Atlas Copco enters new compressesors of screw with injection of oil for marine applications

Compressesors tested and certificates for the marine industry

Editorial Interempresas05/11/2012

Atlas Copco Marine presents two new ranges of compressesors of screw with injection of oil refrigerated by water, tested and certificates for marine applications. The BUT GA 55-90 PP offers a power of 55 to 90 kW. The BUT G 180-315 is an extraordinary compressesor of screw with injection of oil of a stage with powers of 180 to 315 kW. Both compressesors are open units, have some dimensions reduced and a high energetic efficiency

Both ranges offer the reliability and the efficiency of the technology of rotary presses screw with injection of oil of Atlas Copco. They are robust units, with a simple design, dimensions reduced and instrumented with the last controller Elektronikon Mk5 and second unemployed retardada, that minimises the time of operation of the engine of accionamiento. Both ranges are refrigerated by water, already was with freshwater (until 40 °C in the aspiración) or with water of sea, and deliver with the certification OMI for his integration in ships. The two units deliver with all the certificates of classification more important.

The compressesors are instrumented with all the functions that demands the marine industry, for example: topes of door, warming of the electrical engine, fireproof cables without halógenos, electrical cupboard presurizado, shock-absorbers of silent vibration, oil totally synthetic, filters of air, etc. The BUT GA and G are ideal for any demand of air: like air of general work, air of reinforcement for nitrogen, treatment of waters of ballast and manipulation of products to granel.

BUT GA 55-90 Power Pack - energetic Efficiency and performance

Based in the extraordinary GA 30-90 (VSD) of Atlas Copco, the compressesor of screw with injection of oil of BUT GA 55-90 Power Pack contributes an exceptional efficiency to the marine industry. With a new element of screw of accionamiento direct, low drag of oil and dimensions reduced (1,52 m x 1 m), this open unit combines performance and energetic efficiency. Even to high temperatures acclimatise of 55 °C, the BUT GA 55-90 PP offers a FAD (free air supplied) of 554 and 864 m³/h, measured in the brida of exit. This open unit works with some inferior audible levels to 88 dB. The BUT GA also is available as BUT+, with start crashes/standard triangle and like GA BUT VSD, that allows some savings of power of 35% by half term.

BUT G 180-315 - exceptional Performance with some dimensions reduced

The BUT G180-315 are designed to offer the greater reliability and efficiency, but keeping a big simplicity of installation and operation. The range covers several sizes of power in two dimensions: the BUT G180, 200, 250 (2,5 m x 1,250 m x 1,954 m) and the BUT G315 (2,669 m x 1250 m x 1954 m), with a free air supplied of until 2.422 m³/h. This intelligent design employs fewer pieces and almost any external pipe, to delete the risks of failure. The limited number of spare pieces also contributes to keep to the minimum the costs of maintenance. With his tray of standard oil, the BUT G180-315 offers to the dockyard the opportunity to facilitate the installation. The heart of the BUT G180-315 is the element of screw with injection of oil recently designed. With a holgura of less than 0,02 mm, guarantees “the best performance of the market”. The compressesors are of accionamiento direct and go mounted on shock-absorbers of silent vibration that guarantee a big reliability of the threads.
