Aluminum louvers are used for precise control of process

temperature and power saving for Air Cooled Condensers

and Air Cooled Heat Exchangers.

Some fluids have low pour point which results in

crystallization and/or freezing of heavy hydrocarbons

especially during winter when air temperature is extremely

low. Louvers are used for winterization application for sub-

zero air temperatures.

Other application of louvers is to conserve power due to variations in atmospheric temperature. In

winter, air quantity can be reduced thereby reducing power consumption by fan.

Louvers are designed both for

induced and forced draft

applications. For forced draft

application, the louver frame is

made of Aluminum sections and

for induced draft the frames are

made of Carbon Steel.

Louvers can be either parallel blade or opposed action. An opposed action louver has a broader and

more linear control range which can be effectively utilized with appropriate controllers.

Louver blades are of extruded aluminum sections with special profile designed for minimum air

leakage in fully closed condition. Glass Filled Nylon / Teflon bushes are provided for each of the

blade shaft to facilitate smooth opening and closing of louvers with least effort. Teflon bushes

provide longer life to the operating

mechanism of the louvers.

Auto–variable louvers with pneumatic

actuators, positioners, volume booster

and I to P converter are offered.

Alternatively, manual operations with

either pneumatic controls or link

mechanism to operate from the grade

level of the air cooler are also offered.
