Ice Harbor Dam Heatless Desiccant Compressed Air Dryer

The US Army Corps of Engineers Engineering District Walla Walla is procuring a heatless regenerative desiccant compressed air dryer system to replace an existing Zeks air dryer model 80 HPS at the Ice Harbor Lock and Dam facility. The procurement includes one heatless desiccant compressed air dryer with a 100 scfm flow rating at 100 PSIG capable of delivering air at ISO 8573-1 quality class 2 with a -40°F dew point, along with one high-efficiency coalescing pre-filter and one particulate after-filter. The system must feature dual tower regenerative design, fully automatic operation, UL certification, NEMA 7 rated electrical enclosure, and 125VAC power supply capability. The contractor must also provide spare parts including pilot filter elements and switching valve rebuild kits, plus four copies of comprehensive Operation and Maintenance Manuals. Following an amendment issued on September 23, 2025, proposals are now due by September 25, 2025 at 10:00 AM PDT, with delivery required within eight weeks of contract award and a final delivery date of December 9, 2025.

This procurement is designated as a 100% Women-Owned Small Business (WOSB) set-aside under NAICS code 339912 with a size standard of 1,000 employees, indicating the government's commitment to supporting women-owned enterprises in this specialized manufacturing sector. The contract will be awarded on a firm fixed price basis, though no specific budget range or award value has been disclosed in the solicitation documents. The place of performance is the Army Corps of Engineers Ice Harbor Lock and Dam facility located at 2763 Monument Drive, Burbank, Washington 99323, with delivery restricted to normal business hours Monday through Thursday from 7:00 AM to 4:00 PM, excluding federal holidays. The procurement involves replacing a single existing Zeks model 80 HPS air dryer system, suggesting this is a direct replacement project rather than a new installation or expansion of compressed air capacity at the dam facility.
