Editorial

GEA Batignolles Technologies Thermiques has more

than 50 years o experience designing heat exchangers:

dry aircooled condensers, humidiied aircooled rerige-

rant, vacuum steam condensers. GEA BTT oers you a

reliable and strong support to operate and maintain your

heat exchangers with two structures: in-house Customer

Support Services department; and its subsidiary service

company GEA Airlow Services.

GEA BTT provides spare parts and services or all kinds

o aircooled heat exchangers, GEA BTT is able to perorm

re-engineering o sub-elements and parts designed by

other OEM, designed and manuactured several decadesago. GEA BTT serves you through its network o 3 acto-

ries (France, Qatar and China), 1 service company and

more than 20 distributors worldwide.

GEA BTT perorms thermal re-sizing o existing exchan-

gers, using latest versions and developments o design

proprietary sotware. GEA BTT does mechanical re-

rating, re-designing to adapt heat exchangers to the new

processes, new directives and latest amendments o inter-

national laws.

GEA Airlow Services perorms aircooled heat exchan-

gers assessments on GEA BTT heat exchangers, and other

abricators heat exchangers as well. GEA AFS modiies

existing heat exchangers to cope with more perormance,

extra output.

Exploring GEA BTT spare parts catalogue which des-

cribes the complete range o our spare parts oers, you

will see rotating parts, gaskets and sealing, inned tubes,

inned tubes bundles, tools or maintenance and setting.

Tube bundles

With more than 42 000 bundles manuactured since 1958,

GEA BTT is your best partner to replace your bundles.

From the simplest carbon steel bundle to the most complex alloy

steel or titanium bundle, we meet your requirements or any

bundle replacement or bundle upgrade. GEA BTT can design &

manuacture new bundles with your new thermal conditions.

Maximum speciication:

width: 4.2 meters

length: 19 meters (with 60 eet long tubes)

pressure: 500 bar

We manuacture bundles or all kinds o services (hydrogen, H2S,

wet H2S / sour, lethal, toxic, CO2, cyclic, amine, ...).

We can replace one or various parts o your bundle.

HeadersCore component o the air coolers, the header design and

manuacturing is the GEA BTT speciality.

We use all kinds o welding method (GTAW, GMAW,

electron beam welding ...), heat treatments and coatings.

GEA BTT is also approved or headers & bundles repairs(ASME R-STAMP).

Plug header

Cover plate header

Pipe header

The plug header is suitable or working pressure up to 350 bar. The

plug hole opposite each tube allows expansion o the tube in the tube

sheet,mechanicalcleaning,and pluggingin caseof leakage. In case

o high partial hydrogen pressure, tube attachments can be sealed orstrength welded through the plug hole.

The cover plate header is used or uids with high ouling actors, up

to 40 bar maximum when a requent mechanical cleaning is necessary.

They are used or very corrosive uids to periodically check the corro-

sion allowance.

The pipe header is used or working pressures over 200 bar when no

inner access is necessary. Finned tubes hair pins are assembled with

TIGbuttweld.WeldscanbethermallytreatedandX-rayedifneeded.

Welded bonnet header

The welded bonnet header is used or condensers and vacuum steam

condensers. The advantage is the ull welded construction, perectly

sealed. The tube sheets are directly welded to the maniold.

D type header

A large circular maniold is used when the allowable pressure drop is

very low. This large maniold ensures an equal distribution o uid

ow in the tubes. This type is used or vacuum steam condensers and

rerigeration units.

Tube diameters: 1, 1 , 1, 2

Fins pitch: 8 to 11 ins per inch

The heat transer surace o air-cooled heat exchangers is extended

using aluminum spiral fns. The thermal conductivity o this material is

efcient. Moreover the purchasing and conversion costs are competitive.

The in consists o an aluminium strip, which is tension-wrapped and embedded into the core tube wall. This results rom the combined

action o a set o tools. Operating sequences are as ollows:

thefirstdisc(groover)spinsagrooveintothetubewall

theringspacerleadsthestripfoot-edgeintothegroove

finallytheseconddisc(backfiller)firmlyembedsthestripfoot-edgeintothegroovebycaulkingthegroovelip

The aluminium strip oot section is frst ormed into a double L-stepped shape. This results in a fn base twice as large as that o a single L-

shape. The LL-fn strip is then wrapped onto the primary tube so as to obtain an overlap on the 1st stepping o the LL-shaped fn. A continuous

and double strip cover against corrosive environment then efciently protects the primary tube.

An aluminium strip is olded to orm an L-shape and then wound around the base tube. The eet o the ins are joined together so as to

ensure a continuous cover on the primary tube surace. The whole width o the oot o the in is knurled simultaneously with the inner

tube, thus ensuring a tight contact between the spiral in and the primary tube.

A core tube, careully degreased, is itted into an aluminium sleeve. This tube-in-tube assembly is then ed into the inning machine equip-

ped with three spindles , spaced 120 degrees and each itted with a gang disc. These discs, which are stepped in proile and diameter, will irst

extrude and shape the in, and then bond it to the core tube. GEA Batignolles Technologies Thermiques has developed a high perormance

HumidiferThe humidiier system is mostly used in hot and dry climate

countries when ambient air temperature and product tempera-

ture are too close.

Water droplets are used to reduce ambient air temperature. Then,

the inlet air low is dried through mist elimination blades in order

to avoid inned tubes corrosion.

Fogging system (peak cooling)A ogging system (peak cooling) can be deined as a

serie o misting nozzles that are placed in a tubing and

pressurized to provide a ine spray, usually with droplets

between 15 microns and 50 microns in size. To accom-

plish this, the mist system requires pressure o at least

50Bar(725PSI).

The principle is based on the cooling o the air at a

temperature close to its temperature o adiabatic satu-

ration per water evaporation. Depending on climatic

environment, a properly designed ogging system can

decrease the inlet air temperature by as much as 12C

(54F) which in turn increases considerably your cooling

capacity.

Cleaning

Semi automatic HP cleaning machine

A flat razor-blade sharp water beam is used to remove fouling

from between the fins.

This cleaning process uses only water, no chemicals.

Water pressure is 80 100 bar, low 150 or 300 l/min.

By using the correct nozzle angles the water beam penetrates

between the ins o all tube rows.

The nozzle beam is moved over the bundles by pneumatic or elec-

tric drives, avoiding operators standing on the coolers.

Cleaning can be done during operation.

The cleaning unit is a light weight construction to be positioned

on top o the bundles or on rails installed on the cooler bundles.One cleaning system can handle 2 - 4 air coolers in one day shit.

Obstructions like louvers can be dealt with by installing rails

between the bundle rame and the louvers.

The cleaning-water can be collected and reused ater cleaning.
