( Brand: Liebert ), ( Model: DE240GUAAEI )
The DE240GUAAEI 20 Liebert Glycol CRAC (Computer Room Air Conditioning) unit, manufactured in 2006, is a reliable and efficient cooling solution designed for data centers and other critical environments that require precise temperature control and fortified protection against power failures or other disruptions.
This CRAC unit is a part of Liebert's renowned series of glycol-based cooling systems, which utilizes a propylene glycol solution instead of water as the primary coolant. The primary advantage of glycol cooling is its ability to provide uninterrupted cooling even in temperatures as low as -20 F (-29 C). This makes the DE240GUAAEI an excellent choice for applications where maintaining consistent temperatures is crucial, such as mission-critical data centers or laboratories.
Made of high-quality materials, this Liebert CRAC unit comes with a hot-dip galvanized, 24-inch exterior cabinet and a rigid, one-piece aluminum fin coil to ensure superior durability and corrosion resistance. The 20-ton capacity (72,000 BTU/hour) of the DE240GUAAEI allows it to cool large spaces efficiently while maintaining a low noise output, thanks to its two-speed fan that runs at a low-speed 43 decibels and stabilizes at a standard 52 decibels when in full operation.
Additionally, this CRAC unit features a factory-installed, redundant microprocessor controller that offers a user-friendly interface, constant room temperature, and precise humidity control. It also features multiple built-in fault detection and management functions, including compressor and fan failure alarms, and monitors various critical parameters such as temperature, humidity, and flow rates.
Compatible with both 208/230V and 460V electrical power sources, the DE240GUAAEI can adapt to various power requirements within data centers or critical environments. Furthermore, it includes an optional EPA-rated filter kit, TECA filters that can remove particulate matter up to 0.3 microns in size, and non-ozone-depleting R-134a refrigerant for enhanced environmental performance.
In summary, the DE240GUAAEI 20 Liebert Glycol CRAC unit is a high-performance, glycol-based cooling solution engineered for optimum reliability, precise temperature control, and corrosion-resistant design. Its 20-ton cooling capacity, sound efficiency, redundant microprocessor controller, easy-to-use interface, and flexibility in terms of power sources make it an ideal and sought-after choice for critical applications.
The Liebert DSE 240GUA is a glycol cooling unit, model number DE240GUA, which was produced in the year 2006. It's essential to weigh the pros and cons before purchasing an older model like this to make an informed decision.
