FANS AND BLOWERS:


In the years Boldrocchi has developed a wide experience in double or multi stage blowers with pressure rise over 9000 mmH20, double driven fans with steam turbine as main driver and electric motor as back-up, fans designed for pressures of several bars, fans manufactured in special alloys, casing with steam tracing to avoid acid condensates.
Fan and blowers are designed and manufactured to respect clients’ specifications and the main international standards as API 560 and API 673.

TESTS
High flexibility in testing equipment is one of the plus that Boldrocchi can offer to his customers; performance tests (according AMCA 210 or other standards) with ducts up to 3 m, running test at full speed for fans larger than 3 MW, complete unit tests with medium voltage motors of different voltage, pressure tests, hot gas tests and more.

MATERIALS
All the welding are performed according ASME, AWS or EN norms, with practically no restriction on the type of materials; carbon steels for very high or very low temperatures, different type of stainless steels, duplex and superduplex, Inconel, titanium.

AIR COOLED HEAT EXCHANGER


Specializing in providing all Thermal & Mechanical design, this division supplies tailor made air cooled heat exchangers (ACHE). Typical application are in plants for:
- Hydrocracking;
- Gas sweetening and acid gas removal ;
- TEG regeneration.

and to cool lube oil, gas and water for main equipment as:
- heavy duty gas compressor
- primary pumps
- gas turbines

Low noise applications, low temperature solutions and winterization for external air recirculation can also be provided by Boldrocchi.

In 1927 Boldrocchi manufactured the first finned tube and now thanks to the 11 different finning machines can supply finned tubes of different types:
L-footed
KLM
extruded
embedded
up to a finned length of 16 meters and in a variety of materials.

DESIGN AND TEST FOR PRESSURES UP TO 400 BAR
The tube bundle are mechanical and thermal designed for high pressure (up to 350 bar) in special materials such as Superduplex, Monel, Hastelloy and Titanium and for heavy service such as Wet H2S, Hydrogen and Fluor.

DESIGN WITH H.T.R.I SOFTWARE Thermal design is performed within Boldrocchi using H.T.R.I software and generally in accordance with API 661. Mechanical design of the pressure parts can be performed by Boldrocchi according to the main international codes (ASME, EN13445, AD Merkblatt, CODAP, VSR, etc.); FEA analysis can be performed for parts not covered by these codes. NACE, EEMUA and TEMA are also available.

Boldrocchi has a comprehensive ACHE Reference List which will show all previous contracts and Engineering Companies they have worked with.

DAMPERS


Custom-designed dampers are built according to critical operational requirements, depending on pressure, temperature, sealing degree and airflow regulation. Boldrocchi has its own technical knowledge to manufacture dampers in highly corrosive, abrasive and elevated temperature environments. The Company offers:
• 3D design
• FEM mechanical calculation
• Fluid dynamic simulation
• Noise analysis 

Boldrocchi performs, in its own workshops, tests for dampers in the presence of the Client before the shipping, achieving the overcoming of all the tests required by the stringent Customer specifications.
