Vertiv™ Liebert® EFC low-GWP is the next generation of indirect evaporative cooling.

Vertiv has announced the launch of a new model of indirect evaporative cooling - Vertiv™ Liebert® EFC low-GWP.

Vertiv™ Liebert® EFC with low-GWP refrigerant is an indirect evaporative cooling system with a capacity of 100 to 450 kW for cooling data center equipment. It combines indirect air-to-air and evaporative cooling capabilities in a single unit.

Key benefits:

- A new approach to meet sustainability goals: a new generation heat exchanger with reduced pressure drop ensures lower energy consumption. The heat exchanger is made of a polymeric material that combines high strength and extreme corrosion resistance and optimizes water efficiency.

- Dual mode flexibility: a fast mode switching function that allows the unit to adapt its operation based on specific conditions, switching between a humid priority mode and a direct expansion (DX) priority mode, in order to maximize efficiency and reduce water consumption.

- Cooling with the future in mind: To reduce energy consumption and CO 2 e emissions, the Vertiv™ Liebert® EFC low-GWP is equipped with inverter compressors with refrigerant (R-454B).

- Updated control system: The updated Vertiv™ Liebert® iCOM™ controllers smoothly manage automatic transitions between the most appropriate operating modes, reducing water consumption. Liebert® iCOM™ Control provides high-level control of the units to work together as a single system, thus optimizing room temperature and airflow.

- Innovative design: minimizing electrical infrastructure requirements through free cooling and patented system-level control functions

- Easy installation: providing flexibility and adaptation to a variety of building structures.

Vertiv™ Liebert® EFC is equipped with the most advanced industry technologies including: a new composite heat exchanger, inverter technology with low refrigerant (R-454B), multi-stage evaporation system, new control logic. As a result, the new indirect evaporative free cooling provides even greater efficiency and compliance with technical standards around the world.

Vertiv Avocent MergePoint Unity 2: KVM switch for secure remote access in IT infrastructure management

In distributed IT environments with central data centers, edge locations, branches, and remote servers, it is critical to ensure rapid response to incidents and minimize physical visits to sites. This is especially true for operations performed at the pre-boot stage or when in-band management is unavailable. For such scenarios, Vertiv has expanded its portfolio of remote management solutions with the introduction of Avocent MergePoint Unity 2 (MPU2) KVM switches for secure out-of-band access in enterprise and edge data centers.

AI load in data centers: new aspects of uninterruptible power supply system development

The introduction of artificial intelligence (AI) algorithms significantly changes the energy consumption profile in data centers. Unlike traditional computing processes, AI loads are characterized by high amplitude transients (instantaneous jumps in electrical current parameters): energy consumption can vary from 10% to 130% in milliseconds. Such impulse loads pose risks to the frequency stability and thermal state of power electronics.
