    MISSION-CRITICAL UPTIME

    DataCenters

    Five nines is the entry fee, not the target. We engineer the layer between the utility and your white space: the one that decides whether a grid event becomes an incident.

    The rack is protected. The chiller is not.

    Distributed rack-level UPS is now standard, and it does its job. What it does not do is protect the mechanical plant (chillers, CRAC units, pumps, controls) that determines how long the IT load survives after a supply event. A facility can lose cooling and stay powered, and it will still go down; it just takes longer and does more damage.

    Centralized protection at the service entrance closes that gap. A medium-voltage UPS sitting on the 5–25 kV intake protects everything downstream, including the plant that keeps the room within temperature. At 2.25 to 22.5 MW, that is whole-hall or whole-campus coverage from one asset rather than dozens.

    Power quality is the second half of the problem. Data centers run large non-linear loads and pay for reactive power on intake tariffs where electricity is typically around half of total operating cost. Automatically switched compensation at the intake substation delivers fine-grained group correction from a small footprint, and pays for itself against the tariff rather than against a downtime risk model.

    THE PROBLEM

    What actually causes the incident

    • Mechanical plant left unprotected

      IT load rides through on rack UPS while cooling drops. Thermal runaway follows within minutes in a high-density hall, and the recovery is far worse than a clean shutdown.

    • Utility events below outage threshold

      Voltage sags too short to register as an outage still trip variable speed drives on chillers and pumps. The utility record shows a clean supply; the site shows a load loss.

    • Reactive power on the intake tariff

      At half of operating cost, electricity charges dominate. Poor power factor at a 110/220 kV intake substation converts directly into penalty charges that no amount of PUE tuning recovers.

    • Harmonic distortion from non-linear load

      Rectifier front ends across thousands of power supplies distort the supply waveform, heating transformers and neutrals and eroding the margin that was designed in.

    • No space for the solution

      By the time a power quality problem is understood, the electrical rooms are full. Outdoor-rated containerized systems are frequently the only deployable answer.

    • Commissioning risk at energization

      New capacity is energized against a schedule that has already slipped. Without disciplined FAT and SAT, latent defects are discovered by production load.

    TRACK RECORD

    Work we have done here.

    • Containerized UPS lineups delivered and commissioned for US technology and colocation sites
    • Container lift-and-set installations completed on live campuses without shutting down adjacent load
    • Legacy PureWave UPS fleets kept in service with spares, refurbishment and scheduled maintenance
    • Intake-level power factor correction engineered against published tariff penalty thresholds
    COMMON QUESTIONS

    Questions from this sector.

    Why medium-voltage UPS instead of more LV units?
    Because the protection boundary moves. An MV UPS on the 5–25 kV intake protects everything downstream, mechanical plant included, from one asset, and avoids the conversion losses and floor space of stepping the whole load down first. Below a few megawatts, LV modular is usually the better economics; above it, MV wins.
    Can you deploy without taking the site down?
    In most cases yes. Containerized systems are factory-tested, craned into position and tied in during a planned window. We plan the switching sequence and the fallback with your operations team before anything is energized.
    Do you work to our change control process?
    Yes. Maintenance and commissioning work in live data centers is scheduled inside your change windows, with method statements and risk assessments issued in advance for approval.
