Semi Welded Heat Exchanger (FPG):

– Refrigeration Engineering without any Risk. Gasketed plate heat exchangers reach their limits when it comes to critical media as e.g. refrigerants for which the use of gaskets is not advisable. For these demanding applications FUNKE provides the semi- welded heat exchangers of the FPG- series. These are used as evaporators, condensers or oil coolers in refrigerating, industry, and pro process cooling as well as for special chemical applications.

Design and function

The plates of the FPG - Heat Exchangers base on the proven technology of the FUNKE FP-series. A cassette is made of two corrugated heat exchangers plates which are assemble in a 180 angle to each other. Back to back these are laser welded alongside the SEALING GROOVE PROVIDED FOR THE GASKET. The aggressive medium or the refrigerant runs through the inlet aperture in this now created sealed flow channel between the plates. In the entry zone, the grooves of the plates have a special pattern so that the medium can freely run into the cassette. On the outside, each cassette is fitted with a gasket. When the critical medium passes from one cassette to the other, only two of the four ring gaskets at the apertures get in contact with the medium. These two ring gaskets are made of special high resistant material. To ensure flawless sealing these gaskets in special design are twice as high as conventional gaskets. Furthermore, in the entry zone of the medium the profile of the gaskets are tapered on sealing ring and bridging piece. The flow gap of the less critical medium between the single cassettes is sealed with application- specific gaskets of proven quality. The gaskets are glueless mounted with the absolutely reliable “T- Clip- System”. In the entry zone of each medium double welding seams of the cassettes and double gaskets between the cassettes guarantee for leakage free operation without any danger of mixing of the media.

Material

As standard, FUNKE heat transfer plates are produced in 1.4404/ AISI 316L. Alternatively titanium is available. The thickness of the material is 0.6 mm (other materials on request). For the ring gaskets at the change-over area of the critical medium (as e.g. ammoniac or similar) chloropene gaskets are used. For the flow gap of the uncritical media NBR or EPDM- gaskets are used. Gaskets can also be made of two different materials, i.e. the ring gaskets are made of another material than the main gasket frame (e.g. chloropene for the ring and NBR for the frame)

Fully Welded Heat Exchanger (FPG):

The FunkeBlock FPB and FunkeFlex FPF welded heat exchangers are your perfect solution when it comes to high temperatures and aggressive media. These types of heat exchangers are used, for example, in heat recovery or condensing processes in refi neries, in the chemicals and pharmaceuticals industry and in a wide range of other industries. Thanks to their compact design, with very large heat transfer surfaces, these types of heat exchangers have extremely low space requirements and are also easy to service.

The media used in the heat exchange process are supplied and drained through nozzles installed on the covers (FPF) or casing plates (FPB). The media fl ow through the plate assembly in a cross-fl ow / cross-counter-fl ow pattern, with heat from the hotter medium being transferred to the cooler medium. On account of the turbulent thin-layer fl ow present, this heat transfer is substantially more effective than for other heat transfer models. Baffles can also be employed to ensure that the media pass through the heat transfer process repeatedly.

FunkeFlex FPF

Design and Function

The FunkeFlex FPF is a welded, seal-free plate heat exchanger, whose core consists of a welded plate assembly made of stainless steel. A number of parameters, such as design, dimensions, connections, internals, etc. can be freely selected, or are available as options. This heat exchanger can be used in nearly all sectors of thermal process engineering, thanks to the flexible selection of fl ow path, or different types of plates (Tubular, Chevron and Dimple). With its maximum heat exchange area of 8 000 m² the FunkeFlex satisfi es all the demands for an absolutely versatile heat exchanger.

Technical Data

• max. permissible operating pressure: 40 bar (g)
• min. permissible operating pressure: -1 bar (g)
• max. permissible operating temperature: 600°C
• min. permissible operating temperature: -40°C

FunkeBlock FPB

Design and Function

The FunkeBlock is a welded plate-type heat exchanger with removable, sealed covers whose core consists of a welded plate assembly. Like all items that come into contact with the media, this core is made of stainless steel and, in contrast to the standard casing, can be tailored to meet specifi c demands. The standardized design of the compact FunkeBlock stands out thanks to its fl at cover, its extremely effi cient heat transfer and its high, specifi c heat surface density m² / m³ of free space. A main feature of the FPB is also its ability to be easily cleaned. Using the types of plates available for welded plate assemblies (Tubular, Chevron and Dimple), the demands dictated by the fl ow paths and properties of various media and applications can always be satisfied. Seals can be selected as appropriate, based on their resistance against media or temperatures.

Technical Data

• max. permissible operating pressure: 32 bar (g)
• min. permissible operating pressure: -1 bar (g)
• max. permissible operating temperature: 300°C
