About Indirect
Dry Cooling Tower

The indirect dry condensing system couples an indirect dry cooling tower (IDCT) with a steam surface or jet condenser, and is suited for large capacity condensing units. Its tall concrete or steel shell eliminates hot air recirculation. Thanks to the natural draft of cooling air, auxiliary is power minimized, as is the number of mechanical components. This translates into reduced maintenance and high availability.

The mechanical Indirect Dry Cooling Tower is particular type of IDCT where the cooling air flow is not driven by the natural draft from a tall concrete or steel tower , but is induced or forced by fans driven by electrical motors. M-IDCTs are particularly suitable for the Wet to Dry conversion or cooling capacity extension of existing IDCT.

Features of
Indirect Dry
Cooling Tower

An indirect dry condensing system connects a dry cooling tower with a steam condenser. The steam that flows from the turbine is condensed by cold water in a surface condenser or a jet condenser. The heated water is pumped to vertically arranged heat exchangers that are located around the concrete tower. The natural draft cooling tower generates the airflow across the heat exchangers.

01

Sustainable

An indirect dry cooling solution reduces auxiliary power and eliminates additional water usage from the condensing power cycle. The large concrete shell prevents hot air recirculation.

02

Flexible

Indirect dry cooling systems offer flexibility in power plant site selection. A flue gas desulfurization unit (FGD) can be installed inside the tower.

03

Quality

There is no visible plume or high operational noise coming from the indirect dry cooling tower. It has a stable steam turbine back pressure.

04

Low maintenance

Indirect dry cooling systems have few rotating parts, which results in a low maintenance.
