ERI – Stainless Steel Evaporative Cooling Tower with Radial Fans and Indirect Heat Transfer

The closed cooling tower is primarily used where high demands are placed on the cooling water quality, such as in the cooling of machinery with narrow cooling channels.

Der geschlossene Kühlturm findet vor allem dort seinen Einsatz, wo hohe Ansprüche an die Kühlwasserqualität gestellt werden, z.B. bei der Kühlung von Maschinen, in denen sich enge Kühlkanäle befinden.

Operating Principle

The cooling of process heat is achieved by the evaporation of the natural refrigerant, water, where a heat and mass transfer occurs between the cooling water and the surrounding air in a counterflow. In a closed-circuit evaporative cooler, the surrounding air does not directly contact the cooling water: Water flows through a closed pipe system, forming the primary circuit, for the cooling of a consumer. Clean water, preventing deposits, is always in circulation. For the re-cooling of the primary circuit, the pipe system is wetted with pumped water from the secondary circuit, which is then cooled by evaporation.

Primary Circuit

Hot-dip galvanized smooth tube heat exchanger made of steel (optionally also in stainless steel) with a high exchange surface enables safe operation.

Secondary Circuit

The water distribution for spray water occurs via a pipe system made of galvanized steel (for ERI: made of stainless steel), featuring plastic hollow cone nozzles. Easy disassembly is ensured through plug connections (in the stainless steel version) or screws (in the galvanized version). Water distribution is facilitated by an external pump and stainless steel riser pipe.
