Liebert

Liebert is a precision cooling and power management brand now part of Vertiv, formerly Emerson Network Power. Liebert produces precision air conditioning systems, UPS, power distribution, and infrastructure monitoring for data centers and critical equipment environments. Liebert systems maintain tight temperature and humidity tolerances at a high sensible heat ratio designed for electronics cooling rather than human comfort.

Liebert Product Lines

• Liebert DS: Direct expansion precision cooling in downflow and upflow configurations for raised floor and open-floor data centers.
• Liebert PCW: Process-cooled water precision cooling for chilled water infrastructure.
• Liebert Mini-Mate: Compact precision cooling for small server rooms and network closets.
• Liebert GXT UPS: Uninterruptible power supplies for critical equipment protection.
• Liebert MPX Row Cooling: Row-based cooling adjacent to server racks for high-density environments.
• Infrastructure Monitoring: Real-time temperature, humidity, and power monitoring platforms.

Why Contractors Specify Liebert

Liebert precision cooling is designed for the high sensible heat loads of electronic equipment rooms with sensible heat ratios above 0.95, continuous 24-hour mission-critical operation, and upflow and downflow configurations for raised floor and open-floor data center environments.

How to Choose a Liebert Product

Determine the equipment heat load in kW and the floor area. Use Liebert DS for general server room applications, Liebert MPX row cooling for high-density racks, and Liebert Mini-Mate for small closets and network rooms. Specify the condenser type based on available facility infrastructure.

Frequently Asked Questions

• Precision vs. comfort cooling? Precision has high sensible heat ratio for electronics; comfort cooling balances sensible and latent for occupants.
• Who makes Liebert? Vertiv, formerly Emerson Network Power.
• Can it replace a split system in a server room? No, precision and comfort cooling have different control and airflow designs.
• Mini-Mate application? Small server rooms and network closets where full-size units are oversized.
• Remote monitoring? Yes, via Vertiv infrastructure monitoring platforms.
