n the 3rd of March 1909 LUIGI BOLDROCCHI establishedthe 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 axialfans, fire-tube boilers, coolers, dryers, ventilating and heat-exchange unitsand plants.In 1926, the licence for the manufacture of finned tubes was acquired inthe USA and the manufacture of extended surface heat-exchangers wasdeveloped.In the twenties and thirties the company becomes a regular supplier of themain Italian industrial groups, the Ministry of Defence, naval yards andState Railways.The first air conditioning equipments for industrial and civil use weredeveloped; 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 standardproduction to concentrate on tailor made equipment for specificindustrial fields such as: power generation, the electromechanicalindustry 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 thecompany to introduce a Quality Assurance System.From then on, the product range has been enlarged, particularlyfor air coolers and steam condensers.In the environmental field, two independent divisions havebeen established:Aeroto, part of the group since 1994 keeps the originalname of the company Aeroto, active since 1952 in industrialnoise protection and gas turbine ancillaries.Ecologia, a fusion of our traditional technology with theexpertise of De Cardenas, purchased in 1997 and active since1926 in air pollution control and industrial fans.Completing our own structure and know-how with those onesof De Cardenas and Marelli Ventilazione, Boldrocchi hasbecome the heavy-duty fan leader in Italy.

Boldrocchi Ecologia applies newly designed bag filters andelectrostatic precipitators for purifying process smoke fromcement end lime kilns.Many slakers, clinker coolers, screening systems, productensilage and loading systems have also been equipped withhigh-performance dry filtration systems.When required due to the temperature of the smoke, forced-air tube nest exchangers or water fog evaporating towerscan be supplied.

Industrial steam generators, including those running onunconventional fuels, are equipped with smoke purificationsystems which combine extreme ease of operation with ahigh degree of efficacy in eliminating ash and any acidicpollutants.For large thermoelectric power plants Boldrocchi Ecologiahas extremely reliable gas purification equipment, based onelectrostatic precipitator and bag filter technology.The ash collected can be accumulated using safe andefficient pneumatic transport systems.

The production of energy by burning wasteentails paying great attention to thecontrol of gaseous emission, BoldrocchiEcologia manufactures gas treatmentsystems divided into various sectionscapable of removing all the pollutantsselectively.Electrostatic precipitators, dry andsemidry systems, bag filters,neutralizing scrubbers, condensationprocesses, together with the action ofadditives such as lime, soda,bicarbonate, activated carbon, etc. areused to ensure an emission level thatcomplies with the strictest regulations.

Iron foundries and non-ferrous metalfounding and refining companies useBoldrocchi Ecologia plants for purifyingthe smoke emitted by all types ofsmelting furnaces, both electric anddirect-fired. The great experience gainedin the cooling of dusty gases and thefiltering of highly aggresive smokeensures that the customer can chooselong-lasting devices and filtering means,which comply with the emissionregulations even for the most harmfulmetals.

S teelmakingThe 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 andpurified.The in-depth knowledge of the cast iron and steel working processes enablesBoldrocchi Ecologia to make accurate forecasts about the volumes andtemperatures of the smoke with a view to identify the most suitable design for the cleaning system.The extraction of gases at extremely hightemperatures requires water-cooled tubularwalled ducts, while the elimination of theheat from the smoke requires tube nest orevaporating exchangers. Boldrocchi Ecologiahas a great deal of experience in theconstruction of these devices which itdesigns within the company to ensuremaximum reliability.Smoke purification is carried out by bagfilters capable of reducing emissions to aconcentration of a few milligrams;sometimes large electrostatic precipitatorsare preferable due to their remarkableresistance to wear over time.Boldrocchi fans ensure that the extractionplants operate continuously and reliablywith a maximum energy saving.
