Hamon in a few words
Hamon started its industrialactivities in Europe (Belgium and
France) a century ago and devel-
oped the cooling tower business.
Hamon spread its wings geo-
graphically in the seventies and
urther consolidated the thermal
business in the nineties. Hamon
became a world leader in the
product lines it chose to be in,
respectively:
Wet cooling towers
Air-cooled heat exchangers
Air pollution control
Chimneys
With over 50 years o experience
in the ield o heat exchange,
Hamon DHondt can address and
resolve all clients needs in air-
cooled heat exchange.
Hamon DHondt designs and
manuactures air-cooled heat
exchangers (ACHE) and fnned
tubes and can oer their products
to chemical, petrochemical, pow-
er and heat recovery industries.
Hamon DHondt has developed
signifcant innovative technologies
in the design and abrication o
high pressure equipment and in
the manuacturing o components
made with special materials such
as Titanium, Hastelloy, Incoloy,
Duplex, Super Duplex, Monel
and Nickel Alloys.
Thanks to its consolidated design
and manuacturing experience
combined with the adoption o
improved design and abrication
concept, Hamon DHondt is
able to give a high technological
contribution to the completion oindustrial plants and implemen-
tation o energy programs world-
wide.
Hamon DHondt specialises in the
design and manuacture o the
ollowing products or chemical,
petrochemical and power gener-
ation plants:
Air-cooled heat exchangers
(API 661)
Tube bundles
Aluminium fnned tubes
High requency and studded
welded fnned tubes
The complete service starting rom
thermal and mechanical engineer-
ing to the complete manuacture,
including the internal design andsupply o the main components
like fnned tubes, an hubs, an
blades, etc, guarantees Hamon
DHondt supplies or the best
perormance and efciency.

Hamon DHondt has two acto-ries: the main one in Fresnes-
sur-Escaut, France and a new one
in Jubail Industrial Area, Saudi
Arabia, to serve more specically
the Middle East markets.
French actory
Hamon DHondt has a large ac-
tory in Fresnes / Escaut (France)
with a covered area o 17.550 m2
on a total surace o 115.000 m2.
The workshops are equipped with
the most modern machinery or
proper manuacturing and control
o the complete air-cooled heat
exchangers.

Saudi Arabia actory
Hamon DHondt has a actory
in Jubail Industrial Area (Saudi
Arabia) with a covered area o
3.500 m2 on a total surace o
12.000 m2.
The workshops in Saudi are
perorming tube nning, bundle
assembly, air-cooled heat ex-
changer modularizing, and all
relevant tests (hydrotest, helium
leak testing, vibrations, noise...),
whereas the pressure parts
(headers) are being manuactured
in France and shipped to the
Jubail actory.

Air-cooled heat exchangers
The air-cooled heat exchangersare mostly used when the plant
location and the ambient condi-
tions do not allow an easy and
economic use o other cooling
systems.
The most evident advantages o
air-cooled heat exchangers are:
No problem arising rom ther-
mal and chemical pollution o
cooling fuids
Flexibility or any plant location
and plot plan arrangement
(installation over other units)
Reduction o maintenance costs
Easy installation by bolted
assembly
Lower environmental impact
than shell and tube heat ex-
changers thanks to the elimina-
tion o an auxiliary water supply
Hamon DHondt provides com-
plete aircooler units including
tube bundle assembly, motor-an
groups, structure, access ladders
and walkways. Typical arrange-
ment can be orced drat, induced
drat, or air-recirculation unit.Hamon DHondt also supplies
pre-assembled modules.
Typical components include
headers, nned tubes, and
motor-an assembly.

Forced drat
Allows easier maintenance o the
ans. Fans deliver air at ambient
temperature with consequent
higher eciency.
Induced drat
The plenum chambers are mount-
ed on top o the bundle and
protect the nned surace against
wind, rain, snow and partially hail.
The location o the ans also
ensures an optimum air distribu-
tion, limits air recirculation and
allows lower level at maintenance
walkway level. Fans deliver hot air.
Recirculated / Winterization
This eature is recommended or
special processes (hydrate pre-
vention..) and cold climates,
where it is advisable to provide
warm air by recirculation to pre-
vent reezing. The recirculation
may be achieved by means o
louvers, steam coils and variable
ans.

Tube bundles tailor made
Hamon DHondt designs andmanuactures interchangeable
tube bundles using top perorm-
ance equipment.
All types o air-cooled bundles can
be replaced with no alteration o
the heat exchange capacities and
are ully adaptable to existing
piping and existing structure.
The replacement bundles are
re-designed according to the latest
code editions and innovation
standards.
Retubing
Hamon DHondt perorms the
re-tubing o tube bundles; this is
directly made in our workshops.
Hamon DHondt also manuac-
tures ully interchangeable nned
tubes.

Aluminium KLM type
KLM nned tubes are Hamon
DHondt proprietary development.
Manuacturing process
The ns are composed o an
aluminium or copper strip
tightly wound around the tube
The bases o the ns orm a
perect seal, thus oering totalprotection to the underlying
tube
The tube and base o the ns
are simultaneously knurled
together, thus guaranteeing a
perect t between the n and
the tube to provide optimum
heat exchange
Advantages o the KLM fn system Tube protected against corrosion
Resistant to vibrations
May be used at temperature
up to 320C (608F)
Unique combination o high
thermal perormance and
stress resistance with atmos-
pheric corrosion protection
KLM can avorably replace any
type o nned tubes
Aluminium fnned tubes
Aluminium Extruded type
Manuacturing process
An aluminium mu is shrunk
onto a bare tube, which has
been careully degreased rst
The assembly is passed through
the machine by means o a set
o rotating disks
The compression o the disksaround the aluminium mu
results in the extrusion o the
aluminium around the base
tube, thus causing the orma-
tion o the ns
The pre-stressing o the alu-
minium mu means that the
ns are held perectly around
the base tube
Advantages o the extruded
fnning process
Tube protected against corrosion
Fins have extra rigidity
Heat transer remains constant
May be used at temperatures
up to 300C (572F)
Aluminium Embedded G type
Manuacturing process
A groove is cut in the bare tube
by metal liting
The strip is embedded under
tension into the groove and
pressure is applied to the lited
metal to x the n
This manuacturing processensures that the n is xed
tightly to the tube, providing
optimum heat transer
Advantages o G fns
Provides a perect t between
the n and the tube
May be used at temperatures
up to 400C (752F)
Hamon DHondt produces a wide range o fnned tubes (with aluminium ns) or all industrial sectors andis ully equipped to test the contact between tube and ns ensuring the expected thermal perormances
(pull and push test, ...).
