The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure dehumidifier assembly and other replacement parts under a presolicitation notice. The procurement involves a specific National Stock Number (NSN 7H-4440-016207374) with a quantity of 9 units, which must be sourced from designated suppliers due to the lack of available technical data or rights for alternative sourcing. This equipment is critical for maintaining operational efficiency and reliability in naval systems. Interested parties are encouraged to contact Aryel Ryan at (717) 605-4614 or via email at ARYEL.A.RYAN.CIV@US.NAVY.MIL for further details, noting that this opportunity is set aside for small businesses and is not open for competitive proposals.
