Form / Attachment / Pricing Sheet

This document, "Attachment 1 - Technical Specifications - Hydrogen Water Dropout Heat Exchangers," provides detailed technical specifications for ten heat exchangers (HX) required for the Multimegawatt (MMW) Electrolyzer project. These HXs will cool the hydrogen process stream. Bidders must use this document to understand the specific requirements for the heat exchangers to ensure their proposed solution meets the government's needs.

• Quantity: Ten (10) heat exchangers.
• Application: Cooling a hydrogen process stream saturated with water, using a 50/50 propylene glycol/water mixture on the cold side.
• Materials: Must be compatible with deionized water (1-17 MOhm-cm conductivity) and hydrogen. No sulfur-containing components in wetted sections. Metallic material to be 316/316L stainless steel. Soft sealing material to be FKM/Viton, PTFE, or Teflon.
• Pressure & Temperature Ratings: Specific Maximum Allowable Working Pressure (MAWP) and Maximum Allowable Working Temperature (MAWT) are detailed for different HX groupings (1-3, 4-5, 6-8, 9-10).
• Flow Rates & Pressure Drop: Specified hydrogen flow rates and maximum allowable pressure drops are provided for each HX group.
• Cleaning & Passivation: Hot sides of HXs must be electropolished or passivated per ASTM A967 or equivalent for Type I DI water service.
• Connections: 1.5 inch Swagelok compression fitting or 1.5 inch ANSI raised face flange fittings.
• Delivery: To NLR Flatirons Campus, Arvada, CO 80007.
• Timeline: Delivery preferred in August 2026, required by September 2026.

This attachment is critical for bidders to define their technical solution. It outlines the exact performance parameters, material requirements, and operational conditions the heat exchangers must meet. Failure to meet these specifications will likely result in a non-responsive bid. The detailed specifications for different HX pairs (e.g., HXs 1-3, HXs 4-5, HXs 6-8, HXs 9-10) indicate that variations in requirements exist within the total order, which bidders must address.
