EPAC DIRECT EVAPORATIVE COOLING

The EPAC (engineered packaged adiabatic cooling) direct evaporative cooling (DEC) unit is for commercial and industrial applications where it is engineered to provide cool, fresh, conditioned air for your facility and create a more comfortable and productive work environment while using up to 70% less energy than conventional mechanical cooling systems. 

 

PERFORMANCE FEATURES

  • Engineered to be self-supporting, impregnated and treated to provide high absorbency 
  • 12” depth will provide saturation efficiency of 90% when operated around 400 feet per minute (fpm) face velocity 
  • 2” extruded aluminum frame to provide maximum strength and minimal deflection 
  • Panels are G90 galvanized steel and base is formed G90 12 gauge galvanized up to size 120 and structural 6”, welded ‘C’ channel, on the size 160 
  • Evaporative section is constructed from single wall 304 stainless steel 
  • Sump is constructed from 16 gauge 304 stainless steel and fully welded 
  • Premium cooler pump provides water flow through clog less nozzles 
  • NEMA 3R control panel with a through the door non-fused disconnect switch 
  • Air is moved by a double width, double inlet forward curve fan which is statically and dynamically balanced
