Description
The Liebert® CW system integrates cutting-edge coil, valve, and control technologies to ensure maximum protection and efficiency. With units available in 440kW capacities, it significantly lowers deployment and maintenance costs while enhancing energy efficiency. This is achieved through an optimized chilled water coil design that can utilize higher entering water temperatures (EWT). The system offers multiple connection options, providing greater flexibility during installation and commissioning. Additionally, right and left side access for supply and return piping connections minimizes floor space usage by allowing units to be placed closer together.
