Liebert Mini Computer Room Enclosure

The Liebert MCR (Mini-Computer Room) is a self-contained rack enclosure system that includes a load-sized, computer-grade air conditioner located at the bottom of the enclosure, with the option of a top mount design, supplying cool air to sensitive equipment on all levels. A back-up cooling system ensures environmental security. Power can be supplied and protected through an optional Liebert GXT on-line UPS or Liebert PSI line-interactive UPS.

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.
  • Back-up cooling assures continued cooling in the event of a powerloss.
  • 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

42U’s Vision is to inspire corporate responsibility in energy efficiency and be a leader in providing technology and vendor agnostic information, suggestions, and solutions for making data centers more energy efficient.

External ECM

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.

Air Distribution

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.

Back-Up Cooling

Air Distribution

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

Internal ECM

External ECM

The top mounted ECM allows maximum use of internal rack space or can be used with the internal/rack mount ECM to double cooling capacity.
