Specifications

The Liebert CW system combines the latest innovations in coil, valve and controls technologies for optimal protection and efficiency. Units in 340kW and 440kW capacities significantly reduce the cost of deployment and maintenance and improve energy efficiency through an optimized chilled water coil design that can utilize higher entering water temperature (EWT). Multiple connection options provide greater flexibility during installation and commissioning. Right side and left side access for supply and return piping connections reduce the amount of floor space used, by enabling units to be situated closer together.
