Trust, but Verify.
Data Centre Commissioning & DLC Expertise
Quantum MC provides data centre commissioning, Direct Liquid Cooling expertise and independent technical assurance across Europe and the UK. We support and verify the full Levels 0-6 commissioning lifecycle, translating design intent into measurable acceptance criteria and the evidence required for operational handover.
Full Lifecycle: Levels 0-6
Commissioning strategy, design review, factory testing, installation verification, start-up, functional testing, IST and operational handover.
Independent Technical Oversight
Client-side Commissioning Authority (CxA) and contractor support, with defined responsibilities, witness points and traceable test evidence.
Commissionability by Design
Review test access, isolation, instrumentation and sequences of operation before installation constraints become testing delays.
Direct Liquid Cooling Expertise
Industry-recognised experts in commissioning DLC designs: facility water, CDUs, technology cooling loops and their control interfaces.
Performance Under Test
Verify capacity, control response, alarms and agreed failure scenarios against project-specific acceptance criteria.
Evidence for Handover
Track deficiencies, witness corrective work and assemble test records, training evidence and operational documentation.

FAQ
Data Centre Commissioning FAQs
Commissioning scope, Levels 0-6, installation quality and Direct Liquid Cooling: the questions that shape a testable, coordinated project.
What does QMC verify during commissioning?
We verify that electrical, mechanical and control systems meet the agreed design intent and acceptance criteria. This covers installation readiness, individual-system performance and integrated operation, supported by recorded test results and deficiency close-out.
When should commissioning begin?
During project definition and design. Early commissioning input establishes scope, responsibilities and acceptance criteria, and identifies the access, isolation, instrumentation and control provisions needed to test the completed installation.
How do QA/QC and commissioning work together?
QA/QC checks the installation against approved documents and manufacturers’ requirements. Commissioning then demonstrates functional and integrated performance. Coordinating both disciplines makes readiness evidence and outstanding defects visible before each test stage.
Does QMC support the full Levels 0–6 lifecycle?
Yes. QMC provides full commissioning lifecycle support and verification across Levels 0-6, from commissioning strategy and design review through factory testing, installation verification, start-up, functional performance testing, integrated systems testing and operational handover.
Level definitions, hold points and responsibilities are agreed in the project commissioning plan. At each stage, we establish what must be demonstrated, what evidence is required and which actions must be closed before progression.
How does QMC commission Direct Liquid Cooling?
QMC are industry-recognised experts in the commissioning of Direct Liquid Cooling designs for data centres. We verify the interfaces between facility water, coolant distribution units (CDUs), the technology cooling loop and controls. The agreed test scope covers flow, differential pressure, temperatures, thermal response, alarms, leak detection and failure response, with coolant-quality and handover evidence.
What does integrated systems testing demonstrate?
IST demonstrates how power, cooling and controls work together under specified operating and failure scenarios. Tests verify sequences, redundancy, alarms and recovery against the approved test scripts. Recorded results and unresolved deficiencies inform the handover decision.
