Certifications
All product processes of GEA Renzmann & Grnewald
are due to the strict standards of national and international modern quality control systems like DIN ISO 9001,
-Norm 7812 or ASME-Codes U1 and UM (U-stamp
and UM-stamp).
As a standard, the compact heat exchangers are
designed according to the following directives:
Pressure Vessel Regulation (valid until May 29,2002)
with and without TV inspection/AD Merkbltter
CEE Directive 97/23/EG
with CE-marking/AD Merkbltter
Upon request the heat exchangers also
can be dimensioned by constructional
alteration accordingto following standards:
ASME

Example 1:
Water preheater, completely made
of stainless steel 1.4541
thermal capacity: 58.26 kW.
Size KM 125/8
Pressure loss Tube Side 51mbar
Shell Side 337 mbar
Size KM 150/8
Pressure loss Tube Side 21mbar
Shell Side 272mbar
Size KM 200/10
5.562 kg/s water is heated from

Example 2:
Compressed air cooler, thermal
capacity: 3.9 KW. The diameter
for the head flange and the shell
is identical for sizes 65 and 100.
Size KM 65/10
Pressure loss Tube Side 67 mbar
Shell Side 66 mbar
Size KM 100/10
Pressure loss Tube Side 11mbar
Shell Side 13 mbar
Size KM 125/10
Pressure loss Tube Side 4 mbar
Shell Side 49 mbar
Example 3:
Motor water cooler, thermal
capacity: 640 KW. Due to the large
quantity of motor cooling water
involved, a design has been chosen
in which the water flows through
the tubes.
Size KM 200/10
Pressure loss Tube Side 30 mbar
Shell Side 350 mbar
Size KM 250/10
Pressure loss Tube Side 12 mbar
Shell Side 240 mbar
Size KM 250/8
13.9 kg/s motor water with 30% glycol cooled
from 90 auf 78C by service water,
which in turn heats up from 60 to 75C.

Tube Cleaning
GEA Renzmann & Grnewald offers its own proven
cleaner for the tube side of the cooling tubes.
The tube cleaner consists of a cleaning tool - a cage attached to a pipe of suitable length for the tube bundle
to be cleaned. The pipe is provided with a hose
connection and a handle. During the cleaning operation, the spiral wire coils effectively scrape off the dirt,
which is than washed away with water introduced
through wash nozzles.
