Electric compressors - Import export

Electrical connections between motor, control cabinet air dryer and water pump. Specific electric motors : protection degrees, IP23 or IP55. Efficiency class : IE1, IE2, IE3. Different optional voltage and frequencies, standard is 400V/3/50HZ or 60HZ +/- 10%. Other voltage is on request : 380V/3/50Hz or 60Hz, 575V/ 60Hz… Soft starter SIEMENS SIKOSTART. Standard is Star Delta starter, the optional soft starter is integrated in the main electrical control cabinet. The compressor is equipped with an electrical pre-lubrication oil pump for the crankcase. Air-conditioning for electrical control cabinet for inside temperatures exceeding 40 for soft starter & 45°C for standard electrical cabinet. The frequency inverter electrical cabinet is protected against high temperature through a different selection of internal components (powerblock…).

Evaporative closed loop cooling towers : For temperatures above 32°C. Cooling capacities are selected to suit the local site wet bulb temperature, up to 30°C ( Wet Bulb ) to provide the most efficient cooling system. The tower and the water pump are controlled by the compressor’s electrical cabinet. Option : two speeds fan motor for winter and summer, antifreeze protections, tracing. Radiator cooling systems. Selected for maximum ambient temperatures up to 32°C, other selections accepting temporary heat peaks up to 36°C and 40°C during some hours per day. These specific versions are equipped with an automatic spray system with thermostatic control The radiator fans and the water pump are controlled by the compressor’s electrical cabinet. The water pump. is mounted on the compressor’s base plate. The cooling system, its functions (automatic spray system for radiators and antifreeze protections for cooling towers) and the water circulating pump are thermostatically monitored by...

Detecting mechanical faults before they stop production Bearing and Machine Maintenance Industry runs on machinery. Bearings, pumps, electric motors, compressors, presses, gearboxes and much more. All of which can break unexpectedly, causing production to stop. When production stops your organization loses money. Few bearings make it to the end of their engineered lifecycle. This is due to poor workmanship, bad lubrication practices and neglect. Problems can even arise right after installation due poor installment of the machine. No two machines are the same. Across industry, machines operate under different loads, climates and conditions, making their maintenance requirements unpredictable. Many machines are still maintained on calendar based PM’s, while others are run-to-failure. Both strategies are wasteful.

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.
