Assuring your success

Would you wear overalls to a cocktail party? Or

turn up in shorts at a board meeting? Certainly

not! Your outfit should always suit the occasion.

It’s no difference with plate heat exchangers.

This is the reason why GEA Ecoflex provides

tailor-made solutions to suit a wide range of

media, demands and production processes:

gasketed plate heat exchangers are the

economic all-rounders

brazed plate heat exchangers are typified

by their compact design and especially

long service life

fully welded plate heat exchangers offer

highest reliability and provide large heat

transfer surfaces.

Plate HeatExchangers

A gasketed plate heat exchanger from

GEA Ecoflex is made up of the following

seven major components:

Support, with certain models, that acts as a

counterpart to the fixed plate and bears the

plate heat exchanger on the opposite side.

Guiding bar, on which, depending on the

model, the plate pack and the loose plate

stand on or are guided by.

Loose plate closes off the plate pack.

Tightening bolts, press the fixed plate and

loose plate together with the plate pack

suspended in between, thus sealing it off.

Carrying beam, on which, depending on the

model, the plate pack and the loose plate are

suspended or guided.

Plate pack, made up of profiled plates with

intermediate gaskets.

Fixed plate, that closes off the plate pack

on the one side and at the same time forms

a load-bearing component of the complete

plate heat exchanger.

The shape of the gaskets between the profiled

plates determines the direction of flow, the flow

opening and the flow gap. Controlled in this way,

the media involved in the heat exchanging

process flow through the plate pack, in turn and

separated from each other.

The performance of the plate heat exchanger

results from the size, pressing structure and

number of the plates installed in series.

The fixed plate is fitted with the inlet and outlet

connections for the liquids involved in the heat

exchanging process. With multiple applications

(internal series connection) of the plate heat

exchanger, connections are also fitted to the

loose plate.

Design and function of gasketed plate heat exchangers

GEA Ecoflex is the direct successor of the company

founded by Eduard Ahlborn that did pioneering

work in 1928 in inventing the plate heat exchanger

and can therefore rely on many years of experience

in the development and manufacture of plate

heat exchangers.

The company headquarters in Sarstedt – located

just outside the trade fair city of Hanover – is in

control of all activities across the globe.

With emphasis on the highest quality standards

and constant innovations, GEA Ecoflex continues

to expand its market position: Within the

GEA Process Equipment Division, GEA Ecoflex

together with GEA Ecobraze, GEA WTT,

GEA PHE Systems North America and

GEA EcoServe forms GEA PHE Systems, the

Center of Competence and Service Center for

gasketed, brazed and fully welded plate heat

exchangers of GEA Group AG.

FlexibilityOur plate heat exchangers can be adapted to

changed performance requirements with a mini-

mum of expenditure. The capacity can be

increased or decreased simply by adding or

reducing the number of plates.

Reduced product contentCompared to conventional units, our plate heat

exchangers have a very small volume, thus

reducing the operating weight, and allowing

quicker start-up and run-down of the complete

system, all to the benefit of your product quality.

Compact designThe higher efficiency of plate heat exchangers

compared to conventional tube bundle heat

exchangers permits a compact design which

facilitates maintenance.

Large selection of materialsEvery single case of application places particular

demands on a plate heat exchanger. We can

equip our units with the widest range materials

for plates, gaskets and frames to exactly suit your

requirements.

Cost savingsWith GEA Ecoflex plate heat exchangers you

save:

investment cost and space in comparison

with other technologies

operating costs thanks to simple main-

tenance and high efficiency.

High heat transfer ratesThe plate shapes developed for the various

applications and the wide range of materials

are the basis for the extremely high heat transfer

coefficients of our plate heat exchangers.

No product mixingThe highly developed gasket design reliably

prevents any mixing of the media involved in the

heat exchange process. The flow opening area is

provided with additional safety by double gaskets

and an intermediate leakage chamber.

Adhesive-free gasketsAdhesive-free gaskets enable a particularly fast

replacement and impressively reduce the time

required until you can restart operation of your

plant.

Your advantages

After moving into the highly modern new Sarstedt

headquarters and putting the two press lines with

15,000 t and 8,000 t press force into operation

in 2003, GEA Ecoflex integrated an automated

30,000 t press in Ystad/Sweden into the production

network in 2006. As early as only one year later,

GEA Ecoflex opened a highly modern factory for

small and medium-size plate heat exchangers in

Puna/India, comprising three flexible press lines

of 2,000 t, 1,000 t and 500 t press force.

By mid-/late 2008, GEA PHE Systems will put

a new factory for all types of plate heat exchangers

into operation in York/USA. With this location

concept, GEA PHE Systems will continue to

stand for innovation and close customer contact

around the globe in the future.

GEAFlexNT

LWC

Free Flow

Concitherm

Varitherm

The NT series sets new economic standards

with low investments costs, operation and

maintenance. The optimised OptiWave plate

design requires less heat transfer surface for

the same performance.

The new EcoLoc and AutoLoc gasket and instal-

lation methods simplify maintenance and ensure

a perfect fit of the gasket and plate packs.

A wide range of possible sizes and shapes

optimises a design to suit the exact operating

requirements. By using special materials, the

NT series can be adapted for special process

needs.

Over 40 different plate types of the Varitherm

series enable an optimisation of just about every

process application where fibre-free liquids

loaded with small particles are involved. Varitherm

has also established itself as a highly efficient

condenser throughout the world.

As with all gasketed plate heat exchangers from

GEA Ecoflex, the Varitherm keeps the investment

and maintenance costs low and can be supplied

in various combinations of materials and sizes.

A classic of perfect manufacturing quality.

Concitherm stands for a series of free flow plate

heat exchangers with the highest performance.

Optimised plate design enables wide flow gaps

with no contact points even with 3 m2 plates.

A low pressure loss in the apparatus means that

there is scarcely any need for an intermediate

pump. In contrast to conventional tube evaporators,

Concitherm offers an almost 100% higher heat

transfer value.

Concitherm plate evaporators can also be com-

bined as boosters with conventional evaporators.

GEA Ecoflex Free Flow systems are suitable for

products containing solids, crystals, fibres and

pulp, as well as for highly viscous media.

A coarse-waved pressing structure specially

developed for these media means that the plates

are not susceptible to soiling. Up to 12 mm wide

flow channels with no contact points prevent

blockages.

For special applications both wide and narrow

flow gaps can be combined in a Free Flow system.

Critical media limit the usage of plate heat ex-

changers fitted with conventional gaskets.

GEA Ecoflex can offer a technological alternative:

the LWC plate heat exchanger made of Laser

Welded Cassettes. These cassettes are fitted with

gaskets only in the flow opening area. The special

gaskets are resistant to most aggressive media.

The successful OptiWave design of the NT range

is also used in the LWCs and guarantees efficient

heat transfer.

Gasket materials

GEAFlex plate heat exchangers are perfectly

suitable for gaseous, liquid and two-phase media

in the chemical and petrochemical industries.

Temperatures from minus 200 °C to plus 900 °C

as well as pressure ranges of up to 60 bars are no

problem. The asymmetrical plate design and the

innovative tube and ripple embossing ensure

heat transfer with maximum efficiency while

keeping pressure losses low. Freely selectable

pressure-bearing housings and connecting lines

enable configurations of tailor-made GEAFlex

plate heat exchangers with a installed heating

surface area of up to 8000 m2. Its compact design

requires less material, resulting in lower invest-

ment costs, that are especially noticeable when

using high-quality alloys.

REKUGAVO and REKULUVO (from the

German “Rekuperativer Gasvorwärmer”, i.e.

“Recuparative gas preheater”and “Rekuperativer

Luftvorwärmer”, i.e.“Recuparative air preheater”

respectively) are the names given to our fully

welded specialists for gaseous media. The units

achieve exceptionally high heat recovery rates

using the countercurrent principle.

REKULUVO is particularly suited for preheating

combustion air, for example in petrochemical

plants.

REKUGAVO is the perfect heat exchanger for

heating up flue gas to the catalytic reaction

temperature, for example in desulphurisation

units of refuse incineration plants.

PHE by GEA Ecobraze, GEA WTT and GEA PHE

Systems North America, our affiliate companies

in Sweden, Thuringia / Germany and the USA,

are brazed in vacuum with copper or nickel.

Especially compact, space-saving, and gasket-free

they fit many applications that gasketed PHE

cannot serve. The extensive product range offers

solutions for a broad range of applications.

GEAShell – an extremely reliable, fully welded

plate heat exchanger that proves its superiority

where other heat exchangers reach their limits:

At temperatures between minus 200 °C and plus

950 °C and at extreme operating pressures.

The heat transfer area of a GEAShell consists of

many profiled stainless steel plates which are

welded together to form a plate pack and are

precisely fixed in a shell tube. After fitting the

connections, the shell tube is completely welded.

Each GEAShell is manufactured individually and

optimized according to the customer’s wishes.

The material and the position of the shell side

connections may be defined as required.

REKUGAVO/ REKULUVO

No system is stronger than its weakest compo-

nent. This is why GEA Ecoflex is constantly

working on the innovation of the gasket

engineering in gasketed plate heat exchangers.

We have optimised gaskets made of the following

materials to suit the different applications:

NBR, nitrile rubber, stable to 140 °C

Butyl, butyl rubber, stable to 140 °C

EPDM, ethylene/propylene rubber,

resistant to 170 °C

Silicone rubber, resistant to 175 °C

Viton, resistant to 180 °C

Hypalon, resistant to 140 °C

Neoprene, resistant to 90 °C.

The stated temperature limits apply for

water/water applications.
