Shell-&-Tube Heat Exchangers
Quality & safety − be it standard products or customised solutions.
A heat exchanger is an unfired pressure system in which two media flow past one another separated by as thin a wall as possible, so that if there is a temperature difference, they will mutually exchange heat without mixing in the process.
As the diagram shows, one medium flows through the shell chamber and the second medium through the tube chamber. The flow through the shell chamber is controlled by baffles, allowing as much cross flow to the tubes as possible. The form and spacing of the baffles is adapted to the application.
Depending on the expediency, speed and pressure loss, the flow through the tube chamber is carried out by a single pass or multiple passes.
With the exception of radiation losses, the input heat quantity is the same as the output heat quantity.
However, an efficient heat exchange can only take place if there is a sufficient temperature difference. The greater the temperature difference, the smaller the required heat transfer surface. This makes a compact apparatus design possible.
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 coefficient. The latter is largely determined by the flow characteristic of the media, i.e. by the design features.
On the other hand, the supplier of heat exchangers must have extensive application expertise with regard to the thermodynamic properties of special media at relevant pressures and temperatures. This also applies to the issues of fouling factors and material compatibility.
The calculation and design of FUNKE heat exchangers is carried out with worldwide leading programs (e.g. HTRI, Heat Transfer Research Institute, USA) and with in-house developed software, which is already used around the world.

Safety Heat Exchangers
When safety is your number one priority.
The range of safety shell-and-tube heat exchangers is based on the ‘three chamber devices’ principle, which was developed and patented by the company’s founder Karl-Heinz Funke.
Operating principle of a safety heat exchanger.
Here with double tubes, double sheets and leak sealing liquid.

Gasketed Plate Heat Exchangers
Design & Function
Gasketed plate heat exchangers consist of a set of adjoining embossed plates with apertures.
The plates are assembled at a 180° angle to each other, resulting in a flow gap. The gasket, which is mechanically secured or glued onto every plate, ensures that the flow gaps are securely sealed to the outside and from the second medium involved in the heat exchange.
The plate assembly is mounted in a frame and compressed with tightening bolts between the fixed plate and the movable plate.
The gaskets of a plate heat exchanger experience a normal fatigue process over the course of their service life. Depending on the conditions of use, the plate assembly can be re-tightened several times until the lower limit is reached.
The connections of the media involved in the heat exchange are on the fixed plate, but can also be on the moveable plate for multiple-pass flows. (see “Flow diagram”).
Our product range includes single and multiple-pass plate heat exchangers with heat exchange surfaces of up to 2,000 m².

New Generation of Heat Exchangers Plates
The new series FP2000 and FP4000 with new thermally and hydraulically optimized heat transfer plate. These offer a significant increase in efficiency. The efficiency in terms of heat transfer and pressure loss is improved by up to 20 %.
With a new type of embossing optimised by CFD and innovative features such as the bypass stop system, a new series has been developed here that is significantly more efficient than the previous units in this series. This makes the heat exchangers cheaper and more compact.

Brazed Plate Heat Exchangers
The TPL, GPL and GPLK series achieve a high heat transfer performance with low pressure losses. The thermodynamically optimised corrugation of the embossed stainless steel plates, as well as the special, FUNKE insert turbulence plates (TPL), produce a high turbulent flow even at low volume flow rates. This allows for an extremely efficient use of the available heat exchange area, leading to a highly efficient heat transfer. The turbulent flows also result in a powerful self-cleaning effect, which greatly reduces long downtimes and maintenance costs. FUNKE brazed plate heat exchangers can be operated with high pressures and temperatures and stand out for their compact design.
TPL - Brazed Plate Heat Exchangers
Originally developed specifically for applications such as cooling hydraulic and motor oil, TPL brazed plate heat exchangers are also ideally suited and deployable for other application processes in mechanical and plant engineering. TPL satisfy the high demands in this area with regard to reliability and thermodynamic efficiency − and can be designed with the utmost flexibility!
The exceptionally high heat transfer performance is achieved by means of diagonal media flow as well as special turbulence plates inserted into the flow gaps, a technology developed and produced exclusively by FUNKE. The turbulence plates are available in different versions, making the technical design very flexible. Each individual flow channel can be adapted to the specific application thanks to the modular design of the TPL. Another advantage of the TPL is its high resilience, as the surface soldering makes it possible to achieve a significantly higher level of safety under stress compared to the spot soldering used in conventional brazed plate heat exchangers. Stress conditions in the heat exchanger caused by differences in pressure or temperature, for example, can be absorbed significantly better thanks to the surface soldering of the TPL. TPL can be used universally with different media. Small sizes with low space requirements are possible for media with higher viscosity thanks to the high heat transfer of the powerful TPL. The optional extended end plates also facilitate the installation of the already very compact units.

This includes, in the first instance, the Okan 2.79 cooler series, which can be adapted to suit a wide range of customer requirements due to its modular design. For example, special designs are available for marine and offshore applications, or for installation in areas where there is a high risk of explosion.
The Okan E series is also available. The Okan E series oil/air coolers have been specially developed for standard applications in the industrial hydraulics sector which do not impose any special requirements on the design of the oil/air cooler.
In addition to extensive documentation, 3D models of all oil/air coolers are included as step files.
Design and function
The basic element is an aluminium cooler in bar and plate construction, as shown below. The oil tubes are fitted with turbulence elements to guarantee optimum heat transfer.
The fan mounted behind the cooler operates as suction in standard mode. The slat shape, fan blades and motor power are aerodynamically and thermodynamically coordinated to achieve a high degree of heat dissipation.
