HISTORICAL NOTES On the rd of March 909 LUIGI BOLDROCCHI established the activity with the first orders for the supply of ten centrifugal fans. In 9 the Officine Termo Meccaniche BOLDROCCHI was set up in Milano with an operating area of 000 square meters. In 9 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 9, the licence for the manufacture of finned tubes was acquired in the USA and the manufacture of extended surface heat-exchangers was developed. From then on, the product range has been enlarged, above all as regards air coolers and steam condensers, heavy duty lng. Luigi Boldrocchi (880-99) and process fans, gas turbine ancillaries and diverters. Founder of the Boldrocchi Company The recent acquiring and incorporation of several companies (Aeroto, Marelli Ventilazione, De Cardenas) allowed Boldrocchi to enter new market opportunities as supplier of air intake and exhaust gas systems for gas turbine and large fans for any industrial application. In 00 a J-V manufacturing Company has been setup in India. In 00 a Boldrocchi Ecologia India office has been setup in Pune to manage air pollution business. historical notes operations Fans and service Engineered fans Main applications After sale service Direct main customers Contacts D.I. high head centrifugal fan supplied in 9 Te chnical drawing of centrifugal fan

Historical notes operations Fans and service After sale service FANS Today Boldrocchi spans over a wide range of fan types, used in all industrial applications. The growing importance of these machines marked the steps of a continuous and quick technical evolution, to which Boldrocchi has perfectly adapted in terms of design and manufacturing capabilities. For instance, with the recent acquisition of the technical and production knowhow of Aeroto, De Cardenas and Marelli Ventilation Companies, Boldrocchi became an outstanding supplier, not only in Europe, in the heavy duty fans field. Synergies with Aeroto Dept. for acoustic treatment and with Boldrocchi Ecologia for gas dedusting are another strength point of Boldrocchi fan production. DESIGN, CONSTRUCTION AND TESTS The high performance fans, as requested nowadays, involve strict procedures throughout all stages of design, manufacturing and testing. As regards fans materials and in particular for the rotating parts, Boldrocchi foresees high-yield materials and corrosion/abrasion protecting coatings. Impeller and steel works calculations are performed on stress analysis for a proper sizing of all the details. Moreover the rotating parts are designed to avoid any resonance with the supporting structures. Boldrocchi manufactures its fans using certified materials. All weldings are carried out according to proper specifications by pre-qualified welders and with pre-qualified procedures. Stringent dimensional and ND tests are performed on all the portions and on the whole assembled fan. Impellers are carefully balanced on high-sensitivity balancing machines. Large Fan Heavy duty process fan for industrial application Performance test Test room in Biassono workshop as per AMCA 0
Historical notes operations Fans and service R & D A deep search based on software finite element calculations allows Boldrocchi to choose the proper size and materials of designed fan, in order to match the customers requirements. In our test room tests are carried on in compliance with international standards, even on fan prototypes, in order to point out their performance curves: flow rate-pressure,flow rate-power,flow rate-noise level. The experimental data are processed by the Engineering Department to optimize the fans series. Special tests are performed, on case by case basis, to verify the fans performances, even assembling specific test rigs. PROCESS ENGINEERING AND SERVICE Thanks to an extended experience in the ventilation business, Boldrocchi is able to supply to customers a valuable and reliable engineering consultancy service, on already installed fans, to increase performances, to comply with environmental rules, and to save energy, either on own production fans or on fans supplied by other manufacturers. This service integrates the after sales service, dedicated mainly to periodic and predictive maintenance, mechanical troubles diagnostic and solution, dynamic balancing of rotors on site and erection /supervision.
