The ATWB Closed Circuit Cooler is an Advanced Technology, induced draft counterflow design closed circuit cooler featuring
EVAPCO’s patented THERMAL-PAK® COIL – the most efficient in the industry. The counterflow design provides the
ATWB Closed Circuit Cooler with inherently better operational and maintenance features.

The International Building Code requires that evaporative cooling equipment must meet the
same seismic or wind load forces as the building to which they are attached.
How does it apply?
Based on project zip code and site design factors, calculations are made to determine the
equivalent seismic "g force" and wind load on the unit.
What does EVAPCO offer?
Standard Structural Design
• Projects with ≤ 1.0g seismic or 145 psf wind loads
Upgraded Structural Design
• Projects with > 1.0g seismic or 145 psf wind loads
The upgraded structural design package for the New ATWB is designed for 5.12g and
145psf, making it applicable to ALL building locations in North America.
