DELTA TWIN - series expanded
04/01/2005
DELTA TWIN stands for the new two-stage compressed-air units, which following costly research and development as series with totally 7 sizes can realize volume flows of 760 m³/h up to 2.450 m³/h as well as differential pressures up to 10 bar. The absolutely oil-free working screw compressor units are available as water- and air-cooled designs and cover motor sizes from 75 to 200 kW.
Series DELTA TWIN is designed for the conveyance of air and neutral gases and is especially applied in the industrial compressed-air production not only required as working- or process air for compressed-air tools and spray-coating plants, in the foodstuff industry and in chemical resp. physical processes but also as control air for pneumatic control systems and in many other branches.
According to users’ requirements of economical compressed-air production and in view of development, special emphasis has been put on the efficiency of the ‘heart’ of the units - the screw compressor, each existing as high- and as low pressure stage. Thanks to constructive modifications of the rotors and the housings a considerable efficiency increase of up to 7% of the compressors could be finally achieved compared with similar machines of competitors. Depending on electricity rate, motor rating and annual use of the compressed air unit a considerable saving potential for the user can develop.
For the adaptation to the varying compressed-air consumption the units made by Aerzener now offer an integrated frequency converter in the power cabinet (for the time being for 75 and 90 kW). This will save space requirement and costly connections. Besides this, in future even complete solutions with installed dryer can be offered. The absorption dryer especially designed for the DELTA TWIN-series distinguishes itself due to an excellent efficiency, as the compressed air generated is treated without any capacity reduction.
Another special feature of the oil-free compressor units is the drive via V-belts, with which a good speed adjustment and mainly, lower investment costs compared with directly driven compressor units can be realized. In addition, the usual maintenance work on this type of drive (manual retightening of the V-belts) can be avoided thanks to this new design of the Aerzener Maschinenfabrik. In view of Aerzen compressed-air unit the motor is installed on a hinged mounting plate always ensuring an optimum belt tension due to motor’s own weight. Even after longer operation periods - a manual retightening is not necessary anymore.
Further advantages of this innovative series DELTA TWIN are the compact and space-saving construction as well as several modification possibilities making individual customer solutions possible.
First presentation of series DELTA TWIN with integrated frequency converter and adapted dryer at the COMVAC in Hannover from 11th April until 15th April 2005 at the stand of Aerzener Maschinenfabrik GmbH in hall 27, stand C 16.
