• The work horses under the heat exchangers are the Shell & Tube Heat Exchangers.
• They are extremely reliable, and because of extensive research, predictable in their
‘behaviour’.
• Often they are the solution to a rather specific problem. Many thermo mechanical
engineers delight in designing the optimal Shell & Tube Heat Exchanger for such
special cases.
• And there are a lot of special cases in the world of heat exchangers that need a
special solution.
• One of the problems that often needs a special solution is the fouling of the heat
exchanger.
• It occurs in al heat exchangers, but in some cases the fouling is so severe that for
example three heat exchangers are required to guarantee continued operation.

• Then there is one in operation, one opened to be cleaned and one on standby for when
the first one becomes fouled again.
• It leads to enormous expense for maintenance and a lot of “over design” is needed to
compensate for the reduced heat exchange.
• The patented Klarex® heat exchanger is a special design of a Shell & Tube Heat
Exchanger, but with an important difference. The Klarex® heat exchanger prevents fouling.
• No matter how long it is in use, the inside of the tubes stay clean.
• The Klarex® heat exchanger does not need maintenance, does not use more energy and
does its work uninterrupted and reliable for many years to come.
• The secret of the Klarex® heat exchanger are the addition of metal anti-fouling particles.

• In the vertical pipe shell heat exchanger, metallic anti-fouling particles are continuously
circulating with the fouling fluid.
• These metal particles prevent fouling of the pipe walls from the start. Furthermore, they
also serve as turbulators for improving the heat exchange.
• A multiple path distribution system provides a uniform distribution of the particles across
the pipes.
• Besides that, the system creates homogeneous mixing. Also, the quantity of the anti-
fouling particles is adjustable.
• The anti-fouling Klarex® heat exchangers are equipped with an external fall pipe for the
particles.

• This has several advantages:
• - partical circulation is done with a lower downward particle speed, resulting in less wear of
the fall pipe bottom;
• - both the rate of distribution, as well as the concentration and the circulation of particles in
the fall pipes is easier to inspected and monitor with an internal fall pipe;
- there is no risk of unequal distribution of the particleflow in between the various parallel
internal fall pipes;
- when the heat exchanger is taken out of service, it is easy to remove most of the
particles. This is advanteous for startup of operations of the heat exchanger, as well as
inspection.
• The Klarex® heat exchangers are suitable for many different applications, for they already
have been tested extensively.
