Air-Cooled Condensers (ACC) and Air Coolers (AC)

Air-cooled steam condensation for the removal of redundant heat generated within the technology in various industrial plants.

The air-cooled condenser (ACC) of water steam is used for the removal of low-potential heat during the water steam condensation. In principle, it cools with atmospheric air with a forced air draft. The area of ribbed tubes is used for the heat transfer where the cooling air flows outside the tubes, and the condensing medium, steam, flows inside the tubes. Forced air flow is provided by a propeller fan. The fan is driven by an electric motor with gearbox.

The air cooler (AC) is used for cooling the heat transferring media. In principle, it cools with atmospheric air, with forced air draft. The heat transferring medium is not in direct contact with the cooling air. The area of ribbed tubes is used for the heat transfer where the cooling air flows outside the tubes, and the heat transferring medium flows inside the tubes. Forced air flow is provided by a propeller fan. The fan is driven by an electric motor with gearbox.

Components:

tube bundles
manifold header bringing steam into tube bundles
fans delivering cooling air, including fan stack
sheathing
steel structure for fixing the components mentioned above
steel walkways and ladders
collecting chambers of cooled medium

Industry application:

energy industries
petrochemical industry
chemical industry
engineering industry and metallurgy
plastic and rubber industry
paper industry
manufacturing industry (food-processing, sugar refineries)

Benefits of dry cooling:

low consumption of water (suitable in cases where water is critical or costly)
low environmental burden (no chemicals are used for water treatment, there is only a minimum risk of technical substances leakage into underground/surface water)
low maintenance costs
longer service life – lower corrosion load with the cooling medium
no evaporation or water escape (used in urban areas)
option of primary circuit cooling
