How we calculate scores →About this gear
C-NITROX 700 combines a twelve-bar screw compressor with a single membrane to supply enriched gas to a separate high-pressure compressor. Coltri specifies mixtures up to 36% oxygen for a correctly matched installation.
Consider before buying
The published pairing table changes compressor capacity with the target mixture: 30% is paired with Heavy Duty 750, 32% with 650 and 36% with 450. The 2,000 L/min feed specification should not be read as the final nitrox output.
Our take
A candidate for a filling operation whose mixture requirements fit within 36%. Compare the twin-membrane 800 if 40% is required. The purchase decision should include the matching high-pressure unit, electrical work and trained commissioning.
