HomeCooling TowersClosed Circuit Fluid Coolers

ATW

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).

ESWA

ESWA

The ESWA is an induced draft, counterflow design closed circuit cooler with a CTI Certified capacity range of 900 to 18500 MBH (264 to 5422 kW). Standard construction includes the patented, high efficiency Sensi-Coil® technology, EVAPAK Fill and G-235 (Z725-Europe) galvanized steel casing and basin. Type 304 stainless steel construction is available for the basin or the entire unit. The ESWA Closed Circuit Cooler is an Advanced Technology, induced draft counterflow design closed circuit cooler featuring EVAPCO’s patented Sensi-Coil® technology – the most efficient in the industry. The counterflow design provides the ESWA Closed Circuit Cooler with inherently better operational and maintenance features. The ESWA is now standard with CTI Certified Performance including the Super Low Sound Fan option. The warm process fluid circulates from the heat source to the coil of the closed circuit cooler. The fluid in the coil transfers its heat through the coil tube walls in a sensible exchange to the spray water that floods over the tubes. Having gained heat from the coil, the spray water then falls to the sump where it is circulated by the spray pump up through distribution piping to the spray nozzles. The warmed spray water is then distributed as a thin film over the fill-deck surface for maximum cooling efficiency. The fan system operates simultaneously, moving large volumes of air through the unit in a direction opposite the falling water. The air and water contact directly across the fill-deck surface whereupon a small portion of the spray water is evaporated. The evaporation process provides a latent exchange of heat from the spray water to the air passing through the unit. The air is then discharged from the unit as a warm and saturated stream with a final dissipation of heat to the atmosphere. The spray water exits the fill-deck module as a cooled fluid where it floods across the coil in a repeat cycle.

LRW

Forced draft centrifugal fan counterflow closed circuit cooler. The LRW cooler is used for cooling of water or water/glycol mixtures. The process fluid remains without oxygen and impurities. Executed as per standard with stainless steel AISI304 sump and Z-725 (725g/m² zinc) galvanised steel casing. A LRW cooler is the ideal solution for sound-sensitive installations due to the centrifugal fan with forward curved fan blades to allow static pressure for the installation of sound-attenuators. 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 LRW cooler range is CTI (Cooling Technology Institute) certified in the USA. Evapco Europe provides with each cooling tower a Thermal Performance Guarantee. LRW-units are constructed for maximum nominal capacity of 0,8 MW.
