Top performance made to measureWithin the Process Equipment Division of the inter-

national GEA Group, GEA PHE Systems is the center

of competence for plate heat exchanger technology.

Strong individual companies – GEA Ecoflex for

gasketed and fully welded plate heat exchangers,

GEA Ecobraze and GEA WTT for brazed plate

heat exchangers – provide customer-specific solu-

tions for just about every application. GEA EcoServe,

the GEA PHE Systems service organization, offers

quick and competent maintenance and spare parts

service through service centers in many countries.

Alongside our gasketed and brazed product lines

we now additionally offer you a complete range of

individually configured fully welded plate heat

exchangers of various types, which can be employed

wherever critical media or extreme working

temperatures and pressures make particularly high

demands:

· GEAShell

· GEAFlex

· GEABloc

· REKULUVO/REKUGAVO

Our fully welded plate heat exchangers’ major

selling points are their compact size, outstanding

heat-transfer coefficients and comparatively low

capital cost. They are particularly robust and

Applications

Extremely reliable

GEAShell is a fully welded plate heat exchanger

which satisfies very exacting requirements in

relation to process reliability. The heat exchanger

plates designed for individual solutions are

welded into a pack and mounted in the fully

welded pressure vessel. This design principle

ensures that the exchanger is both highly

resistant to pressure and temperature and also

leak-tight. Media are fed in through ports on

the pressure vessel, the ports’ position being

determined by customer requirements.

GEAShell is rated for extreme temperatures

of – 200 °C to + 950 °C and operating pressures

of up to 100 bar. For use in the process indu-

stry, refrigeration and power generation, the

chemical industry and in marine applications

GEAShell is configured so as to accord with

technical requirements and at the same time

minimise capital outlay and running costs.

popular choice for handling two-phase flows.

The ideal applications for the GEAFlex are in

condensation and evaporation and for handling

markedly different primary and secondary

volumetric flow rates. The asymmetric plate

design yields very efficient heat transfer, the

tubular flow area keeping pressure losses small.

There are hardly any limits to the plate pack’s

incorporation in any type of pressure-resistant

casing. Many problems in thermal process

engineering can be solved by using the GEAFlex

– temperatures of – 200 °C and + 900 °C and

pressure ranges up to 60 bar are handled, for

example. It is at the same time distinguished by

GEABloc

Standard yet customizedto your needs

GEABloc is a fully welded frame-mounted

plate heat exchanger in which two different

types of plate may be used. Each plate is posi-

tioned at 90° to the adjacent one and welded,

the channels formed differing depending on

the plate profile.

The frame consists of four columns, a base

plate and a top plate together with four side

panels with ports. All frame components are

bolted together and can be easily dismantled

to clean and inspect the plate pack. Adjustable

baffle plates enable the heat exchanger to be

adapted to its operating points. The GEABloc

works at temperatures up to 315 °C and pres-

sures up to 32 bar. Its principal uses are in the

oil/gas industry, the petrochemical and

Available in different patterns and sizes for a wide variety of applications, including replacement of existing systems.

All media-contacting components are made from high-grade alloys or materials. The bolted frame provides easy access for

maintenance and cleaning.

the pharmaceutical industry and also in
