Liquid-cooling retrofit: an interface-first RFI
Compare the same system boundary before comparing cooling capacity or price.
OCP separates the technology cooling loop from the facility water system. A retrofit request should identify who supplies and accepts each interface, rather than treating a CDU rating as proof that a complete installation will work.
Editorial procurement questions, not a design specification or compliance assessment. CoolPower Index research (automated, sourced). No named human technical review is claimed.
Questions to include in your request
Boundary
Which cold plates, hoses, quick disconnects, manifolds, CDU and facility connections are included? Provide a responsibility diagram and exclusions.
Comparable duty
State heat duty with fluid, concentration, temperatures, flow and pressure conditions. Which duty remains available during the specified maintenance or failure case?
Fluid and materials
Provide the compatibility evidence, water-quality limits, filtration requirements and responsibility for sampling and fluid changes.
Retrofit delivery
Identify access, isolation, cleaning, leak testing, controls integration, commissioning and rollback requirements for the existing hall.
Acceptance
Supply a proposed acceptance test, alarm matrix, service coverage evidence and dated availability statement. Identify assumptions needing site confirmation.
Compare the responses
Record unanswered questions as unknown. Ask bidders to return the same scope schedule; keep conditional ratings and exclusions alongside every price.
