Structure and function
The shell-and-tube heat exchanger is a non-red pressure
system consisting of two separate pressure chambers
(shell chamber and tube chamber). Separated by the inter-
nal tube wall, two media ow past one another with such
alignment that, if there is a temperature difference, they
will mutually exchange heat without mixing in the process.
As the picture shows, one medium ows through the shell
chamber and the second medium ows through the tube
chamber. The ow through the shell chamber is controlled
by bafes such that there is as much crossow to the
tubes as possible. The form and spacing of the bafes
is adapted to the relevant operational use.
Depending on effectiveness, speed and pressure loss
the ow through the tube chamber is effected by a single
pass or by multiple passes. With the exception of radiation
losses, the input heat quantity is the same as the output
heat quantity.

However, an effective heat exchange can only take place
if the temperature difference is sufcient. The greater the
temperature difference, the smaller will be the required
heat transfer surface. The heat transfer performance of
a heat exchanger is the product of the mean logarithmic
temperature difference, the heat transfer surface and the
heat transfer coefcient. The latter is largely determined
by the ow characteristics of the media, that is by the
geometric design.
On the other hand, the supplier of heat exchangers must
have a wide application know-how with regard to the
thermodynamic properties of special media at pertinent
pressures and temperatures. This also applies for the
issues fouling factor and material compatibility.
The calculation and design of FUNKE heat exchangers is
effected with worldwide leading programs (e.g. HTRI, Heat
Transfer Research Institute, USA) and with FUNKE-Soft-
ware which is already used internationally.

connection chambers, using a 3/8 NPT thread. The blind
hole bore provided becomes a through hole on complete
breakdown of the anode and signals the point in time when
replacement is required. As standard, no production draw-
ing is supplied for this model series.
Application
Very wide range of application for all current heat engi-
neering tasks. In accordance with the requirements due to
the operating media and environmental conditions these
types are frequently used as uid coolers for oil, water or
other operating uids. The operation with steam is only
possible on the shell side and subject to restrictions. Con-
taminated operating media must preferably be led through
the tubes. A high velocity of ow which is to be aimed for is
possible due to the multi-pass design.

Universal
Technical Description
Model series for universal use in modular system con-
struction with exchange surfaces of 0.11 m to 11.45 m.
110 graduated building sizes in three principal material
groups with two possible construction designs respective-
ly (xed tube bundle or removable tube bundle) provide the
basis for an optimum and detailed type selection:
Whilst the versions with a xed tube bundle are available
in a tube side single-pass, two-pass or four pass version,
the versions with a removable tube bundle are for design
reasons only available in a tube side single-pass or two-
pass version. The subdivision of the tube bundle geometry
into an O-version and a W-version offers excellent pos-
sibilities for the optimisation of heat transfer and pressure
losses: In the O-version a narrow bafe spacing produces
an excellent heat transfer at low pressure losses. This
version is to be selected preferably for thin liquid operating
media. The W-version, with its wide bafe spacing, imple-
ments the compromise between an excellent heat transfer
and acceptable pressure losses. Due to the bundle geo-
metry, favourable in uid engineering terms, this version is
parti-cularly suitable for viscid operating media. All types
of this standard series are available in horizontal or upright
version. When using internal tubes made of CuZn28Sn1As
(CW706R), CuZn20 Al F34, CuNi30Fe F37 and SF-Cu, as
standard the tube bundle heat exchangers of type BCF,
BCP, CCF and CCP are equipped with sacricial anodes in
order to extend the operating periods or service life of the
apparatus. These sacricial anodes made of tin (tin pro-
tection rod) are screwed with a square into the tube side

Model series TDW
Turbo-Spin
Technical Description
The FUNKE heat exchangers from the TDW series (Turbo-
Spin heat exchangers) are very compact heat exchangers
with an removable tube bundle, which were developed
for the cooling of hydraulic oils or hydraulic replacement
uids* (see table). Exchanger surfaces from 0.15 m - 4.00 m
can be installed in xed and reasonably graduated building
sizes. The thermotechnically highly efcient spin-shaped
oil ow on the shell side is generated by the arrangement of
special helical screws whose pitch can be adapted to the
ow quantity.
Two versions are available: With the O version (low helical
screw pitch) for liquid oils and the W version (high helical
screw pitch) for viscid oils, compromises are provided
between an optimum heat transfer and pressure loss. The
oil end tin-plated ribbed tubes bent into U-shape are xed
by means of helical screws and also are moulded leakage
free into the tubesheet made of synthetic material. The
sealing of the xed tubesheet between heat exchanger
shell and connection chamber is effected by means of
O rings. Due to the multipass design on the tube side good
velocities of ow are reached even with small quantities of
cooling water; these counteract a possible fouling of the
interior tube wall. All connections at the shell-and-tube end
are designed with a Whitworth internal tube thread (G).
Application
Wherever a safe and uncomplicated oil cooling system is
required. The integration in oil supply systems or drive and
control units represent only some of the many possibilities.

Model series CCFA, SSCFA
Gas cooling
Technical Description
The heat exchanger CCFA (SSCFA in stainless steel version)
is a further development of the proven heat exchanger
model series BCF for use as a gas cooler.
The CCFA has been designed with a xed tube bundle and
is only available as a tube side single-pass version (gas
owing through the tubes), thus it can easily be integrated
into the gas pipework.
The cooling water is routed on the shell side in a counter-
ow direction. Optionally a horizontal or vertical tting
position is possible.
In the event of condensate occuring there is the option
of precipitation an phase separation by the downstream
connection of a condensate separator (cyclone separator).
Here, however, attention should be paid to a suitable tting
position.
Application
The operational range of these heat exchangers as air or
gas coolers is very wide and varied. For example, they are
used in connected plants with multi-stage compressors
as intermediate coolers or after coolers and as individual
coolers wherever compressed gases need to be cooled
but also dried. Gas preheating with suitable heating media
is also possible.

Model series SWF / SWP, SSWF / SSWP
Safety
Technical Description
SWF safety heat exchangers are designed as three
chamber devices with straight internal tubes and xed
(F) or removable (P) tube bundle.
In each individual internal tube of the tube bundle a further
smaller internal tube is installed. These concentric internal
tube pairs form radial gaps which are interconnected by
the design of the double tubesheets and thus produce the
enclosed safety space. A mixing of the owing operating
media is prevented in this way.
This sealed safety space is lled with a special barrier
uid and is checked for pressure changes by means of a
pressure control device.
In order to prevent any increases in pressure and thus a
false alarm due to thermal expansion of the barrier uid,
the safety space is additionally tted with an equalizing
vessel.
In the case of a leakage of the shell or tube sides the cor-
responding pressure change within the safety space will
be detected by the pressure control device and signalled
accordingly.
Application
FUNKE safety heat exchangers are used wherever a leakage
or mixing of both operating media is not acceptable during
uid cooling or uid heating.

Model series CPS
Standard
Technical Description
The CPS-(CP-Standard) model series was developed on
the basis of the TEMA type BEW and represents a delimi-
tation relative to customized individual solutions, achieved
by reasonable standardization. Systems with a heat
exchanger surface of 0.47 m - 104.02 m can be realized
at a very economical price / performance ratio and with
the known FUNKE quality.
The CPS has straight internal tubes and an removable tube
bundle whose xed tubesheet is clamped in between the
shell side and tube side device anges by means of two
at seals and bolts.
On the side of the oating movable tubesheet, the combi-
nation of two sealing rings and a leakage ring between the
device anges protects against a mixing of the shell side
and tube side owing media.
In the case of leakages due to a single or both selaing
rings being defective the pertinent media always escape
towards the outside through signal bores on the circum-
ference of the leakage ring.
All seals of this design seal against atmosphere.
The tube / tubesheet connections are produced exclusively
by roll expansion.
There are two versions of the connection and guide cham-
bers available by means of which a tube side single-pass
or two-pass version can be generated and whose selec-
tion is effected according to uid engineering criteria.

Model series WRA 200
Exhaust gas
Technical Description
The model series WRA 200 represents a special design
for exhaust gas cooling. The principle of media routing
here is: Exhaust gas through the tubes, with tube side
single-pass execution being selected exclusively. The
heat exchanger has straight internal tubes and a xed
non-removable tube bundle whose shell tube is welded to
the tubesheets such that the joint is tightly sealed. Due to
its design, the WRA 200 can be equipped with a maxi-
mum possible and optimum tubing. The tube / tubesheet
connections are produced by pertinent tube weldings in
accordance with the construction regulations and material
combinations as well as the maximum permissible operat-
ing parameters (P / T). Naturally, to avoid gap corrosion,
after a tube welding the internal tubes are roll expanded
again. Maximum exhaust gas temperatures at the gas
entry side will be transferred without any hazard and with-
out any detrimental effect on the service life as a thermal
shield protects the tube / tubesheet connections against
overheating and heat accumulation, and thus prevents
material fatigue or cracking in the tubesheet.
To prevent the generation of non-permissibly high axial
forces due to thermal length changes, caused by different
operating states and / or material selection, an axial com-
pensator can be installed in the casing tube. Both connec-
tion chambers of the exhaust gas side are equipped with
inspection covers for easy cleaning of the internal tubes
without disassembly of the exhaust gas lines.

tube dimensions can be adapted according to customer
requirements.
Material selection
In accordance with the respective regulations and con-
struction regulations, stainless steels are used for the
internal tubes, tubesheets and bafes as well as for the
outlet gas chamber. The inlet gas chamber and the casing
tube are manufactured from carbon steel. An integration of
other material combinations or the use of special materials
is possible.

Application
This heat exchanger type CP is mainly used as an oil
cooler or double oil cooler, where the oil should ow on
the shell side whilst the cooling water ows through the
internal tubes. This heat exchanger is used also for cooling
other uids as well as air or similar gases with and without
any condensable content. Any operation with gases having
a low molecular weight (e.g. hydrogen) is not effective due
to the type of seal used on the oating tubesheet.
Acceptance
The FUNKE heat exchanger of type CP can be supplied
in accordance with all pertinent national and international
certication bodies, regulations and construction regula-
tions as e.g. pursuant to the Pressure Equipment Directive

Model series CP (e.g. TEMA Type BEW; AEW)
Technical Description
The FUNKE heat exchanger type CP is a heat exchanger
with straight internal tubes and removable tube bundle
whose xed tube-sheet is clamped in between the shell
side and tube side device anges by means of two at
seals and bolts. The movable tubesheet, oating due to
the combination of two sealing rings and a leakage ring
between the device anges, protects against a mixing of
the shell side and tube side owing media.
In the case of leakages due to a single or both selaing
rings being defective the pertinent media always escape
towards the outside through signal bores on the circum-
ference of the leakage ring. All seals of this design seal
against atmosphere.
The tube / tubesheet connections are produced by appro-
priate tube expand rollings or tube weldings in accordance
with the construction regulations, material combinations
and operating media as well as the maximum permissible
operating parameters (P / T). Naturally, to avoid gap cor-
rosion, after a tube welding the internal tubes are roll
expanded again.
The connection and guide chambers are available in differ-
ent versions, which can be produced by a tube side single-
pass, two-pass or four pass design and whose selection
is effected in accordance with the standards required and
with uid engineering aspects.
Venting and draining points as well as a corresponding
foot construction are designed in relation to the installation
position.
Material selection
In accordance with the respective regulations, construc-
tion regulations and operating media, carbon steels, stain-
less steels as well as non-ferrous heavy metals are used.
A reasonable integration of special materials, platings and
coatings is possible.

Gas cooler, tube bundle removable
Model series A 100 (e.g. TEMA Type BEW; AEW)
Technical Description
The FUNKE heat exchanger type A 100 was designed in
accordance with type CP and is exclusively available as a
gas cooler - media routing gas through the tubes in a
tube side single-pass version. It is a heat exchanger with
straight internal tubes and a removable tube bundle whose
xed tubesheet is clamped in between the shell side and
tube side device anges by means of two at seals and
bolts. The movable tubesheet, oating due to the combina-
tion of two sealing rings and a leakage ring between the
device anges, protects against a mixing of the shell side
and tube side owing media. In the case of leakages due
to a single or both selaing rings being defective the per-
tinent media always escape towards the outside through
signal bores on the circumference of the leakage ring. All
seals of this design seal against atmosphere.
The tube / tubesheet connections are produced by
appropriates tube expand rollings or tube weldings in
accordance with the construction regulations, material
combinations and operating media as well as the maximum
permissible operating parameters (P / T). Naturally, to avoid
gap corrosion, after a tube welding the internal tubes are
roll expanded again.
The connection chambers are available in various differ-
ent versions whose selection is effected in accordance
with the required standards and in accordance with uid
engineering aspects.
Venting and draining points as well as a corresponding
base construction are designed in relation to the installa-
tion position.

Application
This heat exchanger type C 100 is mainly used where, in
addition to the requirement for a removable tube bundle
and good cleaning possibilities, a higher quality for the
tube side sealing type is required in relation to the operat-
ing media, pressure and temperature. Due to its boundary
conditions it is highly suitable for uid operating media but
also as a gas cooler with and without partial condensation;
however, critical media should ow on the tube side.
Acceptance
The FUNKE heat exchanger type C 100 can be supplied
in accordance with all pertinent national and international
certication bodies, regulations and construction regula-
tions as e.g. pursuant to the Pressure Equipment Direc-
tive (PED), AD-2000, ASME-VIII, Div. I, U-Stamp, TEMA

Application
Due to its design this heat exchanger type C 300 can be
used universally. The internal tubes bent in a U-shape,
which are exclusively attached to the xed tubesheet,
permit operation at very high temperatures and pres-
sures without any thermal stresses, thus avoiding damage
occurring on the tube / tubesheet connection. This heat
exchanger can be used for the partial or full condensation
of gases and vapours but also as a uid cooler / heater.
On principle the media routing can be freely selected, but
the clean operating medium should preferably ow through
the tubes as a mechanical cleaning of the internal tubes
bent in a U-shape is only limited feasible.
Other design options as e.g. the version with a two-pass
shell or as a suction cooler for tank installation expand the
operational possibilities of this type.
