Eco-ATWB Closed Circuit Cooler

Eco-ATWB Closed Circuit Cooler has an Innovative design with axial fan for any application. Suitable for outdoor applications, where energy and water savings are a priority. Ideal for dense placement of energy efficient equipment and projects.


The eco-ATWB line of closed circuit coolers has been specifically designed to dramatically increase both the evaporative (latent) and dry (sensible) modes of cooling. With this revolutionary design, the EVAPCO eco-ATWB will also save water and energy by increasing the unit’s efficiency in both the evaporative and dry cooling modes of operation. The eco-ATWB utilizes the EVAPCO Ellipti–fin® coil which features elliptical spiral fin technology to maximize the surface area available for heat transfer. The Ellipti–fin® coil now features

Internal Tube Enhancement which increases the internal heat transfer coefficient of the coil and thus increases the cooling capacity of the unit. The eco-ATWB is the ideal solution for: reducing water consumption, lowering energy costs, increasing the dry-bulb switchover temperature, and maintaining super low sound levels. This product is designed with IBC Compliant construction and CTI Certified Performance.

  • Highest ambient dry bulb switchover temperature in the industry
  • Dry coil piped in series with evaporative coil to dramatically reduce water consumption, ALWAYS, even in evaporative mode
  • Plume reduction in evaporative mode, plume elimination in dry mode
  • Ranging in capacity from 1,046 - 20,076 MBH
  • IBC Compliant – Independently certified to withstand seismic and wind load forces at ALL building locations in North America
  • Independently certified by the Cooling Technology Institute
  • The increased surface of the coil exchanger, made using EVAPCO's patented EVAPCO Ellipti-fin® technology with improved CROSSCOOL ™ pipes, made in the form of an ellipse with internal grooves, increases the performance of the cooler and provides the ability to work in wet and dry conditions.
  • Comes with intelligent control system for maximum water saving and energy saving.
  • CTI-certified, compatible with IBC and ASHRAE 90.1.
