The Most Advanced Refrigerant Economiser

The Liebert PDX with EconoPhase is configured like a conventional direct expansion (DX) air-cooled system, but with the incorporation of a refrigerant pumping module on the liquid line. This facilitates the transition to a more economical mode of operation when the external temperature is lower than the internal temperature of the facility. The Liebert PDX with EconoPhase provides up to 50 percent energy savings compared with the most efficient air-cooled DX models. It is capable of achieving partial Power Usage Effectiveness (pPUE) levels down to 1.05, equating to an annual energy cost reduction of up to £170,000 when compared to a typical 1 MW data centre with a pPUE at 1.3. This equates to a CO2 saving of 1,150 tonnes.
