Liebert EFC Indirect Evaporative Freecooling System, 400kW, Rooftop
Liebert EFC Indirect Evaporative Freecooling System, 400kW, Rooftop features multiple components integrated to optimize cooling performance, efficiency and protection. A high-efficiency, epoxy-coated aluminum heat exchanger is designed for the life of the cooling unit. Its enhanced plate design increases evaporative surface area, providing a total area larger than that of an NFL football field. This innovative heat exchanger provides cooling to within 1 degree of wet bulb temperature, with up to 85% effective heat transfer in dry mode and air leakage of less than 0.1%. It provides an average peak mechanical PUE of less than 1.25, and an operational PUE under 1.10 The system's advanced Liebert iCOM thermal controls feature teamwork algorithms that coordinate the operation of multiple cooling units for maximum efficiency and protection. These controls provide independent management of capacity and temperature to support higher return air temperatures and greater efficiency. Liebert iCOM monitors hundreds of unit and system operating parameters for analysis and protection, and features self-healing control routines that automatically avoid dangerous thresholds. An integrated spray system features a rugged, stainless steel 100-gallon sump that provides temporary ride-through if water flow were interrupted. Dual pumps provide partial capacity in the event of a component failure. A quick-change design simplifies pump replacement. The water spray branches for evaporative cooling, feature quick-change, snap-on nozzles for easy maintenance. A scavenger section contains multiple EC fans that pull outside air through the heat exchanger. A fan removal apparatus simplifies fan removal and maintenance. The unit’s DX trim has varying capacities to match load requirements, utilizing two optional interlaced coils for greater efficiency. An integrated condenser for DX cooling is precharged at the factory. Compressors are designed for easy replacement without cutting piping.
