Top performance made to measure

Fully Welded Plate Heat Exchangers

Powerful, compact, economical

Our fully welded plate heat exchangers’ major selling

points are their compact size, outstanding heat-transfer

coeffi cients and comparatively low capital cost. They

are particularly robust and easy to clean and maintain.

The advantages in structural design are therefore

especially effective in fi elds where load capacity is

called for as well as performance. Each model series has

its own special advantages and fi elds of application.

GEAShell

GEAShell is a fully welded plate heat exchanger which

satisfi es 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 pressu-

re 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 industry, refrigeration and

power generation, the chemical industry and in marine

applications GEAShell is confi gured so as to accord with

technical requirements and at the same time minimise

capital outlay and running costs.

GEAFlex

Solves many problems: the fully welded GEAFlex

The GEAFlex is manufactured to customer require-

ments. The fully welded plate heat exchanger makes

installations with a heating surface of up to 8000 m2

possible. Its asymmetric plate design and special tube

and corrugation pattern make the GEAFlex a popular

choice for handling two-phase fl ows. The ideal applica-

tions for the GEAFlex are in condensation and evapora-

tion and for handling markedly different primary and

secondary volumetric fl ow rates. The asymmetric plate

design yields very effi cient heat transfer, the tubular

fl ow area keeping pressure losses small.

There are hardly any limits to the plate pack’s incorpo-

ration 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

comparatively low capital costs and high economic effi -

ciency. The GEAFlex is suitable for gaseous, liquid and

two-phase media in the chemical and petrochemical

industries and many other areas of application.

GEABloc

Standard yet customized to 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 positioned at 90° to the adjacent one

and welded, the channels formed differing depending

on the plate profi le.

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 baffl e plates enable the heat exchanger to be

adapted to its operating points.

The GEABloc works at temperatures up to 315 °C and

pressures up to 32 bar. Its principal uses are in the oil/

gas industry, the petrochemical and chemical industries,

the motor industry, the pharmaceutical industry and

also in papermaking.

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

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

REKULUVO/REKUGAVO

Top performance for air and gas

Wherever especially high-performance waste-air

or waste-gas heat exchangers are needed

REKULUVO/ REKUGAVO are employed, e.g. to

preheat inducted combustion air or to heat fl ue

gases to a catalyst’s reaction temperature.

By applying the counterfl ow principle

REKULUVO/REKUGAVO attains an exceptionally

high effi ciency factor of up to 97%. It is used for

example in environmental technology, in ammonia

and methanol plants and in thermal power plants.
