The company DUP deals in used stationary screw compressors from renowned manufacturers including Atlas Copco, Kaeser, Boge, CompAir, Almig, Alup, Ingersoll Rand and Gardner Denver. Several hundred used compressors and compressed air dryers are readily available from our warehouse in Hohenems (Austria). Oil-free compressors from Atlas Copco’s Z range form a central area of DUP’s expertise.
DUP Compressors is Europe’s market leader in the purchase and sale of used industrial compressors and compressed air dryers. DUP also supplies replacement parts for purchased screw compressors, rotary tooth compressors, compressed air refrigerant dryers and compressed air adsorption dryers. DUP works independently of manufacturers and supplies original spare parts from CompAir. DUP Compressors’ customers include resellers and industrial companies in more than 100 countries around the globe.
Close to 30 years of experience in trading with used compressors and dryers
For almost 30 years now DUP Compressors has been dealing in used compressors and dryers from various manufacturers including Atlas Copco, Kaeser, CompAir and Boge. DUP purchases used compressors and dryers predominantly from industrial companies that are replacing their compressor units, or from traders and compressor manufacturers throughout Europe. Our team of highly qualified technicians inspects, repairs and refurbishes some of these compressors which still offer many years of dependable service operating at full capacity. Other used compressors remain uninspected and are sold in an unchecked condition to importers in Africa, South America and Asia.
These machines are cleaned and inspected and any defect parts are replaced. Subsequently, the compressors and dryers are given a test run. We can offer demonstrations of checked compressors under power to customers here in our workshop. We do not, as a rule, carry out a new maintenance service since our customers are predominantly dealers who prefer to perform the maintenance themselves and for whom this option is more economical. On request DUP can, of course, carry out a maintenance service and complete overhaul on any machine. All checked compressors are despatched free from defects and come with an operational guarantee.
Work is carried out by qualified service technicians in our in-house workshop in accordance with manufacturers’ specifications. A test stand for compressors with a driving power of up to 500 kW has been installed especially for this purpose. The results of the test run with operational parameters are recorded. DUP guarantees the dispatch of a fully functional compressor unit.
These compressors and dryers are available for purchase in the condition they were taken out of service. These machines are given a visual check only; no inspection is carried out. The electric motor and air end are turned by hand. The overall condition is outlined as accurately as possible. Most of these compressor and dryer units are more than 10 years old, or are models from lesser known manufacturers. These compressors are purchased mainly by dealers outside of Europe. We do not recommend that users purchase these units.
DUP offers a cost-effective solution particularly suited to dealers.
