Dry Coolers

The National Renewable Energy Laboratory (NREL), an agency within the Department of Energy's Office of Science, is seeking dry cooler heat exchangers to support the operation of its existing Aries 10 MW low temperature electrolysis station. The Request for Quote (RFQ No. 2025022604) requires heat exchangers capable of rejecting 6 MW of heat using a 50/50 water/propylene glycol process fluid, with specific technical requirements including transportability, ASME rating, and outdoor installation suitability. This procurement will be conducted as a Lowest Price Technically Acceptable (LPTA) solicitation, meaning the government will select the lowest-priced offer that meets all technical specifications. Proposals are due by December 18, 2024, at 4:00 PM Mountain Time, with quotes to be submitted electronically to Christopher Ragain at NREL. The solicitation allows for either flatbed or V-type cooler configurations, with a preference for AC motors and specific requirements for continuous and variable load operations.

The contract opportunity is not set aside for any specific business category and is open to all qualified vendors in the Power Boiler and Heat Exchanger Manufacturing sector (NAICS 332410). The anticipated lead time for the award is approximately 6 months, with a targeted delivery date of June 2, 2025. The place of performance will be in Golden, Colorado, specifically at NREL's Flatirons Campus. Technical specifications mandate that the dry coolers must operate without water consumption, be powered by 480 VAC, 3-phase, 60 Hz electricity, and handle a process flow rate of 2,500 GPM with a target outlet fluid temperature of 45°C. While specific award value ranges are not explicitly stated, the procurement is for a single Firm Fixed Price purchase order. Vendors must be registered in the System for Award Management (SAM) and comply with federal regulations, including restrictions on certain telecommunications equipment.
