  • Provides integrated rack-mounted Environmental Cooling Module (ECM), and a Back-Up Cooling Module (BCM).
  • Secure Door: lockable door provides an extra measure of security.
  • External Dim.: 77"H x 23.5"W x 38"D
  • Internal Rack Dim.: 42U / 73.5" x 19"W x 26.5" to 30.5"D (adjustable depth)
  • ECM Supported Cooling Load: 1647 Watt / 5621 BTUH
  • BCM Supported Cooling Load: 824 Watt / 2811 BTUH
  • Max Ambient Temp: 105°F / 41°C
  • Sound Level (1.5m): 52 Lpa (ECM), 59 Lpa (BCM)
  • Input Power: 120V @ 60Hz
  • Standards: IEC IP52 enclosure (HD/RD systems), NRTL: ETL and CSA approved, ISTA Procedure 1B
  • Warranty: None - 2 Years with optional StartUp Service (contact us)

Includes: Front Plexi Door, Rear Door BCM Assembly and insulated side panels, Rail FRT/RR SQR 42U (78"), EMC2000LR-T60 & BCM2000L-60, Caster Kit, High Temp Alarm, Adapter ECM 19" x 38" Duct, Color RAL 7021.

Please Note: Self-contained racks cannot be returned. Please make sure to size your airflow requirements, and power requirements correctly before ordering. Standard manufacturer warranty still applies. For other rack sizes, 3.6 kW capacity, or other configurations, please contact us.

Top Mounted Environmental Cooling Module

Internal ECM
The integrated ECM enclosure design promotes the best air circulation to prevent hot spots within the enclosure. Inside and outside air are isolated for maximum cleanliness.

Back-Up Cooling Module

Back-Up Cooling
During high internal temperature or power outage conditions, the BCM (Back-Up Cooling Module) — powered by the enclosure’s UPS — is automatically activated, drawing in filtered outside air to ensure continuous air flow to protected equipment.

In-Row Environmental Cooling Module

Air Distribution
Exclusive ECM conditioned air distribution duct ensures uniform air flow for multiple enclosures.


Flexibility:

  • Designed as a plug-and-play system ready to install.
  • Wheel-mounted cabinet for easy relocation.
  • Adjustable racks and rack rails support a wide variety of equipment.
  • Optional top mounted air conditioning allows maximum use of internal rack space or can be used to double cooling capacity with the internal air conditioning unit.

Higher Availability:

  • Cools IT equipment to eliminate downtime from overheating.
  • Lockable door protects against unauthorized access.
  • Specially designed door gasket and sealed cable entrance ensure stable cooling environment.
  • Optional back-up cooling assures continued cooling in the event of a power loss.
  • Improved cable access and management improves airflow to reduce overheating of protected IT equipment.

Lowest Total Cost Of Ownership:

  • Competitively priced as an integrated system, compared to purchasing separate components.
  • Simplified plug-and-play installation reduces overall implementation time, reducing costs.
  • Optional energy saver control saves money by allowing back-up cooling to operate as primary enclosure cooler.
  • Integrated air conditioning reduces potential downtime costs by assuring proper system operation.

Ideally Suited For:

  • Network closets
  • Server closets or small rooms

Power can be supplied and protected through an optional Liebert GXT on-line UPS or Liebert PSI line-interactive UPS. Power distribution is supplied via optional Liebert MPH2 PDUs.
