PRODUCT OVERVIEW

About this gear

C-NITROX 400 is a single-membrane nitrox production unit with a ten-bar screw compressor. A separate high-pressure compressor is required to turn its enriched output into a cylinder-filling installation.

Consider before buying

The 199 kg cabinet is smaller than the 700 and 800, but mixture and delivery requirements still determine the pairing. Coltri’s table pairs 40% with a 315 L/min Efficient or Prime compressor; the 1,070 L/min feed figure is not cylinder-filling output.

Our take

Start here when the smaller cabinet and its matched-system capacity suit the filling centre. Compare the 800 for a larger installation requiring 40% mixtures. Include analysis, maintenance and commissioning in the buying decision, not just the cabinet price.
