Test Chamber

The Federal Bureau of Investigation (FBI), specifically the FBI-JEH office, issued this special notice under solicitation number SHOP-PR-26-001555 for the acquisition of a 40 cu.ft. Tenney Environmental Test Chamber and a TPS Model WIT 112 Chamber. The agency intends to negotiate a one-time, sole source, fixed-price contract with TPS LLC. This procurement is categorized under NAICS code 333994, Industrial Process Furnace and Oven Manufacturing, and PSC 3695, MISCELLANEOUS SPECIAL INDUSTRY MACHINERY, with an SBA (SBA) set-aside designation.

The FBI is pursuing a sole source award because TPS LLC is the exclusive manufacturer of these devices and does not authorize any other vendors to resell them. The equipment will support operations at the Ballistic Research Facility located at Redstone Arsenal, Alabama. The facility has utilized identical equipment from this manufacturer for decades, and the existing staff’s familiarity with the operating systems and precise controls ensures continuity in testing processes.

Responses to this notice are due by May 29, 2026. The primary point of contact for this requirement is Holly Cloud. One attachment, a PDF titled Notice of Intent_ TPS LLC_1555.pdf, was published with the notice on May 15, 2026. A copy of the formal sole source justification is available from the agency upon request.
