About this opportunity
The Department of the Army Corps of Engineers Engineering District Seattle is seeking to procure a Medium Frequency 50kW Mobile Induction Brazing System for the Chief Joseph Dam location in Bridgeport, Washington. The system must include a power supply capable of delivering 50kW at continuous duty, with specific technical requirements such as electronic impedance matching, 480V 3-phase power input, and a minimum power supply efficiency of 90%. The system must also include three specific fork-type induction coils designed for brazing copper in varying lengths and configurations, a chiller, and a mobile cart with lockable wheels and crane pick points. The pre-solicitation notice was posted on April 25, 2025, with responses due by May 9, 2025, indicating a relatively short response window for potential vendors. While specific evaluation criteria are not explicitly detailed, the comprehensive technical specifications suggest that compliance with the prescribed technical requirements will be a primary assessment factor.
The contract opportunity is designated as a Total Small Business set-aside, which means only small businesses are eligible to compete for this procurement. The proposed system will be shipped directly to the US Army Corps of Engineers, specifically to Mikal Miller at the Chief Joseph Dam location. The NAICS category for this procurement is 332811 (Metal Heat Treating), with a Product Service Code of 3424 for metal heat treating equipment. No specific award value or budget range is mentioned in the pre-solicitation notice, nor are there details about potential incumbent contractors. The technical specifications indicate a highly specialized piece of equipment with precise requirements for power delivery, induction coil configurations, and mobility, suggesting that only vendors with specific manufacturing capabilities will be able to meet the government's needs.
Notice text
The vendor shall provide a Medium Frequency 50kW Mobile Induction Brazing System to the specifications listed below. All components shall be new, and the Induction Brazing System shall be shipped to: US Army Corps of Engineers, ATTN: Mikal Miller, Chief Joseph Dam, HWY 17 and Pearl Hill Road, Bridgeport, WA 98813. The Induction Brazing System shall consist of a 1) Induction Power Supply, 2) Induction Coils, 3) Chiller, and 4) Mobile Cart. Specifications for each component are listed below:
Induction Brazing System Specifications
Induction Power Supply Specifications:
Must be able to provide a minimum of 50kW at 100% continuous duty.
Must have electronic impedance matching for maximum power delivered over different induction coil configurations and work piece dimensions.
Must be able to accept input power from 480V 3-phase outlets, 60Hz. The system may accept power from multiple circuits, however the current from each individual circuit must not exceed 100A.
Must include a handheld brazing tool with pushbutton on/off.
Must have flexible power cable between power supply and handheld brazing tool of at least 30 feet.
Must have power supply efficiency of a minimum of 90%.
Must be able to generate an inductive frequency of at least 35kHz with self-tuning capability for optimizing frequency.
Power shall be regulated using a PLC.
Induction Coil Specifications:
Must include at least three induction coils.
One coil shall be a fork-type induction coil designed for brazing copper that is 5.5" long and 0.75" wide.
One coil shall be a fork-type induction coil designed for brazing copper that is 2.75" long and 1.25" wide.
One coil shall be a fork-type induction coil, with a 45-degree bend, designed for brazing copper that is 2.75" long and 1.25" wide.
Chiller Specifications (Must include at least three induction coils):
One coil shall be a fork-type induction coil designed for brazing copper that is 5.5" long and 0.75" wide.
One coil shall be a fork-type induction coil designed for brazing copper that is 2.75" long and 1.25" wide.
One coil shall be a fork-type induction coil, with a 45-degree bend, designed for brazing copper that is 2.75" long and 1.25" wide.
Mobile Cart Specifications:
Must include a mobile cart that allows the inductive power supply and cooking system to be moved together on the same cart. A system where the inductive power supply moves relative to the cooling system is not acceptable.
Mobile cart must allow staff to move brazing system across a flat surface without using other equipment.
Cart must have lockable wheels.
Cart must have pick points for movement by crane.
