Semi-welded plate heat exchangers 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 appli-

cations FUNKE provides the semi-welded heat exchangers

of the FPG-series. These are used as evaporators, con-

densers or oil coolers in refrigerating, industry-, and pro-

cess cooling as well as for special chemical applications.

Design and functionThe Plates of the FPG-Heat Exchangers base on the prov-en technology of the FUNKE FP-series. A cassette is made

of two corrugated heat exchanger plates which are assem-

bledin a 180 angle to each other. Back to back these arelaser welded alongside the sealing groove provided forthe gasket. The aggressive medium or the refrigerant runsthrough the inlet aperture in this now created sealed flowchannel between the plates. In the entry zone, the groovesof the plates have a special pattern so that the medium canfreely run into the cassette.

On the outside, each cassette is fitted with a gasket. Whenthe critical medium passes from one cassette to the other,only two of the four ring gaskets at the apertures get incontact with the medium. These two ring gaskets are made

of a special high resistant material. To ensure flawlesssealing these gaskets in special design are twice as highas conventional gaskets. Furthermore, in the entry zone ofthe medium the profile of the gaskets are tapered on seal-ing ring and bridging piece.

FUNKE is a leader in the development and production of quality heat exchangers with a heat transfer area of

up to 2400 m. The range of products comprises shell-and-tube heat exchangers, bolted and brazed plate heat

exchangers as well as oil/air cooling units and electrical oil pre-heaters. Thus, as one of the few producers

worldwide, FUNKE offers solutions with optimum thermodynamic designs for different industries and virtually all

applications.

FUNKE focuses on customer orientation, highest quality standards, flexibility and advisory skills important

benefits a company of just the right size is able to offer.

With partnership

into the future

The flow gap of the less critical medium between the singlecassettes is sealed with application-specific gaskets ofproven quality. The gaskets are glueless mounted with theabsolutely reliable T-Clip-System.

FPG semi-welded plates

In the entry zone of each medium double welding seams ofthe cassettes and double gaskets between the cassettesguarantee for leakage free operation without any danger ofmixing of the media.

Advantages Very flexible system. The Adaption of the heat exchanger

to new operating conditions is feasible any time by ex-changing or adding components.

Facile cleaning of gasketed exchanging surface. Low soiling tendency. Fast and ecomomic mounting. High heat transfer coefficient. Extreme corrosion resistance. Uncomplicated changing of gaskets (combined gasket

frame).

MaterialAs standard, FUNKE heat transfer plates are produced in1.4404/AISI 316L. Alternatively titanium is available. Thethickness of the material is 0.6 mm (other materials onrequest).

For the ring gaskets at the change-over area of the criticalmedium (as e.g. ammoniac or similar) chloropene gasketsare used. For the flow gap of the uncritical media NBR orEPDM-gaskets are used.

Combined gaskets:

Gaskets made of two different materials,

i.e. the ring gaskets are made of anothermaterial than the main gasket frame

(e.g. chloropene for the ring and NBR

for the frame)
