Why insist on an Atlas Copco oil-free solution for your oil or gas installation?
For increased safety, smooth-running control systems and processes, and higher product quality.

Hazardous processes: increased safety and security
Compressed air is often used to purge EEx p type control panels to maintain area safety. The presence of even small traces of oil can create a fl ammable situation, and more critically a platform shutdown and evacuation.

Control/Instrument air: increase uptime, lower costs
Compressed air is used to operate and actuate specifi c instruments and control valves. Even a small amount of oil in compressed air will cause the malfunctioning of this responsive equipment. Maintenance means downtime and increased costs. Oil injected compressors need regular oil filling and frequent fi lter changes to prevent air contamination and serious shutdown conditions.

Nitrogen generation: purer gas, less downtime
Separated using membrane technology, compressed air provides the nitrogen blankets critical in LNG tankers, transfer stations or the catalysts and reactors in a downstream segment application. Oil-free compressed air assures longer membrane service life, which avoids frequent and costly membrane replacements and potential shutdowns.

Buffer air: prevents main process/gas compressors from shutting down
High flow gas and process compressors require buffer air between seals to ensure proper performance. Even a slight presence of oil fumes can spell disaster and lead to main compressor shutdown.

First-generation drives and controls: assure trouble free equipment operation, of any age.
First-generation drives and controls rely on compressed air for proper operation. Oil in the compressed air will block critical operating components and increase operational risk.

Process operation: no oil, no problems
Compressed air is used in sulphur removal, catalyst regeneration, process heaters, sour-water oxidation and gasoline sweetening, to list a few. A trace of oil in these processes creates a risk of contamination, malfunction and problems.

Calibration and test equipment: prevents contamination and faulty readings
Instrument and safety valve test benches and liquid/gas analyzers often use compressed air instead of nitrogen for calibration. The presence of oil in compressed air will clog precise equipment, falsifying initialization settings.
