EVAPCO ESW4 Closed Circuit Cooler

Large single-cell closed circuit cooler combining high capacity with optimized energy efficiency.

Rating: 5.0 / 5

ESW4 is designed to maximize capacity and optimize energy efficiency in a large single cell. More than 130 models support data centers, industrial plants and major HVAC applications. The Sensi-Coil® elliptical coil with CrossCool™ internal tube enhancement provides high capacity in a compact footprint with reduced connected fan power.

The closed circuit separates the process fluid from spray water and ambient air. This limits contamination of the process loop, simplifies fluid-quality control and supports data-center, industrial, power-generation and major-building cooling systems.

  • Closed circuit protects the process fluid from contamination.
  • High evaporative heat-rejection efficiency.
  • Broad capacity range and construction options.
  • Suitable for industrial facilities and data centers.
  • Corrosion-resistant and low-sound options are available.
  • Induced-draft axial-fan arrangement
  • Capacity range: 270–670 nominal tons per cell.
  • Closed heat-exchange circuit.
  • Evaporative cooling with recirculating spray water.
  • EVAPCO equipment for year-round operation.
