Air compressors - Import export

Find Air Leaks. Decrease Energy Consumption. Maximize Uptime. Compressed air is the most versatile and therefore widely used resource in industry. Using atmospheric pressure to transfer energy during industrial processes, compressed air can be found powering air tools like drills and hammers, hydraulic air cylinders for automation in manufacturing processes and much more. Compressed air is also used to power air brakes on mobile fleets and trains. Air Compressor Expenses It is so commonly found in industry it is often referred to as the fourth utility to electricity, water and gas. Of the four, compressed air consumes the most energy. Air compressor systems can differ very greatly in size, output and cost. What remains constant, is the initial investment in a compressor system is only 25% of the expenses associated with it, over its lifetime. The other 75% of the costs go to energy used to compress the air.

Acoustics Rich and powerful acoustic features for your simulation needs Actran Acoustics is the foundation module of the Actran family and is both a standalone tool and a pre-requisite for advanced modules like Actran VibroAcoustics, Actran AeroAcoustics or Actran TM. Actran Acoustics contains a wide set of acoustic modeling features making it the CAE tool of choice for simulating a large variety of problems, from the simplest component to the most elaborate system. The Actran Acoustics product relies on Free Field Technologies’ exclusive powerful, robust, fast and reliable acoustic finite and infinite element library. Sound fields in cavities are easily analyzed with Actran Acoustics which offers both modal and physical approaches. Absorbing walls may be modelled in detail using impedance conditions or porous material models. Actran Acoustics is also uniquely suited for sound radiation analysis where it brings unprecedented efficiency, speed and productivity to your analysis process. Actran Acoustics features seamless interfaces with most FEA structural analysis codes like NASTRAN, ABAQUS™ or ANSYS™. Actran Acoustics also offers powerful features for analyzing sound propagation in ducts and may be used for designing e.g. intake and exhaust lines or air distribution systems in buildings, aircrafts and cars. Among the many advanced features available in Actran Acoustics are the handling of a mean flow field (convected acoustic propagation) and temperature gradient effects. Specific elements are also available to handle visco-thermal effects important when sound waves propagates in narrow ducts or thin cavities (eg: hearing aids, solar array panels, etc.). Pressure field generated by the vibration of a powertrain. Target Applications: Sound radiation by vibrating structures: powertrain, engine components (oilpan, intake manifold and air filter, valve cover, etc.), compressors, electrical motors, loudspeakers and more. Intake and exhaust noise, including complex mufflers and silencers. Air conditioning units and distribution systems (calculation of transfer matrices coefficients). Sound absorption inside passenger compartment of cars, trains and aircrafts. Sound propagation in complex media with mean flow or temperature gradient. Audio devices such as telephones, hearing aids or musical instruments.
