A process-cooling system introduced from Italy as a more efficient alternative to cooling towers or central chillers has undergone a redesign that further increases its cooling capacity. The new Ecodry EDK model from Frigel NA, East Dundee, Ill., replaces the former EDG version. This V-shaped adiabatic chamber allows for greater, unrestricted airflow into the unit. It also has redesigned cooling coils and improved mist atomization. These and other changes are said to allow greater overall cooling capacity, better humidification of the air in the adiabatic chamber, and reduced air pressure in the chamber. According to Frigel, the increase in cooling capacity can be substantial in cooler, dryer climates but less so in hot, wet regions. (Frigel has new software that uses climate data for a customer’s location to calculate the effective cooling capacity of an Ecodry unit.) The Ecodry system sits outdoors and cools plant water with ambient air. Unlike a cooling tower, the process water circulates inside finned “radiator-type” coils, where heat is removed by fans with energy-efficient, brushless DC motors. This closed system eliminates dirt and contamination, as well as scale formation, and requires little or no make-up water. At ambient temperatures above around 85 F, the Ecodry system switches automatically into adiabatic mode, which uses a fine spray of tap water to cool the ambient air through evaporation. But unlike other adiabatic systems, the water mist does not directly contact the cooling coils, so no scale buildup occurs. The new EDK design uses even less water than before. Frigel says the Ecodry system uses 99.4% less water and 34% less energy than a tower and 94% less energy than a central chiller. (847) 540-0160 • www.frigel.com/na

On many extrusion shop floors, there’s likely a more experienced staffer who can tell something’s amiss with a line using only the instrumentation God gave him or her.
