W-Class Double Row Cold Aisle Micro Modular Data Center

W-Class Double Row Cold Aisle Micro Modular Data Center with Integrated Modular UPS

1. Product Overview

      Our W-Class cold aisle micro modular data center adopts double-row cabinet layout with fully enclosed cold aisle structure. It traps cold air between server racks, optimizes internal airflow organization, boosts overall cooling efficiency and effectively reduces data center PUE value. The matching modular UPS uses H-series server cabinet as its outer enclosure, unifying visual style with IT racks inside the cold aisle micro modular data center, balancing practical power supply performance and consistent aesthetic design for enterprise machine rooms.

      There are two standard capacity specifications for selection: 15-90 model with total capacity 90kW (single power module 15kW, max 6 modules installable) and 25-150 model rated at 175kW (single power module 25kW, max 6 modules installable). Both versions adopt 3-phase 4-wire input and 3-phase 4-wire output architecture.

1.1 Model Differentiation Comparison Table

Only parameters with different values between the two models are listed below, identical specifications are not included:

      For input electrical performance, rated input voltage is 3x380VAC/400VAC/415VAC (3Ph+N). Input voltage tolerance ranges from 305-478VAC under 100% load and 208-304VAC under 70% load. It supports adaptive 50/60Hz frequency within 40-70Hz. Input power factor exceeds 0.99 at full load and remains above 0.98 at 50% load, with THDi kept below 3% at 100% load.

      On the output side, stable three-phase voltage output is realized: steady voltage deviation is ≤±1% for balanced load and ≤±2% for unbalanced load, transient fluctuation is controlled within ≤±5%. Synchronization frequency ranges 46-54Hz or 56-64Hz, battery-mode frequency accuracy reaches ±1% for 50/60Hz. Overload capacity supports 110% load for 60 minutes, 120% for 10 minutes, 150% for 60 seconds and over 150% for 200-millisecond short-time withstand. THDV stays ≤1.5% under linear load and ≤4% under nonlinear load, overall system efficiency can hit above 95%.

      The battery charging system features rated battery voltage ±216V (36 units of 12V cells), max charging voltage ±240V (40 units of 12V cells), cut-off minimum voltage ±192V (32 units of 12V cells), 2.25V per cell float charge voltage and 2.35V per cell boost charge voltage with built-in temperature compensation. Charging current is 6A for 15-90 model and 8A for 25-150 model.

      Both UPS cabinets share dimension of 600×1200×2000mm, net weight is 295kg for 15-90 variant and 355kg for 25-150 variant. Operating environment allows 0-40℃ temperature and 0-95% non-condensing relative humidity, full rated power output available below 1000m altitude with IP20 ingress protection grade.

      Monitoring interfaces include RS-232 and USB, compatible with Windows old & new editions, Linux and MAC OS; optional SNMP module supports remote network power management. The whole product complies with IEC/EN 60950-1, IEC/EN 62040-1 safety standards and IEC/EN 62040-2 Category C3 EMC specifications.

      The cold aisle mechanical structure is fitted with flip skylight with built-in lighting (manual/auto switchable), top-mounted adjustable H-type cable trough with three independent wiring lanes, supporting left-right horizontal cabling and downward cabling. All structural parts are delivered in flat packing for cost saving, assembled on site without hot work, easy leveling to guarantee installation precision of the entire cold aisle micro modular data center.

2. Typical Application Scenarios

   ● Medium and large enterprise core computer rooms

   ● Government provincial/municipal data centers

   ● Financial institution regional data hubs

   ● Industrial park centralized server rooms

   ● Hospital & educational institution data infrastructure

   ● Colocation data center standard containment zones

3. Core Product Advantages

3.1 Optimized Airflow & Low PUE

      Sealed double-row cold aisle concentrates cold airflow around IT equipment, cuts unnecessary cold air dispersion and reduces overall cooling consumption significantly. Integrated skylight lighting reduces extra fixture layout inside the aisle to further optimize space utilization.

3.2 Robust Cabling & Structural Reliability

      Custom H-type cable trunking with adjustable width and triple-slot design accommodates diverse cabling demands. Pre-reserved mounting holes simplify installation and later modification; flexible left-right and down wiring adapts complex on-site cabling routes.

3.3 Convenient Deployment & Intelligent O&M

      Flat packed components lower logistics cost, on-site splicing requires no hot cutting or welding work. Fine leveling design ensures structural precision after installation. Rich communication ports plus SNMP optional upgrade realize centralized remote monitoring for unmanned operation.

3.4 Unified Visual Design

      Modular UPS cabinet shares the same dimension and appearance with server racks, keeping neat and consistent interior layout inside cold aisle containment zones for professional enterprise-grade visual effect.

4. Why Choose W-Class Double Row Cold Aisle Solution

     1.Dual power tier selection: 90kW and 175kW two mainstream power grades cover mid-to-large load demands, modular power unit supports later capacity expansion.

     2.Outstanding power quality index: ultra-low input harmonic, high input power factor and excellent output voltage stability reduce power loss and interference to sensitive IT devices.

     3.Integrated airflow + power design: cold aisle containment and matching modular UPS are developed as one set solution, avoiding mismatching between third-party aisle and power equipment.

     4.Cost-effective on-site construction: no on-site hot work, prefabricated structural parts shorten installation cycle and lower on-site construction risks.

     5.Global standard compliance: fully meets IEC international safety and EMC norms, convenient for cross-border project delivery and third-party certification acceptance.

5. Frequently Asked Questions (FAQ)

Q1: Can I expand UPS power modules after the cold aisle system is put into operation?

A1: Yes. Both models reserve 6 slots for power modules, you can add modular units gradually as IT load grows without replacing the whole UPS cabinet.

Q2: How much PUE improvement can this cold aisle containment bring compared with open rack layout?

A2: Centralized cold air confinement reduces cooling waste obviously, matching high-efficiency modular UPS can deliver notable PUE reduction for long-term operation cost saving.

Q3: Is the skylight lighting controllable both manually and automatically?

A3: The flip skylight integrates lighting function with two control modes: manual switch and automatic induction control for flexible on-site management.

Q4: What is the maximum deployment altitude for rated full power output?

A4: Full rated power is guaranteed below 1000m altitude; derated operation is required for sites higher than 1000m, please confirm altitude data during inquiry.

Q5: Can SNMP remote monitoring function be added as a later upgrade?

A5: SNMP module is optional configuration, you can select it at initial order or purchase it as post-delivery upgrade for network centralized management.
