Quality shell and tube exchangers from specialists
ViFlow has the exclusive right to sell FUNKEs products in Finland. The company was founded in
1974 and focus on designing and manufacturing of heat exchangers for nearly all industrial
applications as well as also for the HVAC sectory.
The partnership with FUNKE broadens ViFlows product base, we can now offer the right heat
exchanger type for every customer.

In the area of shell and tube heat exchangers we can offer a mature product range of special models
for almost all requirements in machine and plant enginering. Maximum quality requirements and
customer-oriented solutions characterise the brand FUNKE. Customised process gas coolers with
operating pressure of 400 bar and above are nothing unusual. However, with the series models we
already offer our customers in our standard programme a comprehensive and high quality range of
products for all current requirements in international machine and plant engineering.
The customer receives thermodynamically optimised units which are manufacture in defined
graduations e.g. with regard to shell diameter and shell and tube length and which are available at
short notice.

 Shell and tube exchanger -structure and functioning
The shell and tube heat exchanger is a non-
fired pressure system consisting of two
separate pressure chambers (shell chamber
and tube chamber). Separated by the internal
tube wall, two media flow past one another
with such alignment that, if there is a
temperature difference, they will mutually
exchange heat without mixing in the process.
One medium flows through the shell chamber
and the second medium flows through the
tube chamber. The flow through the shell
chamber will be controlled by baffles such that
there is as much cross-flow to the tubes as
possible. The form and spacing of the baffles
will be adapted to the relevant operational use.
Depending on effectiveness, speed and
pressure loss the flow through the tube
chamber will be 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.

occur if there is a sufficient temperature
difference. The greater the temperature
difference is the smaller will be the re-quired
heat transfer surface. The heat transfer
performance of a heat exchanger is the
product calculated from the mean logarithmic
temperature difference, the heat transfer
surface and the heat transfer coefficient. The
latter will be largely determined by the flow
1. Heat exchanger shell 5. Tubesheets characteristics of the media, that is by the
2. Connection shell 6. Baffles geometric design.
3. Guide chamber 7. Apparatus seal
4. Internal tubes 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
concerns the issues of 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) as well as with FUNKE-
Software which is already used
internationally.

SWF/SWP/SSWF/SSWP
Safety heat exchanger for usage where leakage or mixing of operating media is not acceptable.
In case of leakage of the shell or tube side the corresponding change in pressure is detected by the
pressure control device in the safety space and is signalled accordingly.

SAFETY HEAT EXCHANGER

tubes and fixed ( F ) or removable ( P ) tube
bundle.

Each individual tube has a smaller internal

tube, which prevents a mixing of the following
operating media.

Double tube sheets produce the enclosed

safety space, wich is filled with a special
barrier fluid and is checked for pressure
changes.

This type is used when following issues have

special importance:
Environmental protection

Specially developed for heat recovery from the exhaust gases of stationary compustion
engines in block-type thermal power stations.

EXHAUST GAS HEAT EXCHANGER

The principle of media routing here is:

"Exhaust gas through the tubes."
Tube side one pass, more tube dimensions.
The heat exchanger has straight internal
tubes and fixed non-removable tube bundle
whose shell tube is welded to the tubesheet
so that the joint is tightly sealed. Termal
shield protects the tube/tubesheet
connections against overheating and heat
accumulation.
Axial compensator in the casing tube can be
installed. Gas side chambers are equipped
with inspection covers.
