Leasing a Korean data center? Define the liquid-cooling handover.
Before comparing offers, ask where the facility’s delivery ends and the tenant’s work begins.
Facility: What is delivered?
Interface: Who tests the connection?
Customer equipment: Who operates and maintains?
A specification is also a coordination task
An international tenant can receive a technically detailed proposal and still lack an answer to a practical question: who will deliver a working connection to the equipment? A cooling capability described at building level does not, by itself, explain the scope of the tenant’s installation.
For a Korean deployment, we recommend putting that question into one shared document before procurement dates harden. The local facility team, the tenant’s engineers and the equipment supplier should work from the same equipment list, interface drawing and revision date. These are MGNT’s proposed review steps, not universal contract terms.
Korean cases: a build-out plan and a test are different evidence
Samsong — announced infrastructure build-out. On 26 August 2026, LG CNS announced cooperation with NAVER Cloud to apply direct-to-chip (DTC) liquid cooling at Samsong. The release set completion of construction and demonstration for 2027. This establishes a disclosed implementation plan, not completed acceptance or immediate tenant availability. Ask for the delivery milestone, equipment interface and acceptance evidence for the specific space being offered.
Incheon — an earlier immersion-cooling test. In its 18 April 2024 article, SK Telecom described testing immersion cooling at its Incheon office. This historical example concerns servers immersed in a special cooling fluid; it is not the same configuration as DTC cooling. It supports asking what equipment and operating conditions were tested, but does not establish today's commercial capacity or a tenant's contractual handover.
These public examples illustrate different stages and cooling methods. Neither source discloses the tenant-level allocation of maintenance, incident response or acceptance duties. MGNT's recommendation is to obtain those documents separately. The examples are not MGNT mandates or evidence of MGNT project performance.
Compare the scope, then compare the offer
Ask each shortlisted operator to annotate the same scope sheet. Mark who supplies each component, who installs and tests it, and which party maintains it after acceptance. Separate confirmed inclusions, exclusions and unresolved items. An unresolved item should have an owner and an evidence request, rather than an assumed answer.
Use the scope sheet to distinguish an included facility service from a tenant purchase or a separately priced option. A low headline fee is difficult to interpret when proposals describe different work. The aim is a comparable decision, not a claim that one delivery model is always better.
Make the acceptance discussion concrete
Define: Drawing and equipment scope.
Verify: Test and evidence owner.
Accept: Sign-off and incident contact.
Review question | Evidence to request | Decision to record |
Where is the handover? | Marked drawing and equipment list | Included and excluded scope |
How is compatibility demonstrated? | Agreed test plan and recorded results | Acceptance criteria and signatories |
What happens after an alarm? | Operating procedure and contact chain | First response and escalation owner |
Acceptance should be discussed with the specialists who will carry it out. Ask them to specify the conditions for testing, the records to retain and the treatment of an unresolved result. Do not substitute a generic checklist for equipment-specific engineering requirements.
For cross-border teams, we also recommend a short bilingual issue register. Keep the technical term, drawing reference, responsible party and decision date together. When a revision changes a connection or an operating obligation, flag its effect on procurement and move-in planning before treating the earlier approval as current.
One next step before committing the deployment
Hold a joint scope review with the operator and equipment supplier. Leave with one marked drawing and one open-issues list that every party can identify by version. This does not guarantee deployment success; it gives the next decision a traceable basis.
MGNT Partners is an advisory and project management firm. We begin with the tenant’s deployment objectives and management’s concerns, then help organize local information, compare delivery scopes and coordinate unresolved issues among the relevant specialists.
