Induced draft axial fan counterflow closed circuit cooler. The ATW cooler is used for cooling of water or water/glycol mixtures. The process fluid remains without oxigen and impurities. Executed as per standard with Z-725 (725g/m² zinc) galvanized steel panels.
The ATW (Advanced Technology) design combines low energy consuming axial fans with high performance counterflow heat exchange.
EVAPCO’s Thermal-Pak® coils feature a patented design which assures maximum cooling capacity. The elliptical tubes of the coil are staggered in the direction of airflow to obtain a high heat exchange coefficient. The coils are manufactured from high quality steel tubing following the most stringent quality control procedures. The assembled coil is pneumatically tested under water in accordance with the European Pressure Equipment Directive (PED) 97/23/EC.
The ATW cooler range is CTI (Cooling Technology Institute) certified in the USA. Evapco Europe provides with each cooling tower a Thermal Performance Guarantee. ATW-units are constructed for a maximum nominal capacity of 12 MW.
Long-lasting corrosion protection is guaranteed with Z-725 heavy gauge mill hot-dipp galvanized steel (Z-725 = 725 g/m² zinc). The galvanized steel construction withstands the most difficult environmental and operating conditions.
For special applications, Evapco can produce the units with stainless steel sump, with a water touched stainless steel construction or a complete stainless steel construction(AISI 304 or 316 are possible).
