About this file

This is a Single Source/Brand Name Justification document for a simplified acquisition submitted by the USDA Federal Grain Inspection Service (FGIS), Technical Services Division (TSD) to the USDA APHIS Midwest Regional Program Based Support office in Minneapolis, Minnesota.

TSD is procuring a Tenney Cevo-20S Environmental Test Chamber and accessories from Thermal Product Solutions (TPS) to replace its current Tenney Environmental Chamber Model T20S-2.0 with 942 Controller, purchased in 1993 and now beyond its lifecycle. The equipment is necessary to meet technical requirements specified in NIST Handbook 44 and NCWM Publication 14 for grain moisture meters and near infrared grain protein analyzers. The chamber must meet specific performance criteria including a 20 cubic-foot capacity, air-cooled controller, temperature range of -32°C to 180°C with ±1.0°C fluctuation, Ethernet and RS485 communications, UL508A control panel, 230V/240V single-phase 60 Hz power supply, interior dimensions of 30 x 32 x 36 inches, and include two lead-in ports, leveling casters, and one shelf.

Market research identified competing vendors including Thermotron, ESPEC, Weiss Technik, CTS GmbH, and BINDER, but concluded that Tenney is the only viable option. Alternative chambers either fail to meet all specifications, are physically too large for available lab space, or require unavailable power infrastructure (3-phase AC or 480V supply). Replacement parts for the existing chamber are unavailable from other sources. The justification notes that testing requires the ability to fit entire instruments within the chamber's interior space, preferably two simultaneously for expedited testing. Pricing is based on TPS Quote No. 237705 revision 0, including a NIST certificate of calibration option, plus estimated shipping and installation costs. The acquisition was approved and electronically signed by Contracting Officer Latisha Hollman on August 10, 2026.

Template for Single Source or Brand Name Justification under SAT, March 2019

Single Source/Brand Name Justification United States Department of Agriculture

FAR 13.106-1(b)(1) – Simplified Acquisitions

1. Identification of the agency and the contracting office.

Requesting Agency:

USDA, FGIS, TSD

10383 North Ambassador Drive

Contracting Office:

USDA APHIS MRPBS AAMD

250 Marquette Ave Minneapolis, MN 55401

2. Description of supply or service required to meet the agency’s needs.

Purchase of a Tenney Cevo-20S Environmental Test Chamber and accessories from Thermal Product Solutions (TPS)

3. The rationale or circumstances for limiting competition.

TSD is purchasing the equipment necessary for providing the ability to meet the technical requirements as outlined in National Institute of Standards and Technology (NIST): Handbook 44 (Grain Moisture Meters and Near Infrared Grain Protein Analyzers) and National Conference on Weight and Measurements (NCWM): Publication 14 (Grain Moisture Meters and Near Infrared Grain Protein Analyzers/ Technical Policy/ Checklists and Test Procedures).

TSD currently utilizes Tenney Environmental Chamber Model T20S – 2.0 with 942 Controller, which was purchased in 1993 and has outperformed its lifecycle.

Minimum requirements:

• Environmental Test Chamber, 20 cu.ft.

• Controller, Air Cooled

• Chamber Temperature Unit: °C

• Optional Extended Temperature Range: No

• Condenser Type: Air

• Computer Interface: Ethernet & RS485 Communications (Standard for

• Smart 1.2)

• Control Panel: UL508A

• TempGard High/Low Limit Over/Under Temperature Protection

• 2 lead-in ports

• leveling casters

• one shelf.

• Temperature Range: -32°C to 180°C

• Temperature Fluctuation: +/- 1.0 Deg C measured at control sensor

• Humidity Range: Not applicable for this style chamber

• Interior Dimensions W x D x H (inches): 30 x 32 x 36

• Exterior Dimensions W x D x H (inches): 40 x 71 x 77.5

• Crating Dimensions W x D x H (inches): 46 x 77 x 83.5

• Electrical Power: 230V/240V 1 Phase 60 Hz

• Amp Draw: 32

• Amp Fuse: 40

4. A description of the market research conducted and the results or a statement of the reason market research was not conducted.

An internet search was completed for Tenney Cevo-20S Environmental Test Chamber. Purchase of any other environmental chambers would not meet all specified requirements and incur significant resources for TSD to remedy the problem. A review of Thermal Product Solutions (TPS) replacement parts vendor for the current Tenney chamber resulted in no compatible parts for potential repairs. Other replacement options provide similar performance yet are too large for exterior dimensions to fit lab space.

Additionally, testing requires that entire instruments fit within the interior space of the environmental chamber, preferably two at once for expedited testing. Further, other options require special power requirements that NGC does not possess (3-Phase AC power or 480V supply).

Various vendors offer this product for purchase including Thermotron, ESPEC, Weiss Technik, CTS GmbH, and BINDER.. Tenney is the only viable option. As mentioned above, all other vendors do not offer products that meet specifications.

5. Estimated price, including all options, if applicable.

The price of the Cevo-20S plus NIST certificate of calibration option.is based on TPS Quote No. 237705 revision 0. An additional amount may be added as a shipping and installation estimate.

6. Recommended source(s).

Recommended source – TPS

Notes and Guidance. Delete these Notes prior to finalizing document for signature

For acquisitions greater than the micro-purchase threshold but less than the Simplified Acquisition Threshold (SAT) the Contracting Officer may solicit from one source only if the Contracting Officer determines that the circumstances of the contract action deem only one source reasonably available (e.g., urgency, exclusive licensing agreements, brand name, etc.). Contracting Officers must document the rationale for soliciting from a single source, including brand name in accordance with FAR 13.106- 1(b)(1)(i) and FAR 13.106-3(b)(3)(i).

Program personnel are advised to work with contracting personnel early on in order to promote and provide for full and open competition to the maximum extent practicable. In circumstances permitting other than full and open competition, program personnel shall provide necessary information to contracting personnel to support and document the circumstances limiting competition through the use of this form

Advance planning. Contracting without providing for full and open competition shall not be justified on the basis of (1) a lack of advance planning by the requiring activity or (2) concerns related to the amount of funds available to the agency or activity for the acquisition of supplies or services.

Brand Name. Items peculiar to one manufacturer can be a particular brand name, product, or feature of a product, peculiar to one manufacturer. A brand name item, whether available on one or more schedule contracts, is an item peculiar to one manufacturer. Brand name specifications shall not be used unless the particular brand name, product or feature is essential to the Government’s requirements and market research indicates other companies’ similar products, or products lacking the particular feature, do not meet, or cannot be modified to meet the Agency’s needs.

Posting. When an acquisition contains brand name specifications, the Contracting Officer shall include the justification required by FAR 13.103-1(b) with the solicitation when synopsizing in the GPE (actions exceeding $25,000) or displaying in a public place (actions exceeding $15,000 but not expected to exceed $25,000), as required by FAR 5.102(1)(6).

Screening. Before posting the justification, in accordance with FAR 6.305(e) and 24.202, the Contracting Officer is responsible to redact any information that is exempt from disclosure under Freedom of Information Act or information proprietary to the contractor.

Signatures. After review and completion by the Program Office and Contracting Officer, the Word document shall be converted to an Adobe PDF file and routed for electronic signatures. Signature blocks shall include dates.
