The Services

External Fin Tube Cleaning

It also used for Heat rejecting from a hot process fluid to the surrounding atmosphere by using the atmospheric air as a cooling media.

The equipment is basically designed with multiple rows of finned tubes in a series of surface and required numbers of fans are used to move the low temperature atmospheric ambient air over the finned tube coil surface in order to cool the hotter fluid media. It is also consists of several mechanical and electrical components eg axial flow fan, motor, shaft, bearings, sprocket etc.

It is extensively used in Oil & Gas, Petrochemical, Refinery and Power plants. All type of fluids in process industries are cooled in Air Fin Coolers with the use of atmospheric air, as the cooling media which resulting in economy in running costs.

The Design

The system specially designed to cater for all type of Air Cooled Condenser, Forced Draft, Induced Draft and A-Shaped type.

This lightweight Automatic Cleaning System is assembled and attached to the upper rail of the Air Cooled Condenser where the Cleaning Head and Motor are fitted.

The Cleaning Head traverses up and down the beam and after each stroke the Cleaning Rig is moved along achieving a full clean right up to the top of the bundle of the Air Cooled Condenser.

The unit is pneumatic and self powered. At the end of each stroke the direction is reversed automatically.

The horizontal beams are telescopic to make the unit suitable for almost any bundle width. The height the system is 170 mm. This enables operation in narrow spaces of the Air Cooled Condenser.

The Process

The Cleaning system consists of hydro-jet system which uses only water and no chemical with the water pressure of 80-100 bar and flow of 150-300 l/min.

The Cleaning Head and the nozzle pitch specifically designed to suit the bundle and the finned tube arrangement of the Air Cooled Condenser.

The tube row arrangement from the data sheet of the Air Cooled Condenser will determine the correct spraying angle for the flat razor blade water beam to cut through any external fouling and penetrates through the bundle.

The spraying angle is fixed throughout the cleaning process in order to prevent any damage to the finned tube by the water force.

Wrong pitch angle
Correct pitch angle

The Implementation

The cleaning process can be done even during plant operation unlike the conventional cleaning method uses manpower which only can be implemented during once a year scheduled plant shutdown. And each Automatic Cleaning System can operate 2 – 4 Air Cooled Condenser in a day shift.

High pressure water beam penetrates through the bundle
20% - 25% airflow improvement ‘the product flow increased as the product temperature decreased

The cleaning process remove the debris and obstruction for the air and the airflow increased with the factor 2 – 3. As the cooling performance increased, the product flow increased which results to the increased in production.

The Advantages

TRADITONAL

Require several skilled manpower for standard hydro-jet system as it is difficult to maintain pitch spraying angle with the pressure of min 80 bar.

As a result, this would damage the finned surface

Manpower safety concern as working in a hazardous area environment with a process temp of approx. 70 - 110 degree celcius.

Only managed to clean 1 finned tube bundle a day

CHEMICAL

Require several skilled manpower for using chemical spraying system and water flushing via hydro-jet system.

Chemical foaming could not reach the middle part of the finned tube as it is blocked by the existing fouling.

Manpower safety concern as working in a hazardous area environment with a process temp of approx. 70 - 110 degree celcius.

Only managed to clean 1 finned tube bundle a day

AUTOMATIC

Fully automatic and no manpower needed during cleaning process.

Fixed spraying angle according to the given datasheet throughout the whole cleaning process. As a result, the water will penetrates through the whole finned tube and would not damage any finned tube surface.

No manpower involes during cleaning process even during plant operation

Managed to clean up more than 4 finned tube bundles a day depending numbers and rows of installed nozzle.
