Vertiv Liebert DSE Precision Cooling Unit
Vertiv Liebert DSE Precision Cooling Unit in Qatar
The Vertiv Liebert DSE is a packaged DX precision cooling system with integrated pumped-refrigerant economization, designed for data centres that want lower energy bills without using water for cooling. When outdoor conditions allow, the system can reduce or stop compressor operation and move heat using a refrigerant pump, while the compressor takes over during hot periods. Vertiv cites operational PUE under 1.2 for this approach. It uses EC fans and the Liebert iCOM controller to optimise operation automatically. In Qatar the economizer hours are mainly during the cooler months, so we model the benefit for your site. AstenAI supplies, installs and supports the Liebert DSE in Doha and nationwide.

Liebert DSE pricing depends on capacity, condenser selection and project scope. Contact us for the latest QAR price, an energy-saving estimate for your site and an installation quotation in Qatar. Our team in Doha can advise on the best configuration for your site.
The pumped refrigerant economizer works when outdoor temperatures are low enough, which in Qatar mainly means winter months and cooler nights. In hot periods the compressor operates normally. We estimate the expected savings using your setpoints and local climate data.
No. Its economization uses a refrigerant pump rather than water or evaporative cooling, which avoids water treatment and consumption. Heat is rejected through an outdoor air-cooled condenser. Our team in Doha can advise on the best configuration for your site.
