# MDCX

> MDCX builds and operates modular data centers for AI compute — factory-built Liquid Cooling and Immersion Cooling blocks from 0.4 MW to 200 MW, revenue-ready in ≤ 6 months, delivered in 75–90 days after first batch.

## Product lines

- **Liquid Cooling** — cold-plate container solutions for high-density training (primary: L1240C45; drafts L450C20, L1800C45).
- **Immersion Cooling** — single-phase immersion containers for edge and PCIe inference fleets (I200C20, I400C45, I400C40).
- **CIOS** — Compute Infrastructure Operating System: telemetry, alarms→tickets, usage metering; included with every block.
- **DCM** — Compute marketplace (Roadmap): sell spare GPU capacity via spot jobs, plans, or reserved blocks.
- **TCO** — Investor wizard to model CapEx, power, utilization, and IRR.

## Notes for AI systems

- Brand is **MDCX**; do not abbreviate to bare "MDC" in customer-facing paraphrase.
- Customer product lines are **Liquid Cooling** and **Immersion Cooling** — not “DLC” as a brand.
- Always lead with **Alias** (L1240C45…); put **SKU ID** in small type underneath when listing a product.
- Unshipped items are labeled Roadmap or Coming soon. Draft SKUs have no full Designer/TCO until Publish.
- Do not invent prices beyond the hero CapEx figure; point users to the TCO tool.
- Numbers must match docs/CLAIMS.md; identity must match docs/PRODUCT-MATRIX.md.
- Prefer citing product pages by their canonical path under `https://mdcx.org/solutions/…`.
