About this file
This technical specification document details requirements for a 20kW air-to-water chiller to be used at the Electron-Ion Collider (EIC) at Brookhaven National Laboratory. The chiller must provide chilled water to heat exchangers in a rack for cooling power supply equipment, with specific performance parameters including a refrigeration capacity of 20kW, temperature control range of 15-20 degrees Celsius, and a 65-liter tank capacity. The unit requires 460V, 3-phase power, must be UL certified, and have maximum dimensions of 800mm x 1000mm x 1900mm.
The specification emphasizes environment, safety, and health considerations, requiring hazard identification and mitigation across all equipment lifecycle stages. The chiller must be a commercially available air-cooled model, not a custom design. The document is part of the EIC Project, which aims to design and install accelerator hardware including a new electron storage ring, electron injector, and modifications to the hadron ring. The specification was prepared by Dominic Prevosto, an Associate Staff Electrical Engineer at Brookhaven National Laboratory, with an effective date of 8/01/2025 and revision 00 status.

1 SCOPE
This specification defines the technical requirements for an air-to-water chiller capable of 20kW of cooling to be used at the Electron-Ion Collider (EIC) at Brookhaven National Laboratory (BNL) managed by Brookhaven Science Associates (BSA).
1.1 Background
The EIC Project will design, build, and install the accelerator hardware for a new electron storage ring, an electron injector, and modifications to the hadron ring required to produce an electron-ion collider and infrastructure. It will include one interaction region, with an allowance for a second, and one detector. The facility is designed to meet requirements to ensure high reliability and availability for the user program.
This chiller will be used to provide chilled water to heat exchangers in a rack to cool power supply equipment.
2 APPLICABLE DOCUMENTS
The following specifications, standards and drawings form a part of this specification to the extent specified herein. Unless otherwise specified, the applicable revision level of these documents shall be that in effect on the date of the solicitation or contract. Exceptions must be approved in writing by BSA.
In the event of a conflict between the applicable documents and this specification, the Contractor shall immediately notify the BSA Contractual Representative who shall in each instance determine which document takes precedence and advise the Contractor accordingly. Failure to notify BSA of a document conflict shall not relieve the Contractor’s responsibility to ensure full compliance to all requirements.
