Featuring the Ellipti-fin spirally finned coil and CROSSCOOL internal tube enhancement, eco-LSWE and eco-LRWB are the most energy- and water-efficient forced-draft coolers on the market. Ideal for indoor applications, confined layouts, low height, and low-sound requirements, both models can replace existing forced-draft equipment of the same box size and fan-motor horsepower and provide up to an additional 30 percent in evaporative thermal capacity.
