heat exchangers
On 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 setup in Milan with a manufacturing 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 radialand axial fans, fire-tube boilers, coolers, dryers, ventilating andheat-exchange units and plants.In 1926, the licence for the manufacture of finned tubes wasacquired in the USA and the production of extended surfaceheat-exchangers was developed.In the twenties and thirties the company becomes a regularsupplier of the main Italian industrial groups, the Ministry ofDefence, naval yards and State Railways.The first complete equipment to cool a power transformer wasdeveloped and supplied in 1931.
In the post-war period, the activity was carried on by GIULIANO BOLDROCCHI who progressively abandoned standard production to concentrate on tailor made equipment for specific industrial fieldssuch as: power generation, electromechanical industry and major shipbuilders.In 1970, a new factory was built and, with some later extensions, forms the present headquarter.In the early 80’s, supplies for the nuclear sector induced the company to introduce a Quality AssuranceSystem. From then on, the product range has been enlarged, particularly for process air coolersand 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 since1952 in industrial noise protection and gas turbine ancillaries.Ecologia, a fusion of our traditional technology with the expertise of De Cardenas, purchased in 1997and active since 1926 in air pollution control and industrial fans.Boldrocchi has become a heavy-duty fan leader in the world making the most of its centenary expertisewith the ones of De Cardenas and MarelliIn 2006 a joint-venture manufacturing company has been set up in India.

In three separate workshops with a total 27.000square meter manufacturing area, Boldrocchiemploys 300 staff, among which 100 aretechnicians.The shops are equipped with thermal, acousticand aeraulic test facilities.
Boldrocchi production is divided into four mainlines: heat exchange (exchangers and coolers),fans, industrial noise protection and air pollutioncontrol. Today production is featured by highlyspecialised technical contents, many decades of'on site' experiences, flexibility in design and inproduction together with high quality standards.Supplies are tailor made to fulfil all Customers’specific requests. Boldrocchi Quality system iscertified according to ISO 9001 since 1993 andaccording to ASME Code since 1998.
A wide range of materials are usually used: steel and copper alloys, aluminium, titanium and plasticmaterials; more than 200 welding procedures have been qualified. The products are subject tointermediate and final testing, witnessed by the Customers.

During 1931 Boldrocchi tested and manufactured the firstOFAF transformer oil cooler and since 1948 an engineeringdepartment has been exclusively devoted to large electricalmachines cooling:
Static electrical machineLarge power transformersDistribution transformers ReactorsIndustrial and furnace transformers
Rotating electrical machineMotorsGenerators
More than seventy years of experience in this specific fieldallows Boldrocchi to offer each customer the best solutionsmatching all the requirements and to optimize reliability,performance and costs.
Test facilities are equipped to check the thermal efficiency ofthe coolers by using dielectric oil or water and air toguarantee a reliable know-how and the requestedperformances.
The most used coolers’ prototypes have been approvedwith thermal and noise tests witnessed by official boardsand customers.
A distinctive feature of Boldrocchi lies in its ownexpertise to design and to manufacture all themain components of a cooler: the finned tubes,the heat exchanger, the fan, the circulatingpump and the electrical devices.
More than 15.000 Boldrocchi Oil Air coolers have beensupplied in the latest fifty years.

The transformer oil is warmed by the heat losses of thewindings.
The oil is conveyed into the shell side of the cooler.Baffles are used to lead the oil flow around the tubes incross flow. The cooling side on the tube side is divided intwo or more paths. Two water paths are usually used.
Features of single tube cooler executionWhen using the single tube coolers the oil pressure mustexceeds the water pressure in any operation, to avoidwater infiltration into the oil circuit in case of leakage.
Features of double tube cooler executionUnlike single tube coolers, this execution of the tubebundle requires double tubes and doubled tube-plates.This special safety design enables the operation withcooling water pressure not limited by the oil pressure.Double tube coolers in standard design are suitable for awater pressure of 10 bar.
In case of leakage, water or oil are led into the chamberbetween the double tubes and the two tube plates,therefore the double tube system always prevents waterand oil from mixing.
The double tube design is the most valid solution toprotect the transformer, especially when, using sea orindustrial water, the site maintenance is not easy. Shoulda leakage happen, an alarm is provided by a magneticfloat switch screwed to a collecting box fitting the cooler.
