EVPACO Specification Sheet.pdf

This document is a product specification and design features manual for Evapco's ATW (Closed) Cooling Tower, detailing its operational principles, technical specifications, and optional equipment. The principle of operation involves circulating process fluid through a closed circuit cooler, where heat is dissipated through the coil tubes, and simultaneously drawing air through the air inlet to cool the water. Key design features include the patented Thermal-Pak® coil, which provides greater operating efficiency with lower thermal resistance and higher water loading capabilities.

The document outlines several optional equipment enhancements, such as sloped access ladders for safe component access, working platforms with ladders and davits for servicing fan motors, stainless steel water touch basins for corrosion protection, and basin level platforms to facilitate maintenance. The cooling towers are constructed using high-quality steel tubing, with each circuit pneumatically tested at 400 psig and the entire assembly dip-galvanized for corrosion resistance. A critical note emphasizes that these closed circuit cookers should only be used on sealed, pressurized systems, as continuous aeration in an open system can cause tube corrosion and premature failure.
