DATA CENTER CHILLER 500-1450 KW

The Liebert^® AFC adiabatic freecooling chiller combines three key cooling technologies: adiabatic, freecooling and mechanical cooling. This combination of technologies allows the Liebert^® AFC to achieve the highest efficiency levels and guarantee continuous availability even under the most critical conditions.

Liebert^® AFC adiabatic technology is designed to increase freecooling capacity and extend freecooling operation at temperatures up to 30-32°. Furthermore, full operation of the back up compressors is guaranteed up to 50°C, thus ensuring continuous cooling availability also at extreme ambient temperatures.

Featuring Fast Start Ramp, Liebert AFC also ensures that capacity is fully restored in 70 seconds following a power restart, thus guaranteeing the unit’s immediate activation. The control, further, continues operating without the need of an external single phase power supply.

Features:

• ​Integrated Adiabatic System – Highly efficient adiabatic wet pads humidify air entering the freecooling and condensing coils, thus increasing the freecooling chiller system operation and mechanical efficiency.
• Supersaver – The Supersaver is the software logic embedded in the iCOM Control leveraging on the communication with floor mount units to maximize efficiency at system level.
• Fast Start Ramp – Fast recovery capacity: the unit ensures the re-establishment of the full cooling capacity in 70 seconds, following a power restart. The control remains operative without the need of an external single phase power supply.
• New iCOM^® 7’’ Touch Display  – The iCOM Control ensures the intelligent management of units within the dynamic data center environment, while the innovative 7” touch screen display presents advanced graphic functions.
• New Generation EC Fans – the new generation super silent EC fans dramatically reduce the noise levels and increase the overall unit efficiency.
• Electronic Expansion Valve – Minimizes condensing pressure to reduce compressors’ power consumption thus achieving high efficiency levels.
• Microchannel Condensing Coil – The full aluminum fan coil ensures extreme efficiency levels during the mechanical cooling mode and minimizes the refrigerant charge.

Benefits:

• Significant annual efficiency levels deliver a pPUE of 1.08
• Grants continuous cooling availability in case of water shortages, extreme ambient temperatures and unstable power supply
• Optimizes efficiency levels of data center applications including Liebert PCW and Smart Aisle Containment.

CHILLERS WITH 700-1600 KW COOLING CAPACITY

The Liebert HPC freecooling chiller is the ultimate chilled water-based solution delivering high efficiency and reliability. Its freecooling and compressor functioning options make it ideal for data center applications with cooling needs ranging from 350 kW to above 20 MW. Three different sound emission versions offer the possibility to choose standard or unrivalled low noise levels.

The built-in freecooling section together with the “Supersaver” system, guarantee the complete integration with indoor air conditioning units and allow significant energy savings, while increasing the system’s lifetime and reliability.

The unit’s maximum efficiency is reached through the leveraging of its free cooling capability and the embedded iCOM^® control function, which ensures the efficient management of system load sharing, further maximizing performance.

Features:

Freecooling

Integrated freecooling system to enhance energy savings and increase reliability.

Fast Start Ramp

Fast Start Ramp is the innovative technology which ensures immediate restoration of chiller operation following a power restart. This reliable technology allows the activation sequence to begin 20 seconds after power restoration, ensuring water temperatures remain stable.

iCOM^® Control

The iCOM software has been developed by Emerson Network Power to specifically ensure the intelligent control of the units within the dynamic data center environment.

Screw Compressors

Excellent performance is ensured both at full and partial load as a result of the continuous capacity control system integrated within the control logic.

EC Fans

High efficiency EC motors guarantee a 25% saving in energy consumption compared to traditional AC motors. EC fans are further optimized for operation, eliminating electromagnetic-related noise and minimizing overall sound emission.

Supersaver

This unique functioning mode may be set up in combination with the Liebert® PCW in order to additionally enhance energy savings.  This function allows the floor mount units to communicate via LAN with the freecooling chiller, automatically increasing water temperature when the thermal load decreases. This in turn enhances the system’s seasonal efficiency and freecooling operating time.

Benefits:

100% Cooling Availability

• Advanced iCOM^® Control logic and components aimed at guaranteeing maximum availability
• Fast start ramp ensures immediate restoration of chiller operation
• Enhanced management of availability and redundancy as a result of the flexible iCOM teamwork logics

Extremely Low Operating Costs

• Significant freecooling capacity results in the reduction of compressors’ working hours
• Maximized efficiency as a result of state-of-the-art technologies such as EC Fans and Electronic Expansion Valve
• Further minimization of the total cooling system energy consumption allowed by the iCOM teamwork working logics

Extremely Low Noise

• Innovative EC Fans and special acoustic insulations guarantee the greatest comfort. Three noise level versions available.
