n the 3rd of March 1909 LUIGI BOLDROCCHI established
the activity with the first orders for the supply of ten
centrifugal fans.
In 1911 the Officine Termo Meccaniche BOLDROCCHI
was set up in Milano with an operating area of 3000 square meters.
In 1914 the first plant for air pollution control was produced.
The company offered a wide range of products including radial and axial
fans, fire-tube boilers, coolers, dryers, ventilating and heat-exchange units
and plants.
In 1926, the licence for the manufacture of finned tubes was acquired in
the USA and the manufacture of extended surface heat-exchangers was
developed.
In the twenties and thirties the company becomes a regular supplier of the
main Italian industrial groups, the Ministry of Defence, naval yards and
State Railways.
The first air conditioning equipments for industrial and civil use were
developed; important supplies were installed in the Scala Theatre in Milan,
in the Parliament in Rome and in the first Submarines.
In the postwar period, the activity was carried on by

GIULIANO BOLDROCCHI who progressively abandoned standard
production to concentrate on tailor made equipment for specific
industrial fields such as: power generation, the electromechanical
industry and major shipbuilders.
In 1970, a new factory was built and, with some later extensions,
forms the present site.
In 1972, under the licence of the Swedish company, BAHCO,
the production of industrial dedusting plants was increased.
In the early eighties, supplies for the nuclear sector induced the
company to introduce a Quality Assurance System.
From then on, the product range has been enlarged, particularly
for air coolers and steam condensers.
In the environmental field, two independent divisions have
been established:
Aeroto, part of the group since 1994 keeps the original
name of the company Aeroto, active since 1952 in industrial
noise protection and gas turbine ancillaries.
Ecologia, a fusion of our traditional technology with the
expertise of De Cardenas, purchased in 1997 and active since
1926 in air pollution control and industrial fans.
Completing our own structure and know-how with those ones
of De Cardenas and Marelli Ventilazione, Boldrocchi has
become the heavy-duty fan leader in Italy.
T
he Boldrocchi group now comprises various companies in
the world that can offer solutions for different production lines.
The group employs 300 people, 150 of which work in
production. The Biassono factory has a manufacturing area of
over 15,000 m2 and is equipped with thermal, acoustic and
aeraulic test facilities.
The 9,000 m2 workshop DeCardenas Ventilazione in Arcore
increased this realty in 1997.
Eighty technicians work on the four main production lines:
- Ventilation,
- Heat-exchange,
- Air pollution control,
- Industrial noise protection.
In 1993, the Quality system was certified as conforming with
ISO 9001.
1
Supplies are exclusively tailor made according to the specific
requirements of various international customers, present in all
the main industrial sectors.
The experience acquired in more than 90 years of continuous
activity and the flexibility both in designing and manufacturing
is considerable.
A wide range of materials are usually utilized: steel and copper
alloys, aluminium, titanium and plastic materials; more than
100 welding procedures have been qualified.
The products are subject to intermediate and final testing,
witnessed by the customers or delegate inspection
Authorities.
The policy of the group is always more customer
focused.

To find the best performance for each
case ensuring high transfer coefficient
combined with low pressure drops
Boldrocchi provides several types of
helically finned tubes.
A variety of base tubes: from 1/2 inch to
2 inch diameters and different metals
such as carbon steels, stainless and
special steels, copper alloys, aluminium
and titanium can be finned with several
sizes and materials to satisfy customer
and design requirements.
Based on nine different finning machines
Boldrocchi can supply three basic
configurations on finned tubes.
- Footed fins: tension wrapped onto
the base tube. Also available: knurled
footed fins and overlapped footed
fins to ensure better heat transfer.
- Embedded fins: are tension wound in
a spiral groove, not more than
0,30 mm deep, into the base tube. A
strong joint between fin and tube is
ensured to allow excellent heat
transfer also at high operating
temperatures.
- Extruded fins: a smooth core tube is
inserted into an aluminium tube and
then fins are extruded out of the
aluminium tube.

Boldrocchi Ecologia is often called to restructure or expand plants that have
been in service for many years and whose efficiency is no longer in line with
the current regulations.
In these cases, we have designed special solutions that recover and make
the most of the existing plant, replacing the filtering systems with others
based on a modern design and providing an improved performance.
Even electrostatic precipitators can be repaired and made more powerful
using avant-garde internal equipment produced on the basis of a SPEIC (F)
licence.

teelmaking
The production of steel, whether a blast furnace or electric furnace is used,
results in the pollution of huge volumes of air which must be collected and
purified.
The in-depth knowledge of the cast iron and steel working processes enables
Boldrocchi Ecologia to make accurate forecasts about the volumes and
temperatures of the smoke with a view to identify the most suitable
design for the cleaning system.
The extraction of gases at extremely high
temperatures requires water-cooled tubular
walled ducts, while the elimination of the
heat from the smoke requires tube nest or
evaporating exchangers. Boldrocchi Ecologia
has a great deal of experience in the
construction of these devices which it
designs within the company to ensure
maximum reliability.
Smoke purification is carried out by bag
filters capable of reducing emissions to a
concentration of a few milligrams;
sometimes large electrostatic precipitators
are preferable due to their remarkable
resistance to wear over time.
Boldrocchi fans ensure that the extraction
plants operate continuously and reliably
with a maximum energy saving.

The dust is collected, transported and accumulated by means of mechanical
or pneumatic systems, always hermetically sealed to prevent the risk of
pollution of the environment.
The full automation of the plants is based on the use of advanced PLC’s and
is designed and implemented by our specialists according to the Customers’
requirements.

entails paying great attention to the
control of gaseous emission, Boldrocchi
Ecologia manufactures gas treatment
systems divided into various sections
capable of removing all the pollutants
selectively.
Electrostatic precipitators, dry and
semidry systems, bag filters,
neutralizing scrubbers, condensation
processes, together with the action of
additives such as lime, soda,
bicarbonate, activated carbon, etc. are
used to ensure an emission level that
complies with the strictest regulations.
