Laor Engineering Ltd.provides oil refineries and petrochemical plants the service of an automatic hydraulically operated machine, designed to clean heat exchangers tube bundles, inside and outside the tubes.

It is a very efficient tool to use during plant shut down, when many heat exchanger bundles are pulled out for cleaning, inspection and repairs.

One man operates this machine from a protected control cabin.
3 to 5 lances equipped with jetting nozzles enter inside the tubes through their entire length, blasting the water to remove all the deposits and sludge out of the tubes, reaching a cleaning level of a new tube.

The operator moves the lances to the next group of tubes, using the hydraulic system, movement allowed horizontally, vertically and a rotation of the bundle itself if needed.

The cleaning of the outside surface of the tube is done in a similar manner. 5 nozzles with adjustable clearance between one another, to fit the bundle tube rows clearance, blast the bundle during their movement along the bundle. Up and down, in and out, and a rotation of the bundle itself.

All those movements are controlled from the control cabin, safely, quickly and efficiently!

External high-pressure pumps supply a water pressure of 800 bar, flow of 240 l/min.

Advantages: 

Very fast cleaning operation: short plant shut down period! Much money saving!
Quality of cleanliness – very high, as new, and homogeneous.
Much improved SAFETY!
No modern shut down would even be consicered without this machine.
