About this file
This is a Minimum Requirements Document for the procurement of two explosive-resistant friction ovens by the Air Force Research Laboratory (AFRL) Munitions Directorate at Wright-Patterson Air Force Base, Ohio. The ovens are required to dry and cure energetic materials and support aging studies on explosive materials, with existing equipment (six ovens, approximately 40 years old) becoming obsolete and requiring extensive maintenance. Only three of the current ovens remain operational.
The ovens must meet specific salient characteristics including intrinsically safe interiors capable of operating in Class I/Division I hazardous locations where flammable gases and vapors are present during normal operations. Required specifications include interior dimensions of approximately 37" width × 34" depth × 42" height; operating temperature range of 40°C to 90°C with a maximum capability of at least 120°C; uniform air circulation for heat distribution; and remote control capability from either Building 1247 or Building 1206 (over 300 feet away). The ovens must include three material trays (36" × 33" × 1" approximate dimensions) with 175-pound capacity each and space for additional trays, a purging system compliant with NFPA regulations for Class I and II, Groups D and E electrical enclosures, spare PLC and HMI dashboard components, and a minimum one-year warranty. All motors, hinges, and wiring must be rated for Class I/Division I operation. Delivery is to Building 1247 at Eglin AFB, Florida, as soon as possible, and the requirement is set-aside as a 100% Total Small Business contract under NAICS code 333994 (Industrial Process Furnace and Oven Manufacturing) with award based on Lowest Price Technically Acceptable criteria.

Minimum Requirements Document Explosive-Resistant, Friction Oven Equipment Purchase 26 April 2026
Scope: AFRL/RWTE request a contract to purchase two explosive-resistant, friction ovens. The ovens are required to dry and cure energetic material. The ovens also support aging studies on energetic material.
Background: AFRL/RWTE often stores energetic materials in liquid solutions to prevent inadvertent detonation. This material must be dried and cured prior to use in energetic formulations. The material needs to be dried in a timely manner is a way that does not increase the potential for detonation. Friction ovens were identified as the best way to complete the drying/curing process. AFRL/RWTE also uses the ovens to conduct studies on how aging affect explosive materials. The aging process can be accelerated by cycling material through a heating and cooling process over a period of time. The aging studies generally run for 6-7 months. Only 3 of the 6 ovens AFRL/RWTE has are operational and starting to require extensive maintenance to keep them operational. The present ovens are approximately 40 years old.
Requirements/Salient Characteristics: The following Salient Characteristics are firm requirements and any “or equal” item must meet these characteristics:
The oven requirements are:
1. The ovens will be located in Bldg 1247.
2. The oven's interior must be intrinsically safe. This means the ovens must be able to dry/cure material using equipment and procedures that will not cause ignition of the material in the oven.
3. The oven must be able to operate in a Class I/Division I area. A Class I/Division I areas are a high-risk location where flammable gases, vapors, or liquids are present in ignitable concentrations during normal, everyday operating conditions.
4. The interior dimensions should be approximately Width 37", Depth 34", and Height 42".
5. The operating temperatures of the ovens should a minimum of 40oC to 90oC.
6. The maximum oven temperature should be at least 120oC.
7. The ability to control the oven must in the same room in Bldg 1247 or remotely from Bldg 1206. Bldg 1206 is over 300ft from Bldg. 1247.
8. All motors, hinges, and wiring must be able to operate in a Class I/Division I area.
9. Air circulation in the oven will ensure uniform heat distribution throughout the oven chamber.
10. The ovens should come with three material trays with an approximate size of Width: 36", Depth 33" and Height 1" and have room for additional trays. The tray capacity should be 175 lbs each.
11. The consoles should have a purging system to comply with NFPA regulations for electrical enclosures in a Class I and II, Groups D &E environment.
12. A spare Programmable Logic Controller (PLC) and spare Human-Machine Interface (HMI) dashboard will be provided.
12. A minimum 1 year warranty will be provided.
