    The Boldrocchi group now comprises various companies inthe world that can offer solutions for different production lines.The group employs 300 people, 150 of which work inproduction. The Biassono factory has a manufacturing area ofover 15,000 m2 and is equipped with thermal, acoustic andaeraulic test facilities.The 9,000 m2 workshop DeCardenas Ventilazione in Arcoreincreased 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 withISO 9001.

    Supplies are exclusively tailor made according to the specificrequirements of various international customers, present in allthe main industrial sectors.The experience acquired in more than 90 years of continuousactivity and the flexibility both in designing and manufacturingis considerable.A wide range of materials are usually utilized: steel and copperalloys, aluminium, titanium and plastic materials; more than100 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 customerfocused.

    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.

    Eng. Luigi Boldrocchi(1880-1949),founder of theBoldrocchi Company.

    With the help of on going research anddevelopment, Boldrocchi continues to improve itsproducts. A computer aided design networkspeeds up technical work and enable engineers to examine different approaches and to reach thebest solutions.

    All projects involve a process of:- thermal design according to current and wellestablished operating techniques;- mechanical design according to the mainstandard codes such as TEMA, ASME, API;- structural and stress analysis with finiteelement method;and, finally, the choise of the best solutionrespecting the required noise level, whilstoptimizing the required power, ensuring easytransportation, installation and maintenancecombined with competitive prices.

    heat exchangers

    The atmosphere is the cheapest and widest spread medium for coolingin most industrial processes.When manufacturing the first finned tubes in 1926, Boldrocchi began todeal in extended surface heat exchangers using the air as a coolant.After several decades of experience, the Company is today able to supply awide range of air cooled heat exchangers, used worldwide in utilities andindustrial applications; serving the petroleum, chemical, gas processing,electrical, power generation, environment and steel industries.From small coolers for endothermic engines, for compressors and dryers u
