov with their company name. Award will be made based on price and technically acceptable. Questions are due by September 15, 2026 at 8 AM CST.
