Context
A national public-sector organization required a high-availability data center that could be built faster than a stationary facility while meeting strict reliability and energy-efficiency standards. The site had limited construction options and a fixed power envelope. The customer needed a turnkey, factory-tested solution that could be transported, assembled, and fully commissioned outdoors under all-weather conditions.

Factory build and site commissioning within months
IT capacity
Up to 16 racks / 120 kW IT load
Challenges
— Time-to-value
Deliver Tier III-equivalent resilience within months, not years
— Energy efficiency
Integrate direct free-cooling to reduce operating costs
— Environmental limits
Outdoor installation, minimal site works
— Operational continuity
Maintain redundancy across cooling, power, and safety systems
— Mobility
Design the complex to be disassembled and re-assembled if needed
Solution
A two-module 40-ft ISO-based MDC complex joined along its long side, creating unified IT and MEP zones. The system combines direct free-cooling with precision air-conditioning and intelligent humidity control.
Each module was factory-built and fully tested (FAT), then shipped and installed at the customer site for SAT and commissioning. The MDC operates as a stationary facility but remains relocatable for future moves.

FAQ
What is a modular data center?
A modular data center (MDC) is a prefabricated, container-based data center that integrates racks, power, cooling, and security systems inside portable enclosures. Unlike traditional on-site construction, a containerized modular data center is factory-built, tested, and shipped ready for installation. ModulEdge designs scalable modular data centers from 5–50 kW per rack with DX, chilled-water, adiabatic, and free-cooling options — engineered for edge and AI workloads where reliability and low latency matter most.
Why consider a modular data center?
A container modular data center enables faster deployment, lower risk, and predictable performance compared to conventional builds. Prefabricated and tested in the factory, these systems minimize site work and allow operators to scale step-by-step as demand grows. Organizations in telecom, industry, energy, and defense choose mobile and containerized data centers to place compute closer to operations, improve resilience, and maintain on-prem control of sensitive workloads. ModulEdge’s portable modular data center solutions combine EU engineering with ruggedized designs for harsh conditions.
How are modular data centers different from traditional data centers?
Traditional data centers are built on-site, requiring long construction cycles and multiple contractors. A prefabricated modular data center is built in controlled factory conditions, integrating power, cooling, fire suppression, and monitoring systems before shipment. This approach cuts deployment from years to months, ensures quality through FAT/SAT testing, and allows redeployment when operations move. ModulEdge’s containerized data center infrastructure offers the same Tier III/IV design principles as conventional facilities — with faster rollout, lower cost, and modular scalability.
Are you Tier III certified?
Our modules are designed to meet Tier I - IV principles. Certification applies to a specific site and build; we support auditor engagement for deployments that pursue certification.
Do you support AI training clusters?
No. We position for edge AI inference at ≥40 kW per rack. Training‑class densities (≈120–150 kW/rack) are not feasible in this form factor.
What’s the typical lead time?
Custom builds: 3–6 months. Commissioning depends on scope and site readiness (power, pad, network). We’ll confirm a schedule during design review.
How do you handle hot or variable climates?
We match DX, chilled‑water, adiabatic, or free‑cooling to your climate and energy costs, targeting predictable efficiency (modeled PUE) and thermal headroom.
Can the modules handle harsh environments?
Yes – dust/sand/humidity hardening, vibration tolerance, and optional EMP shielding are available to maintain uptime in demanding sites.
Will this integrate with our existing monitoring and access control?
Yes. We deliver integrated monitoring and access/CCTV and align interfaces during design review to fit your tooling and security policies.
Can we redeploy modules later?
Yes. Standard 20‑ft and 40‑ft footprints with a redeployable approach; we provide rigging/placement plans and support relocation.
Do you sell direct or via partners?
We’re partner‑first (OEM/whitelabel and system integrators). End‑user projects are delivered with or through partners.
