The Department of Defense, through the NAVSUP Weapon Systems Support, is seeking to procure an evaporator unit (E2 15-ton) specifically from Honeywell International Inc., as this item is governed by source-controlled technical data. The procurement is limited to Honeywell due to the source control drawing owned by Northrop Grumman, which restricts the distribution of technical data to potential new suppliers. This evaporator unit is critical for refrigeration and air conditioning applications within military operations. Interested parties can reach out to Allen Neyland at 215-697-4314 or via email at allen.neyland@navy.mil for further information regarding this presolicitation opportunity.
