2 Air Compressors and One Air Dryer

This Statement of Work outlines the requirements for a Firm-Fixed-Price purchase order to supply two rotary screw air compressors and one continuous-duty, dual-tower, regenerative heated desiccant air dryer for the St. Stephen Powerhouse. The air compressors must be 30 HP, 480V, 3-phase with VFD controls, deliver at least 130 SCFM at 125 PSI, and include air-cooled heat exchangers and a top-opening enclosure. The air dryer must be 480V, 3-phase, rated for 250 CFM, maintain a -40 degrees F dew point at 100 PSIG, and include a three-valve bypass system. All items must be new, commercial-off-the-shelf and delivered to the St. Stephen Powerhouse at 1275 Rediversion Road, St. Stephen, SC 29479, Monday-Thursday during specified hours.

The ST Stephen Air Compressor project (STSAIRCOMP23) outlines the procurement of two 30HP, 480V air compressors and one 480V desiccant air dryer for the U.S. Army Corps of Engineers St Stephen Powerhouse. The document details technical specifications, supply and delivery requirements, and acceptance procedures. It also covers extensive submittal procedures, including various document types like shop drawings, product data, and test reports, emphasizing government approval for critical submissions. Additionally, the project mandates seismic restraint design for the new equipment, adhering to ASCE 7 and IEEE 693 standards, with specific requirements for concrete anchors. The file also includes comprehensive guidelines for the compressed-air systems, focusing on safety, quality control, manufacturer experience, factory testing, and operation and maintenance manuals.

The government's RFP W9127826A0005 details requirements for air compressors and an air dryer for a hydropower powerhouse. Key clarifications include the acceptance of a manual flow controller and the reuse of existing tanks, rejecting the need for new ones. A critical requirement is an air dryer outlet flow of 250 CFM at 100 PSI, with 215-223 SCFM being insufficient. The Buy American Act is in effect, prohibiting products originating from outside the US, which disqualified proposed Chinese products. Base-mounted compressors are preferred, utilizing existing receiver tanks. Both oil-free and oil-filled rotary screw compressors are acceptable. The compressors will be installed indoors in a climate-controlled facility, operating in a lead-lag scenario. Both heated and non-heated dryer options are acceptable.
