DESIGN AND CONSTRUCTION FEATURES<br />
The new ESWA closed circuit cooler is another exciting product from <strong>EVAPCO</strong>. The ESWA is a new high performance<br />
version of the original ESW with greater capacity, more models and increased energy savings! The new ESWA is able to<br />
provide higher performance as a result of our new Sensi-Coil Technology, a new coil design that provides significant<br />
performance improvements on every ESWA model.<br />
Sensi-Coil Technology features over 20% more Thermal-Pak ® elliptical tubes packed densely together into the same coil<br />
plan area as the original ESW. This design also has 50% more water loading than the previous ESW line. More surface<br />
area plus more water equals higher capacity resulting in more performance with the ESWA in a smaller footprint with<br />
less energy.<br />

Technology<br />
The NEW Sensi-Coil , exclusive on the new ESWA closed circuit cooler, features the<br />
maximum amount of Thermal-Pak elliptical tubes packed densely together in a new<br />
coil arrangement.<br />
The new Sensi-Coil transfers heat through its tube walls<br />
in a sensible exchange - No air travels through the tube<br />
bundle, therefore tighter tube spacing is possible. Look at<br />
the side by side tube spacing comparison below.<br />

Sensi-Coil <br />
Original Thermal-Pak Coil<br />
used in the ESW<br />
The Sensi-Coil Features:<br />
• More Thermal-Pak ® elliptical tubes densely packed together<br />
into the same plan area used on the original ESW.<br />
• Over 20% more coil surface area than the original ESW coil.<br />
• Higher water loading capability for more heat rejection,<br />
increasing from 8 l/s per m 2 to 12 l/s per m 2 , a 50% increase!<br />
• More surface area and more water equals higher capacity<br />
and increased energy efficiency.<br />
This innovative tight tube spacing is designed specifically to<br />
maximize sensible heat transfer, and is exclusive on the<br />
ESWA product line.<br />
