The short story
The company C.C.Jensen
1953- 2003
C.C.Jensen A/S - a Danish industrial
The growth layer of Danish industry largely consists of small and medium sized
companies. Most of them family-owned like C.C.Jensen A/S.
There are several obvious advantages to family companies: a short line of command
and quick adjustment to changing conditions. More often that not the
family company is characterized by a strong sense of responsibility: they care for
their employees and customers, almost as were they family members. That was
true for C.C.Jensen in 1953, just as it is for C.C.Jensen A/S today.
The CCJ spirit
The financial policy is a cornerstone of the company’s sense of responsibility.
The principle of economical responsibility was also founded in the years after
1953 when Mrs. Karen Jensen managed both the company’s bookkeeping and
the household accounts. In the beginning the two sets of accounts were virtually
the same. Invoices from the growing filter production, bills concerning purchase
of clothes for the children, bills from the groceries store and many other private
expenses were meticulously archived in cardboard boxes with handwritten titles.
It is in these boxes we find the beginning of the story of C.C.Jensen.

The good story
One day, towards the end of the
1930's, onboard m/v Marchen
Maersk travelling from America
to Japan, the first assistant
engineer made his rounds in the
engine room. For some time he
had kept a watchful eye on oil
drops leaking from a pipe connection
in the engine’s lube-oil
system. On this particular day
he observed them very closely
and incidentally a drop fell on
his hand. Looking at the drop
he could not help noticing how
clear is was. Intriguing, because
he knew that the oil flowing in
the pipes was pitch dark from
soot and blow-bys. He took a
closer look and saw that the
drop had been pressed out
Chapter I
The History
through the gasket in the flangeassembly
of the pipes. His
immediate thought was that the
gasket material had acted as - a
filter!
Roughly so, we imagine, were
the circumstances inspiring
marine engineer C.C.Jensen to
develop a filter for the lubrication
oil in the ship’s diesel engine.
The facts are that he sailed on
five different Maersk vessels
from 1930 to 1937 and that his
idea saw the light of day during
this period. He did not himself
make a note of that particular
incident, but he must have told
it to someone, because the
story is still told in the company,
and very often in more dramatic
versions with the oil drop hitting
him right on his nose and
making him an inventor in that
very moment. And maybe that
was what happened - who
knows?
Before we in the following begin
the ascertainable story of the
company of C.C.Jensen, we
must remember that at the time
great inventions were often the
work of a single man - and not
like today, where inventions
more often than not are the
result of intense teamwork.
The true story
The inventor of the CJC Fine
Filter and the founder of the
company C.C.Jensen, Carl

Christian Jensen, was born in
1906. Already at the age of 13
he took lessons in mechanical
drawing and in 1921 he started
as an engineering apprentice.
He and his family now lived in
Svendborg and the largest and
most complex factory in town
became his workplace, namely
Svendborg Steel Shipyard. His
future course had been charted.
The Marine Engineer
The shipyard, established in
1907, had in 1919 undergone
an extensive modernisation and
was now a modern, industrial
company which, as customary
at the time, comprised virtually
all trades and professions. In
other words: a well of knowledge
to the inquisitive. That he
would later return to the shipyard
in another position and the
yard would play an important
role during the start of his own
company, he did not know
then.
After six years’ apprenticeship
he finished as a trained machine
room operator in 1927 and was
able to sign up for a ship. He
had already been in contact
with the shipping company
A.P.Moeller so that same year
he was hired for the first in a
row of Maersk vessels. His first
vessel was a steamer, s/s Hans
Maersk (1916), which he signed
on to in Naples.
The sailor and the diesel
engine
1930 saw the beginning of the
most important part of his sailing
career. That was when he
signed on to his first motor ship,
the m/v Marie Maersk, as third
assistant engineer. From his letters
home we learn that this
ship meant a considerable
improvement to his working
conditions - and it must have
meant the world to him that he
now worked with diesel engines
- an almost virgin technology in
seagoing vessels at the time.
This was just 18 years after the
first ocean going diesel-propelled
vessel, m/s Selandia had
returned to Denmark after her
maiden voyage.
M/v Marchen Maersk,
one of the five Maersk vessels
C.C.Jensen was signed on to.

Chapter II
The Present
Right now…
When looking back in time as
we have just done, it becomes
clear how the C.C.Jensen A/S
of today is the inevitable result
of its history and the people in
it. One may claim that everything
is a result of its history, but
in the present decade, where
“branding” is the stated strategic
objective of many companies,
it is comforting to see that
the values represented by the
CJC brand are the result of a
natural development of the
company.
Branding is not only a question
of getting your name and trademark
known. If the existing
customers are to remain custo-
mers - and if a company wants
to win new customers - its
products and trademark must
not only be known, but renown.
It is all about consistent quality
and confidence; confidence in
the products as well as in the
organisation behind. Confidence
is something you earn - and
usually over a long period of
time. When the C.C.Jensen
sales people and representatives
move in the fast-running
world of today to sell the company’s
products to new markets,
new customers or new
applications, they obviously do
not have long time to earn the
confidence. Consequently, it
becomes very important that
their self-confidence is impecca-
ble - and there is no better
basis for self-confidence than a
solid foundation in company
history.
SALES & APPLICATIONS
To illustrate both the diversity of
the CJC products and the challenges
presented to CCJ sales
people, we will take a closer
look at some of the important
CCJ customer segments and filtration
applications.
Mining
Although C.C.Jensen has supplied
filtration equipment to
mining machinery (crushers,
excavators, etc.) the real breakthrough
came not too long ago
in Chile as the result of a very

dedicated effort by CCJ’s young
subsidiary in that country. They
had targeted the big Chilean
copper mines as potential CJC
customers, starting out with
small off-line filter units for various
mobile machinery. However,
the big tractors, trucks, excavators
etc. are not owned by the
mine, but leased from the
manufacturer, the large
American company Caterpillar,
who is also responsible for all
maintenance. The oil for the
equipment was to be supplied
by the mine, who had made an
arrangement with Esso Chile,
who had established large oil
storage facilities at the mine.
Three parties with each their
particular interest.
It took some work and quite
some time to convince the three
parties that they had a mutual
interest in improving the oil cleanliness
of the oil for the machines,
but in the end CJC Filters
were installed on the large storage
tanks and mobile filter units
are used whenever the big mobile
machines are serviced - and
most of the stationary machines
have been equipped with CJC
Filters as well. It goes without
saying that in a harsh environment
as mining with heavy duty
use, loads of dust and extreme
temperatures, a stringent and
continuous control of oil cleanliness
is of utmost importance. As
such, the mining industry constitutes
an application sector very
interesting to CCJ; the fine filtration,
the water separation, the
huge dirt holding capacity, the
modular build and customized
designs, and not least the deep
knowledge of oil maintenance -
all the CJC virtues are called for
in the mining industry.
As a spin-off, the Chilean project
lead to the introduction of
higher oil cleanliness standards
within the entire mining area and
CCJ is now cooperating with
Caterpillar, the oil companies,
the storage designer and the
mines to improve the oil storage
plants. And other CJC distributors
around the world are already
benefitting from the experience
gathered in Chile.

Klassen Speciality
Hydraulics has successfully
sold and serviced many
CJC products to a variety of
applications within the
paper industry. Seeing
Harvey Klassen in front of
the paper machine gives an
excellent impression of how
huge these machines are.
Pulp & paper industry
C.C.Jensen A/S has a long
history of supplying filtration
equipment for paper machines.
Around 1980 when the company
had founded an in-house
sales department, the first
export market to be taken on
was Sweden - a country with a
huge pulp and paper industry.
Virtually all prime processes in
paper manufacture involves
water. Particularly the huge
paper machines where the pulp
(basically cellulose fibres blended
in water) is band pressed
into big lanes of raw-paper, are
prone to have their lubrication oil
polluted with water.
Consequently, the first Swedish
CJC importer and their salesman,
Birger Vesterlund, saw a
huge potential for the CJC Filter
Separator in this segment - and
after a solid and long effort he
succeeded and his work was a
real boost for the use of large
CJC Filter Separators in industrial
applications (the Filter Separator
was originally developed for
the fine filtration and water separation
on marine diesel fuels).
The contact with the Swedish
paper industry also played an
important role in the development
of the CJC Desorber. In
the very large central lubrication
systems of paper machines the
water ingress rate is often so
high that a conventional CJC
Filter Separator would have to
be extensively large to keep
pace. Further, the lube oils used
in paper machines often have a
tendency (inherent or through
wear) to dissolve large amounts
of water. CJC Filter Separators
cannot separate dissolved

water from oil, so a more
“powerful” method had to be
found. The answer C.C.Jensen
came up with was desorption: a
process where water is removed
by blowing cool, dry air
through the warm oil and the air
“absorbs” the water. It would be
wrong to say that the CJC
Desorber was a hit right from
the start, but as so often before
a constructive cooperation between
a customer and
C.C.Jensen resulted in a valuable
and viable solution. CJC
Desorbers now consist of a
range of types and models and
the utilization of the desorption
principle is still somewhat of a
C.C.Jensen speciality.
Today not only CJC Filter
Separators and Desorbers are
sold to the pulp and paper industry.
The CJC products find use
on a variety of applications:
paper machines, defibrators,
slap presses, refiners and bearing
systems a.m.o. - and in
almost all of the important paper
manufacturing countries in the
world.
Steel industry
Heavy industries such as steel
production and milling are ideal
CJC application areas. Tough
operating conditions with heat,
dust, dirt and cooling water
enhances the need for high
quality oil filtration solutions and
the vast dirt holding capacity of
the CJC Filter Inserts is a valuable
sales argument. The history
of CJC products in the steel
industry goes back to the late
1950's when C.C.Jensen’s
German licensees, Karberg &
Hennemann began selling Fine

Filters to the large, German steel
manufactures. When C.C.Jensen
established its own sales department
the existing leads to the
steel industries were inspiration
to address similar customers in
other countries.
Over the years CCJ have supplied
oil filtration solutions for many
types of mills and machinery within
the steel and related industries,
mainly in European countries
such as Great Britain, Sweden
and Germany. Heavy industries
in general is an important market
segment to C.C.Jensen. As
mentioned in the story of the
Chilean mines sales above,
heavy industry applications
often require special solutions,
customized and combined oil
maintenance units. In brief, this
an area where C.C.Jensens vast
knowledge of filtration combined
with the versatility of the entire
range of CJC products have
proved to be very efficient.
Power generation
industry
Some of the biggest CJC Filter
Separator units ever made have
been supplied for maintaining
the main lube oil on large power
generation steam turbines. The
CCJ organisation is in constant
contact with the world’s major
turbine manufacture and have
frequently supplied oil maintenance
equipment for new power
plant projects.
The use of CJC Filters within
power generation dates back to
the very start of the company
C.C.Jensen - yes, even a few
year before the start. As mentioned
earlier in this book some of
the very first CJC Fine Filters
were tested and sold to local
Danish power plants. Back then
the “plants” were not that big
and almost all of them had diesel
powered generators, and the
CJC Filter was used for cleaning
the lube oil on these diesel engines.
The later experiences from
Germany with CJC Fine Filter
units for turbine lube oil and not
least from Sweden, where a
great number of CJC products
have been supplied for a variety
of hydro turbine power genera-

tion related applications, have
given C.C.Jensen a good insight
in power generation technology
and requirements.
The use of isolating oil is a
quite specialized application
within power generation and
distribution. Because of its
electric isolating and coolant
properties of certain types of
oil, large industrial electric
switch gears and transformers
are oil filled. For an number of
years C.C.Jensen has supplied
filtration solutions for switch
gears and on-load tap changers
- even as original equipment
to some manufacturers.
In order to preserve the isolating
and lubricating ability of the

oil it is in switch gears important
to continuously remove the
many particles deriving from
the hard metal-to-metal contact
and sparking between the
metal surfaces - and also to
keep the humidity (water content)
of the oil very low.
Keeping the oil almost completely
dry is even more important
in power transformers. The presence
of water and oxygen in
the isolating oil may dramatically
reduce the lifetime of a transformer
as they accelerate the
degradation of the oil and, not
least, the paper isolation material
in the transformer.
With an ambition of being a fullscale
filtration provider to the
power industry, it was only natural
when C.C.Jensen a few
years ago started developing a
dedicated transformer oil maintenance
unit. In many ways the
resulting product, the CJC
Vacuum Filter, represents a step
into a new world for CCJ. The
Vacuum Filter combines a well
known filtration method, the
depth filter insert, with a new (to
CCJ) technology: vacuum - the
ideal method to remove even
the slightest (water) humidity
from oil and a fine supplement
to the water removal technologies
already mastered by CCJ,
namely coalescing, absorption
and desorption.
Further, the oil chemistry of
transformers is quite different to
the traditional CJC applications:
lubricating and power transmitting
oils, so for the CCJ organisation
to acquire the necessary
knowledge of transformer technology,
manufactures markets
and customers has been a challenge,
yet a rewarding one. It
has brought the company pro-
duct developments and insight
from which not only the entire
organisation, but also the traditional
CJC products will benefit
for years to come.
Wind turbines
Even though wind turbines -
along with other renewable
energy sources - strictly speaking
is part of the power generating
industry, they deserve
specific mentioning in this
account of CJC application
areas. Around the turn of the
century the state of the art wind
turbines had become so large
that the extreme load on their
gearboxes called for improved
oil maintenance. C.C.Jensen
had the good fortune to have
three of worlds major wind turbine
manufactures on the Danish
home market, so it was only
natural for the company to seize
this excellent opportunity to

combine forces with the turbine
manufactures in developing a
CJC Off-line Fine Filter solution
especially for wind turbine gearboxes.
Obviously, success did
not come overnight - but it
came! Through a dedicated,
serious effort and a continuous
exchange of experience and
knowledge with the manufacturers
CCJ has sold more than
15,000 Fine Filters to wind turbines
worldwide during the last 6
years.
This would not have been possible
without a coordinated
sales and marketing work in the
almost entire CCJ distribution
channel, where both wind turbine
manufactures and the after
market have been targeted. The
wind turbine adventure has
taught the CCJ organisation the
value of world wide knowledge
sharing and joint efforts.

electronics will be available for
more CJC products - and
C.C.Jensen will allocate considerable
resources to the research
of sensoring and analysis
technologies
The sharing of knowledge and
competent technical back-up
are key elements in
C.C.Jensen’s strategy for the
future. We want CJC sales
people to be the most competent
within their field and we
want our engineers and product
specialist to be on the forefront
of filtration technology development.
The primary tools to
achieve these ambitious objectives
are extensive training and
the utilization of information
technology. Within the frame-

work of the CJC Univers we
arrange practical and theoretical
training lessons, both for the
Danish based C.C.Jensen personnel
and for sales people and
technicians from the sales organisation
worldwide.
With the use of information and
communication technology
C.C.Jensen is able to offer training
sessions as e-learning and
able to share knowledge in virtual
real time - and we will both
broaden and deepen our know-
ledge through networking with
relevant organisations and research
institutes. And we will do
this to continue to be able to
provide our customers with the

The CCJ success on the
wind turbine market meant
a huge challenge to the
Danish filter manufacturing
departments. They had to
increase production of certain
filter models by a factor
of five in very short time -
and they did it! Having
excelled under such pressure
makes one proud and
happy - and ready to take
on future challenges.
