LIEBERT FL4039 | 396 kW Air-Cooled Chiller | Screw | R134a | Dual-Circuit | Freecooling | 2018

In this video, we take a closer look at the LIEBERT FL4039 — a high-capacity air-cooled chiller built for energy-efficient chilled-water production in large commercial and industrial HVAC applications. Running on R134a with two Bitzer screw compressors and two independent refrigerant circuits, it delivers stable performance and solid redundancy across varying load conditions. A plate heat exchanger ensures effective thermal transfer, while 8 EC-fans provide quiet, energy-optimized condenser airflow. The integrated freecooling module enables significant energy savings during cooler periods. The hydraulic module features three dedicated Grundfos pumps — two for chilled water and one for the freecooling circuit — plus an expansion vessel, for a fully self-contained solution. Good condition with documented operating hours, ready for commissioning. 🔧 Key specifications: • Cooling capacity: 396.0 kW / 112.6 tons (15/10 — 35 °C) • Year of manufacture: 2018 • Condition: Good (Working hours: 862 / 3,889 h) • Refrigerant: R134a • Refrigerant circuits: 2 • Compressors: 2 × Bitzer CSH7573-70Y40D (screw) • Heat exchanger: Plate • Condenser: Copper / Aluminum • Fans: 8 pcs. (EC-fans) • Hydraulic module: 1 × Grundfos NB65-125/120-110 X-E-A GQQE + 1 × Grundfos NB65-125/120-110 X-E2-A-BQQE + 1 × Grundfos NB65-125/137-X-F-A-GQQE (Freecooling), expansion vessel • Options: Freecooling • Dimensions: 5.1 × 2.31 × 2.6 m • Weight: 5,142 kg Ideal for data centers, large commercial buildings, and industrial process cooling where dual-circuit screw compressor reliability, integrated freecooling, EC-fan efficiency, and a fully integrated hydraulic module deliver maximum performance and energy savings. 📩 Looking for a proven Liebert air-cooled chiller?
